Buffalo meat from animals fed with agro industrial products in eastern amazon

The quality of buffalo (Bubalus bubalis) meat, finished in a silvopastoral system with feed supplementation in the Amazon, was evaluated. Five crossbred buffaloes were used in each treatment with supplements of two different feeds, elaborated with agroindustrial by-products of coconut or palm oil extraction and a traditional one based on corn and soy. Physical, physical- chemical, microbiological, and sensorial analyses were performed on the Longissimus dorsi muscle, and the results were analyzed through the analysis of variance and averages, compared by t-test. The coconut and palm treatments had the largest percentage of saturated fatty acids. On the other hand, the ω6/ω3 ratio were within the healthy dietary standards. According to the results of pH, color, and shear force analyses, the meat was classified into RFN (Red, Firm and Normal) or ideal standards. Through subjective and objective analyses, the meat of the treatments was considered tender. The quality of the meat produced is due to the farming system used. Moreover, the use of agro-industrial waste minimizes environ- mental impact and the cost of animal feed, thus increasing the revenue of the rural worker.
