The problem of calcium deficiency in laying hens is not unfamiliar to laying hens farmers. Why calcium? How to make it up? When will it be made up? What materials are used? This has a scientific basis, improper operation can not achieve the best calcium effect. Today, I'd like to tell you some tips about calcium supplement for laying hens.

Why do layers need calcium?

It's a sacred thing to have a baby. If you can't get nutrition for layers, it's over. If you can't get nutrition for layers, your resistance will decline. During the laying period, there will be a decline in egg production rate, soft shell eggs, SHELLLESS eggs, and eggshell thinning. The impact is very direct. It directly affects the income.

How to more efficient go filling calcium?

1. First of all, how to choose calcium supplement products? In terms of characteristics, calcium can be divided into two kinds: inorganic calcium and organic calcium.

Inorganic calcium is the calcium element combined with inorganic substances. Inorganic calcium mainly includes stone powder, light calcium carbonate, calcium phosphate and so on. The advantage of inorganic calcium is that it has high calcium content. One disadvantage of inorganic calcium is that it needs the participation of gastric acid and low absorption rate;

Organic calcium is the element combined with organic matter, mainly including calcium formate, calcium lactate and so on. Its advantage is that animals absorb it better, because it does not need the participation of gastric acid in the dissolution process. In particular, Calcium propionate has more vitality (calcium formate) and more than 30.5 small molecular organic calcium, which is easy to be absorbed and utilized.

2. Calcium time? This is the key point. The best time for the absorption rate of laying hens is in the afternoon (12:00-20:00). Why? Because the time of eggshell formation is at night, the calcium fed in the afternoon will be absorbed by the uterus at the first time when it enters the body, and the calcium directly acts on the eggshell.

3. The wonderful use of vitamin C. Vitamin C has a great effect on laying hens. It can increase the activity of thyroid gland, indirectly promote the absorption of calcium, and improve the hardness and quality of eggshell. The dosage of vitamin C 25mg / kg is enough.

4. In addition to the above-mentioned vitamins as a medium to affect the role of calcium absorption, the appropriate combination of phosphorus will also increase the absorption rate of calcium. Generally, 1.5 to 1 is a good ratio. If you are not satisfied with this, add vitamin D3, but the above strategy is enough. No, it's OK.

The above is the process of laying hens calcium need to pay attention to a few tips, but calcium is not easy to be excessive, calcium material ratio control within 5%.
