Show THE jV ! PURE-BRED DAIRY ! SIRES ARE BEST (I'rfparfrt by ttlf C'nitefl Slates Depart ment ' o Agriculture.) I Unl.v 2,"i per cent of me' bulls :it tlie i lii'iid if dairy herds In the United Stittes are pure bred, jui ilniiisands ; nf pure-bred dulry bull calves are! slaughtered for veal every year be- j cause there is no demand for them as breeders. Undoubtedly some of these calves are Inferior and ought to be . slaughtered, says W. E. Wintermeyer, dairy husbandman of the United j Stiitea Department of Agriculture, hut tnnst of them are far superior to the p-;'i and scrub sires that are nmv being used in ninny dairy herds. Many dairymen with small and medium-size herds, which often contain poor cows, say they cannot afford to own a pure-bred dairy bull because; 'of the high original cost. In reality, says Mr. Wintermeyer, these men can least afford to own an inferior hull. In a new publication Just Issued by the bureau of dairy industry, as Leaf let No. 1G-L, "Pure-Bred Dairy Sires," Mr.. Wintermeyer quotes figures oli-tained oli-tained from the records of dairy-herd-improvement associations in all parts I of the United States that show how rapidly a good dairy sire can Increase the production of a herd of average cows. Cows lu these herds having an average yearly production of 4.fi!-i5 pounds of milk and 170 pounds nf but-terfat but-terfat a year and mated to pure-bred sires, produced daughters that averaged aver-aged 7,007 pounds or mill mul i',00 pounds of butterfat, n gain In one generation gen-eration of 2,1)12 pounds of milk and 121 pounds of hutterfitt per cow. This increase In butterfat production, produc-tion, at 50 cents a pound, is worth about SCO. Allowing about 23 per cent for the extra feed required for t lie higher production, the value of the net gain per daughter due to the purebred pure-bred site would be about S45. A purebred pure-bred bull would need to sire only a few such daughters to pay for himself, him-self, and the yearly Income would be Increased by an amount equal to $45 multiplied by the number of his producing pro-ducing daughters.
