Pig feed capable of improving sow lactation

Abstract

The invention belongs to the technical field of animal feed, and particularly discloses pig feed capable of improving sow lactation. The pig feed comprises zinc bacitracin, selenium yeast, vitamin E, xylooligosaccharide, vitamin C, vitamin B12, folic acid, complex vitamin, copper sulfate solution of 25% in concentration, ferrous sulfate solution of 30% in concentration, ferrous fumarate solution of 30% in concentration, zinc sulfate solution of 34.5% in concentration, manganese sulfate solution of 31.8% in concentration, calcium iodate, methionine, corn, wheat bran, bean pulp, corn gluten meal, valine of 99% in concentration, zeolite powder, vaccaria segetalis seed, calcium carbonate powder, calcium hydrogen phosphate, sodium chloride, lysine solution of 70% in concentration, anhydrous sodium sulfate, choline solution of 50% in concentration and soybean oil. By the pig feed, the problem of poor piglet growth condition caused by the fact that existing pig feed is low in sow lactation yield in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of animal feed. Background technique [0002] Sows, as producers in the pig raising chain, play a key role in ensuring the economic benefits of pig farms. Especially lactating sows shoulder the heavy responsibility of nurturing piglets and continuing reproduction. Breast milk is the main source of nutrition for piglets within 20 days after birth, and the lactating ability of sows determines the growth rate and growth rate of piglets. However, one of the factors currently restricting the development of the pig industry is that sows have insufficient lactation during the lactation period, resulting in less milk intake, malnutrition, and easy illness or death during the weaning period, resulting in a small number of pigs in stock and slow production speed. To improve the lactation of breeding pigs, it is necessary to provide sufficient nutrition for lactating sows. Therefore, the basic task of feeding and man...

Problems solved by technology

[0003] Existing lactation feeds generally add prolactin, although it has a certain effect on improving the milk production of sows, but the hormone is difficult to digest in the animal body, and it is also difficult to excrete from the animal body through excretion, making the hormone often residues in animals

The hormones remaining in the sows are extremely harmful: 1) first of all, they will cause harm to the sows. If the sows eat hormone-containing feed for a long time, it will disrupt the secretion of the mammary system of the sows and destroy the sows. The function of the mammary glands may seriously cause the sows not to lactate

2) The hormones that cannot be excreted remain in the body of the sow. For consumers, eating pork containing hormones will also affect human health

3) Residual hormones will also enter the piglets with the milk, seriously affecting the balance of hormones in the piglets and affecting the development of piglets
