Extending the production period of hens can effectively improve the positive benefits of the breeding farm. Let’s talk about how to extend the production period of hens in terms of feeding management.
Restricted feeding during peak egg production
The key part of peak egg production management is to implement restricted feeding to ensure good egg production in the middle and late stages. The specific method is to limit feeding 3 to 6 weeks after the egg production peak, when the egg production rate drops by 4% to 6%. During the feeding restriction process, the egg production curve is combined with tentative feed reduction to prevent the egg production rate caused by the reduction. Decline too quickly. Consider the increase or decrease of feed intake according to the weight change. The specific determination of feed intake must also consider the influence of factors such as seasons. Select sick and weak chickens in time. When feeding or observing the flock, any chickens found to be in poor spirits, white or purple crowns, and unable to stand on their legs should be picked out in time to prevent death in the cage.
Strictly control the quality of feed
Avoid moldy feed and poor-quality additives. According to the breeding standards of chicken breeds, they are fed full-price compound materials to ensure adequate and reasonable nutrition. The adjustment and transition of diet should be reasonable. During production, it is necessary to adjust the nutrient composition of the diet in a timely manner due to factors such as temperature changes and stage feeding. The transition from the chick stage to the brooding stage to the laying period in the stage feeding requires a gradual transition of diets with different nutrients. All adjustments to dietary ingredients must be carried out gradually, without sudden changes.
Strengthen scientific management during the laying period
Production practice shows that 13℃～23℃ is the most suitable temperature range for chicken laying. Excessive or too low temperature will affect the egg production rate and eggshell quality of chickens. Therefore, we must do a good job of cooling in summer and protecting against cold in winter. . In addition, ventilation can play a role in draining sewage and regulating the temperature and humidity in the house. Especially in large-scale intensive chicken farms, ventilation and ventilation play an important role in the development of chicken egg production potential. Natural ventilation and mechanical ventilation can be carried out according to specific conditions.
