In cage chickens, chicken soft shell eggs and thin shell eggs often appear. After these two types of eggs appear, the egg production rate is affected. Preventive measures are mainly calcium supplements. There are many sources of calcium, which are contained in various animal and plant feeds. The contents are not the same and there are differences. If calcium is used alone, eggshell powder and shell powder are the best, followed by bone meal and stone powder. The advantage of eggshell powder is that the particle size is suitable. The chicken likes to feed, the absorption and conversion rate is fast, and the effect is good. However, when feeding, it is also necessary to pay attention to the feeding time (using absorption and transformation characteristics), generally in the afternoon 2-4 The clock is the best, because the chicken is the peak of egg production in the afternoon and the peak of the food intake in the day. The amount of calcium is directly used to form the eggshell at the peak of the day. Therefore, the timing of timely calcium supplementation is very important. . The amount of calcium, according to their respective species, weight and egg production principle, usually per 100 chickens, each time calcium supplement 0.5 kg is appropriate. After calcium, how to identify the right amount of calcium? First, soft shell eggs and shell eggs disappeared. The second is that the surface of the egg produced is rough, with raised calcium spots, indicating excessive calcium supplementation. Third, the surface of the output egg is smooth, has a certain hardness, and proves suitable. Notice that for chickens to lay eggs normally, it is necessary to ensure that chickens often eat full-priced feed, no calcium, and normal egg production.
