July 2026 in “Frontiers in Endocrinology” This study observed that beef cattle with certain prolactin receptor gene mutations, known as slick mutations, demonstrated improved post-weaning growth and temperature regulation in a hot, humid climate compared to other genotypes, suggesting genotype influences growth efficiency and heat tolerance.
November 2020 in “Journal of animal science/Journal of animal science ... and ASAS reference compendium” This study identified several genetic variants associated with cattle hair coat length, which may help breed more heat-tolerant animals by facilitating efficient heat loss.
