xii Twenty-fourth Annual Report of the spectors’ samples were analyzed, both chemically and micro- · scopically, 135 manufacturers’ and dealers’ samples for registration purposes, and 34 consumers’ samples, making a total of over 700. Besides these, a large number of purity examinations were made for consumers. The Division has been interested in the adoption of a list of definitions of standard feeding materials. Such a list of definitions has been adopted by the Association of Feed Control Officials of the United States, and has been published to the trade. Division of Animal Hasbancliy. During the year, this Division has continued the experiments relative to the_ growing and fattening of hogs on diierent forage crops, especially young rye, clover, oats and succotash. This Division equipped a small plant for the prepara- tion and distribution of hog cholera serum during the early months of the year. The first serum was on the market in February, and at the close of the year, 13,430 doses had been put out. Members of this Division have vaccinated 146 herds, including 5,129 animals, of which 4,707 animals sur- vived, showing a mortality of 8.2 per cent. The serum alone · treatment was used in 93 herds, including 2,802 animals, of which 316 died, or mortality of 11.2 per cent Fifty-two herds were treated by the serum simultaneous method, in- cluding 2,327 animals, of which 110 died, or a mortality of 4.7 per cent. A With the above output of serum, we were in no way able to supply the great demand for it by the farmers of the State. ` Divisionpf Agrrononiy.
