Abstract
This experiment was conducted at the Native Chickens Breeding Station / IPA Agricultural Research Center, from 19th Dec. 2001 to 29th Jan. 2002. A total of 660 male broiler breeder (line CD) chicks, one day old were randomly allocated into 11 groups of three replicates per group. Chicks in the first 10 treatment groups were subjected to either surgical removal of uropygial gland (UG) or removal of UG papilla at different ages (3,10,17, 24 and 31 days) while the chicks in the 11* treatment group were used as control. The results indicated that the surgical removal of UG at 17 days old significantly improved the final body weight (at 6 weeks old). The final body weights for birds in this group were 1565.8 g. While the final body weight for control birds was 1418 g. It was concluded from this study that the surgical removal of UG of birds at 17 days old were realized the best results in final body weight, feed consumption and cumulative body weight gain. Uropygialctomy seemed to be better than the removal of UG papilla in most of characteristics included in the current experiment.
