title: Effect of heat stress on adipokines and some blood metabolites in goats from Jordan.
abstract: To date and to the best of our knowledge, there have been no available data on the interaction between heat stress (HS) and secretion of adipokines and some blood metabolites in Baladi goats from Jordan. Therefore, this study aimed at evaluating the changes in leptin, adiponectin, non-ester fatty acid (NEFA) and beta-hydroxybutyrate (BHB) concentrations in Baladi goats under HS conditions in Jordan. Six goats were exposed to direct solar radiation versus six goats exposed to shade regimen. Blood samples were collected and serum concentrations of leptin, adiponectin, NEFA and BHB were measured. Ambient temperature, relative humidity (RH) and body weight (BW) were recorded. Results indicated that leptin and adiponectin concentrations were significantly increased under HS. The concentration of NEFA was significantly increased under HS at the 7th and 14th days of the experiment, while mean total concentration of NEFA was not significantly affected by HS. Neither weekly nor mean total concentrations of BHB were significantly affected by HS during the experimental period. In conclusion, HS is associated with changes in leptin and adiponectin concentrations in Baladi goats. Heat-stressed goats were able to keep their blood NEFA and BHB concentrations similar to those of thermo-neutral goats.
