Carcass Characteristics of Kacang Goats Fed Ration Containing MH-1 Variety of Kapok Seed Meal (Ceiba pentandra, GAERTN.)
This research aimed to study the carcass characteristics of Kacang goats fed ration containing kapok seed meal (KSM) as a component of the concentrate. The experiment was conducted in two stages. The first stage was to find out the best variety of kapok that will be used in the second experiment; the second stage was to determine the benefits of KSM on carcass characteristics. Twenty-five, 8 months old Kacang goats with initial body weight of 11.71±1.08 kg, were used in this experiment. The animals were housed individually based on completely randomized design (CRD) with 5 treatments and 5 replications. The rations were based on forage:concentrate ratio of 50:50 dry matter basis. The ration contained concentrates, with increasing levels of KSM, i.e.: R0 (napier grass + concentrate: rice bran, coconut cake, corn, urea + 0% KSM); R5 (R0 + KSM 5%); R10 (R0 + KSM 10%); R15 (R0 + KSM 15%); and R20 (R0 + KSM 20%). Drinking water was provided ad libitum. The result of first stage showed that KSM variety of MH-1 would be used as a component of the concentrate on the second experiment. The increasing level of KSM in the rations had significant effect (P<0.05) on physical characteristics of the carcass, such as dressing percentage (44.35%), carcass length (54.006 cm), fleshing index (130.59 g/cm), plumpness of leg (87.48%), loin eye area (5.06 cm2), and percentage of carcass meat (64.69%). It is concluded that MH-1 variety of KSM can be used as a feed component up to 20 % in the goat ration.
