A atividade não agrícola é uma estratégia capaz de melhorar o nível de qualidade de vida no campo e retomar a idéia do desenvolvimento rural. Por outro lado, a crescente preocupação mundial com a questão ambiental e o aumento no número de pessoas que desejam realizar atividades junto à natureza favorecem a criação de programas de turisnmo rural e de educação ambiental em unidades de produção agroecológicas, desde que bem construídos. Criando mercados locais e diferenciados, o agro-ecoturismo estimula a consciência ambiental, a inclusão social e o desenvolvimento local, elevando a renda no meio rural e preservando a natureza. |

The objective of this study was to determine the equation parameters of carbon (i.e., C) flow curves and to estimate C flow and carbon dioxide (i.e., CO2) emissions from the production of 1- to 49-dayold broilers from different genetic strains. In total, 384 1-day-old chicks were used, distributed into 4 groups: high-performance males (Cobb-M) and females (Cobb- F), and intermediate-performance males (C44-M) and females (C44-F), with 6 replicates/treatment according to a completely randomized study design. Carbon intake and retention were calculated based on diet and body C composition, and expired C was stoichiometrically estimated as digestible C intake − C retention − C in the urine. Litter C emission was estimated as initial litter C + C in the excreta − final litter C. Carbon flow curves were determined fitting data by nonlinear regression using the Gompertz function. Expired CO2 was calculated based on expired C. The applied nonlinear model presented goodness-of-fit for all responses (R2 > 0.99). Carbon dioxide production was highly correlated with growth rate. At 42 d age, CO2 expiration (g/bird) was 3,384.4 for Cobb-M, 2,947.9 for Cobb-F, 2,512.5 for C44-M, and 2185.1 for C44-F. Age also significantly affected CO2 production: to achieve 2.0 kg BW, CO2 expiration (g/bird) was 1,794.3 for Cobb-M, 2,016.5 for Cobb-F, 2617.7 for C44-M, and 3,092.3 for C44-F. The obtained equations present high predictability to estimate individual CO2 emissions in strains of Cobb and C44 broilers of any weight, or age, reared between 1 and 49 d age.
