Comparative study of plasma leptin concentration
between ruminal and abomasal feeding in sheep

Leptin plays an important role in regulation of energy balance in mammals. This experiment was conducted to investigate the difference between ruminal and abomasal feeding of plasma leptin concentration in ruminants. Plasma leptin, insulin and glucose concentrations showed different trends by conversion from ruminal to abomasal feeding in samples collected from sheep every 2 days at just before morning feeding throughout the experiment, and these concentrations were not stable in abomasal feeding. Plasma insulin and glucose increased dramatically after feeding in abomasal feeding than ruminal feeding, while plasma leptin did not show any change after feeding. Changes in plasma leptin concentration could be due to changes of the digestive system and/or changes in plasma insulin and glucose concentrations with following change of digestive system.
