Farmers with farming experience will have such a farming experience: laying hens often produce a certain number of soft-shell eggs and thin-shell eggs, especially when laying hens enter the peak period of egg production, this phenomenon is more serious, thus reducing the economic benefits of farmers. The main reason for this phenomenon is that because the calcium content required by the laying hen does not meet the standard, how should we give the laying hen a scientific calcium supplement when using thepoultry layer cagesto raise chicken?

1. Calcium should be selected at the right time. Farmers can make calcium supplements before turning off the lights in the afternoon to night. It is best from 2 to 4 pm. It has been determined that most of the calcium absorbed by chickens in the morning is stored in the bones, and the calcium absorbed in the afternoon or evening is directly used for the formation of the eggshells of the day. And from 2 pm to 4 pm, it is the peak of feeding in the day of the chicken, and the appetite is the strongest. Therefore, you must choose the right time when you are feeding the chicken in the egg cage.

2. Calcium must choose a good calcium material. Eggshell powder is the best choice, followed by shell powder and bone powder. The eggshell powder has a uniform particle size, which is consistent with the feeding habits of the chicken, while the shell powder and bone powder vary in size, which affects the foraging effect. Other fine powdery calcium feeds are not easily used for supplement feeding.

3. Choosing the right supplemental feeding method is the most important. If it is free to eat, after 2 pm, let the chicken eat the feed in the trough first. When the chicken has a certain appetite half an hour, spread the calcium material to be evenly scattered in the trough; if it is timed Feeding, you can feed the calcium before feeding in the afternoon, and then feed the full price feed. Either way, you must ensure that all chickens can eat calcium at the same time, in order to achieve the full calcium.

4. Scientific calcium supplementation. The amount of calcium supplement must be proportional. Too much or too little is not conducive to laying eggs. The amount of calcium supplemented should be determined by the ratio of soft shell eggs to shell eggs. Generally, the soft shell and the thin shell egg basically disappear, and the chicken is not willing to eat calcium material. If the egg shell is not smooth, the protruding calcium point appears, indicating that the calcium is too much. It is usually advisable to supplement about 0.5kg per 100 chickens.

The above is what the farmers want to tell the farmers how to make scientific calcium supplements when laying chickens in laying hens.
