Feed additive for sows and preparation method thereof

Abstract

The invention provides a feed additive for sows, which belongs to the technical field of feeds; the feed additive comprises the following raw materials: the root of membranous milk vetch, poria cocos, motherwort, akebia stem, semen cuscutae, dandelion, kudzuvine root, coix seed, the rhizome of chuanxiong, liquorice root, dried tangerine or orange peel, verbena, lotus leaf, elecampane, honeysuckle, the rhizome of Chinese atractylode, isatis root, medicated leaven, paulownia leaf, pulsatilla chinensis, purslane herb, spina date seed, Tokyo violet herb and paris root. According to the sow feed additive, the endocrine system of sows is regulated by utilizing the warming and nourishing effects of Chinese herbal medicines, so that the secretion of prolactin is increased, the milk yield is further increased, the sow feed additive is high in lactation promoting speed, the milk yield of the sows is increased by 20-30% after the sows are fed for two days, side effects are avoided, and the feeding amount is relatively small. A good effect can be achieved by feeding 0.2-0.5 g of the sow with the weight of 180 kg every day, the milk yield of the sow is increased, the breast milk quality is improved, the feed intake of piglets delivered by the sow can be met, the growth of the piglets is promoted, and the purpose of increasing economic benefits is achieved.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a feed additive for sows and a preparation method thereof. Background technique [0002] With the rapid development of China's modern agriculture in recent years, the pig industry, as one of the important industries of China's national economy, has also developed rapidly. Sow is one of the basic conditions for the development of breeding industry and the expansion of breeding scale. The lactation period is an extraordinary period for sows to reproduce. The lactation sows must not only ensure sufficient intake of nutrients to maintain their own life needs, but also secrete milk to supply the piglets, and at the same time restore their bodies. At this time, the sows’ immunity If it is low, it will easily lead to a decline in milk production and production performance. Once the milk secretion is insufficient or the milk quality is not good, it will inevitably affect the growth and dev...

However, purely from the perspective of "supplementation", it may not be able to achieve or continue to achieve the desired effect, which is not conducive to the regulation of the overall function of the sow, and even causes the accumulation and waste of nutrients, and at the same time cannot improve the quality of breast milk
