Growth of body mass, femur, tibiotarsus, and tarsometatarsus length as well as the diameter of muscle fibers in the M. pectoralis were measured in (Large White) female turkeys between birth and day 224. Growth-specific approximations were established with the Janoschek function as modified by Sager (1978) and with the Logistic function. While the Janoschek function fairly described the growth of the turkey, the Logistic function throughout gave beginning values that were too high and theoretical end values that were too low. Of the five growth parameters that were measured, the diameter of the muscle fibers showed its maximal rate of growth first on day 21. The following decrease in growth rate took the following sequence: length of tarsometatarsus, femur, and tibiotarsus, diameter of muscle fibers, body mass. 99% of growth had occurred in the tarsometatarsus length on day 109, femur length on day 117, tibiotarsus length on day 138, diameter of muscle fibers on day 166, and the body mass on day 231. A comparison of this growth with that of other domestic fowl showed close relationships between the way turkeys and chickens grow.
在出生至224日龄的(大白)雌性火鸡中,测量了体重、股骨、胫跗骨和跗跖骨长度以及胸肌肌纤维直径的增长情况。采用经Sager(1978年)修正的雅诺谢克函数和逻辑函数建立了特定生长近似值。虽然雅诺谢克函数较好地描述了火鸡的生长情况,但逻辑函数始终给出的初始值过高,理论终值过低。在所测量的五个生长参数中,肌纤维直径在第21天首先显示出其最大生长速率。随后生长速率的下降顺序如下:跗跖骨长度、股骨、胫跗骨、肌纤维直径、体重。在第109天,跗跖骨长度完成了99%的生长;在第117天,股骨长度完成了99%的生长;在第138天,胫跗骨长度完成了99%的生长;在第166天,肌纤维直径完成了99%的生长;在第231天,体重完成了99%的生长。将这种生长情况与其他家禽的生长情况进行比较,结果表明火鸡和鸡的生长方式之间存在密切关系。
