Abstract:

To perfect the breed characteristics data and investigate the changes of serum biochemical parameters in Shitou goose with strong broodiness during reproductive cycle, eleven serum biochemical parameters were measured on 45 adult female Shitou geese at different stages. The results were as follows: (1) The concentrations of serum calcium and phosphorus ions were highest during laying period, and the difference was significantly. (2) The level of ALP in laying was increased by 39.49% (P<0.05) and 12.70% respectively than that in incubation and laying cessation. (3) The levels of TP, CERA, UA and CHO were not significantly at different stages, but the level of BUN was lowest during incubation, and it was decreased by 24.49% (P<0.05) and 34.69% (P<0.05) respectively than that in laying and laying cessation. The results provided evidence to establish serum biochemical parameters of Shitou geese during reproductive cycle, which might provided a reference in feeding management, breed protection and selection, prevention and treatment of disease and so on.
