The objective of this study was to verify the possibility of replacing soybean oil in a diet with glycerol, and investigate the effect of glycerol on performance indicators and health in broiler chickens. The experiment was performed on 122 one-day-old chickens that were divided based on sex into two control groups (30 females and 31 males) and two experimental groups (30 females and 31 males). Half (50%) of the soybean oil in diets used in the experimental groups was replaced with glycerol at a ratio of 1:2. On 15, 32 and 38 day of age chickens of both sexes in the experimental group that were fed with diets containing glycerol showed significantly higher (p ≤ 0.01) mean body weight compared to the control group. At the end of the experiment, the mean weight of chickens in the control group was 2.078 kg, whereas the mean weight of chickens in the experimental group was 2.341 kg. In females, the overall consumption of diets within 38 days of fattening was 3.588 kg in the control group and 4.011 kg in the experimental group, in males, it was 3.915 kg in the control group and 4.366 kg in the experimental group, i.e. it was higher in experimental chickens. Feed conversion in chickens in experimental groups was better, being 1.84 kg in the control group and 1.81 kg in the experimental group in females, and 1.73 kg in the control group and 1.72 kg in the experimental group in males. It follows from our results that the optimum amount of glycerol in feed for poultry is 5%.This study presents an original solution to optimize feed formula by replacing plant oil with glycerol. The results of the study can improve production indicators and economy in broiler fattening.

The main task in meat poultry production is to obtain products in a short period of fattening with the minimum feed costs. In economic terms, fodders occupy the largest share in the cost structure of poultry meat. The feed in its composition and properties should satisfy the physiological needs of the chicken, as much as possible, and this, in turn, directly depends on its usefulness and quality. In this regard, the actual issue of feeding is the use of antioxidants to improve the conservation of feed and optimize metabolism in the body of the bird. The inclusion of “Bisfenol-5” antioxidant in full-feed mixed doses in doses of 0.002-0.015% of the feed weight positively affected the growth rate of broiler chickens and feed conversion. The highest effect was obtained with the addition of “Bisfenol-5” in the amount of 0.008% to the compound feed. The use of antioxidant-enriched mixed fodder for growing chicken broilers allowed to increase meat production to 17.5%, to increase feed conversion to 12.1%, to reduce the cost of 1 kg of live weight gain to 6.99 rubles and to improve the efficiency index to 0.2 points.

I consider it important that the fattening of broiler producers in an economic sense to remain alive in the present difficult situation. This does not mean to me, that just does not generate a loss, but they do remain in their activities after income. Because if you do not have sufficient income in a given sector then the technology becomes obsolete over time and income deficit due to the possible improvements are still lagging behind, resulting in competitive disadvantages occur. The natural efficiency remains a priority, because fundamentally determine our competitiveness in the broiler production. In the present study, scenario analysis can prove the veracity of my claim, in point of the three most important natural efficiency indicators. The natural efficiency indicators of a company compared to the natural effectiveness of our country and the our competitions (Western-European countries).

It is assumed that the combined effect of an effective probiotic and feed bentonites will enhance their positive effect on the growth, development, immunity of poultry, the quality of products, economic results of production. The purpose of the research was to study the effectiveness of the probiotic Vetkor and trace elements contained in bentonites in the compound feed of broiler chickens. Scientific and economic experiment has been carried out in the company “Uksyansky broiler” on broiler chickens cross “Smena-4”, which have been distributed in 3 groups on the principle of analogues. For each group 50 heads have been selected one day-old chickens. The conditions for rearing and housing the chickens were the same. The joint use of bentonite and probiotic in rearing and fattening broiler chickens have been studied. At the beginning of rearing the weight of chickens in all groups was almost the same and averaged 39,6 g. However, with increasing age of chickens not only their live weight increased, but also the difference between groups for this indicator. So, at the age of 7 days the chickens of the 1st experimental group had live weight higher than the control ones by 1,86 %, and the chickens of the 2nd experimental group by 2,00 %. The live weight of the broiler chickens of the control group at the end of rearing (age 42 days) was less than the live weight of the 1st broiler chickens of the experimental group by 101,14 g or 5,23 % (P < 0,05), and the 2nd experimental group by 132,14 g or 6,83 % (P < 0,01). The total and average daily increase in live weight of chickens of the 1st experimental group was greater by 5,34 % (P < 0,05), and the 2nd experimental group by 6,96 % (P < 0,05) than in the control group. Broiler chickens that consumed the probiotic Vetkor in the compound feed had higher growth energy than in the control. Against this background the best growth has been observed in broiler chickens of the 2nd experimental group who consumed compound feed with the addition of Vetkor and 3 % bentonite. It has been experimentally justified the use of probiotic and bentonite in the industrial production of meat of broiler chickens, it has been established a positive effect of probiotics and bentonite on the growth and development of broiler chickens, the quality of the resulting products.

The aim of this paper was to determine how forage triticale in diets for fattening broilers influence the body weight and weight gain of broiler chickens for fattening. The survey was conducted on 400 chickens for fattening provenance Ross 308 for a period of 42 days. On this occasion, four groups of chickens were formed, with 100 chickens being treated in each group, as follows: K (classic mixture for fattening broilers) and O-I (mixtures with triticale variety Kg 20), O-II (mixtures with triticale Favorit) and O-III group (mixtures with triticale Trijumf). The highest average body mass in the groups of chickens (male, female and chicks of both sexes), was scored by broiler chickens of O-II-group. The minimum food consumption for 42-day-old chicks was achieved by group O-I (4.275 kg), and the most by O-II group (4.359 kg). Chickens of O-II- and III-O-group had the best feed conversion, while the chickens of O-I-group had a slightly poorer feed conversion. The mortality of the groups of chickens for the entire period of the study was the lowest in O-II-group, at 2.0%, and the highest mortality was found in O-III-group (6.0%). The production index was the highest in O-II-group (202.726) and the lowest in O-I-group. The results achieved in this research indicate that the use of tested triticale cultivars significantly affected the weight gain and body mass of chicks and have nutritional and economic justification.

The purpose of the research was to determine the feasibility and effectiveness of using a natural antioxidant of plant origin – dihydroquercetin (DHA), as a biologically active substance, in combination with the main standard diet of broiler chickens. Scientific and economic experience conducted in production conditions on broiler chickens of the "COBB-500" cross allowed us to objectively establish that the addition of the biologically active substance Dihydroquercetin to mixed feed contributes to the increase in meat productivity and safety of broiler chickens. Feeding of broiler chickens was carried out with full-fledged compound feeds, in accordance with the recommendations of the originator for this cross. In terms of energy nutrition and the content of nutrient active substances, they were the same and differed between the groups in the amount of the additive administered. Chickens of the 1st control group received only feed (basic diet), the 2nd experimental group – advanced antioxidant supplement Dihydroquercetin in the amount of 0.5 g per 100 g of feed, the 3rd – 0.75 g per 100 g of feed, and 4th – 1 g per 100 g of feed. The duration of the experiment was 40 days and to clarify the effectiveness of increasing the duration of the broiler fattening period, it was extended to 60 days. Broiler chickens were reared on the floor, temperature and light conditions, air humidity, feeding and watering front of the bird during the experiment corresponded to the recommended standards. As a result of the conducted studies on the effect of adding optimal levels of biologically active feed additive Dihydroquercetin to the diet of broiler chickens, it was found that during the growing period, a higher coefficient of live weight gain was established in broiler chickens of the 3rd and 4th experimental groups, whose live weight increased by 105.32 and 120.48 times by the age of 40 days, while in broiler chickens of the 2nd experimental group by 102.57 times and the lowest–in control group chickens only in 90.96 times. The selected feed additive can be considered as an alternative to the use of feed antibiotics in the feeding of broiler chickens in industrial poultry farming technology.

Bearing in mind certain established European Union regulations on the conventional extensive broiler rearing system as well as poultry breeding specificities of our country, experimental investigations were organized with the aim of making a comparison between broiler growth in two different non-industrial rearing systems. The systems included extensive fattening in a poultry house and free-range rearing. The fattening period in both rearing systems lasted up to the 63rd day of broiler age. During the fattening period chicken growth was controlled by individual chicken weighing on a weekly basis. Based on the research results it was determined that the growth of broilers in both rearing systems was similar up to the 49th day of age. The differences established were small and statistically insignificant (P>0.05). The controls at 56 and 63 days of age showed somewhat higher differences in mean body weights of chicks. The difference determined on the 63rd day was statistically significant (P<0.05). From the results mentioned it could be concluded that the differences in broiler growth between the rearing systems examined increased with the prolongation of the fattening period.

In industrial poultry production, especially in broiler chickens, coccidiosis, caused by Eimeria protozoa parasites in the digestive tract, continues to be a serious health and economic problem. In economic terms, the losses are mainly caused by the costs of prevention and treatment, as well as the reduced weight gain and reduced condition of the birds. Currently, the prophylactic program of this disease unit is mainly based on the use of chemotherapeutics. Another way to control coccidiosis is active immunoprophylaxis, based on the vaccination of chickens for fattening, and passive immunoprophylaxis, based on vaccination of the parent flock. An alternative, effective way to reduce the negative effects of protozoan infestation by Eimeria may be the use of herbs and their extracts, pre- and probiotics and betaine.

Slow growing chickens of genotype Redbro, were reared in two systems in order to determine the effect of duration of fattening on values of slaughter yields/dressing percentages and shares of main carcass parts. Fattening of chickens in chicken coop to age of 84 days had considerable effect on increase of slaughter yields: "Conventional processing"(83.59%), "Ready to roast"(77.22%) and "Ready to grill"(67.17%) compared to 42nd day of age (82.21; 74.87 and 65.42%). Redbro chickens reared on free range had lower body masses compared to chickens reared from chicken coops in all investigated ages. Beside significant increase of body mass, longer fattening period influenced considerably decrease of share of back, pelvic and wings. In both rearing systems, prolonging of fattening had statistically significant effect on increase of share of abdominal fat. .

Die Wasserproduktivität in der Tierhaltung ist von vielen Faktoren abhängig. Die Futterproduktion hat den größten Anteil am Wasserbedarf von tierischen Produkten. Weitere Einflussfaktoren sind die Leistung, die Reproduktion und der Gesundheitsstatus der Tiere, das Management und die Haltungsbedingungen. In dieser Arbeit sollte untersucht werden, wie sich diese Faktoren auf die Wasserproduktivität von Milch und Geflügelfleisch in Nord-Ost-Deutschland auswirken. Zehn unterschiedliche Futtermittel wurden hinsichtlich ihres Wasserbedarfes untersucht. Aus diesen Futtermitteln wurden die Rationen für die Tiere erstellt. Die Milchleistung der Kühe wurde zwischen 4.000 und 12.000 kg Milch pro Kuh und Jahr in 2.000 kg Schritten variiert. Für jedes Leistungsniveau wurden zwölf verschiedene Fütterungsstrategien untersucht, welche auf der Erhöhung einzelner Bestandteile der Ration basieren. Der Wasserbedarf von Leitungswasser im Stall wurde mit 38 Wasserzählern ermittelt. Für die Wasserproduktivität des Geflügelfleisches wurden vier verschieden intensive Mastverfahren untersucht. Die Wasserproduktivität steigt mit steigender Milchleistung der Kühe. Das Maximum wird bei 10.000 kg Milch pro Kuh und Jahr und Rationen mit einem hohem Gras- bzw. Maissilageanteil erreicht. Die Kühe, die im automatischen Melksystem gemolken wurden, nahmen mehr Tränkwasser zu sich, als die Kühe im Fischgrätenmelkstand. Dies ist durch die höhere Milchleistung bedingt. Im automatischen Melksystem wurden im Mittel 28,6 Liter Reinigungswasser pro Kuh und Tag benötigt. Für die Reinigung des Fischgrätenmelkstandes wurden 33,8 Liter pro Kuh und Tag genutzt. Die untersuchten Broilermastverfahren zeigten keine Unterschiede hinsichtlich der Wasserproduktivität. Die intensivere Aufzucht und bessere Futterverwertung wurde durch eine niedrigere Wasserproduktivität des Futters kompensiert. Der Anteil des technischen Wassers macht in der Milchkuh- und Broilerhaltung nur einen kleinen Teil am Gesamtwasserbedarf aus.
Livestock production is the main user of water resources in agricultural production. Water is used in animal production for producing feed, watering the animals, and cleaning and disinfecting barns and equipment. The objective of this dissertation was to quantify the effects of management strategies, such as feeding, intensity of production and the replacement process on the water productivity of milk and poultry meat in Germany. Water productivity in milk and broiler production systems was calculated based on the methodology of Prochnow et al. (2012). Own measurements of the drinking and cleaning water demand in milk production were conducted in a dairy cow barn. The study was based on site conditions of North-East Germany with common variations in farm operations. The feed production is the main contributor to water input in dairy and poultry production. The water productivity of milk increased with an increasing milk yield. The most beneficial conditions related to water productivity in dairy farming were found to be with a milk yield of approximately 10,000 kg fat corrected milk and a grass silage and maize silage based feeding. The total technical water use in the barn makes only a minor contribution to water use. Former regression functions of the drinking water intake of the cows were reviewed and a new regression function based on the ambient temperature and the milk yield was developed. In broiler production the intensification of the fattening systems did not increase water productivity. An increase of water productivity in animal production can be achieved with various management strategies with their specific influence on the production process. The feed management should be a focus of the strategies.

The influence of biological supplement AEN 700 in broiler chicken fattening was traced in operating conditions of broiler houses Kladruby.This influence was analysed economically.Compared to year 2005 when the antibiotic stimulators of growth were used there are well-balanced zootechnical and economical results.The results of development confirmed that the biological supplement AEN 700 has minimally equivalent effect in production and in economical effect compared to antibiotic stimulators of growth.

The present case study deals with new pathways in demand for forest residues disposal in the Lafões region (Portugal), since this biomass is presently regarded as a residue and eliminated through open air burning. Different biomass-to-energy conversion systems have a high sustainability value and, thus, the energy potential of the biomass supplied by the forest of Lafões was assessed, using GIS-based methods and assumptions from the literature. The Lafões region produces large amounts of chicken manure from which energy can be recovered through anaerobic digestion. The energy potential held by the effluent of the several classes of the poultry industry of Lafões was assessed, using IPCC 2006 guidelines to estimate their biomass and methane production potential. Furthermore, integrated solutions were pursued. The present challenge is to explore complementarities between effluents for anaerobic digestion to achieve improved energy and waste management system performances. The complementarity between the residues from maritime pine forest management and from broiler production was assessed through bench-scale anaerobic co-digestion assays, leading to increased methane production when compared to those achieved with single substrate anaerobic digestion. This result highlights the interest of further research concerning complementarities between other effluents in the Lafões region.
