Abstract:

A study was carried out to assess the impact of shelter designs on the production performance of dairy cattle in the three selected agro – climatic zones of Tamil Nadu. viz., Southern, Cauvery delta and High rainfall zones. The effect of various shelter designs on the activity of liver enzymes and stress hormones were analyzed. The serum samples were collected throughout the year i.e. in all the four seasons, viz., winter, summer, south-west monsoon and north-east monsoon. For each season, a total of thirty samples (in duplicate) were collected from five housing types each comprising of six individual cattle from the three agro-climatic regions for measuring the bio-chemical profile. The activity of the four serum enzymes, namely AST, ALT, ChE and LDH were estimated spectrophotometrically and the three stress hormones namely cortisol, T3 and T4 were estimated by ELISA. The levels of AST, ALT, CHE and LDH differed significantly (P<0.01) between seasons in all the zones, Similarly a significant difference (P<0.01) in the concentration of cortisol, T3 and T4 was also observed between seasons in all the zones, whereas significant difference in T4 levels was observed between housing types in Southern zone only. Factor analysis study of this biochemical profile with other climatic, physiological and production parameters in all the three zones revealed that in Southern and Cauvery delta zones open housing is best and in High rainfall zone thatched roof system is the best.
