Early-life milk production traits predict lifetime milk yield and support replacement decisions in Holstein, Jersey and Crossbred dairy cows under subtropical conditions

Veterinary and Animal Science
Improving lifetime milk yield through the early identification of superior replacement animals is a key objective of sustainable dairy production systems. This study investigated the potential of first-lactation performance indicators to predict lifetime

Detection on OAR7 of QTL affecting fat and protein yields in dairy sheep

Italian Journal of Animal Science, 2010
The objective of this paper was identifying QTL that affect fat and protein yields in dairy sheep independently of milk yield. Data were collected in an experimental flock of 887 ewes organized in a daughter design. QTL detection focused on OAR7 where 13
