Abstract:
... Buffalo milk is economically important, and an understanding of the genetic basis of milk production traits may facilitate buffalo breeding for this purpose. In this study, polymerase chain reaction-single strand conformation polymorphism was used to analyze polymorphisms in prolactin receptor (PRLR) exons 3, 5, 7, and 10 in Murrah, Nili-Ravi, and crossbred buffaloes and Holstein cows. A site in P ...
