| Description | Rumen fermentation curves were obtained for sheep fed four silages of different quality. Peak levels of volatile fatty acids (VFA) and ammonia were reached within one hour of the start of feeding. Protein nitrogen (PN) levels fell after feeding as in grass-fed sheep. In another series of trials, rumen samples were taken two hours after feeding from ten groups of sheep fed ten silages of different compositions. Ruminal pH and VFA levels were constant irrespective of silage pH, VF A, and lactic acid content. Ruminal ammonia levels were related more to silage ammonia and residual nitrogen (RN) levels combined than to either level separately. Ruminal PN levels were low and RN levels high on all silages. It is suggested that levels of rumen end-products are dependent more on the combined soluble constituents, bacterial products plus grass solubles, than on individual constituents or digestibility of the silage. |
