At the same group deserves attention the consumption of buffalo that occurs almost entirely in India where beef consumption is forbidden by Hindu religion 83 of India population . India and Pakistan are also important producers of sheep and goats. Similarly horse consumption is concentrated in Asian countries. Rabbits are produced mostly in China Venezuela and Italy. China also concentrates the production of geese goats ducks and sheep. a b Fig. 2. Distribution of animal protein production in the world in 1975 a and 2008 b Source FAO 2010 adapted by the authors. Globally a great dynamic in animal protein production can be noted. Even being less expressive regarding total production the highest growth rates in animal protein production are focused on meat of birds. Among the most important sources chicken may be highlighted showing an annually growth of 4.1 over the past 10 years. The negative highlight is related to beef which presented one of the lowest growth rates 1.1 . In an intermediate form pork production increased in the order of 2.52 . Since 1975 year after year poultry industry is consolidating itself as one of the most important animal protein sources for the population. According to data from the United States Department of Agriculture USDA world production of broilers grew consistently over the past 35 years from 10.6 million tons in 1975 to 71 million tons by the end of the first decade of this century. Brazil has a different dynamic for meat production. Unlike the rest of the world the main animal protein is chicken 41.31 beef 36.49 pork 12.19 and eggs 7.38 which represent 97.37 of total produced in the country Figure 3 . As a result of these factors one should expect a continued
