No. of bitstreams: 1 JOHN EMERSON FERREIRA REGIS - DISSERTAÇÃO PPGEA 2008..pdf: 7356215 bytes, checksum: e9714e5a2f15594b75435e6c592f026b (MD5) Previous issue date: 2008-02 / Visa-se, com este estudo avaliar e estabelecer os índices de conforto térmico, as respostas termorreguladoras e desempenho de tourinhos Sindi e Guzerá semiconfinados, no período de julho a setembro de 2007, realizado na Estação Experimental de Alagoinha. pertencente à EMEPA-PB, no município de Alagoinha, região do Agreste Paraibano. Foram avaliadas as variáveis climáticas: temperatura do ar (TA), índice de temperatura de umidade (ITU), índice de temperatura de globo e umidade (ITGU). umidade relativa do ar (UR), temperatura de globo negro (TGN) e velocidade do vento (VV) e as variáveis fisiológicas analisadas foram: frequência respiratória (FR), temperatura retal (TR) e temperatura da pele (TP) e os índices produtivos: ganho de peso diário (GPD). ganho de peso total (GPT) e consumo de matéria seca (CMS). Utilizaram-se 16 bovinos: 8 de cada raça, e idade média de 30 ± 5 e 33 ± 3. do Sindi e Guzerá, respectivamente. Os índices ambientais foram medidos diariamente a cada duas horas (das 6 às 16 horas). Os índices de conforto ITU (77,5) e ITGU (78,6) estiveram, nos horários mais quentes, fora da zona de conforto térmico, atingindo níveis considerados críticos, mas as FR e TR se mantiveram dentro da normalidade para a espécie. O desempenho produtivo em ambas as raças permaneceu acima do esperado e as raças responderam satisfatoriamente às condições deste experimento, indicativo de uma boa resposta fisiológica. / The objective of this study was to evaluate and to establish the comfort indexes, the answers thermal regulate and acting of Sindi and Guzera semi confmed, in the period of july to september of 2007. Accomplished in the experimental station of Alagoinha. belonging EMEPA-PB, in the municipal city of Alagoinha, area of Agreste Paraibano. They were appraised the climatic variables: Temperature of the air (TA), Index of Temperature of Humidity (THI), Index of Temperature of Globe and Humidity (BGHI). Relative Humidity of the Air (RH), Temperature of Globe Black (TGN) and Air of the Wind (AW). Physiologic variables: respiratory rate (RR), Rectal Temperature (RT) and Skin Temperature (ST) and the productive indexes: Earnings of Daily (GPD) Weight. Earnings of Total (GPT) Weight and Consumption of Matter Dries (CM). 16 were used bovine: 8 of each race. With médium age of 30 ± 5 and 33 ± 3, of Sindi and Guzerá, respectively. The environmental indexes were measured daily every two hours (6 the 16 hours). The comfort indexes, THI (77,5) and BGHI (78,6). were. in the hottest schedules, out of the area of thermal comfort (ZCT), reaching leveis considered criticai, but RR and RT stayed inside of the normality for the species. The productive acting in both races was above the expected, the races answered the conditions of this experiment satisfactorily, being an indicative of good physiologic answer.
