Abstract
Incubations were carried out with batch cultures to study the effects of different nitrogen (N) sources on in vitro fermentation by ruminal micro-organisms of two substrates of variable fermentation rate. The substrates were composed by starch and cellulose in proportions of 75:25 (starch) or 25:75 (cellulose). Three treatments were made by replacing ammonia-N (NH4Cl) with purified soyabean protein (SP) at levels of 0 (NNP), 50% (S50) and 100% (S100) of total N. Compared with NNP, S50 and S100 treatments increased CH4 production by 51.0 and 50.6% for starch and by 7.7 and 29.7% for cellulose substrates, respectively. The increases in volatile fatty acids (VFA) production were 4.4 and 6.3% for starch and 33.1 and 58.9% for cellulose substrates, respectively. These results indicate that the influence of N source on CH4 and VFA production are influenced by the characteristics of the incubated substrate
