摘要: 沼泽红假单胞菌和地衣芽胞杆菌可调节动物消化系统的微生态环境,为宿主提供优质的营养物质及多种利于消化功能的生物活性酶。以泌乳末期荷斯坦奶牛为实验动物,探究沼泽红假单胞菌和地衣芽胞杆菌对奶牛采食量、产奶量和发病情况等生产性能指标的影响。结果表明:在奶牛全混合日粮(TMR)中添加沼泽红假单胞菌和地衣芽胞杆菌可以显著提升奶牛生产性能,日采食量下降8.05%,日产奶量显著提高5.42%(P<0.05),饲料转化率提高14.70%,同时,奶牛消化水平和健康状况也得到明显改善。

Abstract: Rhodopseudomonas palustris and Bacillus licheniformis can regulate the micro-ecological environment of the animal's digestive system, and provide the host with high-quality nutrients and a variety of bioactive enzymes that are beneficial to digestive function. In this study, the dairy cows were used as experimental animals to assess the impacts of dietary supplementation of Rhodopseudomonas palustris and Bacillus licheniformis on their feed intake, milk yield and healthy status. The results showed that the addition of Rhodopseudomonas palustris and Bacillus licheniformis in total mixed ration (TMR) significantly improved the production performance of dairy cows; compared to the control group, the daily feed intake of the experimental group was reduced by 8. 05%, the daily milk yield was significantly elevated by 5. 42% (P<0. 05), and the feed conversion rate was increased by 14. 70%. Furthermore, the digestive level and health status of the dairy cows in experimental group was also improved obviously.

Key words: Rhodopseudomonas palustris, Bacillus licheniformis, production performance, feed intake, milk yield
