The Application of Biotechnology on Livestock Feed Improvement

Today demand for livestock products are becomes increasing because of the increasing world human population, income growth and increase of urbanization [1]. For example, total meat production in the developing world was tripled between 1980 and 2002, from 45 to 134 million tons. Demand for meat will grow only 0.6% in developed world compared with an annual increase of 2.8% in developing world. Most food of animal origin consumed in developing countries is currently supplied by small-scale and mixed crop-livestock producer or by pastoral livestock keepers by producing in traditional way [2].
