O objetivo do trabalho foi efetuar a comparação das principais espécies de interesse agropecuário, em relação à eficiência de conversão das dietas em produtos de origem animal (carne ou ovo), produção de resíduo e potencial de emissão de metano, a partir da fermentação dos resíduos. Para isso, foram selecionadas cinco espécies de animais durante a fase de produção: 1) suínos, do nascimento ao abate (peso vivo (PV) final de 90 kg) ; 2) bovinos, do desmame ao abate (PV: 520 kg); 3) caprinos, do desmame ao abate (PV: 30 kg); 4) aves, durante toda a fase de postura (14,7 kg de ovos); 5) frango de corte, do nascimento ao abate (PV: 3,1 kg). Para a estimativa dos parâmetros propostos, foram medidos os dados do desempenho e efetuou-se a biodigestão anaeróbia dos dejetos produzidos pelos animais. de maneira geral, os dejetos dos ruminantes apresentaram altas concentrações de fibra e baixos potenciais de produção de biogás; no entanto, o menor desempenho destes animais na conversão do alimento em produto e a maior produção de dejetos fizeram com que eles apresentassem maiores produções de metano por kg de alimento produzido.

The global growing demand for food coupled with the direction of eating habits for products of animal origin, become even more necessary the search for alternatives to increase production. In this way, improve animal performance through the use of ionophores has become an effective measure to increase production and profitability of farms. Among the ionophores, monensin is the best known so far, as to their effect on the pattern of rumen fermentation and its consequences on animal production, especially by improving the quality or quantity of nutrients available for absorption through the gastrointestinal tract and consequently the performance of ruminants

Proteins of animal origin are among the most consumed foods in the world, this scenario highlights the pig production, providing much of the daily protein intake worldwide. Brazil has significant numbers in the production and export of pork to stand among the first in the world marker. Several diseases such as brucellosis, can configure a threat to this sector. Brucellosis in pigs is an important disease and zoonosis once it is the cause of great economic losses by making the species vulnerable to sanitary barriers as well as putting at risk the health of attendants of farms, slaughterhouses employees and consumers. Pigs slaughtered in slaughterhouses approved by competent organs guarentee the safety of employees, in the flowchart of slaughter, and consumers, but illegal slaughterhouses pose risk to public health

Brazil is one of the largest producers of animal protein. In 2010, the production of meat (beef, pork and poultry) was estimated at 24.5 million tons and 75% was consumed in the country. The meat is a primary source of water and fat and contains between 20% and 35% protein, providing all essential amino acids and several micronutrients and vitamins. Due to the large consumption of this food, its quality is extremely important and the research of some indicators microorganism become essential in order to ensure the hygienic and sanitary quality, indicating contamination of fecal origin, with the possible presence of pathogens or to identify food spoilage. Thus, the aim of study was to determine the microbiological quality of 90 samples handled meat products and pre- prepared marketed in Botucatu city, according to the parameters required by ANVISA (RDC 12, 2001). Among the samples analyzed, all of them were negative for Staphylococcus coagulase positive and were within the limit allowed by ANVISA for the Clostridium sulfite reducer (up to 3 x 103 CFU/ g). The presence of Salmonella was confirmed in only one sample (1.1%), against to the legal parameters. About thermotolerant coliforms, 54.4% of the samples were outside the acceptable limit by law (up to 5 x 103 MPN/g). Therefore, the presence of these microorganisms indicates inadequate hygiene conditions of foodhandlers and equipment used in the, which are considered inadequate for consumption
