摘要
Quebracho (Loxopterygium loetzil)单宁(QT)是一种缩合单宁，可以降低反刍动物对营养物质的消化率(Robbins, et al .， 1991)，可能是通过与膳食中的蛋白质和碳水化合物形成复合物，从而降低微生物的活性(Makkar, et al .， 1988)。聚乙二醇(PEG)的商业制剂Browse Plus (BP)最近被用于提高含有单宁的Browse的营养价值。在津巴布韦的商业农场进行的试验表明，BP改善了饲喂高单宁饲料的牛的营养性能(Anon, 1995)。一些体外研究倾向于支持这些发现(Acamovic, et al, 1995)。本试验旨在研究BP对QT对瘤胃环境影响的改善作用。
The utilisation of a commercial polyethylene glycol preparation to ameliorate the influence of tannins on rumen environment
Quebracho (Loxopterygium loetzil) tannins (QT) are condensed tannins that reduce the digestibilities of nutrients in ruminants (Robbins, et al, 1991), probably by forming complexes with the dietary protein and carbohydrates and reducing microbial activities (Makkar, et al, 1988). Browse Plus (BP), a commercial preparation of polyethylene glycol (PEG) has recently been used to improve the nutritive value of tannin-containing browses. Trials on commercial farms in Zimbabwe have demonstrated that BP improved the nutritional performance of cattle fed high tannin diets (Anon., 1995). Some in vitro work tend to support these findings (Acamovic, et al, 1995). An experiment to study the effectiveness of BP in ameliorating the effects of QT on the rumen environment was conducted.
