In the latest issue of the Professional Animal Scientist, the article entitled: “Characterization of a composite population of beef cattle in subtropical south Texas and the effect of genes for coat type and color on preweaning growth and influence of summer breeding on sex ratio” has been published. The theme of the work deals with the breeding of cattle over years of extreme drought, and is the result of nearly 10 years of performance data collection in Star cattle. Briefly, the article consists of four parts: 1) economic trends; 2) estimation of breed and heterosis; 3) effects of genes for slick and coat color, and 4) the influence of summer breeding on sex ratio. The most major results include the dramatic and positive effect of the slick gene on weaning weight and of summer breeding on producing 50% more bull than heifer calves.
