Abstract: The present study was undertaken to determine the meat characteri-stics of breeds:Sichuan white Geese(S), Western Anhui White Geese(K), Landes Geese(L), Huoyan Geese(H) and their crosses HS, LS and KS. The trail was divided into two groups, one is the free-range group which includes all the 7 combina-tions and supplemented feed only in the morning and at night, another is house-keeping group which consists of KK, SS, HS and KS. The former were slaughtered at 70 and 84 days of old, the latter at 60 and 70 days of old. The results indicate that the freerange geese were heavier than those of house-keeping group. Data of the slaughtered indicates that eviscerate rate of 60 days was evidently lower than that of 70 days:By campering 70 days with 84 days in eviscerate rate, the latter increase was low. At the age of 70 days. difference existed between the different geese's rearing ways, but not significant(P>0.05). The free-rangeHS had much more hybrid vigor than the others, and LS was the next but KS had not heterosis of body weight. The results suggest as follows:the best market time is 9-10 weeks of age:hybrids, by using the Sichuan White Geese as the mother, gained higher breast plus leg muscle rate than the pure breed SS; it is not necessary to produce meat goslings by house-keeping instead of freerange. And nutrition and breeding of geese were dicussed according to the result.
