Does Slick Hair Beat the Heat?
Dairy cattle with high heat tolerance (Bos indicus) generally produce less milk than cattle from temperate climes (Bos taurus). Researchers at University of Puerto Rico at Mayaguez studied a union of the two types, the Puerto Rican Holstein, which features a short, slick coat of hair. They determined that the breed does tolerate heat better than its normal-haired Holstein counterpart. Countries with hot climates could take advantage of this discovery to potentially increase their food production and help reduce hunger.
