SUMMARY:

The aim of this study was to evaluate the effect of different levels of pyroligneous extract (EP) inclusion on performance, carcass characteristics, meat quality and diarrhea index in the pig diet in the growing and finishing phases. Twenty-four crossbred females with an initial average weight of 31.2 kg were used. The animals received food and water ad libitum. The diet was composed of corn, soybean meal, vegetable oil and commercial kernel and the treatments consisted of increasing levels of inclusion of pyroligneous extract in the diets (0; 0.5; 1.0 and 1.5%). At the end of the experimental period, the performance parameters (daily weight gain, daily feed intake and feed conversion) were evaluated; Carcass quantitative and qualitative parameters (Carcass length, Bacon thickness, Hot carcass weight, Chilled carcass weight, Shank weight, Carcass yield, Cooling weight loss, Loin depth, Loin eye area, fat and meat ratio: fat, pH, temperature, marbling and muscle color). The results showed that there was no significant difference in the growth phase between treatments, however, the animals that received 1.5% of EP in the finishing phase had higher feed intake and greater daily weight gain. There was no difference between quantitative and qualitative carcass parameters, except for the pH measured at 45 minutes after slaughter, which was higher in animals that received 1.5% of dietary EP, however, these values stabilized and showed no difference when measured 24 hours after slaughter. The evaluation of the diarrhea index showed that the PE did not change the feces of the animals. It is recommended to use 1.5% of EP in the finishing pig diet.
