Abstract

This study aims to determine the chemical quality and fermentability of the rumen contents of female Bali Timor cattle in vitro. This research used an experimental method with T-test analysis (comparative test). The number of samples for each was 15 female Timor Bali cattle as replicates, taken from two different slaughterhouses, namely Bimoku abattoir (government-owned) and Aldia Oben abattoir (privately owned). The variables observed were crude protein, crude fiber content, and concentrations of VFA and NH3. The data obtained were analyzed using a T-test (independent sample t-test) at a significance level of 5%, namely comparing the quality of the cattle rumen contents of Bimoku and Oben abbatoir. All data were processed with SPSS 25 software. The statistical analysis results of the t-test showed that the crude protein content and concentration of NH3 of the two locations was not significantly different (P> 0.05), the crude fiber content of Bimoku RPH was significantly higher (P<0.05) than RPH Oben, and VFA concentration from RPH Oben was significantly (P<0.05) higher than Bimoku RPH. It was concluded that differences in abattoir management before slaughtering affected the quality of the rumen contents of female Timor Bali cattle

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.
