Functional complemental feed for Danish high-yield sows at perinatal period and feeding method of functional complemental feed

Abstract

The invention discloses a functional complemental feed for Danish high-yield sows at the perinatal period. The functional complemental feed comprises beet pulp, oat bran, puffed linseed meal, chocolate powder, calcium chloride, calcium hydrogen phosphate, table salt, N-carbamylglutamic acid, a composite premix feed for lactation sows, amino acids, a radix astragali extract, a radix codonopsis extract, radix angelica sinensis and dried orange peel. According to the functional complemental feed disclosed by the invention, through organic combination of dietary fibers, quick energy supply and Chinese herbal medicines, through cooperation of the usage of a feed for the lactation sows, and through blood sugar concentration adjustment, the functional complemental feed can nourish qi and blood, enhance immunity, clear heat, remove toxicity, prevent miscarriage, adjust intestinal tracts, promote postnatal womb contraction and restoration, shorten lochia discharging time, control postnatal infection, increase the birth weight of piglets, increase the vitality of the piglets, reduce the number of dead fetuses and increase the food consumption of the sows at the lactation period.

Description

technical field [0001] The invention relates to the technical field of feed for pigs, and more specifically relates to a peripartum functional supplementary feed and a feeding method thereof for high-yield Danish sows. Background technique [0002] The peripartum period refers to a transitional period from pregnancy to lactation. Although the period from late pregnancy to early lactation is short, it is very important for the production performance of high-yielding sows, because this stage is in the early stage of colostrum synthesis, and the nutrient supply in the body is in the stage of redistribution from embryo to mammary gland tissue. Due to the dual stress of physiology and environment, and the birthing process is an extremely energy-consuming physiological process, the special needs of nutrition for a large litter size, such as nutrition cannot be met or the supply is insufficient, the problems that arise are particularly prominent, such as Stress oxidation, prolonge...

AI Technical Summary

Problems solved by technology

[0004] Compared with the Canadian, American, British, and French breeds, the Danish breed has excellent reproductive performance, with a high number of litters but a low birth weight, which directly brings about a series of problems: piglets’ demand for milk increased, sows need more nutrients to meet lactation needs; while modern sows generally have poor appetite and insufficient feed intake during lactation, therefore, Danish high-yielding sows have higher nutritional requirements for feed

One is to use feed for pregnant sows, because the low nutrient concentration will lead to intrauterine growth retardation, which will lead to high birth rate of weak piglets and decreased vitality; t
