Mixed feed added with microbial additive special for sows

Abstract

The invention discloses a mixed feed added with a microbial additive special for sows. The mixed feed is prepared by uniformly mixing 99.8 to 99.9 percent of batch with 0.1 to 0.2 percent of microbialadditive, wherein the microbial additive is prepared from 2 to 3 parts of saccharomyces cerevisiae, 1.5 to 1.85 parts of bacillus subtilis and 0.01 to 0.05 part of lactobacillus acidophilus. According to the mixed feed added with the microbial additive special for sows, microorganisms are reproduced and enriched inside sows to produce cellulase, xylanase, beta-dextranase, amylase, protease, lipase, organic acids and other substances, so that the absorption of calcium, phosphorus, iron and other elements as well as organic trace elements is enhanced, the ovulation numbers of the sows are increased, the piglet delivery numbers of the sows are increased, a stomach and intestine nourishing effect is achieved, the growth of probiotics such as lactobacillus acidophilus and escherichia coli is promoted, the micro-ecological balance of the whole gastrointestinal tract is maintained, the production of toxins inside the animals is reduced, and the stress resistance and immunity of the sows areenhanced; the mixed feed plays a remarkable role in reduce the feces odor of the sows.

Description

Technical field: [0001] The invention relates to a special mixed feed for sows added with microbial additives, belonging to the technical field of animal feed. Background technique: [0002] In pigs, female pigs of any age who have given birth to piglets are called sows. There are many types of sows, which are classified according to color, including black sows, white sows, and piebald sows. Their living habits are also different. There are certain differences. According to the region, some sows mainly eat half-cooked food, some mainly eat cooked food, and some eat raw food. The feeding of sows is different from that of ordinary meat-producing pigs. They are high-quality and comprehensive in nutrition. The feed is very important to the body shape development and reproductive system development of sows; under normal circumstances, sows give birth to 2 litters per year, and each litter produces 8 to 10 piglets. The growth and development of pigs in the normal period is obviou...

[0002] In pigs, female pigs of any age who have given birth to piglets are called sows. There are many types of sows, which are classified according to color, including black sows, white sows, and piebald sows. Their living habits are also different. There are certain differences. According to the region, some sows mainly eat half-cooked food, some mainly eat cooked food, and some eat raw food. The feeding of sows is different from that of ordinary meat-producing pigs. They are high-quality and comprehensive in nutrition. The feed is very important to the body shape development and reproductive system development of sows; under normal circumstances, sows give birth to 2 litters per year, and each litter produces 8 to 10 piglets. The growth and development of pigs in the normal period, but it is obviously not enough for the nutrient reserves of sows during pregnancy and lactation, let alone enhance the sow's physique to prolong the life of litters, nor can it increase the litter size per litter

[0003] The nutritional needs of sows are important factors to ensure reasonable body condition, high reproductive capacity, long service life, and high health level. Therefore, to strengthen feeding management, the nutrition obtained from feed plays a vital role in sows, and Nutritional needs of sows vary greatly at different reproductive stages, so it is very important to use appropriate feed and feed appropriate amounts at different stages for healthy and efficient breeding of sows; research and practice have shown that high nutrient intake in the early pregnancy It is not conducive to the survival of embryos and the feed intake of sows during lactation, so the sows should be restricted in the early pregnancy; and the nutritional restriction in the middle of pregnancy will affect the body condition of sows, fetal growth and muscle fiber accumulation, mammary gland development and birth weight. There is a big change; increasing the feeding level in the late pregnancy has a certain effect on promoting the birth weight and survival rate of piglets, but excessive feed intake will cause a decrease in feed intake during lactation, increased weight loss, and reduced lactation, which will lead to increased production capacity. decline; the nutritional level of lactating sows not only directly affects the lactation ability of sows and the growth and development of piglets, but also affects the reproductive performance of sows in the next litter. The nutritional needs of pigs for feed are imminent
