Genetic evaluation plays a crucial role in improving dairy cattle breeds like Hardhenu, particularly by assessing test day milk records and confirmation traits. This study aimed to evaluate the genetic parameters of these traits to enhance breeding strategies. Test day milk records were analyzed using random regression models to estimate heritability and genetic correlations across lactation stages. Confirmation traits were assessed through traditional linear models to determine their heritability and relationships with milk production. Results indicated significant heritability for both milk production and confirmation traits, suggesting potential for genetic improvement through selective breeding. The findings underscore the importance of integrating genetic evaluations into breeding programs to enhance the overall productivity and conformation of Hardhenu cattle.
