The onset of egg laying by a hen is a sign of puberty completion and sexual maturity, and the age of the day for laying the 1 st egg is generally called the age of the sexual maturity day of the hen. The conventional laying hens are fed with common feed, the laying hens are fed with the common feed in a conventional feeding mode, the feed ingredients of the laying hens per day are the same, the laying quality of the laying hens is reduced day by adopting the feeding mode, the physique of the laying hens is gradually reduced due to unbalanced nutrition or insufficient nutrition of the laying hens, the resistance of the laying hens to viruses and environment is gradually reduced along with the increase of the laying time, the laying time of the laying hens is shortened, and the number of the laying hens is gradually reduced due to the fact that the laying hens start to gradually lose weight and are infected with diseases such as germs. Therefore, the development of a method for improving the egg laying quality of the laying hens under the condition of ensuring the physique of the laying hens is urgently needed.
The invention content is as follows:
the invention aims to overcome the defects of the prior art and provide the method for improving the egg laying quality of the laying hens.
The technical scheme adopted by the invention is as follows: a method for improving egg quality of a laying hen, the method comprising the steps of:
step one, adjusting the environment: controlling the temperature of the henhouse at 15-25 ℃, controlling the humidity of the henhouse at 60-75%, illuminating the henhouse for 15-18h every day, and spraying a disinfectant into the henhouse every day; the illumination is in an uninterrupted illumination mode for 15-18h, the illumination intensity of each square meter in the henhouse is controlled to be 8W-15W, the henhouse is cleaned every morning, and a disinfectant is sprayed into the henhouse, wherein the dosage of the disinfectant is 5mL-10mL per square meter;
step two, laying hen breeding: feeding laying hens 4 times a day in the laying hen breeding process, and changing drinking water 3 times a day; the time for feeding the laying hens for the first time is 6-7 o' clock in the morning every day, the time interval between the time for feeding the laying hens for the second time and the time for feeding the laying hens for the first time is 3-4h, the time interval between the time for feeding the laying hens for the third time and the time for feeding the laying hens for the second time is 5-6h, and the time interval between the time for feeding the laying hens for the fourth time and the time for feeding the laying hens for the third time is 6-7 h. The time for replacing the drinking water for the first time is 6-7 o' clock earlier every day, the time interval between the time for replacing the drinking water for the second time and the time for replacing the drinking water for the first time is 6-7h, and the time interval between the time for replacing the drinking water for the third time and the time for replacing the drinking water for the second time is 6-7 h. The four-time feeding mode can ensure the daily nutritional requirements of the laying hens and arrange and construct the diet structure of the laying hens in a balanced manner according to the activity and egg production of the laying hens. The feed is fed for four times, so that the absorption rate of the laying hens on the nutrient components in the feed can be improved, and the waste of the nutrient components in the feed is avoided.
Step three, enhancing the disease resistance of the laying hens: adding disease-resistant agent into drinking water every day from 5-15 days before egg laying of the layer chicken to the end of the egg laying period, wherein the addition amount of the disease-resistant agent is 0.05% -0.1% of the drinking water amount.
The disinfectant comprises, by weight, 1-5 parts of lactobacillus, 7-8 parts of sea buckthorn, 1-3 parts of nitrobacteria, 7-10 parts of photosynthetic bacteria, 2-10 parts of 2-methyl-5-nitroimidazole-1-ethanol, 1-5 parts of pyrethrum album, 7-15 parts of sodium acetate and 80-120 parts of water. The disinfectant realizes the disinfection and sterilization of organic waste in a henhouse while decomposing into small molecules beneficial to laying hens by matching photosynthetic bacteria, lactobacillus and nitrobacteria microorganisms with 2-methyl-5-nitroimidazole-1-ethanol, pyrethrum alba, sodium acetate and the like, purifies the environment of the henhouse, keeps the henhouse clean, avoids breeding of mosquitoes, germs and the like, simultaneously realizes the mutual matching action of the pyrethrum alba, the 2-methyl-5-nitroimidazole-1-ethanol and the sodium acetate, destroys the cell walls of the germs, avoids breeding of the germs from the root source, has no toxic or side effect, simultaneously can degrade feed residue in the henhouse, excrement of the laying hens and other organic matters by the mutual matching action of the lactobacillus, the photosynthetic bacteria and the nitrobacteria, and can absorb and utilize ammonia in the henhouse, Nitrite, hydrogen sulfide and other harmful substances can prevent the layer chicken from getting ill and reduce the death rate of the layer chicken. The preparation method of the disinfectant comprises the steps of mixing and boiling the sea buckthorn, the white chrysanthemum and water for 1 hour, filtering to remove residues of the sea buckthorn and the white chrysanthemum, keeping filtrate, cooling the filtrate to room temperature, adding sodium acetate and 2-methyl-5-nitroimidazole-1-ethanol into the filtrate, stirring and mixing uniformly to prepare a mixed solution, adding lactobacillus, nitrobacteria and photosynthetic bacteria into the mixed solution after mixing uniformly, and mixing to prepare the disinfectant.
