The restocking of young chickens must not be directly replaced with egg-laying chickens, nor can they be suddenly reloaded. If you are eager to complete the refueling at one time, the composition of calcium and crude protein will suddenly increase, especially if the protein is increased and the amount of drinking water increases. The body of the chicken will cause diarrhea due to poor digestion and absorption. Therefore, for the young chicken refueling, the feed calcium is generally about 0.8%, about 15.5% of crude protein; to egg-laying refueling, the best choice for the egg production rate of 2% -5% when the change into laying hens Material, calcium content of laying hens should be 3.4% - 3.5%, containing 18% crude protein. When refuelling, young chickens reared in the summer with natural lighting tend to start late, and they may start restocking at 18 weeks of age. If the chickens are reared using natural light after winter, they often start production earlier. Reloading at 17 weeks; generally for the 19-20 weeks old chicken feed for egg production, also known as the transition material, the calcium and protein components of the feed should be increased than the young chicken's feed, the general calcium ratio At 1%, crude protein was 16.5%. When reloading, the reloading process was gradually completed after about half a month, and it was not possible to reload suddenly.
