"Metaphylaxis" in post-partum conditions in dairy cows with butaphosphone: a trial under South African conditions.

Current literature on the prevention of the "parturition syndrome" in dairy cows using butaphosphone is summarised. A South African trial is recorded in which 2 pre-partum injections of the drug caused a significant reduction in the number of cases of parturition syndrome, as well as a marked reduction in intercalving period in the treated portion of the herd. No difference in lactation yield or culling rate was seen. The financial implication of the reduction in intercalving period is discussed.
