Abstract:
To investigate the distribution and genetic variation in four vertically transmitted duck pathogens, including duck hepatitis B virus (DHBV), duck circovirus (DuCV), duck hepatitis A virus 3 (DHAV-3), and avian reoviruses (ARV), we conducted an epidemiology study using PCR and RT-PCR assays on a duck population. We found that DHBV was the most prevalent virus (69.74%), followed by DuCV (39.48%), and then ARV (19.92%) and DHAV-3 (8.49%). Among the 271 duck samples, two, three or four viruses were detected in the same samples, indicating that the coinfection of vertical transmission agents is common in ducks. The genetic analysis results showed that all four identified DuCV strains belonged to genotype 1, the DHAV-3 strain was closely clustered with previously identified strains from China, and the ARV stain was clustered under genotype 1. These indicate that different viral strains are circulating among the ducks. Our findings will improve the knowledge of the evolution of DuCV, DHAV-3, and ARV, and help choose suitable strains for vaccination.

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. Keywords: hybrid duck, Peking duck, Production PerformÂ

Abstract:
Broiler ducks are ducks that are able to grow quickly and can convert feed efficiently into meat with high value. Duck meat has a good structure and structure of the meat. The good structure of duck meat is now popular with the public, because the taste of the meat is delicious and savory. Broiler ducks that are known by the public include hybrid ducks and peking ducks. The demand for duck meat that continues to increase does not change with the availability of duck meat available in the market, to meet the needs of the community. It is possible to breed broiler ducks as proof that the poultry business for ducks is wide open with the promised profit prospects. The purpose of this study was to determine the productivity in broiler duck cultivation which can increase body weight gain quickly, economically and produce meat that has high nutrition to meet public demand. The research method used is literature review by analyzing relevant articles and focusing on the productivity of broiler duck farming. Based on maintenance for 6 weeks, the data obtained was the consumption of hybrid rations as much as 6,514 g/head while in peking ducks as much as 7,601 g/head, PBB in hybrid ducks was 1,237 g/head, while for peking ducks 1,699 g/head, FCR in ducks hybrid 5.29 and peking duck 4.49 and mortality of hybrid duck 4% and peking duck 12%. The weight gain, mortality, and feed conversion of peking ducks were higher than that of hybrid ducks. The conclusion from the results of the study that the best duck genotype to produce FCR was hybrid duck and production performance which included body weight gain, feed consumption and feed conversion in peking ducks and hybrid ducks.

Abstract:
In India, the contribution of ducks for egg and meat production is next to chicken. There are many advantagesof duck production over chicken. The important available ducks in the country are few exotic breeds and locallyavailable indigenous ducks. Ducks can be reared under intensive, semi-intensive and extensive rearing system.However, in India, ducks are mostly reared in small flock size as subsidiary source of income. The major duck basedintegrated farming system are duck-fish, duck-rice and duck-rice-fish integrated farming system. Feed is the majorfactor in livestock and poultry production system as it accounts about 70-75% of the total cost of production. Tominimize the cost of production, many locally available alternate or unconventional feed ingredients, viz. azolla,cassava, broken rice are used for feeding of ducks. The constraints of duck farming are mainly the unavailability ofsuitable germplasm, scarcity in natural feed resources, drying of natural water bodies, difficulty in the availabilityof vaccines, poor marketing facilities, etc. In India, there is ample scope for duck production to meet egg and meatdemand of the country. Suitable duck breeds or varieties need to be developed for rural backyard duck farming.Comprehensive feeding packages along with scientific management practices for different types of ducks should beformulated for economic production of duck eggs and meat. There is a need for establishment of hatcheries and other infrastructures in rural areas to promote duck farming for sustainable livelihood of the people.

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.

AbstractIntroductionCoinfection of goose parvovirus (GPV) and duck circovirus (DuCV) occurs commonly in field cases of short beak and dwarfism syndrome (SBDS). However, whether there is synergism between the two viruses in replication and pathogenicity remains undetermined.Material and MethodsWe established a coinfection model of GPV and DuCV in Cherry Valley ducks. Tissue samples were examined histopathologically. The viral loads in tissues were detected by qPCR, and the distribution of the virus in tissues was detected by immunohistochemistry (IHC).ResultsCoinfection of GPV and DuCV significantly inhibited growth and development of ducks, and caused atrophy and pallor of the immune organs and necrosis of the liver. GPV and DuCV synergistically amplified pathogenicity in coinfected ducks. In the early stage of infection, viral loads of both pathogens in coinfected ducks were significantly lower than those in monoinfected ducks (P < 0.05). With the development of the infection process, GPV and DuCV loads in coinfected ducks were significantly higher than those in monoinfected ducks (P < 0.05). Extended viral distribution in the liver, kidney, duodenum, spleen, and bursa of Fabricius was consistent with the viral load increases in GPV and DuCV coinfected ducks.ConclusionThese results indicate that GPV and DuCV synergistically potentiate their replication and pathogenicity in coinfected ducks.

Abstract:
Duck (Anas platyrhynchos) was one type of potential poultry producing eggs. Efforts to increase productivity can be done through the selection of good breeding stock, provision of adequate food in quantity and quality as well as the provision of additional feed (feed additive). Calcium carbonate was a mineral needed by a group of ducks for egg shell formation. The purpose of the research was quality of the local duck eggs Pengging include ducks, duck Tegal and duck Magelang based on the quality of its shell. This study uses a completely randomized design (CRD) with three treatments (Pengging duck, duck Ducks Tegal and Magelang) and 6 replication.The measured variable was the index of egg shell, eggshell weight, eggshell thickness and eggshell calcium. Data were analyzed using Analysis of Variance (ANOVA) with a differentiating factor is the type of duck. Real different data analyzeda further test using Least Significant Differences Test (LSDT) at the level of 95%. The results of this research indexshowed that ducks Tegaland duck Pengging no significant difference but significantly different with Magelang ducks. Weight eggshell and eggshell thickness showed no significantly different for the three types of local ducks. Eggshell calcium levels showed that Magelang ducks and duck Pengging no significant difference but significantly different with Tegal ducks.Conclusion of the study was index eggshell and eggshell calcium could affect the quality of the eggshell.

Abstract:
Species identification of the components of various duck breeds has revealed that the lowest identifiable number of components depends on the breed. The results (shown on the agarose gel) of a species-specific PCR reaction for Rouen ducks were less intense than the results for the same amount of components from other popular duck breeds, suggesting differences in the Rouen duck genome. Therefore, the present study aimed to identify part of the Rouen duck’s gene sequences and to develop two new primer pairs. The first pair enables breed-independent identification of duck DNA, and the second distinguishes Rouen ducks from Chinese and Indian Runner ducks. The sequencing reaction yielded sequences of 1386 bp in length, and the identified sequence differs by around 7% from the sequences of Chinese duck species. The detected sequence contributes to improving species identification methods for duck DNA. On its basis, two primers for the identification of duck DNA were designed. The first allows for DNA amplification with the same sensitivity regardless of duck breed. The second primer’s pair is breed specific, and it distinguishes Rouen ducks from Chinese and Indian Runner ducks. Both methods are very sensitive (0.05%).

Abstract:
Ruddy Ducks in the Chilcotin parklands of British Columbia nest in late June, July and early August, later than most other waterfowl species breeding in southwestern British Columbia, Canada. This thesis considers factors that may affect the timing of breeding in Ruddy Ducks by comparing Ruddy Ducks to Barrow's Goldeneye and Bufflehead (species that breed early but do not renest) and to American Coot (a species that breeds early and is able to renest). These factors include predation, flooding and desertion of nests, feeding behavior of ducklings, abundance of food, availability of green vegetation and fluctuations in temperature. Possible advantages of late breeding include reduced nest predation and higher ambient temperature during incubation. Longer dive durations and more frequent feeding and resting by Ruddy ducklings may enable ducklings to maximize energy for growth. Reduced nest flooding late in the season, dependence on green vegetation for nesting and greater abundance of food for young in summer were not demonstrated by this study. Therefore, these factors apparently do not explain the timing of breeding in Ruddy Ducks in southwestern British Columbia. Despite insufficient time to renest and shorter time for ducklings to mature before ponds freeze, the average number of 2B age class young produced per pair of Ruddy Ducks was similar to that of American Coots. Forty percent of nesting Ruddy females did not hatch any young, whereas almost all nesting Coot females successfully hatched young; however, survival of Ruddy ducklings to 2B age class (four weeks old) was higher than that of American Coots, Barrow's Goldeneye and Bufflehead.

Abstract:
The study investigated the effect of age, feed restriction and photoperiod during rearing upon mature liveweight, body composition and sexual maturity in ducks. The literature on wild Mallard is extensive but there is very little published evidence relating to d~estic duck. Experiments were conducted with Pekin duck selected for meat production. Unrestricted growth to maturity was shown to produce uncoordinated development of ovarian follicles which caused internal OVUlation and reduced rate of lay. Restricting growth by limiting feed intake during rearing delayed physiological development and sexual maturity and improved synchronization between growth and sexual development which improved breeding performance. Severe restriction of feed intake up to 22 weeks reduced mature IIveweight and delayed sexual maturity. There was a linear relationship between liveweight of 1;reatment groups at 20 weeks of age and mean age at sexual maturity. However, it was found that ducks must attain at .Ieast 65 percent of the liveweight of ad-libitum fed controls before they could achieve sexual maturity. Opportunities for altering body composition by varying nutrient intake during rearing were shown to be very limited. There was a fixed relationship between body composition and bodyweight. Changes in natural or artificial day length during rearing were shown to affect age at sexual maturity but the response was affected by restricted feeding. Delaying sexual maturity by restricted feeding and controlling daylength during rearing both increase subseQuent rate of lay, egg production and egg weight but there "as no improvement in breeding performance measured to a fixed age, as a result of delaying sexual maturity beyond 26 weeks of age. 1 2 Equations are given for responses 01 body'weight, sexual maturity, egg number and egg size to feed and light treatments. These could be used to build a predictive model for practical use.

Abstract:
With increasingly warming climate, many bird species have been forced to respond to environmental changes, and the long-tailed duck (Clangula hyemalis) is no exception. The populations of the long-tailed duck have been in decline the past few decades and the species is classified as globally vulnerable and near threatened in both Iceland and Sweden. The long-tailed duck is a circumpolar, migratory sea duck. Its migratory routes and wintering and breeding sites might play an important part in gene flow between populations. The aim of this project was to get a clearer image of the substructure of the long-tailed duck in the northern hemisphere to help identify populations possibly at risk. This was investigated by exploring differences in mitochondrial DNA between the global populations, and by studying the Icelandic wintering and breeding populations in particular applying whole genome sequencing. To do this, samples were obtained for mitochondrial DNA analyses from a previous study by Wilson et al. (2016) from North America and East Russia, samples from other populations around the northern hemisphere as well and new samples from Iceland. Museum samples from Iceland were used for whole genome resequencing. Mitochondrial analyses included haplotype identification, population comparisons, mismatch and neutrality tests. Whole genome analyses included neutrality tests, principal component analysis and genetic admixture analysis.The mitochondrial results revealed two distinct lineages for the long-tailed duck. Two populations showed a difference from the other populations; the Icelandic breeding population and the Yukon-Kuskokwim Delta population from Alaska, which are the southernmost breeding populations. The Yukon population might have been previously isolated with refugial population intermixing. For the Icelandic populations, the mitochondrial results showed little intermixing between the winter and breeding populations. The whole genome results showed more complicated results for the Icelandic populations, with admixture in some individuals. This suggests that there seems to be more variation in the genome than implied by the mitochondrial DNA.

Abstract:
Complete and precise identification of types is essential to the effectiveness of programming aids such as refactoring or code completion. Existing approaches that target dynamically typed languages infer types using flow analysis, but flow analysis does not cope well with heavily used features such as heterogeneous containers and implicit interfaces. Our solution makes the assumption that programs that are known to work do not encounter run-time type errors which allows us to derive extra type information from the way values are used, rather than simply where those values originate. This is in keeping with the “duck typing” philosophy of many dynamically typed languages. The information we derive must be conservative, so we describe and formalise a technique to ‘freeze’ the duck type of a variable using the features, such as named methods, that are provably present on any run of the program. Development environments can use these sets of features to provide code-completion suggestions and API documentation, amongst other things. We show that these sets of features can be used to refine imprecise flow analysis results by using the frozen duck type to perform a structural type-cast. We first formalise this for an idealised duck-typed language semantics and then show to what extent the technique would work for a real-world language, Python. We demonstrate its effectiveness by performing an analysis of several real-world Python programs which shows that we can infer the types of method-call receivers more precisely than can flow analysis alone.

Abstract:
A water quality study was conducted on Big Duck Creek and Little Duck Creek near Elwood, Indiana during the summer, autumn and winter of 1978 - 1979 and compared to measurements made in 1938.Samples were analyzed for dissolved oxygen, biochemical oxygen demand, suspended solids, ammonia, total coliform bacteria, hydrogen ion concentration and temperature. Significant differences in concentrations were observed for each environmental parameter measured in 1979 when evaluated on a basis of sampling location. With the exception of dissolved oxygen concentrations, the effect of stream volume on the concentration of environmental parameters was in most instances small.When the up and downstream stations were compared, a definite decrease in water quality was noted. The dissolved oxygen concentrations decreased as the water flowed through the city. Due to increased organic loading, the biochemical oxygen demand increased in the downstream area.Elwood increased the suspended solids level of Big Duck Creek. Agricultural and urban runoff together with untreated sewage discharges significantly increased the suspended solids level within the inner city region. Dilution by treated sewage as well as cleaner water from Little Duck Creek help reduce the suspended solids level in the downstream location. Relatively high ammonia concentrations were observed in the upstream portions of the creeks. This was apparently related to farm practices. The higher readings of ammonia were noted after animal manure was spread on the fields along the stream. The downstream levels were also high. This was probably due to ammonia in the effluents of the sewage treatment plant. In contrast, only small changes in the hydrogen ion concentration was observed throughout the creek.The number of total coliform bacteria increased in the center of town because of a sewer bypass into the creek. Below Elwood the concentration of bacteria decreased due to dilution with disinfected effluents from the sewage treatment plant.Except for a noticeable increase in biochemical oxygen demand and ammonia, the Elwood sewage treatment plant effluent together with flow from Little Duck Creek appears to improve Big Duck Creek's condition as it leaves the city to join White River.Significant differences were observed between measurements made in 1938 and 1978 - 79. Results of the study showed a significant improvement in water quality of Big Duck Creek since 1938. This was probably due to the construction of Elwood's wastewater collection system and sewage treatment plant in the 1940s.However, there was still degradation of water quality within the city due to untreated wastewater discharges. Consequently, emphasis should be focused on the inner city problem since Elwood residents would be in the proximity to this area.

Abstract:
Harlequin ducks (Histrionicus histrionicus) are sea ducks that migrate inland each spring to nest along fast-flowing mountain streams. They are considered one of the most imperiled duck species in North America and occur in two distinct populations on the Atlantic and Pacific coasts. The Pacific coast population includes Washington State, where harlequin ducks breed in the Olympic, Cascade, and Selkirk Mountains. This species is designated as a Management Priority Species by the National Park Service within North Cascades National Park Service Complex (NOCA). This report summarizes harlequin duck surveys conducted during 15 years across a 27-year period (1990 and 2017) on major streams within NOCA, and incidental observations collected from 1968–2021. The primary objectives of these surveys were to 1) document the distribution and abundance of harlequin duck observations within NOCA boundaries, 2) describe productivity (number of broods and brood size), 3) describe breeding chronology of harlequin ducks, and 4) describe habitat characteristics of breeding streams. Sixty-eight stream surveys over 15 years resulted in observations of 623 individual harlequin ducks comprising various demographics, including single adults, pairs, and broods. In addition, we collected 184 incidental observations of harlequin ducks from visitors and staff between 1968–2021. Harlequin ducks were observed on 22 separate second- to sixth-order streams throughout NOCA across the entire 53-year span of data, both incidentally and during harlequin duck surveys by Park staff. Harlequin ducks were detected on 8 of the 13 streams that were actively surveyed. Excluding recounts, 88.7% (n = 330) of individual harlequin duck observations during surveys occurred in the Stehekin River drainage. Between all surveys and incidental observations, 135 unpaired females without broods were sighted across all NOCA waterways. Thirty-nine broods were recorded between NOCA surveys and incidental observations, with a mean brood size of 3.61 (± 1.44 SD; range = 2–10). Breeding pairs were recorded as early as April 5 and were seen on streams until June 15, a period of less than seven weeks (median: May 2), but most pairs were observed within a 3-week span, between April 26 and May 17. Single females (unpaired with a male, with (an)other female(s), or with a brood) were observed on streams between April 26 and August 25 (median: July 3), though most observations were made within a 5-week period between June 12 and July 19. Habitat data collected at adult harlequin duck observation sites indicate that the birds often used stream reaches with features that are characteristic of high-energy running water. While adults occupied all instream habitat types identified, non-braided rapids and riffles were used most frequently, followed by pools and backwaters. Larger instream substrate sizes (cobbles and boulders) were present at most observation sites. Adult harlequin ducks were more often found at locations that lacked visible drifting or lodged woody debris, but drift debris was a slightly more abundant debris type. The presence of gravel bars and at least one loafing site was common. Adult harlequin ducks were more often observed in association with vegetation that offered some cover over the channel, but not where banks were undercut. The average channel width at adult observation sites was 34.0 m (range: 6-80 m; n = 114) and 27.6 m (± 15.7 m; range: 10-60 m; n = 12) at brood observation sites. Compared to adult harlequin duck sites, broods were observed more frequently in low velocity habitat (pools, backwaters), but rarely in rapids. Cobble and boulder substrates were still the most dominant substrate type. Contrary to adult ducks, broods were observed most often observed in meandering stream channels, a morphology indicative of low gradient, low velocity stream reaches. Most broods were observed in stream reaches with gravel bars, loafing sites, and...

Abstract:
Canada geese, snow geese, ducks, and American coots all have been implicated in agricultural crop and turf damage. Generally, goose, duck, and American coot damage to crops, vegetation and aircraft can be difficult to identify. Usually the damage to crops or vegetation shows signs of being clipped, torn, or stripped. Tracks, feces, or feathers found neat the damage can be used to help identify the species. Damage to aircraft is obvious if the bird is recovered, but if not, and only bird parts are recovered, a scientific analysis is required. Canada geese, snow geese, ducks, and American coots are federally protected by the Migratory Bird Treaty Act (MBTA), which stipulates that, unless permitted by regulation, it is unlawful to “pursue, hunt, take, capture, kill, possess, sell, barter, purchase, ship, export, or import any migratory birds alive or dead, or any part, nests, eggs, or products thereof.” Generally, geese, ducks, and coots can be hazed without a federal permit in order to prevent damage to agriculture crops and property with a variety of scare techniques. In most cases, live ammunition cannot be used.
