Figure 3. Feed conversion rates of the sexes within the three breeds. There were no major differences among breeds or between sexes within breeds in most carcass traits, the exception being body fat which was lowest in the Muscovy Table 2. Table 2. Unlike the Pekin and Kunshan ducks, the Muscovy has a greater dimorphism in body size between males and females. Males grew faster and yielded heavier body weight than females Figure 2. A similar trend was observed by Van der Sluis in relation to Muscovy ducks and their growth rates.
Bochno et al also reported that male ducks grew faster with more efficient feed conversion than females, which supports the result obtained in this experiment. Bochno et al reported that feed conversion was more efficient in Muskovy ducks than Pekin. Perez showed that Pekin ducks had a feed conversion at 8 weeks of 2. Other researchers Duong and Nguyen ; Luong et al reported feed conversion ratios of 2. These figures also support those obtained in this experiment. Two possible reasons for the tendency for higher dressed and eviscerated percentages of the Muscovy ducks are less plumage and smaller internal organs when compared to the Pekin and Kunshan ducks.
Luong et al evaluating the growth performance of CV Super-M ducks under two management systems, reported breast muscle yield of These figures are significantly lower than those obtained in this experiment. Szasz and Bogenfurst indicated that at 12 weeks the Pekin ducks had fat percentages of 20 vs 12 in the Muscovy and Mule ducks, which substantiate the results obtained in this trial. Other researchers Garachka and Kas Yanenka reported body fat percentages for Pekin and Muscovy ducks to be The result from this trial indicated that the Muscovy ducks possess better quality meat than the Pekin and Kunshan due to lower body fat.
The highest profit margin was obtained from the Muscovy ducks Table 3. Table 3. Costs — Benefit analyses of the three breed types at the end of eight weeks Parameters Pekin drakes Pekin hens Kunshan drakes Kunshan hens Muscovy drakes Muscovy hens Feed intake, kg.
This analysis was calculated in Guyana dollars 1. The major factors contributing for the economic placement of the Muscovy ducks are; the higher price paid for the meat and secondly their superior biological efficiency when compared to the Pekin and Kunshan ducks. The results obtained in this study give some insight into the production parameters of the three breeds of ducks present in Guyana.
Based on the results obtained differences and similarity exist among the three breed types for the measured production parameters. The economic assessment of the three breeds of duck indicates that the Muscovy ducks were more economical for both cost to produce 1kg live weight and cost per unit gain, followed by the Pekin and Kunshan ducks respectively.
The main factors contributing to the higher profit margin of Muscovy ducks are; the higher price paid for the meat and to a lesser extent the superior biological efficiency of the Muscovy ducks as against the Pekin and Kunshan breeds.
The authors wish to express our appreciation of the kindness of Mr. Paul Biometrician in analyzing our data from the experiment. Number3, 18 CAB International.
Pownal, Vermont. SAS Institute Inc. Go to top. Key words: Carcass, ducks, Kunshan, live weight gain, Muscovy, Pekin Introduction There is an increasing demand for animal protein, and duck production may be able to help meet this demand.
Therefore, the objectives of this study were to: To compare the growth production parameters of the three breeds. To evaluate the carcass quality of the three breeds. To determine the cost of production of the three breed types. Animal selection and management One hundred and fifty, day old, male and female ducklings of the Pekin, Kunshan and Muscovy breed types were selected and used in conducting the trial.
Brooding management Ducklings were raised on concrete floors with five centimeters thick wood shaving as bedding and infrared light was used as the source of heat. Grower management After the three weeks brooding period was over the ducklings were shifted to a separate grower house and reared on a concrete floor with 4 cm thick wood shaving, up to the end of the experiment. Results There were no differences in live weight gain among the male sexes for the three breeds Figures 1 and 2.
Growth curves of the three breeds and sexes. Figure 2. Livestock Research for Rural Development 18 11 During breeding, the birds must observe the cleanliness and freshness of the air inside the enclosures. When breeding ducks, important points are taken into account:. Before the first placement of birds in cages, disinfection is carried out. The poultry house is ventilated, cleaned, feeders and drinkers are treated with an antiseptic. The enclosures are closed for quarantine for 20 days.
Feeding livestock with ready-made feed is simple and affordable. Additionally, the bird is fed grass. Birds grow quickly on this diet. The disadvantage of this type of feeding is the high cost. With natural feeding, simple foods are included in the diet, grazing is organized.
A balanced diet allows poultry to grow quickly. Adults are fed twice a day, young animals are given food times at knocks. When grazing, ducks are fed in the aviary only in the evening. Feeding ducks is not a problem and does not require large financial costs.
It is enough for the livestock breeder to monitor the cleanliness, freshness of the feed, to choose the right balanced diet. If you follow simple rules, ducks gain weight quickly and produce quality meat. Content 1 Average weight of ducks 2 Factors affecting performance 3 How to feed ducks to gain weight?

Ducks do not weigh anything, this is because they float and fly. The average weight of a mallard is almost 3 pounds for both male and female. The average weight of a Pekin duck is 8 to 11 pounds.
