| Research Abstract |
In cattle oxytocin might be involved in the regulation of behavioral and physiological stress responses in the brain. We showed that neonatal oxytocin could be involved in the behavioral development in calves. Moreover, our data suggested that oxytocin receptor gene promoter region polymorphisms and CD38 single nucleotide polymorphism might be influenced stress sensitivity, social affiliation, and milk production in cattle. These findings help to develop new breeding strategy focused on adaptability to their environment in cattle.
