(I) The phased rearing can not be neglected. The laying period of the commercial laying hens is divided into three stages, and each stage is fed with diets with different nutritional levels to meet their egg production needs. During the early period of laying, from the beginning of production to the peak of egg production, the egg production rate is more than 80%. During this period, the nutrient content of protein, calcium, etc. in the diet should increase with the increase of the egg production rate of the chicken; mid-production period, ie During the period after the egg production peak, the egg production rate is between 65% and 80%; at the later stage of laying, the egg production rate is less than 65%. The content of protein, calcium, phosphorus in the latter two stages of the diet decreased as the egg production rate of the flock decreased. (B) to control the initial age of the birth of a mature mature fasting method, to delay the initial age of broiler chickens, improve egg production performance, so that the high and stable production of chickens have a good effect. The specific approach is: starting from the chicken egg production rate of 5%, fasting for 8 to 10 days. (C) scientific feeding time and frequency In order to maintain a strong appetite of the chickens, there must be a certain time every day to set a slot, so as not to feed long-term storage in the chute, so that the chickens produce anorexia and picky eaters bad habits. (d) drinking water should be timely to stop the birds for 24 hours, reduce the egg production by 30%, take 25 to 30 days to return to normal; the chickens lose water for 36 hours, egg production can not be restored to its original level, cut off more than 36 hours Some chickens will stop laying eggs, resulting in moulting. Therefore, adequate drinking water must be supplied in a timely manner. (5) Feeding some health sand in appropriate amounts Both breeders and commercial laying hens must regularly feed gravel, especially for raising chickens in cages. The size of the gravel should be moderate, preferably 4 to 5 mm in diameter. The method of feeding is: the flat chicken can be placed in a sand trough, and the cage chicken can be mixed in the feed at a ratio of 0.5%.
