Full textAbstract:
It has been known that the chicken’s resistance to disease was affected by chicken’s genetic background. And RLR-mediated antiviral pathway plays an important role in detection of viral RNA. However, little is known about the interaction of genetic background with RLR-mediated antiviral pathway in chicken against MDV infection. In this study, we adopted economic line-AA broilers and native Erlang mountainous chickens for being infected with MDV. Upon infection with MDV, the expression ofMDA-5was upregulated in two-breed chickens at 4, 7, and 21 d.p.i. It is indicated that MDA-5 might be involved in detecting MDV in chicken. Interestingly, the expression ofIRF-3andIFN-βgenes was decreased in spleen and thymus of broilers at 21 d.p.i, but it was upregulated in immune tissues of Erlang mountainous chickens. And the genome load of MDV in spleen of broiler is significantly higher than that in Erlang mountainous chickens. Meanwhile, we observed that the death of broiler mainly also occurred in this phase. Collectively, these present results demonstrated that the expression patters ofIRF-3andIFN-βgenes in chicken against MDV infection might be affected by the genetic background which sequently influence the resistance of chicken response to MDV.

This study aims to determine: (1) the factors that influence the production of broiler chicken farming, (2) the effect of broiler chicken business management on production, and (3) the effect of murotal Al-Qur'an and other production factors on production. This research was conducted in Malang Regency, with the consideration that Malang Regency is one of the three (3) big broiler-producing districts in East Java. As the unit of analysis is primary data from interviews with broiler breeders who were selected as respondents. The analysis tool uses multiple linear regression models using the natural form (Ln). The results showed that: (1) The production of broiler chicken farming was positively influenced by the number of seeds, the amount of feed, business management, business capacity, murotal Al-Qur'an and the volume of business above the average. Broiler chicken production is negatively affected by the area of the house, the number of dead chickens, and the number of abandoned chickens. Independent variables that do not affect the production of broiler chicken farming are the management of broiler chicken raising and the number of person working days (HKO). To increase production, it is necessary to increase the number of seeds, the amount of feed, optimize the area of the cage, reduce the number of dead chickens, reduce the number of dead chickens, improve business management, increase business capacity, utilize murotal Al-Qur'an and with business volume above average.

Full textAbstract:
<p class="awabstrak2"><span lang="EN-US">Heat stress is an important issue in broiler chicken farms in tropical countries, such as Indonesia. Heat stress is very detrimental to broiler chickens because reducing production performance, health, and causing mortality. In the condition of heat stress, broilers synthesize Heat Shock Protein (HSP) quickly as the body's response to heat stress. HSP 70 is the most studied HSP group related to heat stress. The objective of this study was to review the nutritional approach that has been done to mitigate heat stress in broiler chickens with the HSP70 gene expression as its indicator. Based on some studies, nutritional approaches that can be taken are through the management of feed availability, supplementation of vitamin C, vitamin E, plant bioactives, amino acids (taurine and glutamine), probiotics, prebiotics, synbiotics, manan oligo saccharide (MOS) and minerals (selenium, zinc, manganese, chromium). By these approaches, HSP70 gene expression decreased indicating that the heat stress level of broiler chicken also reduced. It can be concluded that the nutritional approach can be used as a method for heat stress mitigation in broilers with the HSP70 gene expression indicator. </span></p>

<p>The experiment was conducted to examine the influence of probiotic preparation on the mineral contamination of the broiler chicken muscles. Investigational product contains probiotic lactic acid bacteria of genus Lactobacillus and Enterococcus. It is proved that additional feeding of probiotic “Entero-active” to broiler chickens increases retention of mineral elements of the fodder. To study the effect of probiotic on chicken meat the contamination of minerals in the experimental poultry meat was researched. The studies proved that the additional use of the studied probiotic supplements with food of broiler chickens allowed increasing phosphorus contamination by 4.7%, magnesium by 3.9% and iron by 46.5% in the pectoral muscles compared with the control group. The use of probiotic for broilers feeding has increased phosphorus by 4.7%, calcium by 4.1 times, iron by 70.5%, zinc by 5.4%, magnesium by 31.5% and copper in 4.2 times in thigh muscles of poultry. Thus, consumption of probiotic preparation by broilers in various doses improves the mineral compound of meat carcasses this meat is also considered as free range food. It was proved that probiotic increases the synthesis of such essential amino acids in the pectoral muscles as lysine by 1.66%, histidine by 0.03%, arginine by 0.38%, threonine by 0.07%, valine by 0.16%, methionine by 0.33%, leucine by 0.1% and phenylalanine by 0.17%. The increasing of level of lysine and histidine respectively by 0.05 and 0.08% is observed in the thigh muscles of broilers under the influence of probiotic. We have proved that the optimal dose for broiler chickens is 0.25% for the age of 1-10 days, 0.1% for the age of 11-28 days, 0.05 % for the age of 29-42 days, the percentage is for broiler chickens feed weight. </p>

The purpose of the research was to clarify the effect of chicken broilers feeding in the composition of mixed fodder with Vitamins E and C on the cellular link of non-specific resistance of the organism and, in particular, the parameters of pseudoiesinophils phagocytosis in blood. The research was carried out on chickens broiler – 308 grown in the farm “Fedyuk M” in the Zolochiv district of Lviv region. The keeping of the chickens was cellular with free access to feed and water. Experiments were conducted in 4 groups of broiler chickens of 100 chicks in each according to the scheme: the control group was fed with the standard feed (SC) according to the existing norms recommended for the cross ROSS-308; the first experimental group in addition to the SC received vitamin Е 1g/10 kg of mixed fodder; the second experimental group received vitamin C 2.5 g/10 kg of mixed fodder; the third experimental groups in addition to the ration received Vitamin C 2.5 g/10 kg and Vitamin E 1 g/10 of mixed fodder. For carrying out of immunological researches in chickens blood was taken in different age periods: 27-, 34- and 41-day-old age. In the whole blood, the phagocytic activity of pseudoiesinophils (FA), phagocytic index (FI) and phagocytic number (FF) were determined. For research, the daily culture of Escherichia coli (strain VKM-125) was used. The stimulatory effect of vitamins E and C in the composition of mixed fodder for chicken broiler broilers on the indices of pseudoiesinophils phagocytosis of blood was determined. As evidenced by a significantly higher phagocytic activity, phagocytic index and phagocytic count of pseudoiselinophils in blood of chickens in the experimental groups by comparison with the control group. At the same time there was a direct correlation between phagocytic activity and phagocytic index and index in blood of chickens broiler in experimental groups. At the same time, the ability of blood pseudoiesinophils to phagocytosis of microbial cells was higher in chicken broilers, which were fed with vitamin E and C.

Full textAbstract:
Nowadays, the high demand for village chickens in Malaysia leads to the fraudulent substitution of indigenous chickens with other cheaper counterparts. Discriminating different chicken breeds based on their phenotypic characteristics is one strategy to avoid chicken adulteration. The main objective of this study was to authenticate and group dominant chicken breeds in Malaysia, including commercial chickens (Cobb, Hubbard, DeKalb) and cross-bred village chickens (Ayam Kampung, Akar Putra). The further discrimination of village chickens from underaged colored broilers (UCBs) (Hubbard, Sasso) was performed based on phenotype traits. The results showed that the breed had a significant effect (p < 0.05) on phenotypic characteristics, while the sex effect was not significant for some characteristics. In the first phase, the most remarkable discriminating factors were abdominal fat weight, breast muscle weight, chest circumference, shank length, and wingspan. However, in the second phase, notable variations in phenotypic characteristics between village chickens and UCBs were not detected. Principal component analysis (PCA) showed the successful separation of village chickens from high-performance breeds (broiler and colored broiler). Nevertheless, there was overlap among observations for Sasso and village chickens, which approved the possible similarities in their phenotypic characteristics. This study showed clear breed clustering, which leads to the chicken authentication based on their phenotypic characteristics.

The aim of this research was to evaluate the level of greenhouse gas emission from broiler chicken farming industry in Malaysia. In order to achieve that, Life Cycle Assessment method was chosen as a framework to complete the task. A case study was conducted at a broiler chicken farm to gather the data and information related to the broiler chicken production. Cradle-to-gate assessment including distribution stage was conducted based on the ISO14040/1044 guidelines. Inventory data for this case study was gathered in collaboration with one of the selected case study broiler chicken farm company. Greenhouse gas emission that consists of several most affected gases such as carbon dioxide, methane and nitrous oxide was studied. Result shows that the highest carbon dioxide emission came from manure, which accounted for 1,665,342 kg CO2 equivalent per total broilers while the highest methane emission came from feed, which accounted for 126,207.84 g CH4 equivalent per total broilers. For nitrous oxide emission, the highest values came from bedding which accounted for 20,316.87 g N2O equivalent per total broilers in the commercial modern broiler chicken farm. In this case study, it can be concluded that manure gives the most prominent effect to the greenhouse gas emission followed by feed and bedding materials.

The objective of this work was to investigate the use of a halothane to screen broiler chickens prone to develop PSE (Pale, Soft, Exudative) meat through a special gas chamber connected to a veterinarian anaesthetic apparatus developed in our laboratory. Anaesthesia was induced with approx. 3.0% halothane at a flow rate of 6.0 Lm-1 in pure oxygen for 5 min. Commercial male broilers (n=342) aged 46 days old were evaluated and classified as either halothane sensitive (HAL+) or insensitive (HAL-), depending on the leg rigidity response. Approximately 27.5% (n=94) of broilers were HAL+ and 72.5% (n=248) were HAL-. This is a simple and rapid technique to evaluate broiler sensitivity to halothane and identify broilers prone to develop PSE meat. The occurrence of PSE meat in HAL insensitive broiler chicken samples suggests that other factors are related to PSE occurrence.

Full textAbstract:
The acidifying agents are being used more often as an alternative to fodder antibiotics in order to preserve bird’s stock and increase productivity. We created the new liquid acidifier “Aquasan” for broiler chickens on the basis of organic and inorganic acids. The application of various feed additives or drugs to the diet of chickens leads to changes in the chemical composition of meat. The purpose of the paper was to research the slaughter qualities and the chemical composition of broiler chicken meat in case of feeding the stock with the “Aquasan” acidifier. The research was conducted on three groups of chicken broilers of the breed Ross 308 – 50 heads in each group. The first group of chickens was the control one, the second group of chickens was given the acidifier analogue called “FEEDACID MAX L”, and the third group was given the new acidifier “Aquasan”. The process of feeding of 0.1% of the working acidifier solutions was performed from the 27th day of fattening within 10 days (27th–31st and 34th–38th day). The growing period lasted 43 days. The moisture content of meat was determined by the method of drying, the content of protein – by the Kjeldahl method, total fat – by the Soxhlet method, the ash content – by the charring method. It has been established that the use of the “Aquasan” acidifier contributed to the increase in the productivity of broilers, the live weight of chickens on the 43rd day of breeding increased by 1.1 times (Р ≤ 0.05), and the weight of a carcass by 1.2 times (Р ≤ 0.05), in particular, by 310 g and 350 g, respectively. Also, the use of the acidifier allowed increasing the livability of chicken stock by 6% (Р ≤ 0.001). The average yield of carcasses of broilers increased by 4.4% (Р ≤ 0.05), which is 2% more than the standard values for this breed of chickens called Ross 308. With the use of the “Aquasan” acidifier, an increased content of dry matter in the broiler meat by 1.5% (Р ≤ 0.05) was noted and, accordingly, a decrease in the same percentage of moisture in meat. The protein content of chicken meat on the 43rd day of breeding increased by 0.9% (Р ≤ 0.05), ash increased by 0.3% (Р ≤ 0.05), and the fat content decreased by 0.4% (Р ≤ 0.05). Similar changes in slaughter rates and chemical composition of chicken meat were also observed in case of feeding the acidifier analogue “FEEDACID MAX L”; the difference compared with the new “Aquasan” acidifier was insignificant. Consequently, the feeding of the liquid acidifier “Aquasan” to chicken broilers from the 27th day of their breeding does not lead to deterioration in the quality of the slaughter and the chemical composition of poultry meat.

The use of intensive selection procedure in modern broiler chicken lines has led to the development of several skeletal disorders in broiler chickens. Therefore, current research is focused on methods to improve the bone quality in birds. In ovo technology, using nanoparticles with a high specificity to bones, is a potential approach. The present study aimed to evaluate the effect of in ovo inoculation (IOI) of calcium carbonate nanoparticles (CCN) on chicken embryo development, health status, bone characteristics, and on broiler production results and bone quality. After assessing in vitro cell viability, the IOI procedure was performed with an injection of 500 μg/mL CCN. The control group was not inoculated with CCN. Hatchability, weight, and selected bone and serum parameters were measured in embryos. Part of hatchlings were reared under standard conditions until 42 days, and production results, meat quality, and bone quality of broilers were determined. CCN did not show cytotoxicity to cells and chicken embryo and positively influenced bone parameters of the embryos and of broilers later (calcification) without negatively affecting the production results. Thus, the IOI of CCN could modify the molecular responses at the stage of embryogenesis, resulting in better mineralization, and could provide a sustained effect, thereby improving bone quality in adult birds.

The article presents research data on indices of lipid peroxidation (TBA–active products and hydroperoxides lipids) in the blood of broiler chickens on the background of vaccination and disease Nyukasla for the actions of vitamins E and C.The study was conducted on three groups of 100 broiler birds each. Control group fed normal chicken feed. The first research group in addition to poultry feed said received – tocopherol acetate in an amount of 0.1 g/kg feed, the second – ascorbic acid 0.25 g/kg feed. The third research group chickens – tocopherol acetate and ascorbic acid at these doses. For research use blood that was in the chicken after decapitation at different ages: 11–, 27–, 34– and 41–day age. The results of performance of different age groups broiler chickens compared with the value of the index poultry 11–day age for vaccination, and a control group of birds.Studies have shown that the content of intermediate and final products of lipid peroxidation in the blood plasma of broilers depends on the age and period of immunization. Feeding high amounts of vitamin E and C in the composition of feed for broiler chickens caused a reduction (p < 0.05 – 0.001) content in plasma lipid hydroperoxides and TBA–active products. PAUL likely lower rates of broiler chickens research groups suggest reducing the negative impact of stress factors on their bodies on the background of vaccination against the disease Nyukasla. These changes were more pronounced in the blood of chickens, which in addition to the basic diet receiving tocopherol acetate and ascorbic acid.

Employees of the Ternopil Research Station on the basis of organic and inorganic acids created a new liquid acidifier for broiler chickens called the “Aquasan”. It positively affects the preservation, productivity and constant microflora of the digestive tract in chickens. An important indicator of meat is its harmlessness and biological value. The purpose of the paper was to research the toxicity and biological value of chicken meat in case of feeding the stock with the “Aquasan” acidifier. The research was conducted on three groups of chicken broilers of the breed Ross 308–50 heads in each group. The first group of chickens was the control one, and the second group of chickens was fed with 0.1 % solution of the “Aquasan” acidifier from the 27th day of fattening within 10 days (27th–31st and 34th–38th days). The growing period lasted 43 days. Toxico-biological evaluation of chicken meat was carried out by express method using infusorias Tetrachymena pyriformis. Study of toxicity of pectoral and thigh muscles of the chickens have shown that within 24 hours of observing the infusorias, there was no death or inhibition of growth in an environment. Only on the 24th hour of observing in the experimental and control groups, there were infusorias with changes in shape and nature of movement in the amount of 0.1–0.2% cultures. The results of the research indicate that there is no acute and subacute toxicity of broiler meat in case of feeding the Acquasan acidifier. After 96 hours of research, 0.5–0.6 % of dead infusorias was found in samples of pectoral and thigh muscles in both groups. Also, there were infusorias with changes in shape and nature of movement on the 4th day, 0.3–0.4% and 0.2–0.3% respectively. There were no changes in growth of infusorias in the test group. Comparing the results of studies with control samples, it can be noted that the broiler chicken meat does not exhibit chronic toxicity. During 96 hours of research on the toxicity of chicken meat, no significant changes were found in the experimental group. Consequently, chicken meat from broilers grown with the use of “Aquasan” acidifier according to the express method is non-toxic, i.e. harmless for consumption. During the study of biological value of chicken meat, calculation of number of infusorias who grew up on the 4th day in the environment of the research samples of pectoral and thigh muscles, showed a lack of credible changes in their number as compared with the control. The absence of a reliable decrease in the relative biological value of meat indicates the high quality of the broiler chicken product in case of feeding them with the “Aquasan” acidifier.

Backgrounds: Broiler chickens are high productivity livestock. To achieve this productivity, many farmers provide feed additives. Fermented milk is one of the feed additives given through drinking water. Providing feed additives, regularly, will affect the performance of these broilers. Purpose: To investigate the potential of providing fermented milk through drinking water on the performance of broiler chickens. Method: Direct observations and perform calculations on several aspects that support the research. Result: After making observations, it was known that there are differences in the starter phase and the finisher phase. The observation was carried out from the age of 0-27 days. Broiler performance determined by the parameters of feed consumption, chicken body weight, and feed conversion. Conclusion: The observation shows an increase in feed consumption. However, in feed conversion and body weight gain instability is caused by physical conditions, temperature, and palatability in each phase of the broiler chickens.

The data about changes in neutrophils stimulation index in men blood after consumption of broiler chicken meat with the natural origin immunomodulators, introduced in feed before slaughter, is presented in this paper. Spleen extract biologically active substances were used as immunomodulators and anti-stressors during pre-slaughter period. Biologically active substances influence on putrescin, spermine and spermidine content in broiler chicken blood before slaughter and on some non-specific resistance indices in people was determined after consumption of broiler chicken meat. Two groups of broiler chickens at one month age were formed for the study. The spleen extract obtained with ultrasound application (I research group) served as biologically active substances was added to the feed of broiler chickens in pre-slaughter period (five days before slaughter). Blood polyamines such as putrescin, spermine and spermidine were determined by the method of High-performance liquid chromatography (HPLC) on the liquid chromatograph Agilent 1200 (USA). The second experiment was conducted on 10 people. We recruited 10 healthy male medical students (20 years old, on average) after the National Medical license examination. Spleen extract polyamines as immunomodulators and anti-stressors have the most effective influence on total quantity of polyamines in broiler chicken blood. As a result of research, it is found that aerosol introduction of spleen extract into broiler chicken feed reliably increases total quantity of polyamines by 39% and, in particular, spermidine concentration by 34%, and spermine by 40% compared with broiler chickens of the control group. Some non-specific body resistance indices in men blood upon consumption of broiler chicken meat varied within the physiological norm. The neutrophils stimulation index increased in men blood (+0,82) after consumption of meat of broiler chickens to which spleen extract as immunomodulator and anti-stressor was introduced before slaughter (experimental group). The neutrophils stimulation index decreased in men blood (–2,21) after consumption of broiler chickens meat at pre-slaughter stress (control group). The neutrophils stimulation index in men blood of experimental and control groups differed by 34,8%, but did not go beyond the physiological norm. At the final stage of poultry feeding it is necessary to consider pre-slaughter stress and to apply biologically active substances of natural origin, such as spleen extract. The results obtained in the experiment on broiler chickens can be used in studies of non-specific resistance indices of the farm animals for increasing the organism resistance, correction and avoiding of pre-slaughter stress and improvement of product quality

Among chicken strains, broilers are prone to pulmonary hypertension, whereas Leghorns are not. Relaxations to endothelium-dependent (ACh, A23187) and endothelium-independent [sodium nitroprusside (SNP), papaverine (PPV)] vasodilators were compared in preconstricted pulmonary artery (PA) rings from these chicken strains. ACh (10−7, 10−6, and 10−5 M)- and A23187 (10−6 and 10−5.5 M)-induced relaxations were smaller ( P < 0.05) in broilers than Leghorns. N G-nitro-l-arginine methyl ester (10−3.5 M) caused similar reductions in ACh-induced relaxations in both strains.l-Arginine (10−4 M) enhanced ACh-induced relaxations more in broilers than Leghorns. Relaxations to 10−10–10−6M SNP did not differ between strains, but were greater ( P < 0.05) in broilers than Leghorns at higher concentrations (10−5 and 10−4 M). PPV (10−4 M)- and SNP (10−4 M)-induced maximal relaxations were greater in broilers than in Leghorns (176.2 ± 14.7 vs. 120.9 ± 14.7% and 201.3 ± 7.8 vs. 171.2 ± 10.7%, respectively, P < 0.05). Broiler PA rings appear to have increased intrinsic tone and reduced endothelium-derived nitric oxide activity, both of which may contribute to the susceptibility of broiler chickens to pulmonary hypertension.

Full textAbstract:
The proper spatial distribution of chickens is an indication of a healthy flock. Routine inspections of broiler chicken floor distribution are done manually in commercial grow-out houses every day, which is labor intensive and time consuming. This task requires an efficient and automatic system that can monitor the chicken’s floor distributions. In the current study, a machine vision-based method was developed and tested in an experimental broiler house. For the new method to recognize bird distribution in the images, the pen floor was virtually defined/divided into drinking, feeding, and rest/exercise zones. As broiler chickens grew, the images collected each day were analyzed separately to avoid biases caused by changes of body weight/size over time. About 7000 chicken areas/profiles were extracted from images collected from 18 to 35 days of age to build a BP neural network model for floor distribution analysis, and another 200 images were used to validate the model. The results showed that the identification accuracies of bird distribution in the drinking and feeding zones were 0.9419 and 0.9544, respectively. The correlation coefficient (R), mean square error (MSE), and mean absolute error (MAE) of the BP model were 0.996, 0.038, and 0.178, respectively, in our analysis of broiler distribution. Missed detections were mainly caused by interference with the equipment (e.g., the feeder hanging chain and water line); studies are ongoing to address these issues. This study provides the basis for devising a real-time evaluation tool to detect broiler chicken floor distribution and behavior in commercial facilities.

The presence equipment (e.g., water pipes, feed buckets, and other presence equipment, etc.) in the poultry house can occlude the areas of broiler chickens taken via top view. This can affect the analysis of chicken behaviors through a vision-based machine learning imaging method. In our previous study, we developed a machine vision-based method for monitoring the broiler chicken floor distribution, and here we processed and restored the areas of broiler chickens which were occluded by presence equipment. To verify the performance of the developed restoration method, a top-view video of broiler chickens was recorded in two research broiler houses (240 birds equally raised in 12 pens per house). First, a target detection algorithm was used to initially detect the target areas in each image, and then Hough transform and color features were used to remove the occlusion equipment in the detection result further. In poultry images, the broiler chicken occluded by equipment has either two areas (TA) or one area (OA). To reconstruct the occluded area of broiler chickens, the linear restoration method and the elliptical fitting restoration method were developed and tested. Three evaluation indices of the overlap rate (OR), false-positive rate (FPR), and false-negative rate (FNR) were used to evaluate the restoration method. From images collected on d2, d9, d16, and d23, about 100-sample images were selected for testing the proposed method. And then, around 80 high-quality broiler areas detected were further evaluated for occlusion restoration. According to the results, the average value of OR, FPR, and FNR for TA was 0.8150, 0.0032, and 0.1850, respectively. For OA, the average values of OR, FPR, and FNR were 0.8788, 0.2227, and 0.1212, respectively. The study provides a new method for restoring occluded chicken areas that can hamper the success of vision-based machine predictions.

Background and Aim: Newcastle disease virus (NDV) remains a major viral disease of poultry. The morbidity and mortality rates of chickens vaccinated with NDV in broiler farms in Diyala Province were 100% and 80%, respectively, rates due to suspected infection with the highly virulent NDV. The present study aimed to isolate and identify the NDV virus and evaluate its pathogenicity in infected broiler chickens at poultry farms. Materials and Methods: Broiler chickens at two commercial poultry farms were suspected of being infected with virulent NDV due to high mortality rates. Virus isolated from samples of intestinal tissues, lungs, trachea, spleen, kidneys, and air sacs was adapted in the allantoic cavity of embryonated specific-pathogen-free (SPF) chicken eggs. The NDV pathotype was determined based on the mean death time (MDT) in eggs as well as the intracerebral pathogenicity index (ICPI) and intravenous pathogenicity index pathogenicity indexes of the isolated samples. Broilers were experimentally infected by inoculation with fluids collected from the allantoic cavities of 60 broilers aged 35 days. Serological and molecular tests were followed by enzyme-linked immunosorbent assay to determine levels of anti-NDV immunoglobulin G, and isolates were identified using a hyperimmune (HI) test and real-time polymerase chain reaction (RT-PCR). Results: Suspected and isolated NDV field samples propagated in the allantoic cavity of 10-day-old fertile SPF chickens were NDV positive in the rapid hemagglutination test within a few seconds. Pathogenicity indices and MDT showed that the isolated NDV was viscerotropic and velogenic. The virus was identified as NDV by the HI test using specific anti-LaSota HI serum and RT-PCR with specific primers and probes. Propagation of the virus in the allantoic cavity of embryonated hen eggs produced a viral titer of 109.5 EID50/0.1 mL. Conclusion: The virus isolated from broiler chicken farms in Diyala Province, Iraq, was viscerotropic and velogenic according to the pathogenicity indices and RT-PCR. The isolated NDV caused 100% morbidity and 90% mortality in NDV-vaccinated and experimentally infected broiler chickens.

Abstract. Strategies for quantifying heat loss of broilers on live-haul trailers would be beneficial, particularly under conditions of environmental extremes. We have developed an electronic chicken (a self-contained, temperature-controlled heat source) to simulate the sensible heat loss of a live broiler during the transit and holding periods in commercial live-haul trips. The simulated electronic chicken is an aluminum box, having surface area equivalent to a 2.3 to 2.8 kg broiler chicken (0.13 m2), with a thermostatically controlled power source to maintain the internal temperature at 41°C (typical broiler core body temperature). Different cover materials were tested to identify an appropriate cover that resulted in measured values of electronic chicken heat production being similar to published values of sensible heat production for broilers. A double layer of fleece fabric provided a reasonable match. The sensible heat loss of the electronic chickens exhibited positive correlation with exposed wind, and a positive correlation with temperature gradient between internal and external environment. Wetting the fabric cover of electronic chickens only slightly increased heat loss as compared to the dry fabric cover. Wet fabric cover experienced lower heat loss than that expected from the wetted surface of a live chicken, therefore heat loss under the wet scenario would be underestimated. Electronic chickens were installed in modules on trailers with live chickens during commercial live-haul process under various environmental conditions and different management practices. Measured heat losses from electronic chickens were in the range of 8.2 to 20.3 W with outside temperature of -17°C to 3.0°C in winter, and 4.5 to 6.7 W with 28°C to 34°C in summer. Based on literature-reported sensible heat loss under thermoneutrality, it was determined that the measured air temperature inside the live-haul modules on the trailer in the range of 11°C to 25.1°C during transit (outdoor temperature range of 1.7°C to 22.2°C) and 5.3°C to 21.7°C during holding (outdoor temperature range of -9.1°C to 19.8°C) would allow the live chickens to regulate heat by their metabolism and stay comfortable. For the holding period, the winter trips were mostly in the zone of thermal comfort. In summers, hyperthermic conditions were possible during transit, although additional cooling due to surface wetting of birds as a result of misting (on the farm prior to beginning the transit) could have been beneficial but not detectable by electronic chickens. The electronic chickens can be used effectively as a model to evaluate and identify conditions that cause thermal stress conditions during live-haul conditions and to design systems and strategies to alleviate that stress.

Background: Broiler chicken production is influenced by several factors, namely genetic, management, and environmental factors. Genetically superior chickens will not produce maximum results if not supported by a comfortable environment for chickens (comfort zone) because they are animals that will grow optimally at a certain temperature range. in addition, humidity also affects the production and health of chickens. So that the selection of the cage becomes important to create comfortable environmental conditions for chickens. Cage with a relatively stable temperature will greatly affect the production results, including body weight and feed conversion. Purpose: To determine the effect of temperature and humidity of semi-enclosed cages on weight gain and feed conversion of broiler chicken. Method: Observation was carried out during a period of maintenance of broiler chickens on farms and data collected in the form of the recording of chicken weight and feed conversion. Result: Temperature and humidity of semi-enclosed cages have a good effect on production results, with chicken harvest weight of 2197.3 grams and feed conversion of 1.52 kg. Conclusion: this study indicate that temperature and humidity have a good influence on weight gain of chickens and feed conversion value.

This research was about broiler chicken business in PD Pasar Jaya, Pasar Minggu, Jakarta Selatan by focussed on its market margin. The research objective was to identify marketing channels for broiler chicken, analyze the marketing margins of broiler retailers, and providing recommendation for broiler marketing channel management. The analysis method used was descriptive, marketing marjin, and marketing efficiency. There were four patterns of marketing channels and five marketing agencies. The most efficient marketing channel for broiler chickens was Channel 1 in the domestic chickens. Farmers distribute it directly to the retailers. Channel 1 had the lowest marketing marjin of IDR 16,000. The highest farmer's share value was 78%, meaning that the farmers received 78% of the price paid by the consumer. Marketing cost in the channel 1 was the smallest amounting to Rp 943. Marketing channel was efficient if the value was less than 5%, therefore channel 1 was the most efficient due to the value is the lowest at 1%. Chicken price fluctuations influenced by supply-demand which was subject to particular moments. An effective management recommendation define an effective and efficient marketing channel to set margins on the raw product so that the fair distribution of the margins between marketing channels. The fluctuation of chicken prices in breeders can be overcome by determining the period of raising chickens according to the demand data during particular moment.

Full textAbstract:
This study was conducted to determine the growth performance and profitability of broilers chicken with vermi meal supplementation under a total confinement management system. A total of 60 broiler chickens were randomly distributed to four dietary treatments: T1= commercial feed (CF), T2= CF+2% vermi meal (VM), T3= CF+3% VM, T4= CF+5% VM inclusion in a completely randomized design. Feed conversion ratio was not significantly influenced by VM supplementation. However, the highest feed intake was recorded in broilers fed CF supplemented with 2% VM (T2) while control broilers fed only CF (T1) had the lowest feed consumption. Broiler chickens fed CF supplemented with 2% VM (T2) were recorded with the highest values of final body weight and weight gain compared to T1 group and T4 group, respectively. However, broiler in T2 group had similar values of body weights and weight gains compared to T3. Consequently, 2% level of VM had an optimum result in final weight, weight gain, and feed consumption, while comparable to the other treatments in water consumption, feed conversion ratio, dressing percentage, and carcass weight. Cost and return analysis of the dietary treatments with VM showed a negative effect, since the higher concentration of VM supplementation had the higher cost in production, due to the expensive price of imported vermin or earthworm meal.

AbstractThe activity of selenium-dependent glutathione peroxidase (GPX), liver concentration of vitamin E, and plasma and liver selenium levels were used for estimation of the antioxidant status of broiler chickens infected with Ascaridia galli. These biomarkers were recorded in an experiment covering 70 days p.i. At the same time the establishment rate of A. galli in chicken intestines, gain in the host body weight and chicken survival were studied. Broiler chickens (Cobb hybrids) were infected with 1450 embryonated A. galli eggs and treated with Sel-plex. A mathematical model was applied to determine the rate of nematode reduction and the relative rate of gain of host body weight, which are essential kinetic parameters of parasite–host interaction. The activity of GPX increased with both elevated selenium and reduced infection levels. The concentrations of selenium and vitamin E, and the GPX activity in the infected chickens demonstrated a similar pattern of change with time after day 30 p.i. The supplementation of the broilers with dietary selenium in the form of Sel-plex improved their antioxidant status. Increases by 29% in vitamin E concentration, 15% in GPX activity, and 22% in liver selenium concentration, respectively, were recorded in the infected and treated, compared to infected and untreated broilers.

AbstractProhibition of application of antibiotic growth promoters in broiler chicken diets has resulted in increased use of herbs as natural additives in broiler feeds over the recent years. Researchers particularly look for herbs that can affect such parameters as growth performance, immune response, or treatment of certain diseases. Aloe vera is a well-known herb characterized by properties such as anti-bacterial, anti-viral, anti-fungal, anti-tumor, anti-inflammatory, immunomodulatory, wound-healing, anti-oxidant, and anti-diabetic effects. During the past years, attention has shifted toward Aloe vera as a natural additive to broiler diets, and studies have shown that Aloe vera can improve immune response and growth performance in broilers. In addition, Aloe vera is an excellent alternative for antibiotic growth promoters and anticoccidial drugs. Since Aloe vera can be used for broilers in the form of gel, powder, ethanolic extract, aqueous extract, and a polysaccharide contained in Aloe vera gel (i.e. acemannan), more studies are required to determine the best form and to compare Aloe vera with other medicinal herbs. This paper reviews effects of Aloe vera on intestinal microflora, growth performance, immune response, and coccidiosis in broiler chickens.

The research was aimed to determine the volume and time of giving the natural antibiotic which are optimal for the value of Index Performance (IP) of broiler chickens. The first treatment variable was: giving natural antibiotics with a dose for partition 1 0.05mL / 40 mL water / chicken / day, partition 2 0.1mL / 40 mL water / chicken / day, partition 3 0.15mL / 40 mL water / chicken / day, partition 4 (synthetic antibiotics as a comparison) and carried out for 35 days in a fixed time of 24 hours. Optimal results with the best Index Performance (IP) obtained from the first variable followed by the second treatment variable, the time of giving natural antibiotics for partition 1 given once a day, partition 2 every two days, and partition 3 three days with a constant giving dose 0.15 mL / 40 mL water / chicken / day for 35 days. The parameters observed were: (1) average body weight, (2) weight gain, (3) feed consumption, (4) feed conversion, and (5) number of live chickens. From these data the IP of broiler chickens was calculated and from the two variables obtained the optimal dose and time of giving natural antibiotics. Based on research results from the product, the best of giving natural antibiotic volume is 0.15 mL / chicken or equal to 4.2 mL / 28 chickens which it is able to increase the value of broiler chicken IP until harvest time. From the optimal results obtained in the trial volume variation of giving natural antibiotic, the experiment can be continued with the aim of determining the optimal time of giving herbal antibiotics namely the best results are obtained once a day for 28 chickens because it shows that the giving natural antibiotic is able to increase the IP value of broiler chickens until harvest.

The study included the determination of the meat productivity of broiler chickens when the antioxidant emidonol was added to the diet. For the experiment, 3 groups of day-old chickens were formed, 2 groups were given emidonol. The addition of an antioxidant to the diet of broiler chickens did not cause a change in the physiological status of the chickens. Sorting of chicken carcasses taking into account fatness showed that the best quantitative characteristics were carcasses from chickens treated with emidonol from the daily age at a dose of 2.0 mg/head for 14 days. According to the results of the use of emidonol in the diet of broiler chickens, it was revealed that the drug did not affect the physiological status of the bird and positively affected the formation of the meat qualities of the chicken carcass.

Full textAbstract:
Changing patterns of human resource use and food consumption have profoundly impacted the Earth's biosphere. Until now, no individual taxa have been suggested as distinct and characteristic new morphospecies representing this change. Here we show that the domestic broiler chicken is one such potential marker. Human-directed changes in breeding, diet and farming practices demonstrate at least a doubling in body size from the late medieval period to the present in domesticated chickens, and an up to fivefold increase in body mass since the mid-twentieth century. Moreover, the skeletal morphology, pathology, bone geochemistry and genetics of modern broilers are demonstrably different to those of their ancestors. Physical and numerical changes to chickens in the second half of the twentieth century, i.e. during the putative Anthropocene Epoch, have been the most dramatic, with large increases in individual bird growth rate and population sizes. Broiler chickens, now unable to survive without human intervention, have a combined mass exceeding that of all other birds on Earth; this novel morphotype symbolizes the unprecedented human reconfiguration of the Earth's biosphere.

Salmonella enterica subsp. enterica serotype Infantis isolates from retail raw chicken meat (n = 98) and broiler chickens on farms (n = 70) were examined for antimicrobial susceptibility and antimicrobial resistance genes. A total of 15 antimicrobial resistance types, 14 in meat and 10 in broiler isolates, were identified, and 9 of the 15 types were indistinguishable between meat and broiler isolates. Resistance to both oxytetracycline and dihydrostreptomycin accounted for 94.0% of the resistance types in meat and broiler isolates, and each type harbored aadA1 within 1.0 kb of class 1 integron and tetA. Of nalidixic acid resistance types, point mutations at 87Asp (GAC) to Tyr (TAC) in the quinolone resistance-determining region of gyrA was detected in 10 of 13 meat isolates and at 87Asp to Asn (AAC) in four of seven broiler isolates. These findings suggest that the antimicrobial resistance of Salmonella Infantis in retail chicken meat predominantly originates from broiler chickens.

This research was conducted to observe the body weight gain and carcass quality of the hybrid chicken derived from the crossing between female F1 Kampung Super and male F1 Kampung-Broiler. The weekly weight gain for seven weeks and carcass quality, including breast yield, protein content, lipid content, moisture, and pH were measured with each group consists of six individuals. The chickens were slaughtered for meat quality measurements on the 7th week. The results showed that the hybrid chickens’ weight at the 7th week (888.22±139.63) was higher than layer (467.06±85.7) and pelung (436.39±42.33). The hybrid chicken’s breast yield (3.20%) was significantly higher than pelung’s (1.66%). These characteristics of hybrid chicken breast muscle lead to the conclusion that hybrid chicken is a potential alternative meat-type chicken with local chicken meat characteristics and has relatively fast growth.
