O Semiárido brasileiro corresponde a aproximadamente 60% da Região Nordeste e ocupa uma área de 969.589,4 km2. Está inserido em todos os estados nordestinos e parte do norte de Minas Gerais (BRASIL, 2005). No Semiárido, a maioria dos produtores explora uma agricultura em condições de dependência de chuvas que, por causa da irregularidade pluviométrica, sofrem perdas de safra em culturas de subsistência. A baixa produtividade pode estar relacionada ao não uso de tecnologia de captação de água de chuva, como também ao manejo inadequado do solo e da água, pouca cobertura do solo e à adubação, principalmente orgânica, já que se trata de agricultura de base familiar. |

Integrated agricultural production systems seek to optimize the use of land resources, increase meat production and diversify production, adding an arboreal component to already cultivated areas, contributing to the system by improving animal welfare and providing other outputs, such as wood. The objective was to evaluate microclimate and steers behavior in integrated systems. The experiment was carried out in Sinop, MT. Treatments consisted of three systems: livestock (L) with Marandu palisadegrass, crop-livestock (CL) with soybean and maize + Marandu palisadegrass and livestock-forest (LF) with triple rows of eucalyptus and Marandu palisadegrass, during a dry-rainy transition period and a rainy season. The design was a randomized block with four replicates, each in a paddock of two hectares. Nellore steers were used with an average initial weight of 344 ± 11 kg in continuous grazing with variable stocking rate. The microclimate was evaluated using sensors connected to data loggers in each paddock. Temperature and humidity index (THI), black globe temperature and humidity (BGTI) and radiant heat load (RHL) were calculated. Animal behavior was evaluated with direct observation every 10 minutes from 07:00 am to 05:00 pm. Data was analyzed using a SAS mixed model. The highest indexes were obtained in the dry-rainy transition season from 11:00 am to 03:00 pm. THI and BGTI were the same for all systems during the dry-rainy transition period (83). For the rainy season the averages were 79 for THI and 85 for BGTI for L and CL, while 81 and 86, respectively, for the LF. During this same season, the THI and BGTI were, respectively, 83 and 89 under direct sunlight and 80 and 84 in the shade. The RHL in the dry-rainy transition season was 644 Wm-2 for L and CL and only 606 Wm-2 for LF. In the rainy season it was 654 Wm-2 for L and CL and 608 Wm-2 for LF. During this same season, the FP system presented an average of 650 Wm-2 under direct sunlight, reaching a pick of 728 Wm-2, while in the shade, the average, was 560 Wm-2, with a maximum of 596 Wm-2. The longest grazing period was recorded from 9:00 am to 1:00 pm and after 3:00 pm, regardless of the system. Rumination occurred more frequently during the rainy season on the LF, in the shade from 1:00 pm to 3:00 pm. LF systems where grazing areas presented shading opportunities may improves animal welfare due to lower thermal indices.
