| ABSTRACT The current study aimed to evaluate the influence of three colors and two types of roofing materials under the internal temperature of bee colonies Apis mellifera. The experiment was conducted at the Agricultural Sciences Campus at the Federal University of Sao Francisco Valley located in Petrolina-PE, in November and December 2013, using 24 colonies housed in Langstroth hives. The experiment was a completely randomized factorial design (3x2) with three colors of box (blue, white, and traditional) and two types of cover (with and without the use of plaster) with six treatments and four replications. The internal temperature dates of the colonies were hourly recorded, during 24 hours, and surface temperatures were hourly recorded between 08h00 and... |

| Abstract The electronic monitoring of physiological responses is essential for managing animal production systems considering market demands for animal welfare. The objective of this study was to design, build, and test an electronic monitoring system, with recording and wireless transmission capability, for measuring the heart rate and skin temperature in small ruminants. The system had two components: a mobile base unit, mounted on the animal under study, and a fixed base unit. Wireless communication between the mobile and fixed units was performed using a Xbee Series 2 radio frequency transceiver whereas data were recorded and transferred to a secure digital card in the mobile unit. The device was mounted in Santa Inês crossbred sheep using reference... |
