Changes in serum lipids, serum glucose, and gonadal development during maturation of Colinus virginianus were determined in two trials. In Trial 1, sex, BW, and serum concentrations of total cholesterol, high, low, and very low density lipoprotein cholesterol, triglycerides, and glucose were determined every 2 d from 2 to 14 d and weekly from 21 to 49 d. Relative ovary or testis weights between 14 and 49 d were determined weekly. Body weight increased and all measured serum constituents changed in males and females between 2 and 49 d; however, relative testis weight decreased between 14 and 49 d. In Trial 2, sex, BW, cholesterol, and relative ovary and testis weights were determined in birds at 56 and 63 d of age. The distinctness of external sexual phenotype and its relationship to BW, cholesterol, and relative gonadal weight were also determined at 56 and 63 d. Body weight increased and serum cholesterol decreased in both sexes between 56 and 63 d, but had no association with the distinctness of external sexual phenotype. It was concluded that the development of external sexual identity in male and female Northern Bobwhite quail prior to sexual maturity was not related to changes in BW, gonad weight, serum lipids, or serum glucose before 63 d of age.
在两项试验中测定了弗吉尼亚鹑成熟过程中血清脂质、血清葡萄糖和性腺发育的变化。在试验1中，从2至14日龄每2天测定一次性别、体重以及总胆固醇、高密度、低密度和极低密度脂蛋白胆固醇、甘油三酯和葡萄糖的血清浓度，从21至49日龄每周测定一次。在14至49日龄期间每周测定相对卵巢或睾丸重量。在2至49日龄之间，雄性和雌性的体重增加，所有测定的血清成分均发生变化；然而，相对睾丸重量在14至49日龄之间下降。在试验2中，测定了56和63日龄鸟类的性别、体重、胆固醇以及相对卵巢和睾丸重量。还在56和63日龄时确定了外部性表型的明显程度及其与体重、胆固醇和相对性腺重量的关系。在56至63日龄之间，两性的体重均增加，血清胆固醇均下降，但与外部性表型的明显程度无关。得出的结论是，雄性和雌性北部鲍勃白鹌鹑在性成熟前的外部性特征发育与63日龄前的体重、性腺重量、血清脂质或血清葡萄糖变化无关。
