Most of the future increase in livestock production is expected to occur in the tropical and subtropical regions of the world. Cattle are the most numerous of the ruminant species in the tropics and provide the largest quantity of animal food products. More than one-third of the world's cattle are found in the tropics. Disease is the major factor which prohibits full utilization of these regions for cattle production. Various infectious and transmissible viral, rick ettsial, bacterial, and particularly protozoan and helminthic diseases, are widespread in the tropics and exert a heavy toll on the existing cattle industry there. This uncontrolled disease situation also discourages investment in cattle industries by private and government sectors. In Africa alone, it is estimated that 125 million head of cattle could be accommodated in the tropical rainbelt if the disease and other animal husbandry factors could be resolved. The potential of efficient cattle production under more favorable conditions prompted various international agencies to establish a multi million dollar International Laboratory for Research in Animal Diseases (ILRAD) in Nairobi, Kenya, Africa. In South America, principal sites for raising cattle are shifting to the savannah lands because the more fertile soils are being used for crop produc tion, however, in the savannahs also, disease remains the most powerful deterrent in implementing the cattle industry.

Biotechnology is expected, by many observers, to have a significant impact on the world dairy industry over the next decade. In this timely volume, Lovell Jarvis analyzes the potential effect of two biotechnologies—multiple ovulation and embryo transfers (MOET) and recombinant bovine somatotropin (rbST—on the dairy industry around the world. According to Jarvis's research, the effects of these two technologies will vary greatly between the developed and developing nations. He predicts that the technologies will be most profitable for the developed nations, where their use will increase milk production and strengthen their positions in dairy export markets. Developing country dairy sectors will probably lose from the use of these two biotechnologies, as their own international trade position will be weakened, though their own consumers should benefit. Jarvis concludes his study with a look at alternative approaches that might improve the competitive position of developing countries in the dairy sector.

Dairy Science, Four Volume Set includes the study of milk and milk-derived food products, examining the biological, chemical, physical, and microbiological aspects of milk itself as well as the technological (processing) aspects of the transformation of milk into its various consumer products, including beverages, fermented products, concentrated and dried products, butter and ice cream. This new edition includes information on the possible impact of genetic modification of dairy animals, safety concerns of raw milk and raw milk products, peptides in milk, dairy-based allergies, packaging and shelf-life and other topics of importance and interest to those in dairy research and industry.
