Functional clean daily food special for sows at pregnancy later period

Abstract

The invention relates to a functional clean daily food special for sows at the pregnancy later period. The functional clean daily food comprises corn, barley, soya bean meal, soya-bean oil, imported fish meal, rock powder, calcium hydrophosphate, sodium chloride, montmorillonite, flour, cassava dregs, bran, alfalfa meal, wood fibers excepted for cassava dregs, fructose, vitamin premix, microelement premix and traditional Chinese medicine premix in certain content. According to the functional clean daily food, according to the variation of the physiological requirements of the sows at the pregnancy later period, the contents of all the components are reasonably matched, daily food nutrient regulation is carried out, preparation of labor onset is earlier started, the labor stage is effectively shortened, and the proportion of weak piglets and dead fetuses is decreased; the birth weight and the uniformity degree of the piglets and the colostrum component content are increased. According to the functional clean daily food, the traditional Chinese medicine ingredients are led in, the livers of the sows at the pregnancy later period are protected, the initiative detoxification and metabolic capability of the livers for mycotoxin are improved, and the immunologic function of whole systems of the sows at the pregnancy later period is fundamentally improved.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and relates to a special functional clean diet for sows, in particular to a special functional clean diet for sows in late pregnancy. Background technique [0002] The peripartum period refers to the special period of 3 days before and after the delivery of pregnant sows. Since the feeding of pigs uses "weeks" as the unit, the perinatal period is set as 1 week before delivery to 1 week after delivery. Sow peripartum syndrome mainly includes prolonged labor, dystocia, increased stillbirth, sow postpartum fatigue, food loss or no food, postpartum angalactia, and even MMA (metritis, mastitis, and agalactia syndrome). [0003] Sow farrowing is a great stress for both the mother and the newborn fetus. In a relatively short period of time, sows experienced drastic changes in hormone levels (a sharp drop in plasma progesterone levels, accompanied by increases in insulin and prolactin levels) and ph...

AI Technical Summary

Problems solved by technology

On the one hand, excess dietary energy causes the body condition of sows to be too fat, and excessive fat deposition around the uterus, subcutaneous, and peritoneum causes fatigue during childbirth, prolongs the calving time, and increases the proportion of stillbirths; Excess energy, resulting in an oversized fetus

Piglets that are too large during delivery can easily damage the birth canal, causing birth canal edema, hemorrhage, etc., and postpartum infection; according to research reports, birth weight of fetuses exceeding 1.8kg will significantly increase the birth canal resistance of sows during delivery, causing prolonged labor

In addition, most pig farms in my country implement a feed change program in the late pregnancy, that is, when the low-protein diet in the early pregnancy is transferred to the high-protein lactation feed in the late pregnancy, the ability of the large intestine to absorb and secrete fluids is relatively changed. , resulting in the inability to absorb excess nitrogen, and the excretion of urinary nitrogen will take away a large amount of water, which can easily lead to constipation
