Growth and morphologic development of juvenile rock partridge, Alectoris graeca Accrescimento negli stadi giovanili della coturnice, Alectoris graeca


Growth and morphologic development of juvenile rock partridge, Alectoris graeca Accrescimento negli stadi giovanili della coturnice, Alectoris graeca



Rivista Italiana di Ornitologia 66(1): 37-44



ISSN/ISBN: 0035-6875

The authors report the results of an experimental investigation on the growth and morphologic development of Alectoris graeca from its birth up to an age of 20 weeks. It is demonstrated that the growth of this species (and probably also of other birds) can be described by a logistic curve of the type. P-t = H-o H/1+K C-td where: P-t = weight in grams; t = time in days; H-o = lower limit of the curve ; H = upper limit of the curve ; K and C = constants; d = constant relative to the increase of time, depending from the width of the time intervals on which the parameters are calculated.
