Additive for improving dry matter intake of dairy cow feed in early lactation

Abstract

The invention discloses an additive for improving the dry matter intake of dairy cow feed in early lactation and relates to the additive for improving the dry matter intake of the dairy cow feed. The additive can solve the problems that the existing various phagostimulants, feed physiological regulating agents for promoting appetite and other artificial chemical synthetic preparations have highercost, residues in milk are easy to affect digestion and metabolism of ingredients and the like. The product comprises the following components in parts by weight: 8-10 parts of membranous milkvetch root, 8-10 parts of pilose Asiabell root, 8-9 parts of liquoric root, 6-7 parts of uniflower swisscentaury root, 5-6 parts of Chinese angelica, 5-6 parts of motherwort herb, 5-6 parts of acorn powder, 5-6 parts of tangerine peel, 5-6 parts of peppermint, 5-6 parts of Mongolian dandelion herb, 5-6 parts of parslane herb and 5-6 parts of Chinese magnoliavine fruit, is obtained by drying, crushing andscreening, and can be used for direct feeding after stirring uniformly, essentially condition the physiological functions of dairy cows in the early lactation, improve the dry matter intake of the feed and the milk yield, have no residue in the milk, improve the reproductive performance, further effectively reduce the occurrence of nutrition and metabolism disorder diseases and prolong the service years of the dairy cows.

Description

technical field [0001] The invention relates to an additive for increasing dry matter intake of dairy cow feed. Background technique [0002] A large number of studies have confirmed that in each period of lactation of dairy cows, the milk production in the early lactation period (100 days after delivery) can account for about 40%-50% of the production in the entire lactation period. The yield level of dairy cows will be reduced by 200-250kg, therefore, the pre-lactation period is the most important period to realize the lactation potential of dairy cows. Feed dry matter intake is the key to determine the lactation volume of dairy cows. During the early lactation period, dairy cows undergo childbirth and blood loss, and their body resistance and digestive function are weakened. Poor appetite and slow increase in feed dry matter intake lead to a serious lack of nutrient intake by dairy cows. The direct consequence is a decrease in milk production, and dairy cows are prone to...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of the relatively high cost of artificial chemical synthesis preparations such as various food attractants and appetite-stimulating physiological regulators to improve the dry matter intake of dairy cow feed in the early lactation period, and the residues in the milk are easy to affect nutrients. Provide an additive to increase the dry matter intake of dairy cow feed in the early lactation period to solve the problems of digestion and metabolism
