title: [Mathematical treatment of a growth series for body mass in turkeys (male, female)].
abstract: Body weight values for 60 gobblers and 60 hens of 3 series of the turkey (Meleagris gallopavo silvestris) after data from Johnson (1953), Mosby and Handley (1943) are submitted to nonlinear regressions for selected functions of organismic growth. The results are compiled in 3 tables confronting natural with approximated and smoothed values. The tables imply the parameters of the growth functions and characteristical data as well as the amounts of deviations. Graphs show the body weight development for both sexes and the growth increase. The ratio of the amounts of body weight in the inflexion point to the theoretical final values ranges from 33 to 64% depending on the series and the growth function chosen.
