| Abstract |
This experiment was conducted on one hundred and twenty ducks (30 Dumyati, 30 Peking, 30 Muscovy and 30 Sudani ducks). The ducks were fed complete commercial diets, appropriate for respective species; Slaughter and slaughter value estimation were performed at the age of 12 weeks analysis of the chemical composition of meat was made on breast and thigh muscles. Cell-mediated immunity was examined by Phytohemagglutinin-P (PHA-P) at 10 weeks of age. The present result showed that Muscovy strain had significantly heavier body weight compared to remaining strains. Concerning sexual dimorphism, the Sudani strain (51.8%) has a greater dimorphism in body size between males and females followed by Muscovy (43. 7%) one. Both Muscovy and Peking ducks possess better feed conversion ratio than those (Dumyati and Sudani ones. Regardless of strain effect the males had significantly heavier body weight with more efficient feed conversion ratio than females ones. The Muscovy breed possesses better quality of meat than the Peking one due to lower body fat with respect to cell-mediated immunity, the present results showed that Dumyati breed in both sexes had significantly hyper responder to PHA-P injection at all times compared to other breeds. The results obtained in this study give some insight into the production parameters and immune response of the four breeds of ducks present in Egypt.
