Broiler anti-vaccine immune stress agent and application thereof

Abstract

The invention discloses a broiler anti-vaccine immune stress agent and application thereof. The stress agent is prepared from, by mass, 2.5% to 5% of rhizoma curcumae longae, 2% to 4% of astaxanthin,2.5% to 5% of Isomaltooligosaccharide, 2.5% to 5% of threonine, 2% to 3% of methionine, 1% to 1.5% of compound multi vitamin and 76.5% to 87.5% of a carrier. The aim of the stress agent can also be achieved by preparing functional complete feed or concentrates and premix of broiler anti-vaccine immune stress. The body immune function can be enhanced by relieving neuroendocrine disorder, improvingthe multiplication capacity of splenic lymphocyte, reducing lymphocyte of the splenic lymphocyte and remarkably improving the antibody level of broilers subjected to vaccine immunity, the appetite ispromoted, and the growth performance is improved. The method is convenient for preparation use, and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of animal health care and bioimmune medicine, and relates to a broiler anti-vaccine immune stress agent and application thereof. Background technique [0002] With the continuous improvement of broiler breeding technology, fast-growing broilers meet people's needs. However, chickens of these breeds exhibit weaker immune responses, high morbidity and mortality in stressful environments. A moderate immune response helps animals resist diseases, but when the body is stimulated by bacteria, viruses and endotoxins in the environment or vaccinated, the animal makes an adaptive response in order to maintain the body's homeostasis, through the hypothalamus-pituitary-adrenal gland The (HPA) axis and the sympathetic nervous system (SNS) regulate and release stress hormones, such as adrenocorticotropic hormone (ACTH) and corticotropin-releasing hormone (CRH), which highly activate the immune system, especially oversecretion It...

Problems solved by technology

[0004] Although there are also some anti-stress medicaments in the prior art, which have certain effects on anti-stress, many products are limited to Chinese herbal medicines or their extracts, vitamins and other compositions, and have unstable anti-stress effects and poor effects. At the same time, these products are not limited to poultry, especially broiler chickens, and broiler chickens have their own immune central organs, so they also have certain specificity. However, so far, there is no anti-vaccine specifically for broiler chickens in the prior art. Reports on immune stress agents
