DSD 7.3 | Generate More Grade 1 Embryos
Episode 70
Monday, 16 March, 2026
Embryo transfer has become increasingly popular on US dairy farms to rapidly advance the genetic profile of the herd. This month’s feature article looks at the associations between fertility traits on the success of embryo transfer. Fertility traits such as daughter pregnancy rate (DPR), cow conception rate (CCR) and heifer conception rate (HCR) are consistently classified with low heritability. However, this retrospective study takes a deep dive into the data stored at the Council of Dairy Cattle Breeding (CDCB) to use the statistical power of dairy farmers data. There, the researchers were able to find a clear impact of these traits on the success of an ET program and long term impact on herd fertility. Because ultimately … we’re just interested in more calves on the ground, so listen in to better understand how data is improving ET fertility setbacks.
