Extract

Leptin is an important hormone for the control of food intake and body weight homeostasis in human and rodents. In ruminants, plasma leptin is positively related to body fatness and energy balance or feeding level (Chilliard et al., 2001) and linked to meat quality determinants such as marbling score (Minton et al., 1998). To our knowledge, no information is available on the effects of the nature of dietary forage on this parameter. The objective of the current work was to examine the effects of replacing maize silage with grass on plasma leptin as well as on the activities of five lipogenic enzymes in perirenal and inter-muscular adipose tissues (AT).
