Electronic Theses and Dissertations
It is important in dairy cattle management to maintain steady and continuous growth of heifers and thereby secure properly developed cows which will give the production that is expected of them when they are brought into the milking herd. In general, heifer calves during the first twelve months of their growing period are carefully managed as to feed, housing and care to promote normal growth.

Both artificial insemination and ova transfer require the insertion of foreign bodies or instruments into the uterus. When such instruments enter this organ, there is always the possibility of introducing various kinds of bacteria. Very little information is available regarding the pathogenicity of these bacteria in the bovine uterus. The possibility of abortion due to such pathogenic …
