摘要
In order to investigate the effect of the plane of nutrition on intake and nutrient utilization from urea molasses mineral blocks (UMMB) and rumen fermentation pattern, sixteen adult crossbred cattle were divided into four equal groups following a completely randomised design and fed individually for 60 days ad libitum with either wheat straw alone (Group I) or with wheat straw with UMMB (Group II) or with wheat straw and UMMB with 50% of energy requirements provided by crushed barley fortified with mineral mixture and common salt (Group III) or with wheat straw and UMMB with 100% of energy requirements provided by fortified crushed barley (Group IV). At the termination of the feeding trial, a metabolism trial of six days duration was also conducted. A fermentation study was carried out on four rumen fistulated adult cattle following a 4 × 4 latin square design. Results showed that intake (except for ether extract) and digestibility of all the nutrients increased significantly (P P

为了研究营养面对尿素糖蜜矿物质块（UMMB）和瘤胃发酵模式的摄入和养分利用的影响，将16头成年杂种牛按照完全随机设计分成四个相同的组，并单独喂养60天（III组）或小麦秸秆与UMMB（II组）或小麦秸秆和UMMB（用强化矿物质混合物和食盐（III组）的碎大麦提供的能量需要量）或与小麦秸秆和UMMB，由强化碎米提供100％的能量需求（第IV组）。在饲养试验结束时，还进行了6天的代谢试验。以4×4拉丁方设计对4头瘤胃成年的成年牛进行发酵研究。结果显示，所有营养素的摄入量（乙醚提取物除外）和消化率均显着增加（P 0.05）
