[QUOTE="wbvs58, post: 1828765, member: 16453"] I have been getting genomics done on the heifers I retain right from when they first became available through Angus Australia. I always save the before EBV's so I can compare to the genomic enhanced EBV'. Most of the time there are only subtle changes up or down to the EBV's. I had two heifers I had to collect new samples on as they were only able to do the parent verification but apparently the sample had poor genotype. I got the new results the other day and boy were they enhanced. On one of them the BW went from+4.7 to +0.4. Calving ease direct went from -5.9 to a calving ease specialist of +6.7. The 200 day wt went from 63 to 42, 400 day wt 114 to 89, 600 day wt 150 to 116. Milk went from 24 to 32. To my thinking looking at the phenotype of the heifer and of her mother and from what I know of the sire I think the original EBV's would be pretty representative of the heifer. She is by Mead Magnitude out of a Connealy Earnam cow, both being fairly large animals. It will be interesting to see how this heifer goes and raises a calf whether her performance is more indicative of the old EBV's or the new. I am going to give Angus Australia a ring and see if their experts can shed any light on what happened. Ken [/QUOTE]
