Abstract

This study was conducted to investigate the effects of supplementing Pueraria phaseoloides on feed intake, nutrient digestibility, rumen fermentation, and blood profiles in male Kacang goats fed Kume grass hay as a basal diet. Twelve male Kacang goats aged between 6 and 8 months with a mean body weight of 13.63 ± 1.40 kg were randomly assigned to four dietary treatments (three goats per treatment) in a 3x4 incomplete Latin square design. The treatments consist of a control group (P0) receiving grass hay and concentrate and three groups supplemented with 10% (P10), 20% (P20), and 30% (P30) P. phaseoloides of protein requirement on a dry matter basis. The data obtained in this study were statistically analyzed using the GLM procedure following ANOVA in SPSS Statistics for Windows, version 22. The results indicated that P. phaseoloides significantly (p<0.05) increased feed intake, with goats receiving P. phaseoloides consuming more dry matter compared to the control group (P0). Furthermore, nutrient digestibility improved (p<0.05) with P. phaseoloides supplementation. However, rumen fermentation characteristics, including NH3-N concentration, VFA concentration, and ruminal pH, did not differ significantly among the dietary treatments. Additionally, there were no significant differences in blood profiles among the Kacang goats under different dietary treatments. In conclusion, supplementation of P. phaseoloides in male Kacang goats fed Kume grass hay as a basal diet improved feed intake and nutrient digestibility but had no significant effect on rumen fermentation or blood profiles. Therefore, P. phaseoloides can be used as a feed supplement for ruminants consuming low-quality grass.

Abstract

The objective of this metabolism study was to evaluate the efficacy of Siam weed (Chromolaena odorata) meal in pelleted diets for fattened cattle. Four 2-year-old Bali steers were assigned to four dietary treatments using a 4x4 Latin square experimental design. The treatments were pellets containing chromolaena meal at 10% (10COM), 20% (20COM), 30% (30COM), or 40% (40COM). The pellet was given at 2% liveweight (LW), and kume (Sorghum plumosum var. Timorense) grass hay was offered ad libitum. The diets were isonitrogenous (20%) and energy (11.5 MJ ME/kg DM). Dietary intake, digestibility, and rumen fermentation were the variables measured. The results showed that increasing chromolaena meal to 40% substantially decreased the nutrient intake. Dry matter intake decreased from 2.5% LW in the 10COM to 2.19% LW in the 40COM. Likewise, crude protein intake decreased from 749 g/d (10COM) to 661 g/d (40COM). On the contrary, digestibility, rumen pH, ammonia concentration (116–125 mg/dL), and volatile fatty acids were not affected. It might be concluded that chromolaena can be used as a protein source for ruminants, but at high levels of inclusion (40%) tends to reduce intake.

Abstract

This study aimed to enhance nutrient intake, digestibility, rumen fermentation, and blood metabolites in Kacang goats by substituting grass silage with hydroponic maize fodder enriched with fermented compost tea. The compost tea, prepared by fermenting organic compost with sugared water + 40 mL EM4 for 3 days, was used to grow maize fodder hydroponically. Four male Kacang goats (13.05 ± 1.32 kg) were assigned to four dietary treatments in a 4x4 latin square design over four 15-day periods (10 days for adaption, 5 days for data collection). The treatments were: 60% grass silage + 10% Leucaena leucocephala + 30% concentrate (control, FCG0); 30% grass silage + 30% hydroponic maize fodder + 10% L. leucocephala + 30% concentrate (FCG1); 15% grass silage + 45% hydroponic maize fodder + 10% L. leucocephala + 30% concentrate (FCG2); and 60% hydroponic maize fodder + 10% L. leucocephala + 30% concentrate (FCG3). Goats on FCG3 had lower (p<0.05) dry matter intake (152.48 g/day) compared to FCG0 (226.83 g/day). Nutrient digestibility, including organic matter and crude fiber, improved (p<0.05) in FCG3 (77.21% and 66.12%) compared to FCG0 (76.62% and 52.27%). Total volatile fatty acids (VFA) increased in FCG3 (131.54 mM) compared to FCG0 (111.73 mM). However, no significant differences were observed in ruminal ammonia (NH₃-N), ruminal pH, or blood metabolites. In conclusion, substituting grass silage with hydroponic maize fodder enriched with fermented compost tea up to 75% of the diet improved digestibility and rumen fermentation without negatively affecting intake, digestibility, or blood metabolites in Kacang goats, suggesting its potential as an alternative feed. However, complete substitution (100%) reduced intake, indicating challenges at higher substitution levels.
