What varieties of growth-promoting pharmaceutical feed additives are there?
At present, domestically common feed additives can be roughly divided by function into nutritional feed additives, general feed additives, and pharmaceutical feed additives. This year, however, the state requires feed production enterprises to stop producing commercial feed containing growth-promoting pharmaceutical feed additives. That is, feed additives that individually have or simultaneously have effects such as inhibiting bacteria and preventing disease, deworming, promoting the utilization of feed nutrients, and promoting animal growth and production. So what varieties of growth-promoting pharmaceutical feed additives are there?

The above are the varieties of growth-promoting pharmaceutical feed additives, but starting from January 1, 2020, the product quality standards for all growth-promoting pharmaceutical feed additives except traditional Chinese medicine were abolished, veterinary drug production enterprises stopped production and imported veterinary drug agents stopped importing the relevant veterinary drug products, and the corresponding veterinary drug product approval numbers and imported veterinary drug registration certificates were cancelled at the same time. Relevant veterinary drug products already produced and imported before this may be circulated and used until the end of 2020.
