In order to prolong the hen's laying time
In order to increase the egg production of laying hens, experts suggest that there are several key links in production management. “The criterion for measuring chicken egg production performance is mainly the hen's egg production, peak height and peak maintenance time.†Professor Song Zhansheng, animal husbandry expert at Northwest Agriculture and Forestry University believes that in the production of layer chicken, the general feed costs account for 60% to 70% of the total cost. Therefore, reducing feed consumption is an important way to improve the breeding efficiency of laying hens. Egg production period strengthens scientific management Production practice shows that 13 °C ~ 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's egg production rate and eggshell quality. Therefore, it is necessary to do a good job of preventing cold in winter. In addition, ventilation can play the role of sewage, regulate the temperature and humidity inside the house, especially in large-scale intensive chicken farms, ventilation and ventilation plays an important role in the excavation of chicken egg potential. According to the specific circumstances, natural ventilation and mechanical ventilation can be carried out. Restricted breeding at the peak of egg production The key link in the peak season of egg production is to implement restricted breeding to ensure the continuity of egg production in the middle and later stages. The specific method is to limit feeding when the egg production rate drops by 4% to 6% after 3 to 6 weeks after the peak of egg production, and the trial consumption is combined with the production curve in the feed restriction process to prevent the egg production rate due to material reduction. Fall too quickly. Consider the increase or decrease in feed intake based on weight changes. The specific determination of feed intake must also consider the effects of seasonal factors. When picking sick chickens in time, when feeding or observing chickens, chickens that are found to have poor mentality, white or purple crowns, and legs that cannot stand should be picked out in time to prevent them from dying in cages. Strictly grasp the quality of diet Avoid moldy feed and poor quality additives. Feed the full price of ingredients according to the feeding standards of the chicken species to ensure that the nutrition is sufficiently reasonable. The adjustment and transition of the diet should be reasonable. Affected by factors such as temperature changes and stage feeding in production, it is necessary to timely adjust the nutrient composition of the diet. During the phase of raising the chicks in the breeding period to the stage of growing chickens to the stage of laying eggs, the diets requiring different nutrient components are gradually transferred. All dietary composition adjustments must be carried out gradually and avoid sudden changes.
