Abstract :
[en] To examine the relationship of insulin and glucose, broiler embryos were subjected to acute or prolonged hypoglycemia during the late embryonic phase by, respectively, injecting once (at embryonic day [ED] 16 or 17) or on 3 consecutive days (ED 16, 17, and 18) with tolbutamide (80?g/g embryo weight), a substance that stimulates insulin secretion from the pancreas. After 1 tolbutamide injection, a prolonged (32h) decrease of plasma glucose and a profound acute increase in plasma insulin were observed. The 3 consecutive tolbutamide injections induced hypoglycemia for 4 days (from ED 16 to ED 19). The postnatal performance after 3 consecutive tolbutamide injections in broiler embryos was also investigated. Body weight was lower in tolbutamide-treated chickens from hatch to 42d compared with sham (. P = 0.001) and control (. P < 0.001) chickens. Feed intake was lower in the tolbutamide group from hatch to 42d as compared with sham (. P = 0.007) and control (. P = 0.017) animals. In addition, at 42d, plasma glucose concentrations, after an insulin injection challenge (50?g/kg body weight), were higher in tolbutamide-treated chickens compared with the sham and the control group as were their basal glucose levels (. P value of group effect <0.001). In conclusion, tolbutamide treatment during the late embryonic development in broilers resulted in prolonged hypoglycemia in this period and negatively influenced the posthatch performance. 2015 Elsevier Inc.
