The SLICK gene is a mutation in a prolactin receptor that causes animals to have shorter hair. In the 1980’s Florida dairy farmers and UF Animal Scientists found that breeding Holstein cows to Senepol semen resulted in some offspring with slick haircoats. The University of Florida dairy unit and animal science researchers have developed homozygous SLICK bulls for commercial use. Research is ongoing to determine the thermotolerance benefits of the SLICK gene.
