Summary On the growth of the skeleton, the body mass and the diameter of muscle fibers in the turkey ( Meleagris gallopavo ) from birth to day 224 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 S ager (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.
