Feed formula for improving production performance of sows and preparation method thereof

Abstract

The invention relates to a feed formula for improving production performance of sows and a preparation method thereof. The feed formula consists of the following raw materials in parts by weight: 632-695 parts of corns, 180-250 parts of bean pulp, 0-70 parts of extruded soybeans or 0-20 parts of soybean oil, 0-80 parts of bran, 8-12 parts of mountain flour, 10-15 parts of calcium hydrophosphate, 2-4 parts of amino acid, 0.2-0.5 part of vitamins, 2-3 parts of trace elements, 0.5-1 part of bacillus subtilis, 3-5 parts of sodium bicarbonate and 3-5 parts of edible salt. According to a sow compound feed disclosed by the invention, the phenomena of stillbirth, congenital deficiency and foetal mummification during sow farrowing are reduced; the birth weight of piglets is high, and the sizes of the piglets are uniform; the milk of the sows is sufficient, and the death rate of the piglets is low; the piglets grow fast, and the yellow and white scour of piglets is low; the weaned piglets in 25 days are 2.5 grams heavier than weaned piglets in a general factory; after the piglets are weaned, the sows are still basically fat; after the piglets are weaned for 4-7 days, the sows are heated.

Description

technical field [0001] The invention relates to a feed for pigs, in particular to a feed formula for improving the production performance of sows and a preparation method thereof. Background technique [0002] At present, the overall production level of China's pig industry is lower than that of foreign counterparts. The most obvious difference is that the annual contribution of piglets by sows is too small. Poor, and there are many losses in raising pigs. The few piglets contributed by sows are mainly due to the following reasons: firstly, the number of piglets produced is small, especially abnormal births, and there are few healthy piglets; secondly, the milk supply of sows is insufficient, and the survival rate of piglets is low; thirdly, sows are weaned and go into heat The abnormality reduces the annual parity; finally, the nutrition cannot keep up, the elimination rate of sows is high, and the phenomenon of empty pregnancy increases. These reasons directly lead to th...

Problems solved by technology

[0002] At present, the overall production level of China's pig industry is lower than that of foreign counterparts. The most obvious difference is that the annual contribution of piglets by sows is too small. Poor, more losses from raising pigs

The few piglets contributed by sows are mainly due to the following reasons: firstly, the number of piglets produced is small, especially the number of abnormal births is large, and there are few healthy piglets; secondly, the milk supply of sows is insufficient, and the survival rate of piglets is low; thirdly, sows are weaned and go into heat The abnormality reduces the annual parity; finally, the nutrition cannot keep up, the sow elimination rate is high, and the phenomenon of empty pregnancy increases

These reasons directly lead to the poor feed level of sows, which seriously restricts the production performance of sows.

[0003] At present, the sow feed of most feed manufacturers has the following problems after use: there are many stillbirths, weak fetuses, and mummified fetuses during sow production, that is, there are many stillbirths caused by dehydration after the death of piglet embryos in the sow’s uterus; low birth weight of piglets, Uneven size, insufficient sow milk, increased mortality of piglets; slow growth of piglets, severe yellow and white scour, low weaning weight; severe fat loss of sows after weaning; long-term non-estrus of sows after weaning
