Vol. 26, No. 1, 2009Indonesian Agricultural Research AbstractsDecision to develop a livestock breed needs to be adapted to the animal production potential and itssupporting resources. In this case, production and feed conversion to synthesize body tissues are the mainchoice in examining the animal potency. A feeding experiment was conducted to compare relative growthof weaning etawah crossbred goats and kacang goats (initial average weight of 20.3 kg). A restrictedamount (200 g/d) of concentrate containing 17.7% protein and 11.2 MJ ME/kg dry matter was offered toeach of 25 etawah crossbred goats and 22 kacang goats. Fresh napier grass was offered ad libitum. Waterwas available at all time. Data was analyzed using t-test with unequal replicates. The results showed fastergrowth of etawah crossbred goats than that of kacang goats (36.5 vs 19.8 g/day) despite no significant feedintake difference.114 PURBOWATI, E.Growth of carcass and carcass component of local male lamb reared in the village.

Local lambs used as subject research whichwere from Temanggung, i.e. healthy male lamb, aged 1.5-12 months which slaughtered at 6 categoriesslaughter weight with range 5-30 kg. The objective of the research was to study the growth of carcass andits components (meat, fat and bone) with allometric model Y = aX b . The results showed that local malelamb with body weight of 6.80 kg - 31.40 kg (the average 17.99 kg ± 8.40 kg) yielded 36.60% - 49.41% ofcarcass (the average 44.29% ± 3.71 %). Carcass with weight 3.22 kg - 14.80 kg yielded carcass muscle,carcass fat and carcass bone of 56.03% - 65.23% (the average 62.23% ± 2.34%), 3.93% - 21.13% (theaverage 12.66% ± 4.53%), and 17.59% - 29.21% (the average 21.94% ± 3.02%), respectively. Meat andfat (without kidney fat and pelvis fat) were 66.69% - 78.3% (the average 73.63% ± 3.71%) and meat-boneratio was 2.28 - 4.45 (the average 3.43 ± 0.60). The growth of carcass components that was relative toempty body weight and carcass weight showed that carcass weight fixed, carcass muscle fixed, carcassbone decreased, and carcass fat increased with the increasing of empty body weight and carcass weight.The growth of fat depot that was relative to total carcass fat weight showed that subcutaneous fat weightincreased, intramuscular fat and kidney fat and pelvis fat fixed with the increasing of total carcass fatweight. It was concluded that local male lamb in Temanggung generated high carcass containing fat andthe development of this carcass fat concentrated in subcutaneous fat simultaneously increasing of bodyweight.L53 ANIMAL PHYSIOLOGY - REPRODUCTION115 BELLI, H.L.L.Hormonal patterns of pre and postcalving bali cows supplemented with multinutrient blocks.
