The Effect of Aureomycin on Growth and Reproduction in Swine1

Abstract

Growth and reproduction studies were conducted on successive generations of swine fed levels of 10.0, 50.0, and 100.0 mg. of aureomycin per lb. of feed. The feeding of aureomycin at high levels produced no adverse effects in numbers of pigs born per litter, birth weights, or weaning weights. Evidence is presented which shows that a significant difference between treatments in average daily gain was obtained for the period from weaning to an average weight of 220 lb., the 50.0 mg. level supporting the most rapid gains in each generation.

Apparently neither the feeding of aureomycin continuously during the growth and reproduction periods nor the use of high levels of aureomycin had a deleterious effect on growth or reproduction.
