Description
Technical field
The invention belongs to the formula for pig forage technical field, be specifically related to broad sow concentrated feed perinatal period.
Background technology
China is that the first in the world is cultured big country, and the sow livestock on hand accounts for 60% of world's total amount, but pork output only accounts for 48.8% of global total amount.This mainly is that according to statistics, China sow year number pigs weaned is the 15-18 head because sow production performance is low, can reach more than 25 and culture developed country.The key that influences sow production performance is perinatal period, referred to for antenatal 1 thoughtful 1 week of postpartum perinatal period, this class relationship produces the breeding rate of oestrusing, the breeding conception rate of the young number of work, newborn piglet vigor, weaned piglet weight, sow to the sow nest, or even the service life of sow.
Perinatal period is key because of the reproductive performance that is related to sow, also paid close attention to because a breed difficult problem, perinatal period multiple problem be low, the agalasisa of constipation, difficult labour, postpartum inflammation, feed intake, the breeding and the piglet regularity is poor, yellowish-white dysentery etc. of can not in time oestrusing, be commonly referred to as syndrome perinatal period.Perinatal period, general solution was at present: 1) improve nutrition with the lactation material, improve birth weight and piglet regularity; 2) use the antibiotic prophylaxis inflammation in a large number; 3) prevent that stages of labor is long, use the oxytocin practise midwifery in a large number, use oxytocin to accelerate lochia simultaneously and discharge.
In order to improve the piglet birth weight, satisfy low feed intake demand in postpartum, the raiser is many to feed perinatal sow with the lactation material, because there is not special sow feed perinatal period on the market.In fact the trophic level of lactation material can not satisfy sow nutritional need perinatal period, and on the one hand period of pregnancy, the anabolism ability was strong, and the lactation material of high energy, high egg causes easily that the piglet birth weight is excessive has difficult labour; The high egg of high energy easily causes overnutrition, not only makes sow fertile partially, and the fat deposition bag is by breast, ovary, also can aggravate the metabolism pressure of organs such as the heart, lung, liver, kidney and gives a birth unable.On the other hand, antenatal postpartum, the sow feed intake was low, especially postpartum, the average feed intake 2-3kg of sow, even do not eat in continuous several days, reproduction nutrient in the lactation material, the relevant nutrient of immunity, limb hoof nutrient, health medicine isoconcentration are to arrange about 6-8kg at feed intake, so concentration is nowhere near, influence the sow recovery and give milk; And the high energy of lactation material, high egg are unfavorable for that sow appetite in postpartum recovers.In addition, antenatal postpartum sow because physiological reason, easily constipation, fiber content is low in the lactation material, easily aggravates constipation.
After using the lactation material, sow is easily had difficult labour, postpartum inflammation, antibiotic prevents, anti-inflammatory so can rely on, and relies on oxytocin and carries out uterine contractile.Lactation material and a large amount of adding of 1 week in antenatal postpartum broad-spectrum antibiotics not only can kill the profitable strain in the genital tract in a large number, also can cause constipation, drug resistance, lesions of liver and kidney etc.In fact sow is easily had difficult labour, the reason of inflammation is that the piglet size is inhomogeneous, and the sow stages of labor is long, force of labor is not enough, and lochia etc. can not in time be discharged, and sow nutrition insufficiency of intake, resistance are poor.Adding antibiotic can only auxiliary curing infect, and can not fundamentally reduce infection.Though oxytocin can strengthen uterine contractile, is not suitable for multiparous animal, for the narrow and small sow of abnormal fetal position, pelvic cavity disaster especially, and rely on the balance that oxytocin can be upset organism endocrine, be unfavorable for that sow recovers.
At present the perinatal nutritional need of sow does not appear in the newspapers as yet, and perinatal care product mostly are functional additive, can't system, comprehensively provide nutrition and a solution production difficult problem.Patent documentation CN102652537A has announced broad sow feed perinatal period, be characterized in improving the nutrient concentration of albumen, energy, amino acid etc., add three kinds of functional raw materials (rupture of membranes globulin powder, brewer's yeast, goldbeater's skin albumen) simultaneously, purpose be improve sow appetite perinatal period, reduce stress, thinking is with generally the lactation material is identical.The present invention then is fit to physiology and the trophic level of producing needs perinatal period by determining out, simultaneously by shortening stages of labor, promoting lochia to discharge, improve the recovery that immunity of organisms reduces inflammation, promotion birth canal in postpartum.Antenatally improve the piglet uniformity and the piglet vigor does not rely on the lactation material, power is provided in the product, shortens stages of labor and do not rely on oxytocin, promote postpartum lochia to discharge, reduce inflammation and do not rely on antibiotic.
