Feed additive for preventing or alleviating toxin infection of piglets during weaning period and preparation method thereof

Abstract

The invention discloses a feed additive for preventing or alleviating endotoxin infection of piglets after weaning and a preparation method thereof, belonging to the field of feed additives. The invention firstly discloses a feed additive for preventing or alleviating endotoxin infection of piglets after weaning, which comprises the following components: baicalin, taurine and lipoic acid. The invention also discloses a method for preparing the feed additive, which includes: weighing each component according to the weight ratio, and mixing to obtain. The feed additive of the present invention can significantly reduce the blood endotoxin content of piglets caused by weaning stress, effectively increase the number of red blood cells, the total number of white blood cells and the number of lymphocytes of weaned piglets, improve the vitality and immune resistance of piglets before and after weaning, and promote the growth and development of weaned piglets. growth, and effectively alleviate the stress brought by weaning to piglets; in addition, the feed additive of the present invention has definite anti-diarrhea effect.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for preventing or alleviating toxin infection in the weaning period of piglets. The invention also relates to a preparation method and application of the feed additive, belonging to the field of feed additives in the weaning period of piglets. Background technique [0002] In livestock and poultry farming, diarrhea, edema, and endotoxic shock are common diseases in weaned piglets, and these diseases generally occur in piglets about 10 days after weaning. As piglets are stimulated by various stress factors after weaning, the immune function of the body is reduced, causing a large number of pathogenic bacteria to multiply. These pathogenic bacteria are adsorbed on the small intestinal villi and release a variety of toxins, such as enterotoxin, endotoxin, etc. , The toxin is absorbed into the blood through the intestinal tract and causes toxemia, enterotoxin causes post-weaning dia...

Problems solved by technology

[0004] The current clinical routine treatment is to use antibiotics to inhibit or kill pathogenic bacteria, but antibiotics kill harmful bacteria as well as beneficial bacteria, causing the imbalance of flora, intestinal wall epithelial cell ulceration, and loss of intestinal barrier function , the killed Gram-negative bacteria and disintegrated endotoxins enter the body in large quantities, and migrate to various organs with the blood, causing dysfunction of various organs, generating systemic inflammatory reactions, and then triggering multiple organ dysfunction syndrome
