Resumo: The experiment was conducted in the Department of Animal Science of the Federal University of Lavras. The objectives were to obtain chemical, physical and sensory characteristics of pork meat receiving different levels of ractopamine in the diet, in the period of 28 days. Sixty hybrids pigs were used, being 30 castrated males and 30 females, selected for high deposition of lean meat, with initial weight of 84,27±2,26 kg. The experimental design was a completely randomized block design with six treatments (0, 3, 6, 9, 12 and 15 ppm of ractopamine) and 6 repetitions with the experimental plot represented by a male and a female. The addition of ractopamine in the diets of the pigs at the levels tested improved the chemical composition both for the loin as for the cup, contributing to greater protein deposition and a lower percentage of lipids in the cuts. In physical characteristics the highest levels of ractopamine agreed to texture and changed the color, in addition to the acceptance by consumers. Already in relation to oxidative stability, both for the loins stored under refrigeration as under freezing, the addition of ractopamine diets for pigs in the finishing phase helped in the prevention of lipid oxidation.

Foram utilizados 72 suínos híbridos, sendo 30 machos castrados e 30 fêmeas, selecionados para alta deposição de carne, com peso inicial de 84,27±2,26 kg. O delineamento experimental foi em bloco casualizado, com 6 tratamentos (0, 3, 6, 9, 12 e 15 ppm de ractopamina) e 6 repetições, com a parcela experimental representada por 1 macho e 1 fêmea. A adição de ractopamina nas dietas dos suínos nos níveis testados melhorou a composição química tanto do lombo quanto da copa, contribuindo para uma maior deposição proteica e uma menor porcen-tagem de lipídeos nos cortes. Nas características físicas os níveis mais altos de ractopamina comprometeram a textura e alteraram a cor, além da aceitação pelos consumidores. Já em relação a estabilidade oxidativa, tanto para os lombos armazenados sob resfriamento quanto sob congelamento, a adição de ractopamina as dietas de suínos em terminação auxiliou na prevenção da oxidação lipídica.Universidad de Córdoba2017-08-23T17:31:56Z2017-08-23T17:31:56Z2014-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfLEAL R.
