Heat stress in cattle causes millions of dollars of losses each year due to production losses, and death losses in extreme cases. A study was designed to determine severity of heat stress among four genotypes of cattle. One-hundred twenty-eight feedlot heifers of four different genotypes were observed throughout a typical summer. Respiration rates, panting scores, and surface temperatures were taken twice a day on 10 animals/genotype for several weeks during the summer. Twenty-four hour… CONTINUE READING
