Research Note: Developmental changes of glucose metabolism are associated with insulin signaling in goose embryo.

ABSTRACT: This study aimed to investigate whether the developmental changes in glucose metabolism were associated with insulin signaling in the middle and later stages of goose embryos. Serum and liver were sampled on embryonic day 19, 22, 25, 28, and day of hatchment, with 30 eggs at each sampling time point, and 6 replicates of 5 embryos. The embryonic growth traits, serum glucose, hormone levels, and the hepatic mRNA expressions of target genes related to glucose metabolism and insulin signaling were measured at each time point. Relative body weight, relative liver weight, and relative body length decreased linearly and quadratically from embryonic day 19 to day of hatchment, while relative yolk weight decreased linearly from embryonic day 19 to day of hatchment. Serum glucose, insulin, and free
