Laying hen feed capable of alleviating heat stress and preparation method thereof

Abstract

The invention provides a laying hen feed which is capable of alleviating heat stress. The laying hen feed is composed of the raw materials including, by weight, 28-32 parts of corn, 18-22 parts of rice, 8-12 parts of bran, 2-3 parts of fishmeal, 13-18 parts of soybean meal, 8-12 parts of grass meal, 8-10 parts of corn husk, 3-5 parts of stone powder, 0.3-0.5 parts of corn oil, 1-2 parts of calcium hydrogen phosphate, 0.2-0.3 parts of lysine (65%), 0.15-0.18 parts of DL-methionine, 0.01-0.02 parts of L-threonine, 0.03-0.05 parts of a composite enzyme preparation, 15-20 parts of carrots, 4-6 parts of loofah flower, 2-3 parts of bear gall powder, 3-5 parts of dandelion, 2-4 parts of rhizoma alismatis, 3-5 parts of platycodon grandiflorum, 3-5 parts of houttuynia cordata, 2-3 parts of chicory roots, 2-3 parts of flower of cleistocalyx operculatus, 2-4 parts of hypericum japonicum, 6-8 parts of sechium edule, 4-6 parts of kelp, 8-10 parts of trichosanthes kirilowii seeds, 10-12 parts of barley and a proper amount of salt. The laying hen feed has abundant nutrients and is low in cost.

Description

technical field [0001] The invention relates to a chicken feed, in particular to a laying hen feed that can relieve heat stress and a preparation method thereof. Background technique [0002] Eggs are one of the best nutritious foods for human beings. Eggs contain a lot of vitamins and minerals and proteins with high biological value. For humans, the protein quality of eggs is the best, second only to breast milk. The proportion of amino acids in egg protein is very suitable for the physiological needs of the human body, easy to be absorbed by the body, the utilization rate is as high as 98%, and the nutritional value is very high. Eggs are high in calcium, phosphorus, iron and vitamin A, and are also rich in B vitamins. They also contain many other vitamins and trace elements necessary for the human body. Good supplement for convalescent patients. However, eggs contain high levels of triglycerides and total cholesterol. Eating eggs frequently will cause high blood cholest...

AI Technical Summary

Problems solved by technology

However, eggs contain higher triglycerides and total cholesterol. Eating eggs frequently will cause excessive blood cholesterol levels, cause atherosclerosis and the occurrence of heart and cerebrovascular diseases, and affect human health.

In addition, in order to prevent diseases of laying hens and improve the production performance of laying hens, chicken breeding companies generally add antibiotics, hormones and chemical synthetic drugs to laying hen feed. After long-term consumption of such feed, laying hens are prone to induce pathogens to produce antibodies and drug loss. Active enzymes can change cell membrane permeability or protoplasmic metabolic process, resulting in drug resistance and drug residues in laying hens, posing a potential threat to human health
