Egg calcium is best in the afternoon

Calcium is an indispensable dietary element for laying hens. If there is insufficient calcium in the diet, it will directly affect the egg production, shell thickness, egg fertilization rate, chick hatching rate, and serum calcium content. Therefore, calcium supplementation to calcium-deficient laying hens is not only extremely important, but also very careful. Calcium and calcium source calcium source feed selection, the best effect of seafood shell powder. The coarse shell powder is made by crushing large shells, and does not contain fine sand. The calcium content is generally 35% to 37%. It is a high-quality calcium source feed for laying hens. Calcium-producing hens lay more eggs in the morning, and half an hour after laying eggs, the next egg yolk is discharged from the ovary into the fallopian tube. Therefore, continuous egg-laying hens do not need calcium supplementation in the morning, and after 2 pm, as the egg shell deposition rate increases, the calcium requirement for chickens also increases. Therefore, in order to make laying hens produce more eggs and produce good eggs, the effect of feeding calcium hens on laying hens is best from 2 pm to 6 pm every day. Calcium supplementation The production of laying hens requires calcium supplementation, but it is not always better. For a layer of eggs, 4.4 grams of calcium is required for each egg. The calcium content in the diet is 3% to 3.5% to meet the production needs of the layer. If the calcium content in the diet exceeds 4%, adverse symptoms will occur: on the one hand, the palatability of the feed will be deteriorated and the feed intake of the chicken will be reduced; on the other hand, it will cause the accumulation of urate in the hens, leading to Indigestion causes diarrhea, and severe symptoms can cause gout. Calcium supplementation method Calcium source feeds can be placed separately, allowing any chicken to feed freely, or they can be mixed in feed.
