Abstract

This research was to evaluate concentrate diet containing Durio zibethinus seed meal (DSM) on nutrient contents, fatty acid profiles, in vitro characteristics, and nutrients digestibility in dairy cows. The experiment was arranged in Latin Square 4 x 4 design with 4 lactating dairy cows in 4 periods in 2 weeks for each period. The treatments were diets with concentrate containing ratios of rice bran and DSM,  DC 35/12.5 (35% of Rice bran+ 12.5% of DSM), DC 27.5/20 (27.5% of Rice bran+ 20% of DSM), DC 20/27.5 (20% of Rice bran+ 27.5% of DSM) and DC 12.5/35 (12.5% of Rice bran+ 35% of DSM). Data were analyzed using analysis of variance (Anova), if any significant difference among treatment means were found, will be further analyzed using Duncan Multiple Range Test (DMRT). Results showed that 20% of  DSM supplemented in concentrate improved nutrient contents of crude protein, ether extract, medium chain fatty acid (MCFA), long chain fatty acid (LCFA), polyunsaturated fatty acid (PUFA), unsaturated fatty acid (UFA), and n6/n3. In vitro dry matter digestibility, organic matter digestibility, N-NH3, and total VFA were high in concentrate containing 35% DSM. However, in vivo digestibility evaluation showed nutrient intakes were no differences among treatments. Nutrient digestibility were found higher in diet with concentrate containing 27.5% of DSM. There were three different optimal levels could be suggested, 20% of DSM (for nutrient and fatty acid content), 27.5% of DSM (for nutrient digestibility), and 35% of DSM (for in vitro characteristics).  Supported by previous milk production, it was concluded that the 27.5% of DSM was suggested to be applied in concentrate for dairy cows.

Abstract

Sakura Block Plus is a modification of Sakura Block, incorporating 6% earthworms and palm kernel cake as substitutes for corn. The objective of this study was to evaluate the supplementation of Sakura Block Plus in palm frond feed on the nutrient digestibility of beef cattle. The research design employed a Latin Square Design (LSD) with treatments P0 (10% Sakura Block Plus), P1 (8% Sakura Block Plus), P2 (10% Sakura Block Plus), and P3 (12% Sakura Block Plus).  Four male beef cattle, 18 months old, weighing approximately ± 110 kg, were utilized throughout four treatment periods, each lasting 15 days. The results of the study indicated a significant improvement in the 12% Sakura Block Plus treatment concerning the digestibility of Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), and hemicellulose. In conclusion, the supplementation of Sakura Block Plus at the 12% level in palm frond feed resulted in the most optimal nutrient digestibility.
