The artificial of incubation of spot-billed duck eggwas studied from Mach to May 1997 at the Zhengzhou zoo. The paper mainly researched the of spot-billed duck: morphology of egg; artificial incubation; rate of loss and so on .The result shows that, the fresh weight of the egg weight is 61.35±1.89g;egg length is 56.84±1.30 mm;egg width is 43.55±0.97mm;The incubation period of spot-billed duck is 28.04±0.94days.The egg loss weight during incubation. The regression equation of egg weight loss (Y) and ...
