Feed additive for relieving immune stress of piglets, preparation method thereof and application thereof

Abstract

The present invention relates to the technical field of feed additives and particularly relates to a feed additive for relieving immune stress of piglets, a preparation method thereof and an application thereof. The feed additive for relieving the immune stress of the piglets comprises 3.0 parts of compound Chinese herbal medicines, 2.0 parts of glutamine and 1.0 part of tea polyphenol; and the compound Chinese herbal medicines are composed of the following traditional Chinese medicinal materials: 20 parts of rhizoma anemarrhenae, 12 parts of hierochloe odorata, 12 parts of borneol, 18 parts of red paeony roots, 14 parts of fossilia ossis mastodi, 18 parts of dried rehamnnia root, 25 parts of honeysuckles, 8 parts of felwort, 20 parts of heartleaf houttuynia herb, 12 parts of common andrographis herb, 12 parts of acanthopanax roots, 10 parts of szechuan lovage rhizome, 8 parts of pilose asiabell root, 15 parts of platycodon grandiflorum and 8 parts of pseudo-ginseng. The additive can alleviate the immune stress of the piglets caused by normal vaccine immunization, improves daily feed intake and daily weight gain of the piglets during the immune stress, and reduces a feed-to-meat ratio.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive for relieving immune stress of piglets, a preparation method and application thereof. Background technique [0002] Immune stress, also known as immune stimulation, refers to the injection of antigens to stimulate immune responses in immunology. During an animal's life, many factors, including various infections, trauma, and internal tumors, can cause immune stress. During the growth process of pigs, they are often stimulated by pathogenic or non-pathogenic microorganisms, vaccines and heterologous proteins, and are in a state of immune stress, which affects the production performance and health status of pigs. Many studies have confirmed that immune stress reduces livestock feed intake, feed conversion rate, time to market, protein deposition, carcass lean meat percentage, and eye muscle area. For example, vaccine immunization is to prevent specific dise...

Problems solved by technology

For example, vaccine immunization is to prevent specific diseases of pigs, and the pigs are injected with low-activity or inactivated viruses or bacteria, but vaccine immunization can also cause immune stress in pigs and reduce the production performance of pigs. How to alleviate the immune stress of pigs , to improve the production performance of pigs during the immune stress period, which is of great significance to pig production

[0003] Chinese patent CN106880733A discloses an additive (weaning protection powder) that reduces the stress of weaned piglets. CN103315184B discloses a feed additive that alleviates the adverse effects of transportation stress on piglet growth. There is no disclosure in the art to alleviate piglet immune response.
