摘要

ABSTRACT The experiment used 100 grey partridges ( Perdix perdix L.), which were reared first in confinement and later in aviaries. Partridges were lighter and had greater body dimensions at 36 weeks compared to 12 weeks except for trunk length. Older birds showed greater values ( p> 0.05) of compactness and lower values of massiveness and long-leggedness. Significant differences were found for keel length in females. At 36 weeks, male and female partridges had significantly greater total intestinal length, males had significantly longer small intestine and rectum, and females were characterized by significantly longer caeca and greater ( p< 0.05) intestine to body length ratio. Older birds had significantly greater gizzard weight and percentage and heart percentage (males and females), as well as significantly lower liver weight (males) and spleen weight and percentage. The present study provided information on the growth and development of farmed grey partridges before release into the natural environment.
