How to breed laying hens, breeding methods, and techniques of laying hens

Laying hens refer to chickens that are raised to lay eggs to supply eggs. Eggs are the main source of income for laying hens. Different from broiler chickens, people raise laying hens mainly to improve egg quality and maintain or increase egg production, not to improve chicken quality. Scientific breeding technology is the prerequisite for the high yield of laying hens.

1. Before raising laying hens, choose a chicken house with good lighting and convenient ventilation. Summer is conducive to heatstroke prevention and cooling, and autumn, winter, and early spring are conducive to heat preservation and cold protection. Ensure that there is no sunshade in early spring, no wind protection in summer, and no water accumulation after rain. Take appropriate environmental protection measures to minimize environmental pollution.

2. Feeding method of laying hens

The weeks before parturition are the transition period for hens from the growing period to the laying period. At this stage, not only a series of tasks such as transfer to cages, selection and elimination, immunization, feed replacement, and increased light is required, which will cause great stress to the chickens. During this period, the physiological changes of the hens are severe, sensitive, and less adaptable. Weak and poor disease resistance, if the feeding and management are not proper, will easily affect the egg production performance.

Reasonable feeding. At present, most chicken farmers generally use full-price compound feed. Because chickens are used to eating feed, for example, some chicken farmers are used to feeding chickens with raw grains such as corn and rice, which not only reduces the utilization rate of feed but also is harmful to chickens. The correct feeding method is to crush raw materials such as corn, and then feed chickens with bran, bean cake, fish meal, and other raw materials according to the formula. At the same time, in daily feeding, it can be mixed with Vino layer hens to supplement multivitamins, promote growth rate, increase egg production rate, enhance resistance, and have good appetite performance. In winter, the proportion of high-energy feed should be increased, and protein should be appropriately reduced. content. Ensure chicken growth and egg production are functioning properly.

3.The feed can be reduced before laying eggs, or the concentrate can be reduced after laying eggs, and roughage can be supplemented for prevention.

In order to prevent calcium and phosphorus deficiency in caged laying hens, resulting in rough egg shells or egg shedding, and even death due to unsteady standing, you can add micronutrients in the feed to improve production performance and reduce sub-health If the situation occurs, increase resistance, improve growth, and strengthen the overall quality and growth uniformity of laying hens. Reduce the occurrence of deformities, wall licking, pica, immune decline, and slow growth. Improve the body shape and meat quality of laying hens, increase the laying rate of laying hens, increase egg weight, improve egg quality, and prolong the peak period of laying eggs. Help animal myoglobin and heme to form better, improve protein utilization and increase reproduction rate.

Immunization should be carried out before laying, and this immunization is very important to prevent the occurrence of blight during laying period. The immunization procedure is reasonable, in line with the actual situation of the field, the source of the vaccine is reliable, well preserved, the quality is guaranteed, the vaccination route is appropriate, the operation is correct, and the dose is accurate. After vaccination, the vaccination effect should be checked, and if necessary, antibody detection should be carried out to ensure the vaccination effect, so that the chickens have sufficient antibody levels to prevent the occurrence of diseases.

4. In winter, vitamin D should be supplemented under low temperatures and light conditions. It is necessary to ensure an uninterrupted and sufficient supply of clean drinking water, appropriately increase the feeding amount of green vegetables and improve the feeding capacity of laying hens. In the hot summer, we should pay attention to the supply of clean cold water, and we can also feed the crushed watermelon rind every day, which can not only prevent heatstroke in laying hens but also improve the egg production rate of laying hens. Don't drink cold water in winter, but give clean warm water, which can not only prevent laying hens from getting sick due to cold stomachs but also keep body heat.

2. Layer management

1. Laying hens are very sensitive to light, and good egg production can only be achieved by using the correct light. It can also stimulate the reproductive system to accelerate the development of ovaries. To promote the growth and development of chickens, the light time during the laying stage can only be increased but not shortened. The light required for laying eggs should not be less than 12 hours, and no more than 16 hours. It is best to increase the light at a rate of 15 minutes per week or half an hour every two weeks until 14-16 hours during the laying period. The length of the light is more important than the brightness of the lighting. When the lamp length reaches 14-16 hours, the time of turning on and off the lamp should be fixed to prevent the chicken from being stressed.

2. Strengthen epidemic prevention management. The environment, drinking water, and feed of the chicken coop should be kept clean. Chickens should be disinfected regularly inside and outside the chicken farm to reduce the occurrence of diseases. In addition, reasonable feeding of Vino compound probiotics can improve the reproduction of intestinal bacteria, enhance resistance, supplement active enzyme probiotics, regulate the balance of intestinal flora, protect intestinal health, and effectively prevent the occurrence of colibacillosis and mycoplasma disease.
