The main source of nutrition for chickens in automatic layer cages is feed. Some feeds are nutritionally balanced to raise healthy chickens. The lack of calcium in some feeds will reduce the egg production of chickens.Therefore, it is necessary to reasonably control the time and method of calcium supplementation.
Scientific supplementary feeding quantity. The amount of calcium supplements depends on the ratio of soft-shelled eggs to thin-shelled eggs. Generally, soft-shelled and thin-shelled eggs have basically disappeared, and chickens are not willing to peck on calcium feed. If the eggshell is not smooth and there are protruding calcium spots, it means that calcium is supplemented too much. It is usually appropriate to feed every 100 chickens with a supplement of about 0.5 kg each time.
Choose an appropriate supplementary feeding time. From the afternoon to the night before the lights are turned off. The best is from 2 pm to 4 pm. According to measurements, most of the calcium absorbed by chickens in the morning is stored in the bones. The calcium absorbed in the afternoon or evening is directly used for the formation of eggshells that day. Moreover, 2 to 4 in the afternoon is the peak of the chicken's food intake during the day, with the strongest appetite and the fastest and most eating.
The correct method of calcium supplementation. If it is free to eat, you can let the chickens finish the feed in the trough after 2 o'clock in the afternoon. When the chickens have a certain appetite every half an hour, evenly spread the calcium feed to be supplemented in the trough. If it is fed regularly, calcium can be fed first before feeding in the afternoon, and then full feed. No matter which method is adopted, it is necessary to ensure that all chickens can eat calcium at the same time, so as to achieve the purpose of adequate calcium supplementation.
The above is the method summarized by modern chicken cage manufacturers. I hope that the above experience can help the farmers to supplement the nutrition for the chickens, so that the chickens can grow better and produce more eggs.
