Biological feed additive for improving reproductive performance of herbivorous female animal

Abstract

The invention discloses a biological feed additive for improving the reproductive performance of a herbivorous female animal. The biological feed additive is prepared from (1) a yeast culture or an active dry yeast, (2) rumen protected choline, (3) a lactic acid bacteria preparation, (4) a complex enzyme, (5) glucose oxidase, (6) vitamin E powder, (7) a beta-carotene preparation or carrot residues and (8) a diluent. In fine feed in the perinatal period and the early-lactation period (from 21 days before the due date to 90 days after delivery), by adding the biological feed additive, the dry material feed intake in the later period of the perinatal period of the herbivorous female animal can be obviously improved, and the reproductive performance and health level of the herbivorous female animal are improved.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a biological feed additive for improving the reproductive performance of herbivorous female animals. Background technique [0002] Since the outbreak of African swine fever in 2018, the risk of the epidemic has led many farmers and related companies to turn to the cattle industry. There is a direct relationship between the reproductive performance of dairy and beef cattle and its production level. A high reproductive rate is the key to ensure the final milk production of dairy cows, the growth of beef cattle population and economic benefits. This requires the cows to be healthy and capable of calving year after year. However, at present, family pastures or large-scale farms have serious problems such as long calving intervals and nutritional and metabolic diseases, which cannot meet the requirement of one calving a year, seriously affecting production performance. Therefore, impr...

Problems solved by technology

[0005] Aiming at the problem of low reproductive performance of cows in my country and the shortage of existing cow biological feed additives, the present invention provides a new technical solution, which intends to supplement functional essential nutrients, nourish the stomach, promote digestion, resist oxidation, and regulate fat Metabolism and reduction of mycotoxin hazards and other measures to improve the negative energy balance of cows during the peripartum and early lactation period, control metabolic diseases, relieve labor stress, and improve cow reproductive performance
