The impregnation of mares cannot be exi>ected unless we have spermatozoa of a high vitality with whicli to do the work. The need of this has been shown in ner.rly every chapter of this work. Xor should we begin our work of breeding marcs by the capsule method, until we know the srallidii cr jack that is to lurnish the spermatozoa has been tested and lound in breeding condition. Oac has no right to expect aniare to produce a foal just because a capsule filled with some Huul of unknown quality has been inserted into her uterus. A stallion that is not a breeder by natural service, will not prove a breeder by capsule service.. Figure 36.—The Carlson semen extractor. 81. yhere Semen is Deposited. So far as the stallion is concerned, the only advantage the capsule otTers, is in the fact that every service is a complete service, while the stallion makes only about 60 per cent, of complete services. In the case of 1196 mares bred by natural service. 19 ditTerent stallions being used and the mares examined imniediatclv after the service 715 were found with no semen whatever in the vaginal cavity", while in the case of 481 of them the semen, or a part at lea^t. was de- posited in the vagina. Here we have an average basis upon which to work Some stallions make more complete services than others. Yet if we take all stallions into consideration, we will have only about 60 per cent, of complete services. Stallions. Please
