ANALYSIS OF THE CHICK GROWTH CHARACTERISTICS BY MEANS OF ASYMETRIC S-FUNCTION

Abstract

U radu su istraživane fenotipske značajke rasta Arbor Acres pilića do 6. tjedna odnosno 10. tjedna. U istraživanja je uključeno po 30 pilića ženskog odnosno muškog spola. U modeliranju krivulje rasta upotrebljena je asimetrična S-funkcija. Pomoću navedene funkcije utvrđene su karakteristične faze rasta i točka infleksije. Istraživanje je pokazalo da je asimetrična S-funkcija prikladna i za prognozu životne mase pilića do 10. tjedna.This article deals with the analysis of phenotypic growth characteristics of the Arbor Acres chicks till the 6th, i. e. 10th week of age. The study included 30 female and male chicks. An asymmetric S function was applied as a growth curve. The characteristics of the growth stages and the point of inflection were determined. The study showed that the asymmetric S-function was adequate for forecasting the weight, i. e. live mass of the chicks till the 10th week of age
