Summer Mastitis in Heifers: Observations on the Effect of Insect Attacks on the Teats of Heifers

Abstract

An estimation of the possible etiology behind summer mastitis in heifers includes an evaluation of the significance of various insects as hosts for the causal microorganism. Under Danish conditions, several species of insects may be considered disease-carriers, such as Simulium sp., Culicoides sp., tabanids and Hydrotaea irritans (Fall.) in particular. In contrast to the other insects mentioned, Hydrotaea irritans is not able to penetrate the skin by itself but depends on one of the species of insects able to carry out the necessary opening of the skin in order to be able to pick up a “blood meal” (cf. Hϕi Sϕensen 1979).
