Lack of response by growing-finishing pigs to germicidal ultraviolet radiation
Published online by Cambridge University Press: 27 March 2009
Extract
Three tests—two winter and one summer—involving 134 growing-finishing pigs showed no response to germicidal ultraviolet radiation. The pigs received no direct sunlight and were irradiated nearly continuously for periods of 54–70 days. Lamps with a 2537 Å output of 5·2 W were provided at rates of one lamp per 11·1 m2 in two tests and one lamp per 3·35 m2 in one test.
