| Popis: | The study aimed to predict the concentration on cattle’s enteric methane fed with different crude fibre (CF) content. Twenty-four male Bali cattle were fed with three different rations of A (low CF), B (medium CF) and C (high CF). At the end of the study, the rumen fluid was taken at 0 and 3 h after feeding, analysed for partial VFA to predict the concentration of enteric methane formed. The experiment design was a completed randomized design with three treatments and eight replications. Prediction of methane concentration at 0 and 3 h and their increase were not differed among treatments. At 0 h, the predicted methane concentrations of treatments A, B and C (mean ± SEM) were 12.59 ± 0.561 mmol L−1, 9.53 ± 1.737 mmol L−1 and 9.06 ± 1.041 mmol L−1, respectively. While at the 3 h were 16.64 ± 1.19 mmol L−1, 14.2 ± 1.052 mmol L−1 and 16.24 ± 1.495 mmol L−1, respectively. The increasing methane concentration up to 3 h was 42.74 ± 16.895%, 79.39 ± 16.332% and 58.00 ± 11.120%. It was concluded that the difference in fibre ration content had not affected the concentration of methane up to 3 h after feeding. |
