Supplemental nitrate is known to be an effective tool to mitigate methane emission by ruminants. Based on theoretical considerations, supplemental nitrate can improve but also deteriorate the growth performance. The overall effect of supplemental nitrate on growth performance, however, is not yet known. The objective of the current study was therefore to evaluate the effect of a higher dose of NO3- on overall growth performance when feeding either Pangola grass hay or rice straw.

基于稻草而不是Pangola干草的口粮中的硝酸盐补充可以改善肉山羊的生长性能。

已知补充硝酸盐是减轻反刍动物甲烷排放的有效工具。基于理论上的考虑，补充硝酸盐不仅可以改善生长性能，而且会降低其生长性能。但是，补充硝酸盐对生长性能的总体影响尚不清楚。因此，本研究的目的是评估饲喂Pangola草干草或稻草时，较高剂量的NO3-对总体生长性能的影响。
