某奶牛场全混合日粮技术饲喂效果

Effectof Total Mixed Diet Technology on Feeding Cow in a Dairy Farm

全混合日粮(TMR)是现代标准化、规模化奶牛场普遍采用的饲喂技术。该技术是依据奶牛各阶段的营养需要,一次性供给奶牛精粗比合适、适口性较好、各部分营养浓度相同的日粮。[目的]为了定量分析TMR技术效果。[方法]采用全混合日粮技术饲喂奶牛。[结果]产奶牛奶量提高了10.8%,干物质、蛋白质、脂肪含量分别提高了1.6%,3.9%和4.6%,每头产奶牛日均增加效益10.7元。[结论]应用全混合日粮饲养技术可以提高产奶量、乳品质以及经济效益。

[Objective] Total mixed ration (TMR) is a feeding technique commonly used in modern, standardized, large-scale dairy farms. Based on the nutritional needs of the cows at various stages, this technology provides a one-time diet for cow that has the appropriate ratios of concentrated feed and roughage, good palatability, and the same nutritional concentration of each part.[Method] The TMR was used to feed cow.[Result] The milk output increased by 10.8%, and the dry matter, protein, and fat content increased by 1.6%, 3.9% and 4.6%, respectively. The average daily benefit per cow increased by 10.7 yuan.[Conclusion] The results showed that TMR can improve milk yield, milk quality and economic benefits.
