Laying hens often produce thin shell eggs during the rearing process, which has a greater impact on feeding efficiency. Why do laying hens produce thin shell eggs and what measures should be taken to solve them? First, the main reasons for producing thin shell eggs in laying hens (1) The content of calcium in chicken feed is insufficient. In general, laying hens consume 3-4 grams of calcium per day. Below this standard, chickens will produce shell eggs. (2) The content of vitamin D in the feed is insufficient, especially vitamin D, insufficient. Vitamin D promotes the absorption of calcium and phosphorus in chicken metabolism. If calcium is not absorbed well and blood calcium is insufficient, chicken will produce thin shell eggs. (3) The imbalance of calcium and phosphorus in feed. The normal ratio of calcium and phosphorus in the chicken feed should be 2:1 or 3:2. If the proportion of phosphorus is too high, it will prevent or reduce the absorption of phosphorus. (4) The house temperature is too high. The temperature is high, the feed intake of chickens is reduced, calcium intake is insufficient, and it is easy for the chickens to produce thin finished eggs. (5) In the hot season, the chicken house should be cooled, the temperature in the house should be maintained at 18-23 degrees, and the energy and protein levels in the feed and the mineral content should be increased so that even if the feed intake decreases, normal nutrition can be maintained. need. (6) Strengthen feeding and management, keep the house quiet, eliminate noise, and reduce the occurrence of stress reactions.
