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 .ltoreq. 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 secundinarum and/or endometritis was significantly higher in the > 9% fat group than in the .ltoreq. 9% fat group. Unobserved oestrus and ovarian cysts occurred with equal frequency in both groups.
