【摘要】：近年来,奶牛养殖业迅猛发展,而犊牛培育是其健康稳定发展的关键因素之一。寻求最佳的饲料饲喂水平促进犊牛健康快速的生长是极为重要的。犊牛饲料包括固体饲料和液体饲料,是犊牛饲喂的根本,其中液体饲料包括初乳、牛奶、代乳粉等;固体饲料则包括开食料和不同饲草等。固液饲料平稳过渡是犊牛饲喂成功的关键,也是多年来专家学者研究的重点。另外,断奶日龄与固液饲料饲喂水平紧密相关,也是犊牛饲喂模式中的重要指标。本文阐述了犊牛固液饲料饲喂水平与其采食量间的相互关系,总结了固液饲料饲喂水平及断奶日龄对犊牛瘤胃发育、生长性能的影响,提出了在犊牛饲喂模式中仍然需要探索的问题。希望能够找到犊牛饲喂领域所急需的固液饲料饲喂水平与断奶日龄相结合的最适宜的饲喂模式,促进犊牛生长发育,为后期充分发挥生产性能打下良好的基础,进而提高养牛行业的经济效益。
[Abstract]:In recent years, the dairy cattle breeding industry has developed rapidly. Calf breeding is one of the key factors for the healthy and stable development of calves. It is very important to seek the best feed level to promote the healthy and rapid growth of calves. Calves feed, including solid feed and liquid feed, is the root of calves feeding. Among them, liquid feed includes colostrum, milk, milk powder, etc. Solid feed includes open feed and different forage, etc. The smooth transition of solid feed is the key to the success of calf feeding, and is also the focus of many years of research by experts and scholars. The age of weaning is closely related to the level of solid feed feeding, and it is also an important index in the feeding mode of calves. The relationship between the level of solid feed feeding and the feed intake of calves is described in this paper. The effects of solid feed level and weaning age on rumen development and growth performance of calves were summarized. The problems still need to be explored in the feeding mode of calves are put forward. It is hoped to find the most suitable feeding mode which combines the level of solid feed feeding with the age of weaning, which is badly needed in the field of calves feeding, so as to promote the growth and development of calves. It lays a good foundation for giving full play to the production performance in the later stage, and then improves the economic benefit of the cattle raising industry.
