Cross-breeding between Madura cattle and exotic breeds (exotic cows) occurs in Madura area. The reality in the field shows that the cross-breeding occurs between Limousin cow and Madura cow and the result of the breeding is called as Madrasin cow. One of factor that influences the animal?s growth is Growth Hormone Receptor (GHR). GHR is needed by Growth Hormone (GH) to carry out its effects on target tissues. The purpose of this study is to identify the profile of Growth Hormone Receptors in Madrasin cow. This research was conducted on farmers in Bangkalan, East Java and the Center of Veteri…
