| Resumo: | The objective was to evaluate the carcass characteristics and meat quality of castrated male pigs, supplemented in the finishing phase with different levels of pyroligneous extract in the diet. Twenty-four animals were used, distributed in 4 treatments with 6 repetitions. The animals were fed rations containing 0, 1, 2, and 3% of the pyroligneous extract. When the pigs reached 96.8 ± 2.6 kg they were submitted to humane slaughter and the carcasses were evaluated for final weight, hot carcass weight, cold carcass weight, the thickness of back fat, length, shank weight, loin eye area, and fat area. The parameters of color, pH, temperature, and
marbling were evaluated to analyze the quality of the pork. The results of the present study showed a statistically significant quadratic effect for the following variables: fat thickness at the last rib and temperature measured 45 min after slaughter, in which the inclusion of 0.76% of pyroligneous extract in the diet conferred lower fat thickness and the addition of 1.87% showed the higher temperature at 45 min post-mortem.
For the other measurements, no statistical difference was presented. Thus, the inclusion of pyroligneous extract in pigs' diet in the finishing phase caused an increase in the fat content of the carcass. |
