The laying period of laying hens is the most important period in the whole growth process of laying hens. This period is divided into three sections. The nutrient levels of laying hens are different in each stage, so the farmers should also give the laying hens in these three stages. Feeding diets with different nutrient levels. This will ensure that the laying quality of laying hens will not decline. In the early stage of laying, that is, from the beginning of production to the peak of laying eggs, the laying rate of chickens is more than 80%. During this period, the content of nutrients such as protein and calcium in the diet should be The flock’s egg production rate is increased and added. In the middle of laying, that is, after a peak of egg production, the laying rate of chickens is between 65% and 80%. In the later stage of laying, that is, when the laying rate of the chickens is 65%. The content of nutrients such as protein, calcium and phosphorus in the chicken diet in the latter two stages should be reduced as the egg production rate decreases.
In the question of feeding time and frequency, the appetite of the laying hen should be maintained. After each feeding of the laying hen, the trough should be cleaned in time to prevent the feed from being stored in the trough for a long time, so that the hens have anorexia and picky eating habits.
To ensure that the chickens have sufficient water supply, if the laying hens are cut off for 24 hours, the egg production will drop by 30%. It takes about one month to recover. If the water is cut for 36 hours, the egg production will not be restored to the original level; For more than 36 hours, some chickens will stop laying eggs and start moulting. This will cause economic losses to the farmers, so the farmers must provide adequate clean drinking water to the laying hens.
Doing a good job of controlling the age of primiparity and adopting the mature mature period of fasting method has a good effect on delaying the primiparity of the bred chicken, improving its egg production performance and promoting high yield and stable yield of the chicken. Specific practices: starting from 5% of the flock’s egg production rate, fasting for 8 to 10 days (pay attention to normal water supply).
