Concentrate supplementary feed for high yield period of cow and preparation method for concentrate supplementary feed

Abstract

The invention relates to the technical field of feeds, and particularly discloses a concentrate supplementary feed for a high yield period of a cow and a preparation method for the concentrate supplementary feed. The supplementary feed is prepared from the following raw materials in percentage by weight: 38 to 42 percent of corn, 1 to 2 percent of molasses, 8 to 12 percent of soybean meal, 5 to 10 percent of cottonseed meal, 2 to 5 percent of bran, 3 to 8 percent of DDGS feed, 0.5 to 2 percent of wheat middling, 1 to 3 percent of corn gluten meal, 5 to 10 percent of corn germ meal, 10 to 15 percent of sprayed corn husk, 0.05 to 0.2 percent of a mould removal agent, 0.03 to 0.1 percent of enterococcus faecalis, 0.3 to 0.8 percent of table salt, 1.0 to 2.0 percent of baking soda, and 5.0 percent of cow premix. The raw materials of the supplementary feed are matched reasonably in the range of limited using amount, cooperate with one another, and provide nutrient elements required by the cow in the high yield period; the amino acid composition is reasonable, and the mild yield of the cow, the milk protein content and the butter-fat content are increased. The preparation method provided by the invention is easy to operate, and applicable to popularization and application.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a concentrate supplement for high-yield dairy cows and a preparation method thereof. Background technique [0002] In recent years, with the continuous and stable development of China's economy and the improvement of per capita living standards, the country and localities have listed the dairy industry as a prominent industry. In recent years, the size of the domestic dairy market has increased substantially. From 2000 to 2005, milk production increased by 211.7%. However, compared with developed countries, the overall development level of my country's dairy industry is not high. According to the analysis of authoritative organizations, the per capita consumption of urban residents in my country is only about 20 kilograms per year, which is 1 / 5 of the world average level, while the per capita annual consumption of developed countries reaches 320 kilograms, which is 16 times that of ...

Problems solved by technology

Wherein in the process of raising dairy cows, the nutrient level of the concentrate supplementary material during the milk production period of the dairy cow directly affects the milk production performance such as the milk yield of the dairy cow and the milk fat rate and milk protein of the original milk. In the prior art, in the concentrate supplementary material Add the report of using yeast culture to improve the milk production of dairy cows and lactose and milk fat content in milk, but the feeding amount of yeast culture is large, the cost is high, and for the milk production of dairy cows and the improvement effect of lactose and milk fat content in milk. limited

Generally speaking, the traditional concentrate supplements for dairy cows are not suitable for the nutritional needs of high-yielding dairy cows, and the milk produced by dairy cows has a low milk fat percentage and low milk protein. Concentrate supplements for milk quality have become an urgent problem in the current dairy industry
