Effect of Weaning at Different age intervals on the growth rate of Broiler Rabbits
نویسندگان
چکیده
Fifty broiler rabbit business were divided into five groups based on their age at weaning (3,4,5,6 and 8 weeks of weaning as group I, group II, group III, group IV and group V respectively). The average daily gain in the given group was 17.71, 18.64, 19.00, 20.86 and 21.07 gm/day respectively at the end of 12 week of the study. It was inferred that the difference was non-significant and also no significant difference was observed between the sex.
