SPATIAL VARIABILITY OF THE MICROCLIMATE IN DIFFERENT SMALL RUMINANT HOUSE LOCATED IN THE SEMIARID OF PERNAMBUCO, BRAZIL REA
Gonçalves,Indira C. M.; Turco,Sílvia H. N.; Leitão,Mário de M. Vilas Boas R.; Oliveira,Leane N.; Amorim,Danielle M..
ABSTRACT The spatial variability in meteorological conditions was evaluated in two small ruminant house with different constructive aspects, based on the variables of dry bulb temperature, relative humidity, wind speed and temperature humidity index (THI), through the generation of maps using the Kriging interpolation method. The experiment was conducted in two seasons, winter and summer, and the small ruminant house were denominated as: FNRG (facility at ground level with no ridge vent) and FWRG (facility at ground level and with ridge vent). The studied parameters were recorded by portable digital sensors, thermo-anemometers and thermo-hygrometers, with data collections at 9 am and 3 pm. With the analysis of the spatial variability of the data, it was...

Spatial variability of air temperature in a free-stall in the Northeastern semi-arid region of Brazil AGRIAMBI
Gonçalves,Indira C. M.; Turco,Silvia H. N.; Ramos,Clóvis M. C..
ABSTRACT The knowledge on the spatial variability of climatic attributes and the building of Kriging maps can assist in the design and management of confined animal facilities, by allowing a spatial visualization that is helpful for the planning and control of information from the production environment. The study aimed to characterize the spatial variability of air temperature in a free-stall barn used for dairy cattle confinement located in Petrolina-PE, Brazil, in different seasons and at different times. The variable air temperature was recorded at 136 points distributed in the areas under the shed and the shade cloth for the study of spatial variability and the construction of maps by Kriging. Air temperature data was collected in the winter and in...
