RESUMO:

Cutting coturniculture has become a highly promising activity in the country, making it necessary to search for alternatives to reduce costs, optimizing meat production together with sustainability. Some products can be used as performance enhancers, however, they can cause marketing problems if distributed in more demanding countries. An alternative would be the use of pyrolignose extract (EP), which is a product that acts as a natural performance enhancer because it contains phenolic compounds, aldehydes and ketones that have bactericidal, antifungal and antioxidant properties. In this way, the objective was to evaluate the performance and carcass yield of European quails housed in two types of bed supplemented with pyrolignous extract. The experiment was conducted using 400 shear quails from 1 to 42 days, distributed in a completely randomized design in a 5x2 factorial scheme, with five levels of pyrolignous extract (0,0, 1,0, 1,5, 2,0 and 2 , 5%) and two types of bed (new and used), totaling 10 treatments and 4 replicates, 10 birds per experimental unit, housed in pits. The birds were weighed at the beginning and at the end of the experimental period to evaluate the performance parameters (weight gain (GP), feed intake (CR) and feed conversion (CA)). At the end of the experimental period, 8 birds were slaughtered from each treatment to evaluate the carcass (carcass yield (RQ) and body weight). The economic analysis of the utilization of the extract in the ration was also evaluated through ration cost calculations, effective operating coefficient, gross revenue, gross margin of the effective operating coefficient, effective operating profit and profitability index. The supplementation levels of pyroligneous extract used in the diets did not influence (P> 0.05) the GP and CA of the birds housed in a new bed. For quails housed in bed used, a linear effect was observed for CR, GP and CA. RQ was better observed for birds housed in a new bed when compared to those housed in a used bed. As for organ weight and economic analysis, the inclusion of PE in the diet had no effect. Therefore, the inclusion of up to 2.5% of pyroligneous extract in the European quail ration housed in used litter decreased consumption without altering the weight gain, improving feed conversion. However, when housed in a new bed, they presented better carcass yield. Regarding organ weight and economic viability, no differences were found between birds housed in new beds and birds housed in used beds.
