(Averages of breed-tests conducted at the annual dairy shows of the British Dairy Farmers' Assoc., 1879-95, inclusive.) ENGLISH STANDARDS FOR ANNUAL YIELD OF MILK OF THE VARIOUS BREEDS. The standards proposed for the respective breeds by the British Dairy Farmers' Association for entry in the "Dairy Cattle Register" are as under: The standard for crosses of either of the above will be the mean of the standards for the pure breeds. No animal is admitted whose milk contains less than 12 per cent of solids at any test. (McConnell.) AVERAGE YIELDS AND COMPOSITION OF MILK OF DIFFERENT BREEDS. (Hucho.) AVERAGE PERCENTAGE COMPOSITION OF MILK FROM DIFFERENT BREEDS. (König.) The British Dairy Farmers' Association, which has conducted tests of dairy cows at their annual fair for the last fifteen years, has scored the dairy cows competing for premiums according to the following scale during late years: I point for each pound of milk; 20 points for each pound of fat; 4 points for each pound of solids not fat. I point for each ten days in milk after the first twenty days (limit 200 days). 10 points are deducted from the total score for each per cent. of fat below three per cent in the milk. The cows entered in the test are separated into four classes, according to the breed, each class being divided into two divisions, cows and heifers. The classes are Shorthorns, Jerseys, Guernseys, and cross-breeds. Other associations abroad or in this country have not generally followed any definite plan from year to year in awarding premiums to dairy cows at fairs, the awards having been given to cows producing most milk, or richest milk, or most butter-fat, or most solids, during the test, which may have lasted one to three days. At the Vermont State Fair, 1889, the following points were given: For each 20 days since calving, I point; for each 10 days of gestation, I point; for each 2 oz. of total solids in 24 hours' milk, I point; for each oz. of butter-fat in 24 hours' milk, 2 points; for each 2 oz. of salted butter from 24 hours' milk, I point. In the milking trials conducted by the Royal Agricultural Society of England, the size of the cows has been considered, the cows being, as a rule, separated into two classes, viz., over and under 1100 lbs. live weight. From the best information at hand at the present, the system of awards adopted by the British Dairy Farmers' Association, and given above, must be considered the most perfect and the most just to all concerned. Its main shortcomings lie, as it would seem, in its not considering the food eaten by each animal during the test, and in the fact that the test is made at the fair, and not at home under every-day conditions and in surroundings familiar to the animals. The former objection would be removed by taking into account the dry matter in the food eaten, as shown by chemical analysis. BUYING AND SELLING COWS BY TESTS OF THEIR MILK. (EMERY.) The money value of a cow may be estimated by multiplying the number of gallons of milk which the cow gives by 12, adding to or subtracting from this product one dollar for every one fourth per cent of fat in the milk above or below 3.5 per cent. Value = pounds of milk per day 8 X 124 (per cent fat-3.5). (See Bull. No. 113, N. C. Exp. Station.) |
