The following table summarizes the IGENITY profiles for the sires of our current crop of bulls. An explanation of each category follows.
Average Daily Gain
The profile result for Average Daily Gain identifies an animal's genetic potential for rate of gain, for both calves and post-weaning growth. Animals which score a 10 are capable of gaining an additional 0.81 lbs per day over animals with a score of 1: this means a potential 166 lb difference over 205 days.
Residual Feed Intake (Feed Efficiency)
RFI describes an animal's feed intake above or below its predicted needs for maintenance and growth. An animal with a low RFI score will eat less to achieve the same gains; gain more on the same amount of food; require less feed to maintain body condition as a mature adult.
Higher IGENITY profile scores represent animals that are more tender than those with lower scores.
Marbling Score and Quality Grade
Canadian AAA grading has the same minimum marbling requirements as for USDA Choice. The USDA marbling score is based on a 999 point scale. In a group of animals with an IGENITY profile score of "10" for marbling, the average marbling score can be expected to be 161 points greater than animals with a score of "1". The IGENITY profile for Quality Grade indicates differences in magnitude that marbling score will contribute to Quality Grade. More specifically, a group of animals with a Quality Grade score of "10" can be expected to have 64% more animals grade Canada AAA than a group of animals with a Quality Grade socre of "1".
Lean yield is an estimation of the percentage of the carcass that is red meat; it is not dressing percentage. When a carcass grades A or higher in Canada, it also is graded for yield. A group of animals with an IGENITY profile score of "10" for Yield Grade can be expected to receive a Yield Grade score that is 1.3 of a grade higher than animals that receive a score of "1". Lower IGENITY profile scores reflect higher percent red meat yield. Higher IGENITY profile scores reflect lower red meat yield.
Back Fat Thickness
In a group of animals with an IGENITY profile score of "10" for Back Fat Thickness, the average back fat is expected to be 0.37 inches greater than animals that score "1". Lower IGENITY profile scores indicate less external fat, while higher scores reflect more external fat. (A minimum of 2mm of back fat is required to Grade A or better in Canada).
In a group of animals with an IGENITY profile score of "10" for Ribeye Area, the average Ribeye Area is expected to be 2.6 square inches greater than animals that score "1". Lower IGENITY profile scores reflect smaller ribeye areas, with higher scores reflecting larger ribeye areas.
Maternal Traits - Heifer Pregnancy Rates; Stayability; Maternal Calving Ease
Heifer Pregnancy Rate indicates a heifer's chance of becoming pregnant over a normal breeding season, relative to other females. Stayability indicates the chance a heifer will remain in the herd until at least six years old, relative to other animals. Maternal Calving Ease is measured as the percentage of unassisted births - a higher value indicates greater calving ease.
Calm cattle are not just about handler safety - calm cattle eat more, have better response to vaccinations and preconditioning and are more tender. The IGENITY profile for docility indicates the animal's genetic potential to be calm, or to have calm offspring. Higher IGENITY scores for this trait indicate a higher likelihood that calves possess acceptable behaviour.
