The opening period is the most burdensome period of the hen's life. During this period, the feed intake of chickens gradually increases from 75 to 80 grams per day to about 110 grams, but it is still possible that the nutrients cannot meet the body's needs. To make it smoothly. Timely chicken feed transition to the pre-production stage of layer, feed, pre-production period of feed containing protein 19%, calcium 2%, the content of multi-dimensional feed in young chicken is about 2 times. Fill the shells, sand or limestone pellets until the chicken production rate reaches 10% and then feed the layered chickens again. During this period, the nutrient concentration of the layered eggs is basically the same as the pre-production material, and the calcium content should be increased to 3.5%. Metabolism energy can also be gradually increased as needed. During the peak period of egg production, the negative balance of nutrients that may occur during the peak season may affect the production. The initial egg production should be given from the age of 110-120 days, and the egg production should be started when the age of 125-130 days (or the egg production rate reaches 5%). Peak feed. If the maternity period is in the summer, energy and amino acid levels may be increased as appropriate. In addition, the addition of oils and fats to the feed can reduce the dust formed by the feed and also increase the palatability.
