In the production process of chickens, some chicken farmers only know that chicken feeding bone powder can promote development, promote eggshell formation, and prevent soft eggs.
However, if the bone meal is too much, the feed diet contains more than 2.5% calcium (except for laying hens), high calcium and low phosphorus urine will occur in chicks and broiler chickens, and even nephritis, gout, urinary stones, and some Loss of appetite and death can occur. To this end, please pay attention to chicken farmers, chicken feed bone powder should be appropriate, not as much as possible. In general, the feed of the chicks should contain 2% calcium, the chickens should be 2.5%, and the laying hens should be 3.5%. Laying hens can increase or decrease the amount of bone meal according to the increase or decrease of egg production, but the maximum can not exceed 4%.
