Functional pellet feed for high yield cows in lactation period

Abstract

The invention relates to a functional pellet feed for high yield cows in the lactation period, which comprises the following components: 13-23% of corns, 1-10% of palm kernel meal, 15-25% of corn fiber, 17-27% of corn germ meal, 8-18% of barley, 8-18% of wheat, 2-12% of bean meal, 1-10% of corn DDGS (Distillers Dried Grains with Soluble), 1-10% of puffed beans, 1-2% of limestone powder, 1-5% of cotton seed meal, 1-8% of double-low rapeseed meal, 0.5-2.5% of glucose powder, 1-5% of liquid molasses, 0.3-1% of table salt, 0.5-3% of saturated fat powder and 0.5-1.5% of compound premix for cows. In the invention, energy liberation and proteolysis are synchronously controlled, and the functional pellet feed has important significance in increasing solid feed intake in summer, increasing milk yield, improving milk quality, increasing postpartum conception rate and reducing the incidence of incidence.

Description

technical field [0001] The invention relates to a dairy cow feed, in particular to a high-yield dairy cow lactation functional granular feed for improving and improving the production performance of dairy cows during the lactation period, and belongs to the technical field of feed compositions. Background technique [0002] In the past ten years, my country's dairy farming industry has begun to transform from a quantity growth model to a quality benefit model, from blind breeding to the pursuit of production efficiency. The benefits of dairy farming can be improved by increasing the unit milk yield and milk quality of dairy cows. The ensuing question is how to achieve high-level lactation of dairy cows by improving dietary nutrition and disease control. Due to the specificity of the dairy cow’s diet structure, the difference in the roughage level, and the long production cycle of the dairy cow, they face various stresses every year, especially the heat stress in summer, whi...

Problems solved by technology

Due to the specificity of the dairy cow’s diet structure, the difference in the roughage level, and the long production cycle of the dairy cow, they face various stresses every year, especially the heat stress in summer, which leads to a serious shortage of dry matter intake of dairy cows. In actual production There are often a series of problems such as short lactation peak duration, poor milk quality, low reproductive conception rate, and high incidence of ketosis, which greatly affect and limit the production capacity of dairy cows.

[0003] In China, for high-yielding dairy cows, most of the roughage they eat is various crop stalks, which have low digestibility and poor nutritional level, which are far from meeting the rumen microbial nutrition of dairy cows and the nutritional needs of lactating cows themselves. Supplementary feeds provide needed nutrients to make up for deficiencies in the nutritional level of the overall diet

Research results at home and abroad show that simply increasing the crude protein content of the diet cannot fundamentally solve the problems of short lactation duration and poor milk quality. Improving the internal environment of the rumen is the key
