INTRODUCTION
Man improves his livestock by limiting the reproduction of inferior animals and by choosing superior animals for mating to produce the progeny, which constitute the next generation. The productive capacity and physical appearance of animal population can be changed greatly by selective breeding. A sound breeding programme is a necessary part of the total animal production system whether the breeder breeds his own replacements or purchases them from another breeder.
Selection and system of breeding constitute the only tools available to the breeder for improvement of animals, since new genes cannot be created, though they can recombine into more desirable grouping.
