^a–g

LSMeans values with PSEM (n=36 chicks/experimental group) in the same row with different superscripts are significantly different (p<0.05)

1: y(t)=a·e^{−b·e−c·t} with y=body weight at time t and the regression coefficients a (asymptotic limit=adult body weight), b and c

t_max: equivalent to the point of inflection (time of maximum weight gain)

R²=coefficient of determination; RSD=residual standard deviation; PSEM=pooled standard error of mean; MDWG=maximum daily weight gain

n.s.=not significant
