Technical Field

The invention relates to the technical field of biology and new medicines, in particular to a preparation method of a feed for prolonging the peak period of high yield of laying hens.

Background

China is the world with the largest laying hen feeding amount and egg yield, and with the development of scientific breeding technology, in order to further improve breeding benefits, the adjustment of the traditional breeding structure in China is imperative, and the technical level needs to be improved urgently. Domestic laying hens generally lay eggs at 18-19 weeks old, the laying rate reaches 50% at 23-25 weeks old, the laying hens enter an egg laying peak period (the laying rate is more than 90%) at 27-29 weeks old, and the maximum laying rate can reach more than 95%. The egg laying peak period generally lasts for about 20 weeks (5 months).

The scale of the laying hens in western developed countries represented by the United states is enlarged in the foreign country, the production units are reduced, and the egg laying performance is high. According to the statistics of the American sea blue company, the given sea blue brown production data is combined with the Chinese market production data: more than 90% of eggs are kept for more than 6 months, 21KG is produced, eggs are laid from 18 weeks old and are eliminated from 79 weeks old, 21KG is laid in total, and about 340 eggs are laid.

In the future, the breeding of laying hens is continuously shifted from a large group without specialization on a small scale to a small group with a large scale and specialization, the total breeding amount is stable day by day, the professional ability of practitioners is stronger and stronger, the quality of the practitioners is higher and higher, the number of the practitioners is less and less, the egg laying performance of the laying hens is further improved, and the high yield and the stable yield can reach 8-9 months.

The purpose of laying hen breeding is to improve the production performance of laying hens to the maximum extent, so that the egg laying peak period is prolonged, the egg yield is increased, and the best economic benefit is obtained. However, in the breeding process, the production performance of the laying hens cannot be fully exerted, and the expressed production levels are different, so that the egg laying peak period of the laying hens is prolonged by reasonably improving the feed formula, strengthening the feeding management and taking practical and effective measures. Prolonging the egg-laying peak period is one of the most concerned problems for farmers, because it is one of the important factors related to the income of farmers. Two indexes are provided for measuring the egg laying peak of laying hens, namely the number of peaks, and the time for which the peaks can be maintained.

(III) the technical level and market prospect reached by the project

Aiming at the problems that the laying hens have high requirements on the nutrient concentration in daily ration in the egg laying peak period and the nutrient supply needs to be sufficient when the egg laying peak period is maintained for a long time: high-quality feed raw materials are selected in the egg-laying peak period, and the adjustment of the nutrient concentration is carried out according to the change of the feed intake, wherein the important point is to grasp the content change of two major factors of energy and protein. Energy: is an important nutritional factor for the full play of the production level of the laying hens, so the importance of energy is important. Calcium: in addition to paying attention to energy and protein requirements, the calcium level in the ration is also increased to meet egg production needs. A microecological preparation: the balance of intestinal flora of the laying hens is adjusted, the digestion and absorption of nutrient substances such as calcium, phosphorus and vitamins are promoted, the quality of eggs is improved, and probiotics: intestinal health is the basis for chicken flock health. Only has good intestinal tract, and the feed is easy to absorb and convert, so that the food drinking water is clean and nontoxic, the diarrhea of the chickens is reduced, and the autoimmunity of the chickens is enhanced. Vitamins: the laying hens have more stress reaction factors, and the addition amount of the multiple vitamins is reasonably increased before the expected stress factors.

By scientifically and reasonably improving the feed formula, the laying rate of the chicken group can be obviously increased, the egg laying peak period is prolonged, the eggshell quality is improved, the whole egg laying peak period can be maintained for 8-9 months, and 10-15 yuan is earned by each chicken.
