Nutrients intake and fiber fraction digestibility of Kacang goats supplemented with different proportions of soybean meal and Calliandra calothyrsus in the diet

This study evaluated the use of Calliandra leaves ( Calliandra calothyrsus ) as a protein source in substituting soybean meal (SBM) in goat’s diet. Twenty female Kacang goats were used in the study.. Goats were randomly plotted into three diets treatments those were T1 = odot grass + 100% SBM; T2 = odot grass + 25% Calliandra + 75% SBM; T3 = odot grass + 50% Calliandra + 50% SBM; T4 = odot grass + 75% Calliandra + 25% SBM; and T5 = odot grass + 100% Calliandra. Grass was offerred ad libitum , whereas protein sources supplementation was based on daily protein requirements of animal. Data were collected at last 10 days of experiment, including feed intake, feed refusal, and feces. Sampels were analyzed for crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), and hemicellulose contents. Data were analyzed using one-way analysis of variance, and furtherly analyzed by Duncan’s multiple range test. Results showed that substituting of SBM with Calliandra did not have a significant effect (P>0.05) on the intakes of fiber fraction, but fiber digestibility was significantly affected (P<0.05) by treatment. The highest digestibilities of CF, NDF, and ADF were found in T1 and T2.
