Laying hens must produce high yields and grasp the "six" key

First, improve the uniformity of spare chickens

The success of cultivating spare chickens is an important indicator of their uniformity. Small differences in body size, flock development, sexual maturity can be synchronized, in the future to open the production time can be consistent, the peak egg production is also high. In the management, efforts are made to increase the uniformity of the chicks. In addition to scientific management in aspects such as temperature, humidity, feed, density, and immunity, it is necessary to pay attention to keeping strong and weak chicks separately and strengthen nutrition for weak chicks. First of all, the stocking density should be moderate, and the environmental conditions caused by the excessive breeding density should be eliminated. The average material level and water level of the chickens should be insufficient, which affects the uniformity of the broiler chickens. Second, according to the weight of timely grouping, divided into large, medium and small groups, the necessary restrictions on the overweight groups feeding, for small groups of people are reasonable feeding, in order to reduce the difference in the weight of the whole group, to achieve the same open weight.

Second, reserve chicken body important standards

Weight is one of the important indicators to measure the growth and development of spare chickens. The development of bones is closely related to the egg weight and egg shell strength of the hen in the future. In the management, the average body weight and skeletal development of the opening chickens can be achieved at the same time is an important sign of body maturity. Different chicken breeds have their own standard weight. When they are overweight, they have poor sexual performance. The development of bones is expressed in terms of length. The body weight is up to standard and the length is not up to standard, indicating that the body has excess fat, which directly affects the egg production and shell quality. The principle that should be mastered when adjusting body weight is to adjust energy based on the satisfaction of protein, and when the intake energy is high, the weight gain is accelerated. Therefore, in the breeding process, it is necessary to measure the body weight and length from time to time, and take appropriate feeding and management measures, in order to make their body weight and length in the opening can be at the same time.

Third, control the age of sexual maturity

Sexual maturity is related to the environment and heredity. Reasonable lighting is an important measure to control sexual maturity. After 12 weeks of age, the layer is sensitive to light stimulation, and light can promote sexual maturity. In the production, we should pay attention to the development of a scientific and reasonable lighting program, so that the chicken's body maturity and sexual maturity can be synchronized to ensure the full play of the potential for production. If the body weight is met, it should be extended by 1 hour per week from 18 weeks of age or 20 weeks of age until it is constant at 16 hours. If the 20-week-old body weight is still not up to the standard, the supplemental illumination time will be postponed one week later, and nutrition will be enhanced at this stage to promote the body weight.

Fourth, strengthen the scientific management of egg production period

1. Guarantee the most suitable temperature range. Production practice shows that 13-23°C is the most suitable temperature range for chickens to produce eggs. If the temperature is too high or too low, it will affect the chicken production rate and eggshell quality. Therefore, it is necessary to do the summer heatstroke cooling and the winter cold and warm work. .

2. The ventilation in the house is good. Ventilation and ventilation can play a role in sewage discharge and temperature and humidity adjustment, especially in large-scale intensive chicken farms. Ventilation and ventilation play an important role in excavating chicken egg production potential. According to the specific circumstances, natural ventilation and mechanical ventilation can be carried out.

3. Reasonable lighting plan. The principle of illumination during the production period is that the illumination time should be longer and not shorter, and the light intensity can not be weakened, so that the hens can start production at the right time and reach the peak of egg production, and give full play to their egg production potential.
4. Comprehensive health and epidemic prevention measures. Pay attention to maintaining the cleanliness and sanitation of the house and the environment. Wash the sink and feeding tools regularly and disinfect regularly to prevent the occurrence of diseases.

5. Reduce stress factors. Sudden changes in any environmental conditions can frighten the flock and cause stress, leading to poor appetite, reduced egg production, and soft shell eggs. In addition to taking targeted measures to reduce stress, it is necessary to formulate and strictly implement scientific broiler house management procedures, including lighting, ventilation, feeding, water supply, and feed replacement.

Fifth, strengthen rearing and management after peak production

The key part of the management after the peak period of egg production is to adopt restricted breeding to prevent the hens from being over-fat and affect the performance of laying performance, so as to ensure that the egg production in the middle and later stages is good. The specific method is to limit the feed when the egg production rate drops by 4 to 6 percent after 3-6 weeks after the egg production peak, and the trial consumption is combined with the production curve during the feed restriction process to prevent the egg production rate from being reduced due to the material reduction. Drop quickly.

Sixth, strict control of feed management

1. Avoid moldy feed and poor quality additives.

2. Feed the full price of ingredients according to the feeding standards of the chicken species to ensure that the nutrition is adequate and reasonable.

3. The adjustment and transition of the diet should be reasonable. The influence of factors such as temperature change during production and feeding at the stage requires timely adjustment of feed nutrient content.
