1. The effect of undernutrition on the levels of five enzyme activities has been observed in liver biopsy specimens taken from Suffolk-cross ewes in late pregnancy.
2. There was no significant effect on the levels of three important NADPH2-generating enzymes (i.e. glucose-6-phosphate, 6-phosphogluconate and tsocitrate dehydrogenases) when comparisons were made between groups of animals at the same stage of pregnancy. However, the proportion of very low 6-phosphogluconate dehydrogenase levels assayed in livers of the undernourished ewes was significantly increased as parturition approached.
