How to properly supplement calcium in layer cages

Calcium is an indispensable feed in the daily production of laying hens, so how to use layer cages to properly supplement calcium? We all know that if the calcium in the feed is insufficient, it will directly affect egg production, egg shell thickness, and The fertilization rate of eggs, the rate of chicks emergence, and the calcium content of serum. So proper calcium supplementation is very important.


  1. Selection of calcium source feed


For the choice of calcium source feed, sea shell powder has the best effect. Coarse shell powder is crushed from large shells into particles with a diameter of 8 mesh to 12 mesh. It does not contain fine sand. The calcium content is generally 35% to 37%. It is a high-quality calcium source feed for laying hens.


  1. Calcium supplement time

When the hens lay continuously in the morning, the next egg yolk is discharged from the ovary into the fallopian tube half an hour after laying. Therefore, the hens do not need calcium supplementation in the morning. After 14 o'clock in the afternoon, as the eggshell deposition rate increases, the amount of calcium intake by the chickens also increases. Therefore, in order to make laying hens produce more eggs and lay well, it is best to feed the laying hens with calcium feed from 12:00 to 18:00 every day.



  1. The amount of calcium supplement

Laying hen production requires calcium supplementation, but not as much as possible. Generally, each egg lay requires 4.4 grams of calcium, and the calcium content in the diet is 3.0% to 3.5% to meet the production needs of the layer. If the calcium content in the diet exceeds 4.0%, adverse symptoms will occur: on the one hand, the palatability of the feed will be worse, and the feed intake of the flock will be reduced; on the other hand, it will cause the accumulation of urate in the laying hens and cause indigestion. And cause diarrhea, and severe gout symptoms may occur. Therefore, calcium supplementation in laying hens must be timely and appropriate.


  1. Calcium supplement method and effect

The calcium source feed can be placed alone, allowing the chickens to eat freely, or it can be mixed in the feed and fed. According to the experiment, the calcium source feed has a good effect on improving the egg production, the fertilization rate of the eggs, the hatching rate of the chicks, the serum calcium content and the thickness of the eggshell.


Automatic poultry chicken equipment manufacturers share the methods for reasonable calcium supplementation for laying hens. Farmers can supplement calcium for chickens according to the above methods, so that chickens can grow better and create more economic benefits for farmers.
