Research > Cattle Reproductive Physiology

Summary

The Cattle Reproductive Physiology project is currently undergoing a change in leadership.  Dr. Ron Randel, who successfully led the Reproductive Physiology project for over 40 years, retired in 2019.  We are excited to welcome Dr. George Perry who will take over this project in the fall of 2020.

Brahman Temperament and Effect on Reproduction

Late sexual maturity of Brahman cattle requires them to be 6 to 12 months older to reach puberty than are Bos taurus breeds. The selection has resulted in the identification of Brahman females capable of calving at 2 years of age. Stress during pregnancy is being studied using transportation as a stressor. The epigenetic influences are being studied relative to health, growth, temperament, and reproduction in Brahman cattle.

The temperament of beef cattle is heritable and alters animal productivity. Interactions between temperament and immune function are being studied. Evaluation of how temperament influences metabolism, endocrine function, and subsequent productivity is being done.
