Anti-stress compound premix feed for laying fowls as well as preparation method and application of anti-stress compound premix feed

Abstract

The invention relates to an anti-stress compound premix feed for laying fowls as well as a preparation method and application of the anti-stress compound premix feed. The premix feed is composed of the following raw materials in parts by weight: 160-240 parts of citric acid, 80-160 parts of fumaric acid, 8-15 parts of a plant essential oil compound, 2-5 parts of 25-hydroxy cholecalciferol, 0.15-0.75 part of ammonium sulfate nitrate, 6-15 parts of nicotinamide, 0.2-0.5 part of riboflavin, 0.2-0.5 part of D-calcium pantothenate, 1-2 parts of pyridoxine hydrochloride, 20-36 parts of DL-alpha-tocopheryl acetate, 0.4-0.7 part of menadione sodium bisulfite, 1-4 parts of biotin, 0.3-0.9 part of vitamin B12, 10-30 parts of phytase, 1-5 parts of protease, 2-10 parts of DL-methionine, 20-60 parts ofselenium yeast, 50-150 parts of calcium hydrophosphate and 200-600 parts of a carrier. The premix feed provided by the invention can significantly improve the stress intestinal injury of the laying fowls and improve the digestive absorption capacity, and finally achieves the effects of relieving the stress of the laying fowls, reducing the dirty egg rate, improving the egg laying rate in a stressstate, improving the egg quality and the breeding performance of breeding fowls, reducing the dirty egg rate, improving the fertilization rate and the hatching rate and increasing the economic benefits of farmers.

Description

technical field [0001] The invention belongs to the technical field of poultry nutrition and regulation, and in particular relates to an anti-stress compound premixed feed for laying poultry and its preparation method and application. [0002] technical background [0003] In the process of modern intensive poultry farming, many stresses will be encountered, such as cold and heat stress, etc. There are many reasons for stress, such as transportation, temperature changes, feeding, deworming, exposure to antibiotics and others Chemicals, bacteria, viruses and parasites, vaccinations, beak trimming, overcrowding, suboptimal farm conditions and more. These factors place the chicken in a state of stress at all times throughout its life, adversely affecting growth, production and in vivo feed conversion efficiency. Especially for laying poultry, the laying period itself is a kind of physiological stress. The ovulation process will produce a large amount of ROS (oxygen free radical...

Problems solved by technology

Stress usually mediates the necessary adaptive regulation by regulating the secretion of catecholamine hormones and glucocorticoids via the coeruleus-sympathetic-adrenomedullary axis and the hypothalamic-pituitary-adrenal cortex axis. Regulating energy balance to cope with energy challenges caused by stressors is important for improving stress adaptation, but it will cause insufficient energy for production and reproduction, and it will also cause harm to the body's health, causing gastrointestinal Ischemic damage, oxidative stress damage to intestinal wall cells and liver cells, triggers inflammation in the body, reduces immunity, thereby increasing animal susceptibility to diseases, reducing animal production efficiency, and failing to fully develop genetic potential
