effect of monensin supplementation of dried grass or barley diets on aspects of propionate metabolism, insulin secretion and lipogenesis in the sheep

The effects of 33 mg kg −1 monensin supplementation (+M) of barley (HC) or dried grass (HF) diets on aspects of propionate metabolism, insulin secretion, rumen vitamin B12 synthesis and lipogenesis in sheep were investigated. Monensin had no significant effect on the estimated metabolisable energy intake, or the liveweight gain, but increased the proportion of propionate in rumen volatile fatty acids (VFA), P
