Additive of feedstuff for promoting oestrus of sow

Abstract

A feed additive for promoting the empathena of sow and improving the sexual function and reproduction power of sow is proportionally prepared from 13 raw materials including VE, VA, sodium selenite, biotin, Chinese angelica root, epimedium, motherwort, the chelate (3D) of amino acid and trace elements, etc.

Description

[0001] Technical field: the present invention relates to a feed additive for sows, in particular to a feed additive for promoting estrus in sows. Background technique: [0002] In the process of professional pig raising, one of the production problems that is often encountered is that the time between sows is prolonged, the litter size is small, and there is no estrus for a long time. It often leads to low reproductive utilization of sows and high feed consumption, which is the main reason for sow culling. [0003] In order to solve this technical problem in sow production, after years of scientific and technological research and clinical practice, the key factors affecting the reproductive performance of sows have been found out: [0004] First: As a special production machine, the nutritional level of the sow is extremely important. If the feed that provides the source of nutrition for the sow cannot meet the needs of the sow’s reproduction, it will cause the sow’s metabolis...

Problems solved by technology

[0004] First: As a special production machine, the nutritional level of the sow is extremely important. If the feed that provides the source of nutrition for the sow cannot meet the needs of the sow’s reproduction, it will cause the sow’s metabolism to lose coordination, endocrine dysfunction, and inhibit the sow’s estrus and ovulation;

[0005] Second: the influence of disease factors. During the breeding process of sows, they have to go through the process of estrus-mating-pregnancy-delivery-lactation, etc. During these processes, pathogenic bacteria are brought into the reproductive tract due to lax disinfection measures, or because of Sows are prone to endometritis, ovarian cysts and infectious diseases that affect reproduction due to the decline of sow resistance and infection of pathogenic bacteria
