Effect of Nutritional Restriction Levels and Glycerol on Growth Performance of Local Male Lambs

Year: 2025
Type: article
Abstract: This research investigated the effect of nutritional restrictions and glycerol addition on the growth performance of local male lambs. The experiment was conducted on 24 local male lambs aged 3 - 3.5 months weighing 18±1.13 kg on average. The lambs were randomly assigned to six treatment groups. In Phase 1, the findings showed that the control group was more efficient in reducing the cost of producing 1 kg of weight gain than the glycerol group. The 0% feed restriction group outperformed the 70% and 50% groups in most production traits, with the 0% and 70% groups showing better feed conversion ratios and lower production costs than the 50% group. In Phase 2, adding glycerol reduced dry matter intake but maintained the lower cost for weight gain in the control group. The 0% feed restriction outperformed other treatments in terms of weight and feed intake. However, the 50% feed restriction group showed better feed efficiency, with the best feed conversion ratio and production cost. For the combined phases of nutrition restriction and free re-alimentation, the study found the control group had a significantly lower cost for producing 1 kg of weight gain compared to the glycerol addition group. Among the feed restriction treatments, the 0% group led in effectiveness followed by the 70% and 50% groups in terms of weight gain, feed intake, and other production indicators. In conclusion, the best treatment was recorded by the 70% feed restriction without glycerol group in terms of lowest cost for weight gain, reduced feed intake, and final weight similar to the control
