BMC Genomic Data

Table 1 Descriptive Statistics: Descriptive statistics for three feed efficiency traits and estimates of variance components and heritability from linear model analyses incorporating either numerator or genomic relationship matrices.

From: Impact of reduced marker set estimation of genomic relationship matrices on genomic selection for feed efficiency in Angus cattle

^aAverage daily feed intake, AFI; residual feed intake, RFI; and average daily gain, ADG; all measured in units of kg/d.
^bDNA samples were available on only 698 of the 862 phenotyped steers. Variance components for these three analyses were estimated using the GRM.
