Abstract


A study to observe the effect of high feeding level on body weight gain of male Javanese sheep (G) from different litter size was done in Bogor for three months. Eighteen male sheep aged 4-5 months were kept in flock of different litter size (LS1, LS2, LS3). The initial average body weight were 21.9, 21.2, and 18.6 kg per head for LS1, LS2 and LS3 respectively. Feed given was calculated based on dry matter (DM), 4.5% of body weight which consist of 85% concentrate DM and 15% grass DM. Concentrate given was GT03 with 16% crude protein and 68% TDN, and the forage was King grass. Results show that average daily weight gains (ADG) are 119.04,
124.48 and 134.52g/h/d for LS1, LS2, and LS3 respectively. The actual DM intakes are 4.2, 4.1, and 3.3% of body weight (BW) for each litter size respectively. The lowest feed conversion is resulted from LS3 (5.97), while that ofLSl is 8.94 and for LS2 is 8.46.
