Feed additive for improving pregnant sow reproductive performance and preparing method thereof

Abstract

The invention relates to a feed additive for improving pregnant sow reproductive performance and a preparing method thereof. The additive comprises traditional Chinese medicine composite components and N-carbamylglutamic acid. The weight ratio of the traditional Chinese medicine composite components and the N-carbamylglutamic acid is (20-30) : 3. The traditional Chinese medicine composite components comprise the components of, by weight, 10-30 parts of cortex magnoliae officinalis, 10-25 parts of immature bitter orange, 2-10 parts of mirabilite, 6-24 parts of raw rhubarb, 8-20 parts of radix paeoniae alba, 10-20 parts of rhizoma sparganic, 5-15 parts of curcuma zedoary, 5-15 parts of scutellaria baicalensis, 10-50 parts of dandelions and 5-15 parts of raw betel nuts. Compared with the prior art, nuisanceless natural Chinese herbal medicine is used, chemical synthesis antibacterial agents and toxic and harmful substances are not added at all, the preparing method is simple, the medicine absorbing degree and the bioavailability are high, preparing cost is low, sow gastrointestinal tracts are effectively nursed, constipation is avoided, the problems of sow intrauterine growth retardation and pregnancy early trimester placenta development and function limiting can be effectively solved, and then pregnant sow reproductive performance is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of feed additives and relates to a feed additive, in particular to a feed additive for improving the reproductive performance of pregnant sows and a preparation method thereof. Background technique [0002] According to the data from the Department of Animal Husbandry of the Ministry of Agriculture, at the end of 2013, the number of fertile sows in China was about 49 million, and about 690 million pigs were slaughtered annually. Based on this data, each sow in China provides about 14 commercial pigs per year on average ( MSY), the main reason for this result is that the number of weaned piglets (PSY) provided by each sow per year is small, and PSY is the most important indicator to measure the reproductive performance of sows, which directly affects the economic benefits of large-scale pig farms. He Lang (2012) sorted out and counted the production data of 2,790 parities of sows from 2 large-scale pig farms ...

Problems solved by technology

The technical scheme published in this patent is mainly to maintain the health of sows through the coordination and linkage of the drug effects of various components. Direct mixing with vitamin A, vitamin E and folic acid may affect the absorption and utilization of vitamins by the body of sows, and the ingredients of Chinese herbal medicine are relatively single, and the actual effect is limited, so further improvement is needed
