Season had highly significant (P<0.01) effect, while roof and season x roof interaction did not have significant (P>0.05) effect on the maximum temperature, while roof had significant (P<0.05) and season had highly significant (P<0.01) effect, while season x roof interaction did not have any significant (P>0.05) effect on the average minimum temperature in the present study. In case of relative humidity roof had significant (P<0.05) and season had highly significant (P<0.01) effect, season x roof interaction did not show significant (P>0.05) effect. The average daily feed, (green, dry and concentrates) consumption differ significantly (P<0.01) among seasons while roof and seasons x roof interaction did not reveal any significant (P>0.05) effect. In case of milk production, season showed highly significant (P<0.01) effect on the milk yield of the cows while roof and season x roof interaction did not influence the trait significantly (P>0.05).<#LINE#>Bhagwat A.L.@Low cost housing designs and structures to suit tropical and sub- tropical conditions Proceedings@XXth World’s Poultry Congress, New Delhi, II, 621-630 (1996)@Yes$Chalkey J.N@Thermal environment of the student of architecture@The Architectural Press, London, 23-32 (1968)@Yes$Saikia P.@Effect of different roofing materials and stocking densities on the performances of broilers M.V.Sc thesis@A.A.U., Khanapara, Guwahati, 22 (2001)@No$Yadav J.L.@Effect of different housing systems on the performance of lactating buffaloes during summer@M.V.Sc.
