Abstract

This study aimed to analyze the economic value of cull female Bali cattle at different ages in Kupang Regency. A total of 40 cows were grouped into young (2-4 years), medium (4–7 years), and old (7–10 years). Economic parameters measured included live animal value, carcass value, non-carcass value, and added value using the Hayami method. Data were analyzed using ANOVA followed by Duncan’s test. The results showed that age significantly affected the proportion of non-carcass components (P<0.05), but not slaughter weight and carcass percentage. However, the economic value of live animals, carcass, non-carcass, and slaughtering added value increased with age. Older cows generated higher economic returns, although carcass efficiency was relatively constant across age groups. It can be concluded that culling age influences economic value, and the carcass-based selling system (carcass weight) provides more accurate and profitable returns than live weight transactions.

Abstract

This study aimed to investigate the effect of substituting Kume Grass hay with maize fodder hay on the feeding behavior of Kacang Goats. Eight goats weighing 10–15 kg were used in a change-over design with four treatments and two periods as replicates. The treatments were: DMF0 (70% Kume Grass hay + 30% concentrate), DMF1 (52.5% Kume Grass hay + 17.5% maize fodder hay + 30% concentrate), DMF2 (35% Kume Grass hay + 35% maize fodder hay + 30% concentrate), and DMF3 (17.5% Kume Grass hay + 52.5% maize fodder hay + 30% concentrate). Data were analyzed using ANOVA followed by Duncan’s multiple range test. Results showed that feeding time ranged from 4.5 to 7.0 hours/day, eating frequency from 6.3 to 12.8 times/day, rumination time from 3.6 to 5.1 hours/day, rumination frequency from 10.1 to 19.6 times/day, resting time from 13.1 to 14.5 hours/day, and resting frequency from 17.1 to 21.8 times/day. Statistical analysis revealed that the treatments significantly (P<0.05) affected feeding time, eating frequency, and resting frequency, but had no significant effect (P>0.05) on rumination time, rumination frequency, and resting time. In conclusion the substitution of Kume Grass hay with maize fodder hay up to 75% the eating duration, eating frequency and resting frequency, but it does not affect the rumination duration, rumination frequency and resting duration.
