Abstract:

In a Completely Randomized Design, thirty two ram lambs (11.3 kg ±0.3) were tested with four feeding regimes to evaluate the effect of feed restriction followed by realimentation on plane of nutrition and carcass parameters. A 8 week restriction period was followed by a 4 week realimentation phase and the animals divided into 4 groups (T1 to T4) were subjected to feed restriction at 0, 10, 20, and 30 percent, respectively. After realimentation period, slaughtered animals were studied for carcass parameters. The weight of the skin, meat produced and meat to bone ratio were found to be higher (P<0.05) for maximum restricted animals. No significant differences in DCP and TDN intake (kg/day) were observed among the treatments but tended to be higher in T4 as compared to other treatments. The DE intake (M cal) and ME intake (M cal) were higher in T4 and were non-significant. Similar trend was observed during realimentation phase also. The total cost of feed consumed per lamb was decreased with the level of restriction increased from T1 to T4. During restriction phase the feed cost / kg gain per lamb was increased with the level of restriction increased from T1 to T4. During re-alimentation phase, the feed cost / kg gain per lamb decreased from T1 to T4 with increased level of restriction while the feed cost / kg gain per lamb was lower in T4 compared to T1, T2 and T3. It was concluded that the increase in the feed restriction up to 30% in diet has improved the carcass yield and also has reduced the cost/kg gain in ram lambs.
