Utilization of Leucaena leucocephala silage on growth and economic comparison in Santa Ines sheep อนิทริา มัตตาพงศ์

This experiment evaluate the use of Leucaena leucocephala as the sole fermented feed on growth of Santa Ines sheep. Six, 6 months old, males, Santa Ines sheep with body weight ranged from 16-29 kg, were used in the experiment. The animals were divided into two groups and were randomly assigned to receive dietary treatments according to a t-test design. Dietary treatments were 1) L. leucocephala silage and 2) fermented TMR. The animals were fed twice daily at 8.00 and 16.00 h for 50 days. Feed intake, body weight and economic values were recorded. The results found that the feed intake and ADG of sheep fed T1 and T2 were not significantly different. The FCR of sheep fed T2 (6.97) and T1 (7.03) significantly differ (P<0.05). Feed cost of T1 and T2 were 43.79 and 63.84 B/h, respectively. Economic return of sheep fed T1 and T2 were 315.57 and 286.46 B/h, respectively. Based on the present result, it can be suggested that L. leucocephala silage has promising potential for sheep production in term of animal performance and cost effectiveness.
