Abstract
Aim: To find out the influence of different types of roofing materials
on micro-climate in animal loose housing system during rainy season.
Materials and Methods: Different shade materials were used for covered
area under each of three treatments. Thatch shading roof (T1), Agro-net
shading roof (T2), Asbestos with canvas shading roof (T3). Long axis of the
paddock was east-to-west orientation. The covered area floor space was 1.5 ×1
m (excluding manger) for each animal and open paddock was 2 × 1 m. Height of
shed at eaves was 2 meter. Daily temperature (maximum and minimum) and dry
bulb and wet bulb temperature of macro and micro- environment under different
treatments were recorded at 9:30 AM and 2:00 PM of Indian Standard Time (IST)
by using maximum and minimum thermometer and dry and wet bulb thermometer.
Both inside and outside surface temperatures of shade materials were measured
by infrared digital thermometer (ebro, TFI 220). The statistical procedures
followed were two way ANOVA and Paired 'T' test.
Results: During the
experimental period, maximum temperature was recorded under asbestos and
lowest temperature was in agro-net and maximum protection from high
temperature was given during peak hot hours in agro-net than asbestos. THI was
more (P<0.05) under asbestos than agro-net and thatch.The outside surface
temperature at 9.30 AM and 2:00 PM (IST) was significantly lower (P<0.05) in
agro-net than thatch and asbestos.
Conclusion: Thatch and agro-net were
better in warding off the hot and humid environmental condition in comparison
to asbestos.
