Abstract

On-farm experiments were carried out in dryland farming in Bali for 48 weeks to study the effect of flock size on the growth and carcass characteristics of cross-bred goat fed gliricidia-supplemented diet. Eighty four bucks with average live weight of 15.87 kg were allocated in a completely randomized block design arrangement, consisted of three treatments and four blocks. The treatments were $3goats/2.7m^2$ (A), $6goats/5.4m^2$ (B) and $12goats/10.8m^2$ (C), while the floor density was the same ($0.9m^2$ per goat). Feed consumed by goat B was similar (p > 0.10), while feed consumed by goat C was lower (p < 0.10) than goat A. Live weight gain of goat B and C were lower (p<0.05) than goat A. FCR of goat B was higher (p < 0.10) than goat A, while FCR of goat C was similar (p > 0.10) with goat A. Goat B has heavier (p < 0.10) head and digestive tract, while goat C has heavier (p<0.10) hindlegs and digestive tract than goat A. Goat B has lighter (p < 0.10) shoulder, while goat C has lighter shoulder and heavier legs (p < 0.10) than goat A. The carcass quality (measured in terms of loin eye muscle area, meat, bone and fat portions) were not affected (p > 0.05) by the flock sizes.
