The Effect of a Combination of Penicillin and Streptomycin upon the Livability and Bacterial Content of Bovine Semen

Abstract

The use of a combination of penicillin and streptomycin in levels ranging from 100 to 1,000 units of each per ml. of diluted semen did not affect significantly the livability of bull spermatozoa during a 20-day storage period. The use of a combination of penicillin and streptomycin effectively controlled bacterial growth in diluted bull semen. © 1949, American Dairy Science Association. All rights reserved.
