Concentrated feed for sows in perinatal stage

Abstract

The invention discloses a concentrated feed for sows in a perinatal stage. The feed mainly contains wheat germ proteins, bean hulls, brown sugar, wheat starch, calcium formate, anhydrous sodium sulphate, glucose oxidase, arginine and Chinese medicine extracts. When being used before delivery, the feed can achieve the remarkable efficacies of shortening the delivery stages of the sows and promoting the discharge of lochia so as to accelerate the recovery of birth canals; the suckling piglets can healthily grow fast, the postweaning estrus intervals of the sows are short, the mating conception rate is enhanced greatly and the mortality is low. The feed has the advantages of reducing perinatal stage syndromes, enhancing the delivery results of the sows, and releasing the current cultivation from the dependence on medicines, thereby greatly reducing the use of the medicines in cultivation.

Description

technical field [0001] The invention belongs to the technical field of pig feed formula, and in particular relates to a perinatal concentrated feed for sows. Background technique [0002] my country is the world's largest breeding country, with sows accounting for 60% of the world's total, but pork production only accounts for 48.8% of the global total. This is mainly due to the low production performance of sows. According to statistics, the number of weaned piglets per year in my country is 15-18, while that in developed countries can reach more than 25. The key to affect the performance of sows is the perinatal period. The perinatal period refers to 1 week before delivery to 1 week after delivery. This stage is related to the number of live piglets in the sow litter, the vitality of newborn piglets, the weaning weight of piglets, and the estrus and mating of sows. rate, service conception rate, and even lifespan of the sow. [0003] The perinatal period is critical beca...

Problems solved by technology

In fact, the reason why sows are prone to dystocia and inflammation is that the piglets are uneven in size, the sows have a long labor process, insufficient productivity, postpartum lochia cannot be discharged in time, and sows have insufficient nutritional intake and poor resistance

Adding antibiotics can only assist in the treatment of infection, but cannot fundamentally reduce infection

Although oxytocin can enhance uterine contraction, it is not suitable for multiparous animals. It is even more disastrous for sows with abnormal fetal position and small pelvic cavity. Moreover, oxytocin will disrupt the balance of endocrine in the body, which is not conducive to the recovery of sows.

[0006] At present, the nutritional needs of sows during the perinatal period have not been reported. Most of the perinatal health care products are functional additives, which cannot provide nutrition systematically and comprehensively and solve production problems.
