Two kinds of the fat-soluble dye, Sudan black and red, were intravenously injected on alternate days into layers aged from 5 to 23 months to study the growth pattern of the ovarian follicle in relation to aging. Results indicated: 1) the length of the rapid growth period showed a tendency to shorten during 5 to 11 months, then to lengthen from 15 to 23 months of age; 2) there was a continuous increase in follicular volume at ovulation with the progress of age; 3) the growth rate (degree of curvature of the growth line calculated in each follicle) was low at 5 months, increased from 8 to 11 months, and remained constant thereafter; 4) during the first year of age, the number of growing follicles in the ovary decreased gradually, whereas the total amount of daily yolk deposition increased. During the second year of age, both the number of growing follicles and total yolk deposition remained constant.
在5至23月龄的蛋鸡中，每隔一天静脉注射两种脂溶性染料苏丹黑和苏丹红，以研究卵泡生长模式与衰老的关系。结果表明：1）快速生长期的时长在5至11月龄时呈缩短趋势，之后在15至23月龄时延长；2）随着年龄增长，排卵时卵泡体积持续增加；3）生长速率（计算每个卵泡生长线的曲率）在5月龄时较低，8至11月龄时增加，此后保持恒定；4）在1岁时，卵巢中生长卵泡的数量逐渐减少，而每日卵黄沉积总量增加。在2岁时，生长卵泡的数量和卵黄沉积总量均保持恒定。
