Abstract

The invention discloses an application of magnolol in improving reproductive performance of sows. By adding magnolol to feed for breeding the sows in the gestation period and the lactation period, the effects of improving the reproductive performance of the sows are found through research for the first time, specifically including reducing the loss of the backfat thickness of the sows in the lactation period, increasing backfat thickness of the sows during weaning of piglets, shortening oestrus interval of breeding sows, enhancing the antioxidant capacity of serum of weaned piglets produced by the sows, increasing the length of small intestines of the weaned piglets, effectively improving the digestion and absorption functions of the small intestines of the weaned piglets, and alleviating diarrhea of the weaned piglets. Therefore, magnolol not only can significantly improve the health state of the breeding sows and improve the reproductive performance, but also can indirectly influence the breeding performance of weaned piglets through the sows so as to achieve the purpose of improving the reproductive performance of the sows. Therefore, magnolol can be used as a feed additive or a health-care medicine for improving the reproductive performance of sows.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to the application of magnolol in improving the reproductive performance of sows. Background technique [0002] The sow is the core of the modern pig industry. The number of piglets that a breeding sow can provide and the performance of its offspring determine the overall efficiency of the pig industry. However, the health status of breeding sows can affect embryonic development through the placenta during pregnancy, leading to weak piglets and birth defects; it can also directly affect the early growth of piglets through breast milk. At the same time, the changes of breeding sows in the gestation and lactation stages will have a long-term impact on offspring pigs. Therefore, in addition to litter performance, the reproductive performance of sows also includes farrowing rate, interval from weaning to re-estrus, pre-weaning mortality, etc. , and the growth perform...
