Selection criterias of stud bull

Breeding studies planned detailed and clearly is a prerequisite for success in accordance with the examination of livestock breeding systems. The study schedule is named “breeding program”. The aim of breeding program is increasing the efficiency of animal products and improving the quality of the product. The breeding program of a certain population is started with the determination and analysis of variation in terms with the considered productivity and the bulls having the required properties are seperated as studs. Thus, these individuals in the herd will be given the opportunity to give more offspring than others. Selection of stud bull is the most important factor in developing livestock sector. Stud herds transfer high genetic characteristics to the offspring, that makes the herd more efficient so that the country and managements can make a profit. In this process, regarding the selection criteria and to be known how to evaluate these criterias, is very important, in selection of stud bulls. Especially, selected semen for artificial insemination, must be analyzed for its carried characteristics and most importantly the suitability to the herd should be determined. In this review, methods for selection of stud bulls and how the evaluation should be made to the semen, is tried to be explained
