Genetic parameters for milk yield and lactation persistency in the three first parities of Iranian Holstein cows

Genetic parameters for milk yield and lactation persistency in the three first parities of Iranian Holstein cows

Background: Lactation persistency influences cow health and reproduction and has an impact on the feed costs of dairy farms. Objective: To estimate (co)variance components and genetic parameters of 100- and 305-d milk yield, and lactation persistency in Holstein cows in Iran. Methods: Records collec...
