Show CHOICE OF DAIRY SIRE IMPORTANT Greater Need for Using Bull of Tried Ability. Selection of tlie dairy-herd sire Is perhaps tlie must important factor to he considered in tlie development of a high-producing, economical dairy herd, says C. A. Smith, extension dairyman at the Colorado Agricultural Agricul-tural college. Cow testing association records so far taliulated throughout the United States show, he sa.s. thai about one- j third oi the pure bred sires are low- ering the production of their daugh- j ters in comparison will) the production of the dams of I hose daughters; about one-third are raising tlie production slightly; but the great increases are coming from only the remaining third of the sires in use. Tlie higher the production of the herd, the more dillicull it is to raise production through the sire, and the greater the need for using a hull of proved ability, it is pointed out. "Economical production of milk is an important factor in profitable dairying," Mr. Smith emphasizes, "and cow testing association records are showing the way to such economical production. Continued practice of close selection, coupled with better feeding and management, will raise the average production of oui dairy cows with a corresponding increase in the economy of that production. But still greater improvement may be made by paying close attention to the quality of the herd sire." |
