Description
Technical Field
The invention belongs to the field of feed additives, and particularly relates to a functional nutritional additive for improving birth weight of piglets and preventing constipation of sows.
Background
The sow can be divided into a back-up stage, a pregnancy stage, a lactation stage and a nonpregnant stage according to the production process, and at present, 1 week before and after parturition is divided into a perinatal stage. Pregnant sows are sows that have been bred successfully to the stage of delivery, and the gestation period is generally 114 days, and can also be 3 months and 3 weeks plus 3 days in a3 month period. The general gestational period is divided into three stages: the fetal nidation period, the body condition adjustment period and the fetal rapid development period are different, but the specific division time of the three periods is different, mainly the time nodes between the body condition adjustment period and the fetal rapid development period are different from 75-95 days. Since sows do not produce any benefit at the surface of the gestation period, they are not paid sufficient attention from both nutrition and management.
At present, the technical scheme for improving constipation of pregnant sows and promoting rapid development of fetuses mainly comprises compound feed, premixed feed, single additive and the like.
Chinese patent 'a premixed feed for pregnant sows', application number: CN201710116642, publication no: CN106889331A, the invention provides a premix feed for pregnant sows, which has good effects on solving the problems of sow abortion constipation, weak litter, and the like caused by hemopoiesis, qi tonifying and insufficient dietary fibers. However, because the invention uses a large amount of fish meal and fermented soybean meal as raw materials at this stage, the feeding cost is greatly increased, and the popularization and application are not facilitated. The mulberry leaves can effectively provide dietary fibers, but the mulberry leaves are regionally planted and still cannot be popularized in a large area as feed raw materials, so that the method is not beneficial to popularization in non-mulberry-leaf planting areas.
Chinese patent 'a pregnant sow feed', patent application number: CN201710070209.9, publication No.: CN106721322A the feed prepared by the invention can ensure the basic nutrition level of the pregnant sows, and simultaneously, microelements, vitamins, amino acids and organic acids are added to ensure the balanced nutrition of the pregnant sows, thereby increasing the breeding potential of the pregnant sows, improving the embryo survival rate, ensuring the good development of the fetus, and maintaining the normal physique and weight gain of the sows during the pregnancy. However, the invention does not refer to the feeding stage, but only provides a basic feeding amount, which is not beneficial to the fine nutrition regulation in stages, and the feeding amount is far lower than the required amount in the later stage of pregnancy, especially after 95 days, so that the fetus is difficult to grow and develop quickly.
