Growth promoters in humans
The maintenance and enhancement of body composition is an energy-dependent process and is impossible without an adequate supply of energy and protein. In certain circumstances, alteration of the normal pattern of protein deposition and metabolism may be considered necessary. Drugs have been used with some success in attaining this end in three distinct clinical areas. First, they are proving ef...

متن کاملAlternatives to Growth Promoters
In pig production, the terms "growth promoter", "performance enhancer", and "digestive enhancer" include a diverse range of products ranging from simple chemicals (copper salts) to chemically produced antibacterial compounds (carbadox) to antibiotics (tylosin, avilamycin, salinomycin, virginiamycin). Most of the antibiotic group are produced during a fermentation process by yeasts, moulds, and ...

متن کاملAntibiotic growth promoters.
Sir, I was dismayed to see that Phillips et al. were defending what nearly all microbiologists know are grave abuses of antibiotics— their continuous use in feed as growth promoters and the needless widespread use of broad spectrum agents (fluoroquinolones). This is despite their acknowledgement that ‘the more an antibiotic is used, the more likely are resistant populations to develop’ and that...
