Abstract

In this study effect of different WEANING AGEs on feedlot performance of FARAHANI MALE LAMBS was studied. A number of 16 male 45, 60, 75 and 90 days-old lambs were randomly selected, weaned and fattened for 90 days. The study was carried out on a completely randomized design with four weaning weights in four replicates. Results showed that increasing weaning weight significantly increased daily feed intake, warm and cool carcass weights, but had no significant effect on total live weight, shrunk body weight and carcass shrunk percent. Thus, no difference was observed in average daily gain between 45 and 60 days ages. Mean of feed conversion ratio for 45, 60 and 75 days-old lambs was not significantly different; however, it was significantly lower than 90 days weaning weight lambs. According to no significant changes in total weight changes, shrunk body weight and carcass shrunk percent in different weaning weights and as feed conversion ratio for 45, 60 and 70 days-olds was statistically the same and better than 90 days weaning weight in addition to economical conditions which can be formed by selling the unused milk and decrease in animal aggregation in pastures, 60 days age may be suggested for weaning weight of FARAHANI MALE LAMBS for fattening.
