Concentrated feed for lactating sows and processing method of concentrated feed for lactating sows

Abstract

The invention discloses a concentrated feed for lactating sows, and belongs to the field of pig feeds. A premix comprises lactose, glucose, calcium powder, methionine, choline chloride, threonine, an acidifying agent, a flavoring agent, vitamins for porkets, microelements for the porkets, sodium bicarbonate, eggs, chestnut kernel meal, peanut kernel meal, 98.5% lysine, sweet potato stems, sweet potato leaf meal, dried potato meal, pig sprouts, plantain herb, millet, sorghum, ethoxy quinoline, green vegetables, corn flour, pumpkin, soybean curb residue and soya-bean milk. The invention also provides a preparation method of the concentrated feed for the lactating sows. The method comprises the following steps: (1) preparing the premix; and (2) preparing the feed. The concentrated feed is used for feeding the sows during late pregnancy, and is capable of promoting rapid porcine fetal growth, increasing the birth weight of piglets, ensuring the relatively large-capacity ingestion, relatively large-capacity milk production and relatively little fat loss, promoting the weaning, empathema and hybridization as quickly as possible, and effectively improving the farming income.

Description

technical field [0001] The invention relates to a concentrated feed for lactating sows and a processing method thereof, belonging to the field of pig feed. Background technique [0002] The benefit of raising pigs depends largely on the reproductive efficiency of sows. Sow nutrition deficiency will have the following consequences: small litter size, poor uniformity, low survival rate, small birth weight of piglets, light weight of weaned litter; prolongation of estrus time after weaning or no estrus, and shortened effective use period; Paralysis before and after childbirth, physical weakness, decline in comprehensive production performance, etc. For lactating sows, their nutritional status is directly related to the growth and development of suckling pigs. If a lactating sow is malnourished, it will lead to a decrease in feed intake, less milk production, more fat loss, and a delay in estrus and mating time. It can also cause slow growth, low immunity, small feed intake, a...

Problems solved by technology

Sow nutrition deficiency will have the following consequences: small litter size, poor uniformity, low survival rate, small birth weight of piglets, light weight of weaned litter; prolongation of estrus time after weaning or no estrus, and shortened effective use period; Paralysis before and after childbirth, physical weakness, decline in comprehensive production performance, etc.

For lactating sows, their nutritional status is directly related to the growth and development of suckling pigs. If a lactating sow is malnourished, it will lead to a decrease in feed intake, less milk production, more fat loss, and a delay in estrus and mating time. It will also cause slow growth, low immunity, low feed intake, and low daily weight gain of suckling piglets, which seriously restricts farmers' enthusiasm for breeding
