In this time of rapid technological advancement, animal breeding is entering a new era. As demonstrated in the pig and dairy industries, gathering and incorporating vast amounts of genomic data into the genetic evaluation accelerates progress.
Female genotypes are rare and valuable, especially to predict maternal traits such as stayability and maternal calving ease. Furthermore, genotyping entire herds improves genomic evaluations by reducing bias created when only the best cattle are genotyped. Therefore, gathering massive amounts of genotypes on entire cow herds will improve the genomic predictions and rate of genetic progress.
Considering these facts, the ASA developed the Cow Herd Roundup (CHR), a program to provide inexpensive genotyping to maintain whole herds DNA tested. Tests cost $25 for a genomic profile (50K including parentage) if the entire cow herd is genotyped (a $25 savings). Breeders who submit cow weights with either body conditions scores or hip heights receive an additional $5 off per test — an amazing price of $20/sample for something breeders currently pay $50 per test for. This offer is only available up to 50,000 samples so don’t delay.
Benefits to participating members:
The table below shows how many progeny records it takes for an animal without genomics to have the same BIF accuracy as an animal with genomics but no progeny. In other words, EPD on a genotyped 1-month-old calf will be as accurate as an animal with birth weights on 21 calves, weaning weights on 22 calves, etc. The carcass traits represent actual carcass records, not ultrasound records. You may notice the maternal calving ease gets the least boost from genomics. This is due in part to such few females being genotyped.
It is important to note, continued collection of phenotypic records remains a vital part of genetic predictions. DNA testing will never replace the need to record and submit phenotypes.
As this is part of research and development..... not a definite timeline for reporting results.
