Problems solved by technology

At present, in terms of nutrition, a large amount of zinc oxide is usually added to the feed to control diarrhea in piglets. However, long-term feeding of high-zinc diets will inhibit the growth of piglets and reduce daily weight gain. On the other hand, a large amount of zinc will be excreted from the body through feces. caused serious pollution to the environment

Embodiment 1

[0019] A green feed additive for improving piglet diarrhea, which is composed of chitosan oligosaccharide and compound probiotics with a mass ratio of 1:10. Wherein, the composite probiotic is a composition of Bacillus subtilis, Bacillus licheniformis, Lactobacillus acidophilus and Lactobacillus lactis. The mass ratio of Bacillus subtilis, Bacillus licheniformis, Lactobacillus acidophilus and Lactobacillus lactis is 2:2:1:1.

[0020] The live bacteria content of each component is respectively: the live bacteria content of Bacillus subtilis ≥ 6 billion / g; Bacillus licheniformis ≥ 6 billion / g; Lactobacillus lactis ≥ 5 billion / g; Lactobacillus ≥ 4 billion / g; Lactobacillus ≥ 5 billion / g.

[0021] The feed additive was added to the diet according to 0.03% of the weight of the diet, and the weaned piglet experiment was carried out.

[0022] Healthy and disease-free Dudu piglets at about 21 days old with basically the same initial weight were selected for the feeding test. The test...

Abstract

The present invention relates to a feed additive for reducing diarrhea rate of piglets, belongs to the technical field of animal feeds and is applied to the livestock breeding industry. The green feed additive for reducing the diarrhea rate of piglets is composed of chitosan oligosaccharide and a complex probiotic, wherein the mass ratio of the chitosan oligosaccharide to the complex probiotic is in a range of 1:5 to 1:20. The complex probiotic is a composition which is prepared from bacillus subtilis, bacillus licheniformis, lactobacillus acidophilus and lactobacillus lactis. According to the invention, the feed additive contains no heavy metal and is low in required adding amount. The feed additive is environment-friendly since no toxic and side effect is caused to the piglets and no residue is left after use. The feed additive can reduce the diarrhea rate of the piglets and can significantly promote piglet growth at the same time.

Description

technical field [0001] The invention relates to a feed additive for improving the diarrhea rate of piglets, which belongs to the technical field of animal feed and is applied to the animal husbandry industry. Background technique [0002] In the current pig production, piglet diarrhea is more common. Due to the imperfect development of the structure and function of the gastrointestinal tract of piglets, the particularity and some defects of its digestive physiological system are caused. Piglets grow fast, have strong material metabolism, and have a strong demand for nutrients, but the regulation function is not perfect, and the resistance to various stresses is poor, so piglets are prone to diarrhea. In actual production, the diarrhea rate of piglets is generally 20% to 30%, and the mortality rate is 2% to 4%. At present, in terms of nutrition, a large amount of zinc oxide is usually added to the feed to control diarrhea in piglets. However, long-term feeding of high-zinc ...
