Résumé partiel
The present investigation was carried out to study the effect of improved shelter management practices on performance of lactating Sahiwal cattle in arid region of Rajasthan. A total of 24 apparently healthy Sahiwal cow in their early lactation period (1-3 months) selected from Livestock Research Station were randomly assigned to four groups. One group-1(G-1) acted as control without any shelter management reared on pucca floor made up of cement concrete blocks in covered area. The experimental cows in group-2 (G-2) were reared on rubber mat bedding over pucca floor in covered area. In group-3 (G-3) were reared on pucca floor (made up of cement concrete blocks) in covered area with physical modification in shelter. In group-4 (G-4) were reared on rubber mat on floor in covered area with physical modification in shelter. Physical modification by providing fan and splashing of water on the body for two times a day at 11.00 AM and 3.00 PM daily of cattle reared under different groups. Performance of Sahiwal cattle was assessed by studying the physiology, milk yield and quality, haematobiochemical, reproductive, health and behavior parameters. The obtained results of meteorological variables indicated that there was wide variation in temperature and THI. With respect to main effect of shelter management, there was observed significant changes in respiration rate, rectal temperature and pulse rate. Rectal temperature, was significantly (P<0.05) lower in G-3 and G-4 group as compared to other groups of Cattle. Respiration rate was significantly (P<0.05) lower in G-4 group as compared to other groups of Cattle whereas, pulse rate was significantly higher (P<0.05) in G-1 and G-2 groups as compared to other groups. The overall mean daily milk yield of cow was significantly (P<0.05) higher in physically modified Shed (G-3 and G-4) as compared to other shed (G-1 and G-2) during Experimental Period. This might be due to provision of fans with splashing of water in 152 respective groups.
