Effects of Wheat Germ Oil on Reproductive Efficiency in Repeat-Breeder Cows¹

Department of Dairy Science, Kansas State University, Manhattan

ABSTRACT

Clinically normal repeat-breeder cows that had failed to maintain pregnancy after three or more services were alternately assigned to the experimental or control group. The experimental cows received 2 oz of wheat germ oil on their feed once a week for six consecutive weeks. A significantly higher percentage of the 79 treated cows maintained pregnancy after the first post-treatment service than of the 88 untreated cows. The difference in post-treatment conception between treated and untreated cows that had three unsuccessful services before treatment was not significant; however, there was a highly significant difference in favor of the treated cows that had been bred four or more times before initiation of treatment.
