Feed additive for solving breeding pig reproductive disturbance as well as preparation and application thereof

Abstract

The invention discloses a feed additive for solving breeding pig reproductive disturbance as well as a preparation and an application thereof, and belongs to the field of feed additives. The feed additive for solving the sow reproductive disturbance is mainly prepared from the following components: vitamin D3, vitamin E, folic acid, D-biotin, nicotinamide, D-calcium pantothenate, 25-hydroxy vitamin D3, vitamin C, beta-carotene, L-carnitine, chromium picolinate, selenium yeast, zinc glycinate, iron glycinate and saccharomyces cerevisiae hydrolysate. The feed additive for solving the breeding pig reproductive disturbance is mainly used for solving the reproductive disturbance problems of poor milk, unsmooth oestrus, small litter size and large hoof crack of the sows, and poor sexual desire,small semen volume, low sperm motility and the like of boars.

Description

technical field [0001] The invention belongs to the field of feed additives, and relates to a feed additive for solving reproductive obstacles of breeding pigs and its preparation and application. Background technique [0002] In recent years, with the vigorous development of my country's pig industry and the continuous improvement of intensification and scale, breeding pigs often show: slow estrus, false estrus, high rate of return to estrus, small sow litter size, newborn weight Small size, poor uniformity, less postpartum milk, poor milk quality, low libido, reduced semen collection, low effective sperm density, high sperm deformity rate and other reproductive obstacles are becoming more and more serious, and have become the influence and restriction of pig breeding The bottleneck of production efficiency seriously affects the economic benefits of farming and the enthusiasm of farmers. [0003] There are multiple factors that cause breeding disorders in breeding pigs, but ...

[0002] In recent years, with the vigorous development of my country's pig industry and the continuous improvement of intensification and scale, breeding pigs often show: slow estrus, false estrus, high rate of return to estrus, small sow litter size, newborn weight Small size, poor uniformity, less postpartum milk, poor milk quality, low libido, reduced semen collection, low effective sperm density, high sperm deformity rate and other reproductive obstacles are becoming more and more serious, and have become the influence and restriction of pig breeding The bottleneck of production efficiency seriously affects the economic benefits of farming and the enthusiasm of farmers

[0003] There are multiple factors that cause breeding disorders in breeding pigs, but nutrition is a very important factor, because feed nutrition can regulate the secretion of various reproductive hormones and affect the normal reproductive function of breeding pigs

At present, feed nutrition, especially trace nutrition, cannot meet the breeding needs of breeding pigs, and there are reproductive obstacles. The reasons are summarized in five points: 1. The feeding management conditions of the designed feed formula are very different from the on-site feed management, such as feed intake, temperature, humidity, Drinking water, feed mildew, pig health status, parity and many other factors; 2. Farmers have higher and higher requirements for pig production performance and nutrition; 3. The development of genetic breeding , forcing the need for higher nutrition to exert higher production performance; 4. The feed regulations stipulate the limited amount of some vitamins in the feed. When breeding problems occur in breeding pigs, the demand for vitamins such as vitamin E should be increased; Nutrients closely related to pig breeding such as β-carotene and 25-hydroxyvitamin D 3 , L-carnitine and other vitamins are not added or rarely added to the feed, but they are of great significance to the reproduction of sows

A special feed additive for breeding pigs has been developed, which is used to solve the problems of poor milk, bad estrus, small litter size, many cleft hooves, poor libido, low semen volume and low sperm motility in sows, etc. has gradually become a hot topic of research
