With the increase in the global buffalo herd, the use of supplementation in the ruminant feeding has become an important area for many researchers who are looking for an isocaloric and isonitrogenous diet to improve production parameters. In order to improve the performance of the Asian water buffalo, the optimal balance of all nutrients, including energy and protein, are important as macronutrients. Dietary supplementation is one of the alternatives to enhance the essential nutrient content in the buffalo diet and to improve the rumen metabolism of the animal. Researchers have found that supplementation of concentrate and rumen bypass fat could change growth performance and carcass traits without causing any adverse effects on the buffalo growth. Some studies showed that dry matter intake, body condition score and some blood parameters and hormones related to growth responded positively to concentrate and rumen bypass fat supplementation. In addition, changes of feeding management by adding the supplement to the ruminant basal diet helped to increase the profit of the local farmers due to the increased performance and productivity of the animals. Nevertheless, the effects of dietary supplementation on the performance of ruminants are inconsistent. Thus, its long-term effects on the health and productivity of buffaloes still need to be further investigated.
随着全球水牛数量的增加，在反刍动物饲养中使用补充饲料已成为许多研究人员关注的重要领域，他们正在寻找一种等热量和等氮量的日粮来改善生产参数。为了提高亚洲水牛的生产性能，包括能量和蛋白质在内的所有营养素的最佳平衡作为常量营养素至关重要。日粮补充是提高水牛日粮中必需营养素含量和改善动物瘤胃代谢的一种选择。研究人员发现，补充精饲料和瘤胃旁路脂肪可以改变生长性能和胴体性状，而不会对水牛生长造成任何不利影响。一些研究表明，干物质摄入量、体况评分以及一些与生长相关的血液参数和激素对精饲料和瘤胃旁路脂肪补充有积极反应。此外，通过在反刍动物基础日粮中添加补充剂来改变饲养管理，由于动物生产性能和生产力的提高，有助于增加当地农民的利润。然而，日粮补充对反刍动物生产性能的影响并不一致。因此，其对水牛健康和生产力的长期影响仍需进一步研究。
