| 摘 要： | 奶牛饲粮物理有效中性洗涤纤维对于维持奶牛最佳瘤胃功能、减少代谢失调发生、预防生产性能下降等具有重要作用。奶牛瘤胃可降解淀粉含量与谷物类型、谷物加工处理方法、奶牛瘤网胃中食糜流通速率有很大关系。本文主要就奶牛饲粮物理有效中性洗涤纤维和瘤胃可降解淀粉的平衡关系及其对奶牛瘤胃液pH和生产性能的影响做一综述,以期为生产实践提供理论依据。

| Abstract: | Dietary physically effective neutral detergent fiber(peNDF) is critical in maintaining rumen function,decreasing the risk of metabolic disorders and preventing the decrease of performance of dairy cows.Rumen degradable starch(RDS) content is related to the type and processing method of grain,as well as the passage rate of digesta from the reticulo-rumen.In order to provide a theoretical guidance for production,balance between dietary peNDF and RDS and its effects on rumen fluid pH and performance of dairy cows are reviewed in this paper. |
