蓝山灰鹅生态之研究

对湖南省蓝山县的地方良种灰鹅进行了研究,测定了体重、体尺、体温、脉搏、呼吸次数、血液学参数、产蛋性能、屠宰率、羽绒产量等。经对该县不同生态环境中的灰鹅进行比较,发现山区灰鹅在体形外貌、成年体尺、体重、体温、脉搏、呼吸及血液学指数等方面与平原地区灰鹅没有明显差异,但生长发育较慢(P<0.05)、开产迟(p<0.05)、产蛋率低,但羽绒产量和孵化率皆显著高于平原地区(P<0.01和P<0.05),母鹅利用年限也较长(P<0.05)。

Research on Ecology of lanshan Grey Geese

The authors made a study of local fine birds of grey geese in lanshan county of Hunan province, and determined their body weight, body sizes, body temperature, heart beats, breath rate, the parameters of hematology, egg production performances, slaughter percentage and feather production, etc. Also, comparisons of grey geese were made in different ecological environments in the county. it was found that there were no apparent differences in body conformation, adult body size, body weight, body temperature, heart beats, breath rate and parameters of hematology in grey geese between in mountain area and plain area, but the mountain grey geese grow and develop slowly (P<0.05) with late egg laying (P<0.05) and low egg production percentage, but whose feather production and hatching percentage are apparently higher than those of plain grey geese (P<0.01 and P<0.05) and female geese have a longer life span(P<0.05).
