Abstract

The objective of this work was to study the effect of mild fat infiltration in the liver on the reproductive performance of Finnish Ayrshire cows. Eighty-five multiparous and 17 primiparous cows were investigated. The mean percentage of fat in the liver at 1 week after parturition was 3.9 ± 0.5. Cows with ≤ 9 % fat in the liver at 1 week after calving conceived slightly earlier than those with > 9% (87.1 ± 2.7 and 102.2 ± 15.0 days post partum, respectively). The difference was not statistically significant. The incidence rate of retentio secundina-rum and/or endometritis was significantly higher in the > 9 % fat group than in the ≤ 9 % fat group. Unobserved oestrus and ovarian cysts occurred with equal frequency in both groups.

Sammendrag

Syftet med detta arbete var att studera effekten av en mild fettinfiltrering i levern på reproduktions-beteendet hos finska Ayrshire kor. Åttiofem multipara och 17 primipara kor undersøktes. Medelvärdet i procent för fett i levern en vecka efter kalvningen var 3.9 ± 0.5. Kor med ≤ 9 % fett i levern en vecka efter kalvningen blev dräktiga något tidigare än kor med > 9 % fett i levern (87.1 ± 2.7 respektive 102.2 ± 15,0 dagar post partum). Skillnaden var inte statistisk signifikant. Fall av kvarbliven efterhörd och/eller endometrit förekom signifikativt oftare i gruppen med > 9 % fett än i gruppen med ≤ 9 % fett i levern. Osynlig estrus och cystor i ovarierna förekom lika ofta i både grupperna.
