A Study of “Growth Stimulants” using the Baby Pig

Abstract
A study of several possible growth stimulants for baby pigs was made using 29 animals fed a purified diet. Of those compounds studied, sulfisoxazole (3,4-dimethy1-5-sulfanilamido-isoxazole) and surface activating agents either alone or in a mixture of 8, failed to stimulate the growth of baby pigs up to 5 weeks of age. When fed at a level of 90 mg. per kg. dry matter diet, arsanilic acid (p-amino-phenylarsonic acid) significantly increased the growth and feed consumption of baby pigs up to 5 weeks of age. The effect of the antibiotic concentrate, Number 802, on the final weight of baby pigs up to 8 weeks of age, was observed to be highly significant. Copyright © . .
