Metabolic studies on daily and weekly feeding of ruminants given all-wheat diets. 3. The activities of enzymes in sheep tissues

Abstract

The activities of gluconeogenic, glycolytic and lipogenic enzymes have been measured in tissues from sheep given either 300 g of wheat each day or 2100 g wheat each week. The mean activities of gluconeogenic enzymes did not differ between the two feeding regimens; however, in sheep on the weekly feeding regimen, the activities of some gluconeogenic enzymes decreased after feeding and increased again at the end of the feeding cycle. On both feeding regimens the activities of glycolytic and lipogenic enzymes appeared to be increased by the all-wheat diet, although the activities of these enzymes did not differ between the regimens.
