Problems solved by technology

Due to the low heritability of litter size in sows (heritability is between 0.03 and 0.24), genetic breeding experts try to increase the litter size of pigs through genetic selection, but the genetic progress achieved is limited and takes a long time ,higher cost

Abstract

The invention discloses a compound feed capable of increasing the effective litter size of sows. The compound feed is prepared from the following raw materials in parts by weight: corn, soybean meal, bran, wheat middling, soybean oil, fat powder, soybean fibers, edible salt, choline, limestone powder, calcium hydrogen phosphate, an acidifier, a mildew preventive, lysine, glutamine, rice hull powder, phytase, an enzymic preparation, a mold removal agent, an antioxidant, organic chromium, saccharomycetes, a living bacteria agent, VE, biotin, folic acid, ferrous methionine chelate, vitamin A, beta-carotene, VB2, selenium yeast, zinc yeast, N-carbamylglutamic acid, various trace mineral elements and various trace vitamins. After the compound feed is eaten by pregnant sows, the numbers of mummies, dead fetuses and scrawny piglets in the litter size are effectively reduced, and the effective live litter can be increased by 1 per litter.

Description

technical field [0001] The invention relates to a compound feed for sows, in particular to a compound feed for increasing the effective litter size of sows. Background technique [0002] The reproductive performance of sows is one of the important goals pursued by pig farmers, and the reproductive performance of sows directly determines the economic benefits of raising pigs. The reproductive performance of sows raised in the current intensive pig farms in my country is poor, which limits the further development of my country's pig industry. The litter size of sows includes several aspects of data or concepts according to different targets, such as the total number of litters including mummies and stillbirths; the number of fully formed piglets includes stillbirths, but not mummies; All live piglets after mummies and stillbirths; while effective litter size is the number of piglets after culling weak piglets. The litter size during childbirth is affected by factors such as ...
