Assorted feed for lactating sows

Abstract

The invention discloses an assorted feed for lactating sows. The assorted feed for the lactating sows is prepared from the following raw materials in parts by weight: 10-20 parts of stem pith of the rice-paper plant, 20-30 parts of black soybeans, 50-60 parts of bone powder, 40-80 parts of kudzu-vine root powder, 30-50 parts of soybeans, 30-40 parts of animal oil, 50-90 parts of green fodder, 200-230 parts of corn powder, 1-1.2 parts of nutritional supplements, 2-2.6 parts of vitamin supplements and 2-2.5 parts of trace-mineral supplements. The assorted feed can be rapidly adapted by the sows. The assorted feed is capable of increasing food intake, improving immunity, raising piglet survival rate, avoiding weight-loss of the weaning sows, shortening weaning estrus periods of the sows, increasing milk yields of the sows, and improving milk qualities of the milk produced by the sows; thus, the assorted feed has wide market prospects.

Description

technical field [0001] The invention relates to the field of feed, in particular to a compound feed for lactating sows. Background technique [0002] Pig occupies an important position in my country's national economy and is a major pillar industry of my country's rural economy and animal husbandry. In recent years, the pig raising industry has developed rapidly, and the way of raising pigs is rapidly changing from the family-style free-range pig raising of thousands of households to large-scale and professional pig raising. The evolution from half open to closed, the feeding management method has changed from extensive to refined, and the heredity of breeds and production performance have improved rapidly. At the same time, pigs have become more demanding and strict on nutrition, feed, and environment. Therefore, the research on pig nutrition is very active, constantly updating and expanding from concept to content. [0003] With the continuous increase of pork prices in ...

Problems solved by technology

[0003] With the continuous increase of pork prices in recent years, the pig industry has gradually become larger and larger. In order to increase production value, it is necessary to provide pigs with different feeds for different purposes, and sows also need to be targeted in postpartum breastfeeders. A kind of feed, during the postpartum lactation period of sows, often due to various problems, the milk production of sows is insufficient, and the sows lose weight after feeding piglets, resulting in weight loss of sows. During this period, the immunity is reduced due to insufficient nutrition, which affects the survival rate of piglets, resulting in a decline in the survival rate of piglets
