Abstract

This research aims to examine the correlation between digestible crude protein (DCP) and digestible crude fiber (DCF) on methane gas production from fermented rice straw using urea and urine. The material in this study was used included eight indigenous rams aged ± 1.5 years with a weight of ± 20 kg. The feed provided consisted of concentrate and rice straw fermented with urea (P1) and rice straw fermented with urine (P2). Feed was given twice daily, and water was provided ad libitum. Data collection of digestible crude protein and digestible crude fiber was conducted by total collection method in metabolic cages for 7 days, while methane gas production measurement was conducted for 2 x 24 hours. The results showed differences in correlation values between the two types of treatments. Treatment with rice straw fermented with urea had correlation values of 0.937 for digestible crude protein and 0.507 for digestible crude fiber with coefficient of determination values of 87.9% for DCP and 25.7% for DCF. Meanwhile, in the treatment with rice straw fermented with urine, the correlation values were -0.632 for DCP and -0.991 for DCF with coefficient of determination values of 40.0% for DCP and 98.3% for DCF. The conclusion from this research is that the difference in correlation values is caused by the nitrogen source used for fermentation and the presence of accompanying compounds found in cattle urine used for rice straw fermentation.

Abstract

Objective: This research aimed to find out the VFAs profile and methane gas production in fat-tailed sheep that fed rice straw ammoniated with commercial urea (T1), and rice straw ammoniated with urine (T2). Eight thin-tailed sheep aged 1.5 with an average body weight of 20 kg were used in this study. All the object studies were placed in individual metabolism cages. The feed concentrate used in this study was 2.3 % from the body weight of livestock, rice straw was ammoniated and water was given ad libitum, and feed was given twice a day at 7.00 a.m. and 4.00 p.m. Concentrate were given first, then 1 hour later the ammoniated rice straw was given. The drinking water was provided ad libitum.Methods: This research was conducted in three stages, 1) total collection, 2) measure methane gas production, and 3) rumen fluid collection. A completely randomized design with 2 treatments and 4 replications was used in this study. After all data was collected, then it was analyzed using the Independent T-test using IBM SPSS Statistics 21 software.Results: The results show no significance (P > 0.05) on rice straw ammoniated with commercial urea (T1), and rice straw ammoniated with urine (T2) for methane gas production (1,328.68±349.56 vs 1,463.95±215.41), VFA Total (40.74±13.09 vs 34.79±6.34), NH3 production (9.17±3.67 vs 8.78±2.94). It indicates that ammoniated using commercial urea or urine does not interrupt rumen fermentation.Conclusions: It could be concluded that crude protein digestible, methane gas production, and VFAs profile especially the fermentation conditions in the rumen are not affected by ammoniation from commercial urea or urine.
