Response of Pigs to Feeding of Vitamin B 12,Streptomycin and Sulfathalidine. ∗

Abstract

Summary

Increased growth of pigs fed for 17 weeks after weaning was obtained as the result of the addition of vit. B₁₂, streptomycin and B₁₂ or 0.5% sulfathalidine to a basal diet consisting of ground yellow corn, soybean oil meal, methionine, minerals and vitamins. Approximately the same growth was obtained by the feeding of the sulfathalidine, and the combination of B₁₂ and streptomycin, the growth in both instances being greater than that obtained with the pigs with the addition of B₁₂ alone. The increased growth obtained by all of the additions to the diet was sustained over the entire experimental period of 17 weeks.

Note: Since this paper was submitted for publication, Heidebrecht et al. (Okla. Agr. Exp. Sta. Miscell. Pub. No. MP22, June 1951) have reported increased growth and improvement of the general appearance of pigs fed sulfathalidine as well as certain antibiotics.
