Bacitracin zinc is highly effective against Gram-positive bacteria and also exhibits efficacy against some Gram-negative bacteria, such as spirochetes and actinomycetes. Additionally, it promotes the growth of livestock and poultry. Specific usage recommendations include:
For pig feed under 4 months old: Dosage ranges from 4 (16.8×104 U) to 40 (168×104 U) g/t.
For chicken feed under 16 weeks old: Dosage is between 4 and 20 g/t.
For cattle feed under 6 months old: Dosage ranges from 10 to 100 g/t.
For cattle feed over 6 months old: Dosage is between 4 and 40 g/t.
Bacitracin zinc is primarily added to feed as an animal growth promoter. Its activity is enhanced in the presence of zinc, cadmium, and mercury salts. Therefore, the zinc salt and manganese salt of Bacitracin zinc are commonly used as feed additives. Growth promoters, such as Bacitracin zinc, are non-nutritional additives that stimulate livestock and poultry growth, increase weight gain rates and feed utilization, and improve overall health.
