Feed additive for health protection of breeding sow trotters and application method of feed additive

Abstract

The invention discloses a feed additive for the health protection of breeding sow trotters and an application method of the feed additive. The feed additive contains zinc glycinate, manganese glycinate, copper glycinate, vitamin E, vitamin A, vitamin D3, selenium yeast, a sweetening agent and wheat middling. According to nutrition factors influencing the health of the breeding sow trotters and unique physiological characteristics of breeding sows, various organic microelements, vitamins and functional substances are applied to the breeding sows; the balance among the organic microelements is also considered; experiments show that the probability of cyllopodia can be lowered effectively, the mortality of the breeding sows is reduced and the born number of the breeding sows and the weaning weight of piglets are increased. The additive is convenient to prepare and use and is low in cost; the organic microelement is a single amino acid chelating ligand such as glycine and the feed additive has the common applicability.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for sow's hooves health care and its application method. Background technique [0002] At present, my country's pig industry is transforming into a large-scale, intensive, and specialized production mode. Sow feeding management is a key link in pig production, and the health of sow hooves is the main factor affecting lifetime productivity. Unhealthy sow hooves not only directly lead to lameness of sows, prolonged lying time, reduced feed intake, reduced litter size and reduced weaning weight; Sow update knocks out turnover rate. [0003] The main goal of modern genetic breeding for sow breeding is to pursue high litter size, high lean meat percentage, and high growth rate, so higher requirements are put forward for the health of sow's hooves. However, due to the way of captivity, inappropriate floor boards and poor quality, inadequate feeding and management during the breeding...

AI Technical Summary

Problems solved by technology

However, due to the way of captivity, inappropriate floor boards and poor quality, inadequate feeding and management during the breeding season, unreasonable backfat thickness and nutritional reasons, coupled with the fact that producers do not pay attention to the health of sows' hooves, the current sows are lame. high incidence of foot

Most lameness causes pain in the hooves of sows, but it is currently not possible to measure the pain level, thus underestimating the damage caused by lameness
