Uses of Hygromycin B : Hygromycin B , very safe de-worming drug, can effectively kill the roundworm of pigs, whipworm and chickens' roundworm, and have antibacterial effect. And it also can be used for chicken feed (the dosage of 8 (800 × 104U)-12 (1200 × 104U) g / t, Laying disabled, withdrawal period 3 days) and the following 4-month-old pig feed (the dosage of 10 -- 13g / t, withdrawal period of 15 days, to avoid eye contact with human skin).

When you are using this chemical, please be cautious about it as the following:
The Hygromycin B is very toxic by inhalation, in contact with skin and if swallowed. It may cause sensitization by inhalation and skin contact. It has risk of serious damage to the eyes and limited evidence of a carcinogenic effect.
