Premix feed for increasing weaning estrus rate and mating and farrowing rate of empty sow and preparation method of premix feed

Abstract

The invention relates to the technical field of sow feed premixes, in particular to a premix feed for increasing the weaning estrus rate and the mating and farrowing rate of an empty sow and a preparation method of the premix feed. As for the premix feed, through reasonable compatibility of Chinese herbal medicines, and reasonably addition of trace nutritional factors, the Chinese herbal medicine components are mutually combined with the trace nutritional factors to generate action, so that the quality of ovum of the empty sow is effectively improved, the postweaning estrus days of the empty sow are lowered, and the mating and farrowing rate of the empty sow is increased.

Description

technical field [0001] The invention relates to the technical field of feed premix for sows, in particular to a premix feed for improving the weaning estrus rate and mating delivery rate of empty sows and a preparation method thereof. Background technique [0002] The sow is the core link of pig breeding. The reproductive ability of the sow directly affects the economic benefits of the pig farm; however, the reproductive ability of the sow is affected by many factors. For those who are not pregnant or just Empty sows after production have experienced a high-intensity stage of lactation, and there is a large body loss, and body loss will lead to changes in the secretion of hormones in the sow, which in turn will affect the development of the sow's ovaries and the production of eggs. Mature. Especially in the high temperature environment in summer, it leads to a decline in the feed intake of sows during the lactation period, resulting in a serious loss of fat in sows, resulti...

Problems solved by technology

[0003] In view of this, in county-level technology, a lot of research has been done on empty sow premix or sow feed. For example, the patent application number is 201710124701.X, which uses barley, Brown rice, sorghum, soybean meal, silage feed, sudan grass hay, white clover hay, bran, calcium hydrogen phosphate, salt, fish meal, silkworm chrysalis powder, vitamins, and Chinese herbal medicine additives. The vitamins used are vitamin A, vitamin D, and vitamin E , niacin, pantothenic acid, vitamin B12, etc., the traditional Chinese medicine additives are Acanthopanax, motherwort, safflower, cinnamon, astragalus, Ligustrum lucidum, tangerine peel, shell, dandelion, dodder, flavescens, Eucommia; The formula is adjusted so that the ratio is reasonable and the nutrition is balanced, which helps sows to recover their physical fitness after delivery, and improves the reproductive performance and fertilization rate of empty pregnant sows; it can be seen that in the prior art, it mainly tends to improve the physical fitness of empty pregnant sows. Restoration allows the sows to consume a large amount of energy substances and improve the physical fitness of the sows; however, it does not solve the problem of long estrus time after weaning of empty sows. , protein, minerals, vitamins, etc., and also related to special physiological cycles such as ovulation and egg maturation of empty pregnant sows
