ADG, average daily gain; DFI, daily feed intake; RFI, residual feed intake; FCR, feed conversion ratio; DC E, digestibility coefficient of energy; DC N, digestibility coefficient of nitrogen; DC OM, digestibility coefficient of organic matter.
Correlation not significantly different from zero according to the 68% confidence interval determined by subtracting and adding one standard error to the estimated heritability.
NE, Not estimable.
