摘      要：A trial of artificial incubation to great bustard (Otis tarda ) egg was conducted from 1995 to 1997.Among the 45 collected eggs, 28 eggs were fertilized and 26 hatched, with fertilizing rate 62.2% and incubation rate 92.85%. The mean Incubation-days for great bustard egg was confirmed as 24.4(21-28 days) with the formula for caculating fresh egg weight (W=KwLB2) and that for counting the incubated days by parents birds in field (ld=24(w-y)/0.144y). The proper incubation temperature and relative humidity were 36-37.8℃ and 50-65%.respectively. The egg weights and egg size average 130.45 g and 77.411.42 × 55.5 ± 0.65-mm respectively. The total weight loss of egg was 18.38±0.646 g, daily weight loss 0.748±0.071g in the incubation time. with a weight loss rate of 13.6±1 .02%. A linear regression equation to discribe the relationship between the egg weight and incubation days, was built, y=130.73-0.619± (x--incubation day, y--egg weight). r=-0.978. Twenty-eight hours were nassassary for great bustard embryo to complete the fledging when the were put in gas room. The mean weight of fledglings was 86.3±3.29 g(n=26).
