Additive containing xylooligosaccharide and preparation method

Abstract

The invention relates to an additive containing xylooligosaccharide and a preparation method thereof. The additive is prepared from the following raw materials: 1-5g of xylooligosaccharide; 1 * 10 < 10 >-3 * 10 < 10 > CFU of active yeast; 3-7g of zinc lactate; 2 to 6 g of trehalose; 0.5 to 0.8 g of pomegranate flower extract; and 0.3-0.5 g of hemi-ammonium salt. The feed additive prepared by compounding the oligoxylan, the active yeast, the zinc lactate, the pomegranate flower extract, the hemi-ammonium salt and the trehalose is mixed with a sow feed, so that the feed intake of sows can be effectively increased, the nutrition supply required by the lactation period of the sows is met, the mammary gland development of the sows is promoted, the lactation capability is improved, and the lactation period of the sows is prolonged. The resistance of the sows can be improved, the heat stress resistance of the sows is enhanced, and then the lactation yield of the sows is increased.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to an additive containing xylooligosaccharide and a preparation method thereof. Background technique [0002] The milk production of lactating sows in the whole period determines the production performance of suckling piglets, and the milk production of lactating sows decreases significantly in summer, which leads to increased mortality of piglets during lactation, decreased body weight of weaned piglets, increased diarrhea rate of weaned piglets, A series of problems such as decreased vitality of weaned piglets. There are two main reasons for the decrease in milk production of lactating sows in summer. One is that sows are easily affected by heat stress in summer, which leads to different degrees of endocrine disorders in lactating sows, resulting in a decrease in feed intake, which in turn leads to a decrease in milk synthesis efficiency. Second, the excrement of sows and ...

There are two main reasons for the decrease in milk production of lactating sows in summer. One is that sows are easily affected by heat stress in summer, which leads to different degrees of endocrine disorders in lactating sows, resulting in a decrease in feed intake, which in turn leads to a decrease in milk synthesis efficiency. Second, the excrement of sows and piglets contains a large number of harmful bacteria, which leads to poor sanitation of the sows' production environment, and the sows are prone to infection and disease after delivery, which in turn leads to sows' lactation Decreased ability; and will affect the survival rate of piglets

[0003] At present, aiming at the problem of feed intake of sows, the feed intake of sows is often improved by improving the feed formula and adding additives such as feed attractants, but the effect is not ideal, and it cannot effectively inhibit the excrement of sows. Harmful bacteria in the pig can multiply, thereby improving the hygiene of the sow production environment
