Abstract

This experiment was conducted to investigate the effect of different periods of lamb suckling on CARCASS CHARACTERISTICS of Lori– Bakhtiari male and female lambs. Sixty six male and female lambs used. All lambs were born at same season and were randomly selected. They were weaned at 60, 90 and 120 days of age and put in a 6-month FEEDLOT period. A completely random design with factorial method (sex and weaning age) was used. At the end of FEEDLOT period, 15 male and 15 female lambs (10 lambs of every weaning age and in total 30 lambs) were randomly selected, slaughtered and their CARCASS CHARACTERISTICS were determined. The least squares means of final body weight in different weaning age (60,90 and 120 days weaned) were 44.64, 43.01 and 41.30 kg, respectively, and was significantly higher for 60 days weaning age group (p<0.05). Mean of cold carcass dressing percentage of 2nd group (90 days weaned) was significantly lower than other groups (p<0.05). The mean of total carcass meat and subcutaneous fat different weaning ages were not significant. Subcutaneous fat of female lambs were higher than male lambs (p<0.05), but fat-tail of male lambs were higher than females (p<0.05). In conclusion, the result of this experiment showed that appropriate WEANING PERIOD (60 days). Because in this group, final body weight, carcass cool weight and dressing percentage were more than 2ndand 3rd (90 and 120 days weaned) groups and other CARCASS CHARACTERISTICS and physical composition in differences weaning ages were not significant.
