Abstract

An experiment was conducted to assess the level of mould contamination in the air of sheep pen and its influence on growth performance of lambs on slatted floor and mud floor. Weekly measurements were taken at 8 am and 2 pm for the estimation of mould count in air and climatic variables viz. air temperature, relative humidity and air velocity. The body weights of lambs were recorded fortnightly . Total mould count was significantly (P<0.01) higher in mud floor pen (22.94 ± 1.40 cfu per 30 l of air) than in slatted floor (15.08 ± 1.12 cfu per 30 l of air), whereas the type of floor had no effect on climatic variables. The body weight (24.23 ± 1.27kg) of lambs were significantly (P<0.01) higher in slatted floor.
