Genetic evaluation of age at first calving and days open under different censoring scenarios in Iranian Holstein cows.

Tropical animal health and production - 10 Aug 2022

Atapour Marzieh, Razmkabir Mohammad, Mokhtari Morteza

Abstract excerpt

The present study aimed to investigate the effect of censoring, the situations in which incomplete at the time, out of range, and/or delayed records were considered, in the estimation of genetic parameters for age at first calving (AFC) and days open (DO) in Iranian Holstein cows. The dataset included 281,772 records collected from 1991 to 2019 by the Vahdat Cooperative Company, a pioneer dairy farm in Isfahan...
