 ABSTRACT

Genetic improvement in productivity per animal in the shortest possible time is the main aim of animal breeder. Though conventional selection and mating schemes have given significant contribution in genetic improvement of livestock in developed world, but their impact in developing countries like India have been on lower side. This is because of too complex breeding programs in terms of logistics, technology and other resources which is leading to wrong breeding objectives, negligence the potentials of various indigenous breeds of livestock. Nucleus herd breeding schemes are beneficial in many developing countries where the selection of breeding stock is concentrated in a few herds from which the selected animals are spread to other herds. Hence a breeder can achieve greater rate of improvement (up to 15- 25%) because of high selection intensity. The annual genetic progress in MOET – ONBS was 4-6 % higher as compared to classical progeny testing schemes and this response was reduced to 1- 2% when the nucleus was closed. It allows more rapid improvement with limited resources & data recording, which is practically most suitable for developing countries. ONBS (in combination with MOET) allows higher selection intensity in females, increases the number of viable offspring that can be obtained from a single elite female.

Key words:Open nucleus breeding schemes (ONBS), Multiple ovulation embryo transfer (MOET), Adult MOET, juvenile MOET, Hybrid or mixed MOET.
