Abstract

This review work is focused on the theory of genes and chromosomes as they occur and vary in members of populations. Conservation of local breeds of farm animal genetic resources should be a part of animal management and the communities should be informed by pertinent parties for the distribution, structures, and trends, productive and adaptive performances of populations of the existing breeds. Conservation farm animal genetic resources still not practiced and managed well in the whole or all over the country except for few breeds such as three cattle breeds and one sheep at research centers. The responsible constraints are lack and gap (is avail) of information of about farm animal genetics resource, climate change the anther driving force to change animal production system, increase the exposure of breed populations to un familiar epidemic disease and lack of awareness of AnGR among decision makers and lack of consultation with livestock keepers and other relevant stake holder. But there are also opportunities in the country such as practice in little research centers. Farm animal genetic resources conservation must be practice by well-designed management, support by national breeding policy strategy and economic wise to attain the food security of many societies finally to the GDP of the country as the whole. Farm animal genetic resource information should be accessible available for every interested specially for animal keepers and other stakeholders as well. Perceptions and thought s of the community should include during design and implementation of animal conservation in the country. Animal conservation must have support by government and non-government organization to facilitate, fund and other related aspects.
