The egg laying rate of more than 90% is known as the peak period of egg production. The length of its duration is closely related to the total egg production. According to the law to extend the egg laying peak period, get better economic benefits.
First, pay attention to the cultivation of broilers
1. Select high-yielding layer chicken breeds. Achieve better egg production peaks.
2. Keep young hens healthy and tidy. Breeding hens have a good body weight, strong bones, and muscular development, and can obtain high egg production peaks. Application of scientific breeding methods, so that the layers of chickens at each stage of body weight or control of excessive body weight in the 5% to 10%, and keep the individual chickens uniform, for the layer quickly into the egg production peak and keep egg production peak for a long time to lay basis.
3. Reasonably choose the brooding season. In the winter of June to August, chicks who eat in the winter season are just at the peak of production. The combination of high temperatures and high humidity will cause the flock to reach the peak of egg production due to insufficient feed intake, and it will also result in a drop in egg weight and weight loss. Therefore, it is advisable to arrange laying hens to grow in spring and summer, and to start production in autumn. This will ensure that the high egg production rate of the chickens and the amount of egg production will be maintained, and that the peak period of egg production can be maintained for a long time.
Second, control the breeding environment
1. A reasonable lighting system. Illumination has the effect of stimulating gonads on egg-laying hens to promote ovulation, and increasing light time can promote egg production. Prolonged exposure to light should be based on body weight at 17 weeks of age and the degree of sexual maturity. The weight of the chicken population should reach the standard 15 to 30 minutes per week, until the increase to 16 hours after the constant; do not rush to prolong the light to reach the standard, the fill time can be postponed by 1 week. The light intensity is controlled at 7.5 to 10 lux.
2. The appropriate temperature and humidity. The suitable temperature for layer production is 23-28°C. During the peak season of egg production, summer cooling and winter insulation work should be done. The relative humidity of the house should be kept between 60% and 70%.
3. Keep the house air fresh. The carbon dioxide concentration in the laying hen house should be less than 0.3%, the ammonia concentration should be less than 0.0015%, and the hydrogen sulfide concentration should not exceed 0.001%. First of all, we must maintain a good ventilation of the shed, strengthen ventilation, in the winter to correctly handle the relationship between insulation and ventilation, do a good job of cleaning and reduce chicken dwelling time in the chicken house. The appropriate stocking density should be mastered. Shallow cage type cages feed 3 to 4 chickens per cage, which can better exert the laying performance of chickens.
4. Prevent stress. All kinds of stress such as harassment, scaring, and water shortage will cause the egg laying rate to drop, and shorten the duration of egg production peak. In this regard, electrolysis can be added to drinking water in multidimensional or double supply of multivitamins. In addition, create a quiet breeding environment.
Third, strengthen feeding management
1. Meet the nutritional needs of laying hens. The laying hens at the peak of egg production have higher requirements for nutrition, and should provide comprehensive nutrition, high quality, and good palatability in the production of egg-laying compound feeds, mastering metabolic platform giant intake of 1.25 to 1.42 MJ/(day only), crude protein Intake 18 to 20 grams / (days only). The content of minerals and vitamins should be properly increased in the feed, and particular attention should be paid to the addition of granular calcium. The suitable content of calcium in the layer feed for laying is 3.2% to 3.5%, and the available phosphorus is 0.41% to 0.35%. Attention should be paid to calcium before use. The principle of low post high and high phosphorus consumption before high and low.
2. Reasonably supply feed. The feeding of laying hens at the peak of egg production should meet the requirement of high yield as much as possible, and the number of feeds should be appropriately increased to encourage the birds to eat more food. However, the increase in feed intake during the late peak period should be cautious. Excessive feeding will result in excess nutrients, which can easily lead to fatty liver, rectal prolapse, and abdominal cavity production.
3. Provide clean drinking water. Fresh drinking water must be constantly supplied. If the laying hens are cut off for 24 hours, the egg production will be reduced by 30% and 30 days after the replenishment, the production will resume; if the water is cut off for 48 hours, it will cause serious death. As the amount of water consumed by chickens increases with the temperature and the rate of egg production, clean drinking water should be maintained uninterrupted during the hot season or high-yield period.
Fourth, correct prevention and control of diseases
Adhering to the principle of “giving priority to prevention and focusing on preventionâ€, the establishment of a strict health and disease prevention system is another important measure to maintain the egg production peak of laying hens. The immunization of important diseases prior to the start of production is a necessary measure to ensure a higher rate of egg production and to maintain a good peak of egg production. Newcastle disease vaccines, transmission H120 vaccines, infectious laryngotracheitis vaccines, inactivated chronic respiratory inactivated vaccines, inactivated egg drop syndrome vaccines, and inactivated infectious rhinitis vaccines were used at different ages. After the chicken is opened, electrolytic cubes are often used. When the flock is threatened by a certain disease or must be treated when there is a pathological condition, drugs should be carefully selected, such as sulfonamides or sulfonamide synergists, aminophylline, chlortetracycline, amantadine, etc. must be disabled so as not to inhibit and damage chickens. Reproductive system, resulting in decreased egg production. Regular disinfection should be done. Workers in the production area and the surrounding environment must also be strictly sterilized. Garbage, chicken waste, and waste should be promptly removed for harmless treatment. Closed rearing is adopted to prevent the introduction of foreign sources.
