Problems solved by technology

Under normal circumstances, the abortion rate of sows during pregnancy is 20%-45%, and most of the abortions occur in the first 25 days of pregnancy. In addition, abortions are also prone to occur at 60-70 days of pregnancy. It directly leads to the reduction of litter size. If the abortion occurs after the sow is mated, it may also cause the sow to prolong the reproductive cycle. It may even cause some sows to completely lose their fertility and then be eliminated, causing great economic losses to pig farmers.

Abstract

The present invention relates to the field of compound premixed feeds and more particularly relates to a miscarriage preventing premixed feed for pregnant sows. The premixed feed comprises a nutritional additive, Chinese herbal medicinal additives and a diluent. The content of crude medicinal materials in the Chinese herbal medicinal additives is 0.5-8% by weight of the premixed feed and the Chinese herbal medicinal additives are prepared by an extraction preparation or a direct crushing of the medicinal materials in the following parts by weight: 0.5-3 parts of radix angelicae sinensis, 0.5-3 parts of rhizoma chuanxiong, 0.5-3 parts of rhizoma atractylodis macrocephalae, and 0.5-3 parts of cortex eucommiae. The diluent is a mixture of zeolite powder to rice hull powder at a weight ratio of 1:1. The product can meet the needed vitamins, trace elements, amino acids, etc. in the growth and development stages of the pregnant sows, improves production efficiency and enhances immunity. The added Chinese herbal medicinal additives have effects of preventing miscarriage and strengthening piglets, strengthening spleen and supplementing kidneys, and supplementing blood and securing exterior, can prevent miscarriage, prevents dead embryos, increases the litter sizes of the pregnant sows and the weight of the newborn piglets, increases the appetite and disease resistance of the sows, etc.

Description

technical field [0001] The invention belongs to the application field of agriculture and animal husbandry, and in particular relates to a premixed feed for pregnant sows for anti-tocolysis and a preparation method thereof. Background technique [0002] Abortion refers to the phenomenon that a sow is pregnant for less than 16 weeks, and the pregnancy is terminated before the fetus is born and has the ability to survive. Under normal circumstances, the abortion rate of sows during pregnancy is 20%-45%, and most of the abortions occur in the first 25 days of pregnancy. In addition, abortions are also prone to occur at 60-70 days of pregnancy. It directly leads to a reduction in litter size. If abortion occurs after the sows are mated, the reproductive cycle of the sows may be prolonged. Some sows may even completely lose their fertility and be eliminated, causing great economic losses to pig farmers. There are many reasons for sow abortion, such as reproductive tract disease, ...
