Mouktar Abd-Ellatif, S. El Kaschab, Y. A. Afifi


During recent years, there has been an increase in the rate of application of progeny test to improve livestock production. Comparative study was done to detect the most reliable and simple method to study the genetic transmitting ability of Damiatta Bulls using different methods of progeny testing equations. It was clear that the ranking of the sires was almost the Same according to the different equations used. It is possible to apply any one of the three equations to predict the breeding value of Damiatta Bulls according to early information of their progenies.
