Various organs of chicks did not develop improved, and they with a smaller amount of water, the greater the number of its toxic side effects. ② Application of inadequate treatment: Nutritional additives selected category, probiotics class as opening drugs,long-term use for chicken is good, no need requires treatment. For antibiotics must require full course of treatment, usually in 3 to 5 days. ③ Blindly use some drugs: Some farmers on new drugs or new varieties have sided preferences, such as the use of florfenicol oral chicks opening drugs.
