EVALUASI PEMBERIAN PAKAN DENGAN JUMLAH MULTINUTRIENT BLOCK YANG BERBEDA SEBAGAI SUPLEMEN TERHADAP PERFORMANS KAMBING KACANG

Abstract

Giving multinutrient blocks as a feed supplement aims to catalyze more efficient use of poor quality animal feed. This study aimed to get good performance of Kacang goats through the providing of the right amount of multinutrient blocks (MNB). The experimental method used 12 male goats which were divided into 3 groups based on their body weight, K1 (18,75 ± 1,25 kg), K2 (16,20 ± 1,20 kg) and K3 (14,20 ± 1,20 kg). Corn forage and concentrate fed as basal feed with a composition of 20: 80. Concentrates were composed from rice bran, pollard, coffee peel and molasses. The multinutrient blocks materials consisted of corn forage, urea, blood clam shells, eggshells, molasses, bentonite and salt. Randomized block design (RBD) with 4 treatments (T0: Forage + Concentrate, T1: T0 + 5g MNB, T2: T0 + 10g MNB, T3: T0 + 15g MNB) and 3 replications was used in this study. The parameters observed included daily body weight gain, dry matter and organic matter consumption and total digestible nutrients (TDN). From the results of the study it was concluded that MNB’s supplementation did not have a significant effect on dry matter T0 (1066 g), T1 (936 g), T2 (952 g) T3 (895 g), and organic matter consumption T0 (967 g), T1 (844 g) T2 (842 g), T3 (800 g), total digestible nutrients T0 (693 g), T1 (603 g), T2 (629 g), T3 (570 g) and body weight gain T0 (5 kg/head), T1 (6,2 kg/head), T2 (5,5 kg/head), T3 (5,2 kg/head) of Kacang goats. It can be suggest that multinutrient blocks should be given as a feed suplement in low quality rations to improve feed efficiency.
