| Abstract |
A total number of 120 male Muscovy ducks were used in this study. At the beginning of week 12(age) drakes were randomly divided into equal four groups. Drakes in group 1were subjected to 24 h light: those in group 2 subjected to intermittent light regime of 3 h light: 1 h dark (make 18 h light: 6 h dark); drakes of groups3 were subjected to natural day light and drakes of groups 4 were subjected to 1 h light: 3 h dark ( make 6 h light: 18 h dark). During the experimental period (12 10 27 weeks) all drakes were fed ad lib on diet of 15.5% crude protein and 2724 Kcal ME/kg. Some physiological and reproductive performances of male Muscovy ducks were determined
Seminal plasma total protein and albumin were significantly higher in groups 1 and 2, while, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were significantly higher than the other groups.
Seminal plasma protein electrophoresis showed that treatments 1 and 2 caused activation protein band with molecular weight> 100 kDa in these groups than in the other groups. Testes weight and testosterone concentration increased significantly (P<0.05) in birds subjected to 24h light and 18 h light: 6 h dark compared with other groups. Also, plasma total protein, albumen and cholesterol decreased significantly (P<0.05) in birds subjected to 6 h light: 18 h dark compared with other groups. It can be concluded that applying the intermittent light regime of 18 h light: 6 h dark tend to improve all measurements studied without any physiological side effect.
