Studies on the use of feed additives has occupied much attention at this research center. Addition of 60 ppm copper (Cu) has been shown to improve growth rate of turkeys up to 8 weeks of age, while 120 ppm Cu depressed growth at this age, presumably due to inhibition of the utilization of sulfur amino acids. Our previous study (POULTRY 82-2) has also shown that Terramycin at 80 g per ton improved rate of gain up to 12 weeks of age. The objective of the current study was to investigate the effects of a combination of Neomycin and Terramycin (Neo-Terramycin) and copper on the growth of turkeys.
