The use of L-carnitine for improve reproductive performance of duck

There are many local breeds of birds in Iraq like chicken, turkey, duck, geese, quail and pheasant. Most of these breeds were not pure breeds as they were resulting in main part by hybridization with superior foreign breeds of each corresponding type of these birds. Studies that conducted on these breeds of birds specially local duck are so limited. So this work considered as a first work regarding study most features of productive, reproductive and physiological traits of both males and females of Iraqi local ducks. However, Iraqi local duck characterized with rather low productive and reproductive performance. For this reason the other goal of this study was to improve the productive and reproductive performance of Iraqi local duck by using L- carnitine.This work introduce very important information as regards the productive and reproductive criteria of duck in general with specification of Iraqi local duck. Furthermore, this work also introduce important information with relation to L- carnitine and its efficient roles in enhancing productive, reproductive and physiological performance of birds.
