The invention relates to the technical field of preparation of feed additives, in particular to a traditional Chinese medicine compound feed additive for preventing stress syndromes of early weaned piglets and a preparation method of the traditional Chinese medicine compound feed additive. The medicine specifically comprises the following components: rhizoma osmundae, astragalus membranaceus, mangnolia officinalis, hawthorn, medicated leaven, pericarpium citri reticulatae, polygala tenuifolia, Chinese pulsatilla root, cortex fraxini, poria cocos, liquorice and spina date seed. The traditional Chinese medicine compound feed additive provided by the invention has a remarkable technical effect in the aspect of preventing the early-stage weaned piglet stress syndrome. Through scientific compatibility of various traditional Chinese medicine components, the additive can effectively improve the digestive function of the weaned piglets, enhance the immunity, relieve the stress response and remarkably reduce the diarrhea rate and the death rate. Experimental results show that piglets using the additive are superior to a blank control group and other substitution groups in the aspects of weight gain, oxidation resistance, serum hormone level, immune globulin indexes and the like, and the additive is proved to have a comprehensive physiological regulation function.

The application belongs to the technical field of biological medicine, and particularly relates to a medium-chain fatty acid composition for improving immunity of calves and a preparation method thereof. The medium-chain fatty acid composition for improving immunity of calves according to the application comprises, in terms of weight fractions, 20-30 parts of lactose, 5-10 parts of medium-chain fatty acid, 1-3 parts of mangiferin derivative, 0.5-2 parts of wedelolactone and 0.2-1 part of vitamin C. The mangiferin derivative according to the application can relieve local inflammatory reaction of the intestinal tract, repair the intestinal mucosal barrier damaged by stress, and enhance the non-specific immune capacity of the body. The wedelolactone according to the application forms a double synergy with the lactose and the medium-chain fatty acid, greatly improves the utilization efficiency of energy and nutrients, and thus promotes the growth and development of the calf. In addition, the wedelolactone can also synergize with the mangiferin derivative, maintains the intestinal health of the calf in the early weaning period, and significantly weakens the weaning stress impact.

The invention discloses application of beta2M as a biomarker in early weaning stress of animals, and belongs to the technical field of detection and analysis. According to the application of the beta2M as the biomarker in preparation of a product for detecting the early weaning stress of animals, the product is used for detecting the content of the beta2M in jejunum tissues or serum samples and can be used for judging whether the animals have weaning stress symptoms or not. The invention provides a new biomarker for prevention, diagnosis and treatment of animal weaning stress intestinal injury.

The invention provides a rhizoma polygonati polysaccharide extract weaned piglet feed additive and application thereof.The feed additive comprises a rhizoma polygonati polysaccharide extract, and the rhizoma polygonati polysaccharide extract comprises, by mass, 36%-49.8% of rhizoma polygonati polysaccharide, 3%-12% of saponin, 2%-8% of flavone, 30%-45% of total amino acid and 0.2%-1% of alkaloid. Polygonatum sibiricum polysaccharide has various pharmacological activities such as anti-inflammation and bacteriostasis, immunity regulation, tumor resistance, oxidation resistance, blood sugar and blood fat reduction and the like, the polygonatum sibiricum polysaccharide extract is reasonably added into weaned piglet basic feed breeding, and the application dosage of the polygonatum sibiricum polysaccharide extract is 150-600 mg per kg of weaned piglet basic feed; the feed antibiotic can replace feed antibiotics, and can effectively reduce the diarrhea rate of weaned piglets, regulate the intestinal flora structure and improve the abdominal and intestinal morphology of the weaned piglets, so that the survival rate of the weaned piglets in the early stage is increased, the breeding cycle of a farm is shortened, and the reproductive performance is improved.

This invention discloses the application of pharmaceutical by-products from Isatis indigotica, belonging to the field of livestock breeding technology. The application of these by-products involves regulating the intestinal flora of piglets, improving liver function, or improving lipid metabolism in piglets. This invention utilizes Isatis indigotica by-products to regulate the intestinal flora, improve liver function, or improve lipid metabolism in piglets. After weaning, this effectively improves intestinal flora imbalance, liver damage, and glucose and lipid metabolism disorders caused by early weaning stress in piglets, thereby effectively reducing adverse stress responses during weaning, improving piglet health, and increasing breeding efficiency.
