Veterinarians and Artificial Insemination BY C. A. V. BARKER * FfNHE ARTIFICIAL breeding of dairy cattle has developed rapidly in 1 Canada during the last five years. Artificial insemination units have been established in the main dairying areas of all the provinces and in most instances have proven to be successful, expanding in services from year to year. Some of the success of these breeding projects must be attributed to the fact that veterinarians have been placed in charge of the technical procedures involved in artificial insemination. The photograph accompanying -this article was taken at the recent -opening of Oxford County Holstein Unit at Woodstock, Ontario. The veterinarians in tle photograph are at present actively engaged in artificial insemination work. Dr. J. S. Johnson is veterinarian in charge of the Waterloo Holstein Unit and in addition is chiefly responsibIe for the collection and disposal of semen from the famous Holstein bull Montvic Rag Apple Sov.ereign. Dr. Johnson also conducts an extensive practice assisted by a graduate veterinarian. Drs. C. R. Reeds and R. Macdonald are former graduate assistants of Dr. Johnson, receiving practical tr'aning for a year with him. Dr. Reeds for the last two years has been supervising the York County Holstein Unit at Maple, Ontario. This unit has been one of the most successful units in tOntario, serving the breeders in that area and in addition supplying semen to veterinarians in surrounding districts. Dr. Macdonald has been in charge of the Woodstock Unit since its inception in May of this year. iFourteen bulls are in service at this centre, supply~ing semen for the whole of Oxford County. Semen from the top price bulls costs $100 per cow settled, lower priced bulls rating $50 and the average fee being $5.00. Present plans indicate that over 200 members will soon be enrolled, en- tailing the services of additional technicians. Dr. D. C. Reid is veterinarian in charge of the New Jersey State 'Breeders Unit at Clinton, N.J., U.S.A. Dr. Reid has three graduate veterin- ar,ians as assistants. This unit was the first co-operative unit established in the United States. Dr. Reid spoke brie'fly on various features of artificial -insemination at the opening of the Oxford County Unit. In add'ition to the units at Waterloo, Maple and Woodstock, a fourth -unit supervised by Dr. D. Wilson is located at Forfar in Leeds County. 'Several -units snaller than these four are in operation in Ontario under the guidance o'f lay technicians. -The value of artificial insemination to the dairy cattle breeder has been clearly Shown in the results achieved by the work of artificial units. These results have stimulated breeders outside the unit areas to look for -some form of artificial insemination service. Consequently veterin- arians are frequently requested to render services of this nature. Many veterinarians in spite of the fact that they have more work than ever to do, have readily accepted artificial insemination and gradually it is * O.ntatis veterinary CDllege, Outlpl. Ont.

The veterinarian is able to diagnose and treat more cases of infertility, in many instances prolonging the life of a cow that would other- wise have been slaughtered. In addition it is a procedure whereby the veterinarian may be assisting in the control of an infectious disease by performing the insemination properly, and the owner will be appreciative. Furthermore there should be some satisfaction from the improvement noted in the resulting offspring sired by semen from superior sires. The remuneration derived from artificial insemination work is by no means snmall. Most of the artificial units have an advantageous salary scale, pay mileage, and with some units permit sterility treatment fees. Possibly one reason for lack of interest in this work has been the inability on the part of the practitioner to obtain semen. This reason may be obviated by the fact that sufficient units have been established in most of the provinces to provide occasional semen samples. Agricultural institutions have also undertaken to provide semen to a limited extent for custom service and thus there should be available through either of these a supply of semen. If veterinarians take advantage of the opportunities provided by artificial insemination ,work they will soon find a large clientele waiting for their services, and no reason to believe that this phase of veterinary medicine has escaped into the hands of trained lay technicians.
