Bulletin 142, Dairying in Florida FIG. 19.-Creole's Lassie Sue No. 306835 milk and butterfat produced within a given length of time- must be authenticated by disinterested supervision. Such super- vision is usually delegated to the experiment station or agricul- tural college in the state in which the cow is owned. The Florida College of Agriculture is ready to act in that capacity for Florida owned purebred cows of any breed. The only Jersey cow bred and raised in Florida that has made the Register of Merit of the American Jersey Cattle Club is Creole's Lassie Sue No. 306835 (fig. 19). Her required test be- gan September 19, 1916 and closed September 18, 1917. In the 365 days she produced 7708.6 pounds, or 896.3 gallons, of milk end 374.32 pounds of butter fat, or 436.7 pounds of butter. Bran, velvet-bean meal, cottonseed meal, beet pulp, shorts, pea- nut meal, corn meal and silage were the feeds used during the test. The total cost of the feed for the year was $107. The value of the milk produced was, if figured at 50 cents a gallon, $448. Deducting the value of the feed leaves a balance over cost of feed of $341. Or, the feed cost of a gallon of milk was 12 cents. This cow is five years old.
