Genetic parameters for fertility and production traits in Red Angus cattle.

Journal of animal science - 29 Sept 2018

Boldt Ryan J, Speidel Scott E, Thomas Milton G, Enns R Mark

Abstract excerpt

Heifer pregnancy (HPG) and Stayability (STAY) are female reproductive traits that have EPD reported by the Red Angus Association of America. Challenges arise when making genetic predictions for these traits. Specifically, HPG and STAY phenotypes can only be collected on females retained in the breeding herd and have low heritability estimates. Additionally, STAY is measured late in an animal's life. The objective...
