The laying rate of laying hens is an important factor influencing the economic benefit of chicken farmers and is one of the important links in improving egg production. According to the chicken's physiological characteristics and nutritional needs to strengthen the breeding techniques, it is of great significance to improve the egg laying rate. There are mainly the following methods in feeding and management:
Section feeding
According to the age of laying hens and the level of laying eggs, the laying period of laying hens is divided into different stages. At the same time, adopting different management methods can increase the egg production rate of laying hens and achieve a multiplier effect. Generally take two or three stages.
The two-stage method is based on 50 weeks of age. Before that, the body of the chicken has not yet fully developed. At this time, it is a chicken egg production period. The protein content of the chicken feed should be 16%-17%. After 50-week-old chickens have completed their body development, egg production no longer increases but they begin to decline. Therefore, the need for protein is reduced, so the protein level must be controlled at 14%-15%.
The three-stage method is divided into three stages according to the age of chicken: 20-42-week-old, 43-week-62-week-old and 63-week-old. In these three stages, the protein content in feed is divided into 18%, 16%-17% and 15%-16%.
When feeding in batches, it takes one to two weeks for the feed to change as a transitional period. Do not change the feed abruptly. This will cause stress to the flock and affect egg production. This segmented feeding method can make the peak of egg production in the chicken appear earlier and increase quickly. The long duration of egg production has long duration, which reduces the cost of feed and increases the egg production of chickens.
Restricted feeding
Restricted feeding during the laying period of chickens can increase the utilization of feed, save feed, reduce feed costs, and can well control the weight of chickens, reduce the need for chicken maintenance, and increase the production needs of chickens. In the limited feeding of laying hens, many factors such as chicken breed, environment, temperature, season, etc. must be taken into consideration, and they cannot be generalized. It is generally believed that the amount of energy in the feed should be reduced by 8%-10%.
Adjusting feeding
Based on the feeding standards of layer chickens, the relative stability of the chicken diets is maintained. No matter what the circumstances, the formulation of the feed can not be changed greatly, and the raw materials and nutrient components can not be greatly changed. Fine-tuning is needed to make the chickens adaptable. The process, otherwise it will affect the chicken's feed intake, resulting in decreased egg production. Each adjustment must carefully observe the chicken's feeding conditions and egg production, so that timely detection, find out the reasons for timely adjustments. As long as we understand the physiological characteristics of chickens and its rules of egg production, strengthen feeding and management, and provide a good living environment, and carefully implement the operation of each link, we can increase the chicken egg production rate and achieve the desired results.
