Abstract:

A study was conducted to evaluate local duck production systems in Imo and Abia States of Nigeria. Seventy-two (72) local duck farmers from both States were purposefully selected using snowball sampling techniques and were interviewed using structured questionnaires.Data on farmers' socio-economic characteristics and production practices were collectedand analyzed using descriptive statistics such as frequencies, percentages and charts. Theresults showed that there were more male duck farmers (88.89%), while the average age of duck farmers was 51.35years. Most (97.22%) of the duck farmers were literate, 58.33% ofhouseholds had between 4 - 7 members, 73.61% of duck farmers were Christians and a higher number (46.43%) raised pigs alongside of ducks. Most farmers (98.61%) kept only Muscovy ducks. The average flock size is about 6-9 ducks per household. Ducks were mainly kept for rituals and traditional medicine (56.78%). About 48.61% of farmers used personal money to finance duck farming, while 47.22% of farmers inherited their foundations stock. The age at sexual maturity for ducks was 7 to 9 months; clutch length was 11 to 15 days, while clutch size ranged from 16 to 20 eggs. Again, 94.44% of farmers practiced extensive system of duck keeping while 84.72% did not provide supplementary feeds to their ducks. Accidents are the leading cause of mortality in ducks, while the myths that surround ducks are the main obstacle to duck meat consumption. The results showed that duck farming is not popular in the study area and therefore, ducks are seen and kept as sacrificial birds. Thus, the potential of ducks for the production of meat and eggs is not fully exploited. These myths that have hindered the production of ducks could be dispelled through farmer trainings and enlightenment.

Abstract:

Duck is one of the commodities that contribute to the national livestock production and Central Java is home to the fourth biggest duck population after West Java, South Sulawesi and East Java. The 2019 egg production in Central Java was 36.174 tons or 11.3% of the total egg production nationwide. Accordingly, it is important to investigate the effect of environmental factor, total number and age of ducks on egg production in Central Java. Specifically, this study aimed to observe the effect of region on egg production and feed conversion ratio (FCR) and the total livestock (chicken), age (month), stocking density (ducks/m2), internal housing temperature (oC), and humidity (%) on Hen day production/HDP. A survey engaging purposive random sampling was conducted on the population of duck farming in Central Java especially Tegal, Pemalang and Brebes districts. The data were subjected to General Linear Model (GLM) and a regression-correlation analysis using an SPSS program. The result showed that region significantly affected hen day production (HDP) but did not affect FCR. Housing temperature affected HDP by 14.9% and the higher the temperature, the lower the HDP. Duck age affected HDP by 11.7%, and the older the ducks the lower the egg production. Duck population, stocking density and humidity did not significantly affect egg production. Conclusively, duck egg production (HDP) is significantly affected by temperature inside the housing and the duck age.

Abstract:

Muscovy duck is a type of waterfowl that has a relatively better growth and percentage compared to ducks. Duck meat has high-quality because of its low fat and savory flavor. Muscovy duck is relatively resistant to the disease and is able to use low-quality feed, but has the disadvantage of low egg production. The development of Muscovy duck as a producer of meat can be done through two approaches, namely the long-term and short-term. The long-term approach is carried out by selecting Muscovy duck which has high growth rate and high meet quality. The selection can be done in two ways, namely directly on the nature of growth and the quality of meat, and indirectly by choosing a marker of growth (morphology, biochemistry or diversity of DNA/ RNA). Short-term selection can be done by bringing in superior Muscovy duck from the outside to be developed by farmers and crossing male Muscovy duck with the layer Indian Runner ducks to produce Serati ducks.

Abstract:

Abstract The need to complement the supply of animal products with other sources of poultry necessitates exploring the potentials of domestic duck production. Studies conducted on indigenous ducks in Nigeria have paid less attention to the resource requirements and its determinants to duck production. This study therefore estimated technical efficiencies of domestic duck producers in South-western Nigeria, and identified some socio-economic factors, which influence them. A combination of purposive and random sampling was employed. Stochastic frontier production function approach using a translog production function was used to estimate the technical efficiencies of indigenous duck producers, while inefficiency model was used to determine the socio-economic factors affecting the technical efficiencies. The results showed that the level of technical efficiency ranged from 48% to 96% with a mean of 83.3%, which suggests that average duck output was 16.7% short of the maximum possible level. This implies that productive efficiency could still be improved using the subsisting resource base. The study concluded that mounting capacity building programmes for duck farmers generally, and availability of credit could increase the productivity of duck enterprise if monitored.

Abstract:

The present study was conducted to know the morphology, morphometry, production and reproduction potentialities of Nageswari duck, an indigenous duck genetic resource of Bangladesh. Data on 58 representative adult Nageswari ducks were included for morphological study from 24 duck owners and two government organizations having Nageswari duck flocks while 468 individuals were considered for the traits of productive and reproductive performances. Information was collected by using a structured questionnaire through personal interaction, on spot recording and direct phenotypic measurements in five different regions of Bangladesh. Black plumage color with white stripe extended from neck to breast make unique features of Nageswari duck compared to other indigenous ducks. Morphometric measurements on adult live weight, body length, head diameter, bill length, neck length, shank length, wing length, massiveness and condition index in male and female were found to be 1.66±0.07 and 1.51±0.05 kg, 26.27±0.57 and 23.79±0.39 cm, 3.49±0.02 and 3.36±0.04 cm, 5.87±0.09 and 5.54±0.07 cm, 23.49±0.58 and 21.59±0.49 cm, 5.76±0.12 and 5.16±0.11 cm, 24.58±0.49 and 21.99±0.53 cm, 6.33±0.28 and 6.39±0.22, and 6.72±0.23 and 6.93±0.23 respectively. Age at first egg of Nageswari duck was found to be 168.48±3.53 days. Total number of eggs laid per year averaged 173.63±3.39 and peak production was found in 29.46±0.19 weeks. The average egg weight was estimated to be 67.32±0.82 g and characteristic bluish tinge of egg color was observed. Breed specific characteristic features and production profiles were observed in this study. The present study provided some baseline information on Nageswari duck of Bangladesh which could be useful for genetic characterization, conservation and future improvement programs in Bangladesh.Bang.

Abstract:

Broiler ducks are ducks that are able to grow fast and can efficiently convert feed into meat with high nutritional value. Broiler ducks have good flesh structure and structure. The good meat structure of broilers is now becoming more popular among the people, because the taste of the meat is tasty and tasty. Broiler ducks known by the public include hybrid ducks and Peking ducks. The ever-increasing need for duck meat is not matched by the availability of enough duck meat in the market, to meet the needs of the community. This could be the potential to cultivate broilers as evidence that poultry business and agribusiness, especially ducks are still wide open with promising profit prospects. The method used is: to maintain broilers totaling 50, each of which consists of 25 hybrid ducks and peking 25 tails, then feeding and drinking, taking data through recording weighing weight, and analyzing the profitability of broiler duck farming. Based on maintenance for 42 days, the data obtained was the consumption of 3.645 g / tail hybrid rations and the consumption of 3.727g pork duck / tail, United Nations hybrid duck 1.168,8 g and peking duck 1.171,04 g, FCR hybrid duck 3.11 and Peking duck 3.18 and hybrid duck mortality 4% and Peking 12%. Weight gain, mortality, and conversion of Peking duck feed were higher than hybrid ducks.Â Keywords: hybrid duck, Peking duck, Production PerformÂ

Problem. On the present time both Lithuania and EU market dominate pigs and cattle breeding. Consumer researches shows, that growing demand on high digestibility and nutrient, quick prepare animal products. On this way duck meat is very valuable product. Problem is that now dominate small farms, where traditionally growing few local, not very productive ducks. Like there is no real local market, so there is no well develop duck breeding. The subject of research. After good analyses of duck breeding and risk factors, to take measures of duck business development in Lithuania. Tasks: To estimate different duck species peculiarity and analyse duck meat quality depend to market demand; To estimate duck breeding technology and use in Lithuania farms; To estimate risk and possibility of duck business in Lithuania. Results. Consumer researches shows, that people prefer not fat, fragile, muscular duck meat. These features satisfy meat duck mularde females. From a technological viewpoint duck is insensitive to temperature, moisture, feed changes, so it’s possible to grow them both intensive and extensive farms. Technological, zoohigienic and economic duck growing research showed that the most promising duck breeding is like part business – on the summer time use empty animal husbandry buildings. At best is to grow heterozic hybrids. These precondition enable in Lithuania to create small duck farms, which sells fresh meat straight from the farm and secure flexible sells and... [to full text]

Abstract:

Nest predation is a major factor impacting duck production and recruitment on breeding areas in North America. I surveyed waterfowl managers employed by the U.S. Fish and Wildlife Service and U.S. state wildlife agencies to determine their beliefs about nest predation and its management. Over 64% of respondents believed that rates of nest success on their management units averaged <30% between 1996-2000. Managers believed habitat management and direct predator control were the most effective techniques to reduce nest predation. The construction of predator exclosures around nesting habitat also has been recommended to reduce nest predation. Between 1999-2001, I evaluated the effectiveness of 4 predator exclosures to enhance duck nest success at Bear River Migratory Bird Refuge, Utah. During this period, rates of nest success in the exclosures were slightly higher than that within control plots, but still <15%. Although published guidelines commonly recommended predator fences ≤ 117 cm in height, I observed red foxes jump the 114-cm-high fences. Additional research is needed to identify effective predator fence designs. Wildlife managers have argued that periodic disturbance of vegetation should be a component of management on waterfowl breeding areas. Although many techniques are available to manipulate vegetation, grazing by domestic livestock has been controversial. Some researchers have reported that livestock grazing is detrimental to nesting ducks whereas others have argued that it can be beneficial. I evaluated the impact of a short-duration, high-intensity winter livestock grazing program on duck nesting at Bear River Migratory Bird Refuge. Following a winter grazing treatment, I measured visual obstruction on both grazed and ungrazed plots during the spring nesting season. Although visual obstruction readings on grazed plots were lower than those on rested sites early in the nesting season, those differences diminished as the season progressed. Winter grazing may impact early-nesting ducks like mallards (Anas platyrhynchos), but not late-nesting species like cinnamon teal (Anas cyanoptera) and gadwall (Anas strepera). In designing grazing programs to manage nesting cover, managers should consider their waterfowl production goals, the composition of breeding duck populations, type of grazing system, and climatic conditions.

Dissertação do Mestrado em Engenharia Eletrotécnica e de Computadores - Ramo de Energias Renováveis e Sistemas de Potência
A redução das emissões de CO2 na atmosfera, requer apostas em soluções sustentáveis, sendo uma delas a integração de energias renováveis variáveis (ERV) na rede. A transição para sistemas em que existe forte penetração de ERV, exige o aumento de flexibilidade do sistema elétrico. Um dos requisitos para garantir essa flexibilidade, é o armazenamento de energia. O armazenamento de energia permite mitigar vários problemas na rede, entre eles, a duck curve. Foi realizado o estudo sobre o impacto do armazenamento no diagrama de carga da subestação São João, em Coimbra, na presença de geração fotovoltaica e eólica. Os resultados obtidos permitiram concluir que o armazenamento de energia, é um requisito necessário para que o sistema elétrico tenha flexibilidade, após a penetração da geração fotovoltaica distribuída. O armazenamento através da geração eólica na rede, pode auxiliar na redução da rampa do consumo durante o final do dia. Com este método, foi possível diminuir o efeito duck curve, através do peak shaving. A maioria da energia eólica armazenada foi durante o dia, em que existe consumo reduzido na rede, devido à massiva geração fotovoltaica. Quanto maior for a geração eólica, nos períodos de baixo consumo, maior é a necessidade do armazenamento.
The reduction of carbon pollutions requires betting on sustainable solutions, one of them is the integration of variable renewable energies (VRE) in the grid. The transition to systems where there is a higher penetration of VRE, requires increased power system flexibility. One of the requirements to ensure this flexibility is energy storage. Energy storage enables mitigate several problems on the grid, including the duck curve. The study of the impact of storage on the load diagram of the São João substation, in Coimbra, in the presence of photovoltaic and wind production was carried out. The results obtained allowed to conclude that the storage of energy, is a necessary requirement for the electrical system to have flexibility, after integration of distributed photovoltaic production. Wind production and storage system can help reduce the ramp consumption during the end of the day, where there is no photovoltaic production. It was possible to decrease the effect caused by duck curve, through peak shaving. Most of the wind energy stored was during the day, when the consumption in the grid is low, due massive photovoltaic production. Increased wind production requires increased storage capacity.

Abstract:

Baštenska jagoda (Fragaria x ananassa Duch.), poznata po svom delikatnom mirisu, ukusu i bogastvu u vitaminima i mineralima, gaji se u svim regionima sveta. Jagode, kao voće sa visokom proizvodnom i upotrebnom vrednošću, zahtevaju visoka ulaganja rada i metrijala po jedinici površine. Imajući ovo u vidu, jagoda zahteva posebnu pažnju u svim etapama proizvodnje (gajenja) tj. od zasnivanja jagodnjaka do berbe i prodaje. Cilj ovog istraživanja je, utvrđivanje investicione vrednosti zasnivanja i ostvarenih ekonomskih efekata koji se postižu u proizvodnji jagode karatkog i neutralnog dana u uslovima jugo-zapadnog Ontarija u Kanadi. Najveća proizvodnja u svetu se ostvaruje u severnoj hemisferi (90,5%). Vodeće zemlje po proizvodnji jagode su: SAD, Španija, Japan i Republika Koreja. Ove četiri zemlje čine 47,2% od ukupne svetske proizvodnje. Najveće povećanje kapaciteta jagode postignuto je u južnoj hemisferi. Za prikupljanje podataka o tehnologiji gajenja i investicionoj vrednosti ulaganja u proizvodnji jagode, korišćena je metoda anketiranja. U anketi je učestvovalo 19. proizvođača jagoda kratkog i 9. neutralnog dana u toku 2011. i 2012. godine. Upitnikom su prikupljeni podaci o tehnologije gajenja jagode po radnim operacijama, upotrebi materijala, mašina i radne snageTakođe, evidentirane su i strane usluge, ostvareni prosečni prinosi, prodajni kanali i procenat učešća u ukupnoj prodaji i postignuta prosečna cena.Na osnovu prikupljenih podataka izračunati su troškovi zasnivanja jagodnjaka, redovne nege i brbe u prvoj i drugoj godini i ostvareni profit za obe grupe jagode. Jagode kratkog dana se isključivo gaje u redovima na otvorenom, a jagode neutralnog dana na bankovima obloženim belom polietilenskom folijom i instaliranim kap-po-kap sistemom za navodnjavanje. Najveći procenat (70%) jagode kratkog dana se prodaje direktno kupcima na gazdinstvu ili lokalnim pijacama, a 55% jagode neutralnog dana se prodaje kanalima veleprodaje. U proseku, proizvođači jagode kratkog dana su postigli profit $CAD 22.300/ha (29,10% od ukupnog prihoda), a proizvođači jagode neutralnog dana $CAD 37.962/ha (29,50% od ukupnog prihoda).

Strawberry production, like many high-value crops, is resource and labour-intensive. Therefore, attention to detail is required at all stages of strawberry production, from establishment to harvest and marketing. The objective of this study was to determn the cost of strawberry establishment and achived economic effects of short-day and day-neutral strawberry production in south-western Ontario, Canada. The most of the production is located in the northern hemisphere (90.5%). The leading strawberry producing nations are USA, Spain, Japan and Republic of Korea. These four countries counted for 47.2% of all world’s strawberry production. The largest increase in strawberry production capacity was recorded in the southern hemisphere. For data collection on procedure for growing a crop of strawberries and investment in strawberry production a survey technique was used. In survey participated 19 short-day and 9 day-neutral strawberry growers and was conducted in 2011 and 2012. The survey recorded strawberry production procedures, materials, equipment and labour use. Also, growers reported externalMr Dragan M. Galić - Doktorska disertacijaviiservices used, achieved yields, marketing channels of sale, percent of each channel and achieved average sale prices. Based on collected information the cost of establishment, regular care, harvest in first and second year and total income were calculated for both groups of strawberries. Short-day strawberries are grown on matted-rows, while day-neutral on raised beds on white plastic with trickle irrigation installed. Most (70%) of the short-day crop was sold via direct sale (“U-pick”, ready-picked and farmers’ market), while 55% of day-neutral strawberries were sold in wholesale. On average, growers of short-day strawberries generated a profit of 22,300 $CAD/ha (29.10% of total income), and growers of day-neutral strawberries 37,962 $CAD/ha (29.50% of total income). Based on this study, both groups of strawberries in Ontario are highly profitable and with great potential for frofit increase.

Abstract:

Tearing is a common presenting complaint in infants referred to an ophthalmologist and may be the first sign of something as benign as an impermanent anatomic defect or as grave as congenital glaucoma. When tearing is chronic, parents of an affected infant are often frustrated by the persistent accumulation of fluid and mucopurulent material in the eye and on the eyelids and anxious that the condition may be a sign of a more serious problem. The best initial management of tearing in an infant is to take a detailed history, which often provides important clues as to the cause of tearing, and then to perform a thorough, systematic ophthalmic examination. Tears serve four main functions: (1) they form a tear film to keep the eye moist, (2) they lubricate the eye, (3) they keep the eye clear of particulate matter and debris, and (4) they provide a refractive surface on the corneal epithelium. The tear film comprises three layers: a thin inner layer of proteinaceous mucin coats and protects the eye, an aqueous layer keeps the eye moist and lubricated, and an outer lipid layer slows evaporation of the aqueous layer. Basal tears are produced by the accessory lacrimal glands located in the conjunctiva and keep the eye moist under steady-state conditions; normal patients have a tear meniscus (or “tear lake”) visible along the inner lower eyelid as a result of basal tear production. Irritation or emotional extremes can trigger reflex tear production by the main lacrimal gland in the superotemporal quadrant of the orbit, “flooding” the tear lake. The level of the tear lake is highest when the rate of tear production by the lacrimal glands exceeds the rate of tear drainage into the nasolacrimal system. Tears normally drain out of the eye through puncta located on the nasal portion of the upper and lower eyelids. They then enter the upper and lower canaliculi, which run inferiorly and medially before joining to form the common canaliculus, which conducts tears through the valve of Rosenmuller and into the lacrimal sac.

Abstract:

A modified version of the Edinburgh Duck wave energy converter has been studied recently at the University of Edinburgh. From the design point of view the key innovation was a modification of the wetted profile. Wave energy is converted into useful work by the same pitching motion as in the original Duck, but by means of a circular cylinder with an off centred axis of rotation. This recent study was focused on a Duck version designed for vapour compression desalination rather than electricity production. An hydrodynamic numerical model (WAMIT) was used to predict first-order hydrodynamics quantities and to select and optimize configurations. The results obtained showed that it was possible, following the appropriate control strategies, to obtain similar energy absorption capabilities as the in the cam shaped original Duck. A 1:33 scale model was built to validate the numerical predictions. This paper extends the already published numerical predictions and experimental results obtained with this model. Experimental tests in random waves and measurements of the mooring forces for different submerged volumes will be reported for the first time.

Abstract:

Growing concerns about global warming and depletion of fossil fuel have resulted in exploring alternative energy solutions such as renewable energy resources. Among those, marine and hydrokinetic and in particular wave energy have drawing more interest. Ocean waves are predictable, less variable, and offer higher energy density values. As per National Oceanic and Atmospheric Administration (NOAA), North Carolina ranks 6th with total 484 km coastline length. In this work, six-year National Data Buoy Center (NDBC) wave data from five stations along the North Carolina shore including Wilmington Harbor, Mansonboro Inlet, Oregon Inlet, and Duck FRF (17 and 26 m) are collected. The wave parameters such as wave height and period are analyzed and the potential wave power density values are calculated. The power production from the resource is estimated using wave energy converters. Storing excess energy in the form of hydrogen can be used for a variety of applications. Hence, the cost-performance analysis using the cost per unit method is conducted to obtain the maximum and average hydrogen production from the studied site. The results will be useful to a wide range of development activities in both academia and industry.

Abstract:

The last decade has seen the increase of solar and wind generation systems which has led to high grid penetration of such technologies. Currently, the issue of grid stability and reliability with increased levels of such non-dispatchable generation is of great fundamental concern. This paper reports on the results of analyzing 15 min monitored data over a whole year from a large university campus with over 50% solar penetration of one of its four sub-stations. Net loads or electric purchases are the differences between the campus electric load and the electricity production of the solar system. These net loads are analyzed both in terms of diurnal “duck curves” and as load duration curves in order to determine the frequency and magnitude of different ramping up and down events experienced during the on-peak and off-peak periods. The extent to which such events can be tempered by installing combined heat and power (CHP) systems is studied, and it is found that increases in levels of net load stability vary non-linearly with size of the installed CHP system. Though the results are specific to this case study, the methodology adopted and some of the results and conclusions reached would be useful to those performing similar evaluations in other parts of the world.

Abstract:

Successful deployment of large amounts of renewable solar and wind energy has created a pressing need for significant additions of grid connected energy storage. Excess renewable generation is increasingly necessitating curtailment or derating of renewable or conventional generators. The CAISO Duck Curve [8] illustrates the challenge caused by very large quantities of solar generation. Both large scale energy storage and flexible ramping are needed for renewable resources to be financially sustainable and to meet CO2 reduction goals. The Dispatchable Solar Combined Cycle (DSCC) integrates Concentrating Solar Power (CSP) with Thermal Energy Storage (TES) in a holistic combined cycle configuration to meet the challenges of the CAISO Duck Curve by delivering flexible capacity with dispatchable solar power. Energy cost from DSCC is comparable to that from a Combined Cycle Power Plant (CCPP), and substantially below the alternatives: Photovoltaic plus battery or Photovoltaic plus combustion turbine. DSCC also enable far higher integration of renewable power and far larger renewable capacity factors than the Integrated Solar Combined Cycle (ISCC), which typically has no storage. The innovative DSCC system: • uses energy storage to deliver power when it is most valuable, • increases the capacity factor to deliver more renewable energy, • improves the power plant Heat Rate to reduce fuel consumption, and • reduces the cost of power while addressing RPS and storage mandates. In DSCC, the CSP and TES are used primarily for latent heat: the evaporation of steam, and the Combustion Turbine (CT) exhaust gas is used primarily for sensible heating, especially superheating steam. This simplifies the integration of low-cost storage media, such as paraffinic oils or concrete, instead of molten salt, since high temperature storage is not needed. A single pressure, non-reheat steam cycle suitable, allowing for simplicity of design and operation, reducing costs and facilitating faster startup and ramping. With DSCC, the steam turbine generates about the same power as the CT, unlike a typical CCPP where about half the power comes from the steam cycle. The additional steam production reduces the Heat Rate about 25% compared to CCPP. The DSCC approach is ideally suited for repowering existing CSP plants, to provide firm capacity that can dispatch at valuable evening peak periods, increase the power output, and reduce fossil fuel use compared with conventional CCPP or peaking plants. This paper will outline the DSCC concept, and provide performance estimates for a reference plant.
