Raising method for selenium-enriched laying hens

Abstract

The invention provides a raising method for selenium-enriched laying hens, and belongs to the technical field of stock farming. The raising method comprises the steps that firstly, a raising pond is selected, a henhouse with a ventilation device and an illumination device is built, laying hens are divided into a brood period, a growing period and a laying hen period according to different weak ages to be raised separately, the laying hens are fed with disease-prevention liquid medicine periodically, and feed of the laying hens is prepared from maize meal, bean pulp, wheat bran, smashed soybeans, pinecone powder, snail shell powder, bone meal, mountain flour, additives and plant extractives. The invention further provides a manufacturing method of the feed of the laying hens. The feed adopted by the raising method is formed by scientific combination, the feed contains abundant bioactivators, the effective components of the raw materials affect each other, the synergistic effect is achieved, laying hen feeding can be promoted, the immunity of the laying hens is improved, the disease incidence rate is decreased, the nutritive value of the laid eggs can be increased, the eggs contain various nutrient substances including the selenium element, and therefore the earnings of a farmer can be increased.

Description

【Technical field】 [0001] The invention relates to the technical field of animal husbandry, in particular to a breeding method for selenium-enriched laying hens. 【technical background】 [0002] Eggs are the daily necessities of people's life. Every 100 grams of eggs contain 12.8 grams of protein, mainly ovalbumin and ovalbumin, which contain 8 kinds of amino acids necessary for the human body, and are very similar to the composition of human protein. Human body absorbs egg protein The rate can be as high as 98%. Every 100 grams of eggs contains 11-15 grams of fat, which is mainly concentrated in the egg yolk, which is also easily digested and absorbed by the human body. The egg yolk is rich in lecithin, sterols, calcium, phosphorus, iron, vitamin A, vitamin D and B vitamins. These ingredients are of great benefit to improving the function of the nervous system. Therefore, eggs are a good brain food. [0003] At present, the chicken industry occupies an important position i...

Problems solved by technology

[0003] At present, the chicken industry occupies an important position in the entire national economy, but in recent years, with the increase of free-range farmers, problems have continued to increase, such as unreasonable feed ratio during egg production, high death rate, and short peak period. The rate of decline in the later stage is fast; blindly mixing drugs and abusing antibiotics during the brooding period, resulting in antibiotics in chicken and eggs, and poor quality; the ability to distinguish commercial feed is not strong, and the nutrition provided by the feed is not balanced; After the chicken flocks get sick, most of the free-range farmers cannot give symptomatic treatment at the first time of the onset, resulting in large losses
