Growth and Feed Conversion Efficiency of Malin Lambs in Intensive Production

Fourteen weaned Malin lambs (3-month of age), seven from each male and female lambs were fed with 3% of body weight of concentrate and ad libitum forage diet under intensive system for 3 months. Average daily weight gain (ADG) and feed conversion ratio (FCR) were analyzed at 6-month of age. On average the lambs consumed 72.26 and 63.38 g dry matter (DM), 9.48 and 8.35 g digestible crude protein and 47.06 and 41.44 g total digestible nutrients (TDN) for average daily gain of 0.11 and 0.09 kg in male and female lambs, respectively. Weaning body weight was not significantly different in the two sex groups while the final body weight after 90 days of intensive feeding was significantly higher in male (22.0 kg) than female (18.50 kg) lambs. Likewise, total body weight gain in the experiment and average daily gain (ADG) were also higher in male than female lambs. The male showed better weight gain than female lambs during the experiment. Both male and female lambs showed progressive gain in body weight over the experimental period while the rate of gain was better (p< 0.05) in male than female lambs. The feed conversion efficiency was better in male than female lambs with 5.64 and 6.26 feed conversion ratio, respectively in the two sex groups but the difference is not statistically significant. The study showed that there was an improvement in genetic quality of Malin breed since 1970’s particularly in ADG and body weight at 6-month age.
