Abstract

The public policies in health suggest population-wide higher intakes of polyunsaturated fatty acids, and lower intakes of fat saturated. The meat and fat from ruminant animals typically presents great amounts of saturated fatty acids and low amounts of polyunsaturated fatty acids. Thus, research studies aiming at the production of meat with beneficial characteristics to human health are increasingly relevant, given the role of this food as the main nutritional protein source. Therefore, scientific studies are crucial to provide knowledge to consumers allowing them to assess the pros and cons of eating beef which in turn, has a tremendous importance for the global economy. However, even with all the advances in studies on cattle, there is still a gap in the exploitation of the current knowledge of the quality of meat from Bos indicus animals reared in different Brazilian production systems and with distinct finishing strategies. The objective of this study is to analyze the results obtained by our research group, since a large number of data are generated and results are compiled, which provide us with greater consistency in the responses that are not yet known. This gap can be filled by a meta-analysis with data originating from our studies on meat quality conducted with the Bos indicus species. The database to be used to develop the meta-analysis is from data generated on the FAPESP Project 06/57774-4, 07/53733-4, 09/06472-6, 11/00060-8. The overseas research internship will take place at the Universidad de Zaragoza, Espanha, under the guidance of Profa. Dra. María del Mar Campo Arribas. The Dra. María del Mar Campo Arribas is an important researcher in the Departamento de Producción Animal y Ciencia de Alimentos - Universidad de Zaragoza, where her research programme explores: Effect of productive factors on carcass quality and meat from ruminants; Quality of fat, fatty acids and aromatic compounds and sensory analysis and consumer study. Thus, the candidate for the internship will have the opportunity to learn to develop the proposed project and will bring new knowledge to share with his research group. (AU)
