This research was carried out to evaluate the sufficiency of existing ventilation and lighting systems of the water buffalo barns in Thrace region of Turkey with regard to animal welfare. As a result of this research, it was found that 61.3% of the barns had a ventilation chimneys, total cross-sectional areas of the ventilation chimneys varied among the barns and ranged from 0.25 to 5.2 m 2. Based on animal welfare, this value should be between 0.45 and 11.8 m 2 according to barn capacity. The

The window areas for natural lighting had great difference among the barns and the percentages of window area depending on barn floor area were calculated between 0.66 and 4.80%. When the region's climatic characteristics and animal welfare are taken into consideration, this value should be at least 7.5% of the barn floor area. 94 % of the barns had artificial lighting but the artificial lighting values per unit floor area (1 m 2) were found between 0.2-2.3 W. This value should be in the range of 4-6 W / m 2. Introduction The main objective in commercial animal breeding is to obtain the highest economical efficiency. This may be possible with sufficient feeding, proper genotype and balanced environment conditions of animal barns [1]. Planning and construction of barns should be taken care because housed animals are expensive and obtained products are closely related to human health. Despite the genetics and physiological characteristics of water buffaloes are different from other cattle in our country, they are considered in the same category. Thus, there have not been enough scientific studies on the control of climate environment in water buffalo barns. One of the most important factors in effective utilization of the genotypic potential is to maintain optimal indoor climatic environmental conditions. The outdoor thermal conditions are generally incompatible with optimum thermal conditions for farm animals. In order to provide proper thermal conditions for animal welfare, some environmental variables such as temperature and humidity should be controlled. It is possible to keep temperature and humidity at desired values for different seasons with well-planned ventilation systems for water buffalo barns. In order to enable effective ventilation systems, the air inlet and outlet openings which can provide air exchange within the structure and have a certain height difference between them, must be well planned. On the other hand, artificial and natural lighting systems should be sufficient in terms of animal health and hygienic conditions. This study was conducted in order to investigate sufficiency of the climatic control units for the water buffalo barns located in Thrace part of Turkey.
