RFI Raw Data for

B Bulls




Here is the data on our Lilybrook B bulls of the Canadian Hereford Associationís Residual Feed Efficiency Trial number 5.

Feed efficiency (RFI, RG, RIG) values have been calculated across contemporary groups (pens in this case), however bulls at this time can only be compared within pen. Comparison across pens can be conducted when estimated breeding values (EBVs) have been calculated. 

RFIFAT_A refers to residual feed intake adjusted for final off-test backfat thickness and has been calculated across contemporary groups. It is expressed in kg DM/day and can be converted to lb DM/day by multiplying the value by 2.2046. Negative RFI means superior feed efficiency compared to a positive bull.

 RGFAT_A refers to residual gain adjusted for final off-test backfat thickness and has been calculated across contemporary groups. It is expressed in kg gain/day and can be converted to lb/day by multiplying the value by 2.2046. it identifies bulls with superior growth potential and positive values have superior growth to negative values.

 RIGFAT_A refers to residual intake and gain adjusted for final off-test backfat thickness and has been calculated across contemporary groups. It is expressed in Standard deviations above the mean. Positive RIG values means superior feed efficiency and superior growth compared to a bull with negative RIG values.

 RIGFAT_A is perhaps the most meaningful data point to consider at this point in the project as it represents the residual feed intake AND the residual gain. In other words this represents animals with lower feed intake but are also high gainers. In this instance, the more positive the number the better.

Here are the Raw Data RFI values for Trial #5
