Although there is a large population of domestic cattle in the developing countries of the tropics, those productivity is very low and it is difficult to rely upon animal production for the supply of high quality protein for human food. It is essential to be able to alleviate the deleterious effect of the hot and humid climate and diseases which prevail in the tropics in order to improve the productivity of native cattle. For this reason, attempts have been made to implement cross-breeding schemes between European cattle which are highly productive and zebu cattle which are strongly resistant to heat and diseases, and various kinds of cross-bred cattle that can adapt to the climatic conditions of the various areas in the tropics have been developed. However, such undertakings have not always been successful and further efforts are necessary for making the best use of the superior characteristics of the two breeds, through the improvement of the methods of cattle breeding in the tropics.
