| Outline of Final Research Achievements |
Ghrelin, a growth hormone secretagogue, may enhance milk production in lactating cows. We have investigated which nutrients could affect ghrelin secretion, then we found that some fatty acids in the diets increase plasma ghrelin concentraion in cows. However, which fatty acid can stimulate ghrelin secretion had not been cleared. In the present study, we examined the effects of feeding some fatty acids on plasma ghrein concentration and we found that ghrelin secretion is stimulated by medium-chain fatty acids, such as C8:0. In another examination, we investigated the effect of duodenal infusion of individual fatty acids on ghrein secretion, but there was not response to any fatty acids.
