A non-hormone-containing, antibiotic, lean, and non-toxic substance that not only effectively promotes the normal healthy growth of livestock, but also increases the individual's resistance to disease and has a two-way regulating function of "feeding active peptides. "Additives" was successfully developed by researchers from East China University of Science and Technology. The green additive is a feed polypeptide additive formed by deep-sea fish meal as a raw material, low-temperature enzymolysis and addition of various trace elements. The additive is a green additive, non-toxic, growth-promoting, disease-resistant, and non-polluting emissions; due to its low cost, it only needs 50 yuan per ton of common feed additive, which is 40% lower than the original target. 50% can increase the net weight of pigs and broilers and the laying rate of laying hens. This is a very scientific project with broad prospects for development.
