【摘要】 对2000~2002年成都动物园人工孵化及人工育雏的8只大紫胸鹦鹉的生长发育情况进行了125天的观察分析。经回归分析表明,大紫胸鹦鹉雏鸟的平均出壳重为12.4±0.4 g,人工饲育下56日龄体重达到最高值,平均体重为259.55±2.45 g;鹦鹉体重(W)与日龄(D)的关系为W=259.55/(1+45.2227e-0.1297D)。出壳时,嘴峰短于嘴裂,长度分别为7.75±0.25 mm和10.0±1.0 mm;35日龄时,嘴峰长度超过嘴裂,其长度分别为19.0±1.0 mm和18.75±0.75 mm;110日龄时,嘴峰和嘴裂的长度达生长期峰值,其长度分别为29.0±1.5 mm和25.0±1.5 mm;嘴峰长和嘴裂长与日龄的关系分别为L=29/(1+4.1023e-0.0636D)和L=25/(1+1.7967e-0.0473D)。出壳时,跗跖长于中趾,长度分别为8.25±0.25 mm和7.25±0.25 mm;15日龄时,中趾长度超过跗跖,其长度分别为13.5±0.5 mm和13.0±0.5 mm;100日龄时,中趾与跗跖的长度达到峰值,其长度分别为24.5±0.5 mm和30±1.0 mm;跗跖和中趾长与日龄的关系分别为L=24.5/(1+1.4536e-0.0569D)和L=30/(1+2.941733e-0.0638122D)。雏鸟孵化时,翅长10.5±0.5 mm;30日龄长出飞羽羽芽,平均翅长40.5±2.5 mm,35日龄羽鞘破樱,120日龄平均翅长201.0±6.0 mm;翅长与日龄的关系为L=201/(1+30.0624e-0.0780D)。30日龄生出尾羽羽芽,125日龄时尾长为190.0±8.0 mm;尾长与日龄的关系为L=190/(1+177.1306e-0.07533D)。更多还原

【Abstract】 The growth of 8 Derby’s parakeets(Psittacula derbiana) with artificial feeding was observed from 2000 to 2002 for 125 days.The results indicated:the average body weight of the squabs was 12.4±0.4g.The average weight of the chicks on the 56th day was 259.55±2.45g.The relationship between weight and days was W=259.55/(1+45.2227e-0.1297D);the relationship between the length of culmen and days was L=29/(1+4.1023e-0.0636D);the relationship between the length of rictus and days was L=25/(1+1.7967e-0.0638D);the relationship between tarsal spur and days was L=24.5/(1+1.4536e-0.0569D);the relationship between the length of the middle toe and days was L=-30/(1+2.947e-0.0638D);the relationship between the length of the wing and days was L=-201/(1+30.0624e-0.0780D);the relationship between the length of the tail and days was L=190/(1+177.1306e0.0753D).更多还原
