RESUMO:

Cutting coturniculture has become a highly promising activity in the country and it is important to seek alternatives to reduce costs by optimizing meat production together with sustainability. Thus the pyrolignous extract is a product resulting from the condensation of the smoke expelled during the wood burning in the production of charcoal, containing more than 200 chemical components. The objective of this study was to evaluate the levels of pyroligneous extract as an additive in the diet on performance and carcass yield of European quails housed in different types of litter. The experiment was conducted using 400 cut quails (Coturnix coturnix coturnix), 1 day for 42 days, distributed in a completely randomized design in a 5x2 factorial scheme (five levels of pyroligneous extract and two types of litter: new and reused), totaling 10 treatments and four replicates, ten birds per experimental unit, housed in pits. The treatments corresponded to levels of pyroligneous extract 0; 1,0; 1.5; 2.0 and 2.5%. At 42 days of age, weight gain, feed intake and feed conversion were evaluated. For carcass yield, 80 birds were slaughtered for evaluation of the carcass yield, hot, cold, weight and yield of the organs. There was no significant effect of any source of variation (firefly and poultry litter levels) on the initial weight, final weight and weight gain (GP) of the birds kept on the new bed. However, there was a linear effect (P <0.05) of the firefly levels on the GP of the birds kept on the reused bed (CRT). However, there was an interaction effect between the firefly and the poultry litter on the birds' GP in the CRT. Feed intake (CR) and feed conversion (AC) also had an interaction effect for both sources of variation (CNV and CRT). There was no significant effect (P <0.05) for the carcass yield characteristics nor the interaction effect of the firefly and poultry litter. Therefore, the pyroligneous extract can be added to feed as an additive at the 2.5% level without changing the performance characteristics and carcass yield. It also showed efficacy in reused bedding.
