原始语种摘要: Abstract(#br)In order to describe the growth curves of live body weight (BW), body length (BL), height at withers (HW) and hearth girth (HG) in Caspian horses, six non-linear mixed growth models (Brody, LogistiC., Gompertz, Schumacher, Von Bertalanffy and Negative exponential) were used. The data set comprised 129 records of BW and biométrie traits (made up of 54 for males and 75 for female horses) which were measured weekly from birth to 32 weeks of age in the premises of the Animal Science Department, Agricultural and Natural Resources Research Center of Guilan, Rasht, Iran. Each model was fitted to weekly records of horses using the non-linear mixed model procedure (PROC NLMIXED) in SAS and the parameters were estimated. The mixed models were tested for goodness of fit using Akaike’s...
