Abstract
in English, Swedish

The effect of acrosomal aberrations of the spermatozoa of Finnish Ayrshire bulls on the corrected non-return rate within 60 days of the first 500 inseminations was studied. The material consisted of sperm samples examined by the artificial insemination societies. All samples had been accepted for use in artificial insemination. One Giemsa-stained slide was studied for each of the 95 bulls concerned. Samples showing distinct acrosomal defects were studied by electron microscopy. Three different types of acrosomal aberration were found. One was obviously associated with subfertility in all 6 bulls in which it was detected.

I denna undersökning studerades sambandet mellan akrosomavvikelser hos tjurar och det korrigerade resultatet för ejomlöpningsprocenten inom 60 dagar för de första 500 insemineringarna. Tre akrosom-avvikelser konstaterades hos Ay-rasen. Materialet utgjordes av spermaprover som studerats av seminfbreningarna och samtliga prover hade godkänts för artificiell inseminering. Ett Giemsa färgat preparat studerades från var och en av de 95 tjurarna. De spermaprov som uppvisade tydliga akrosom-avvikelser undersöktes i elektronmikroskop.

En av dessa akrosom-avvikelser hade ett uppenbart samband med subfertilitet hos alla de 6 tjurar hos vilka awikelsen konstaterades.
