Prevalence of Theileria annulata on the Basis of Managemental Practices of the Crossbred Cows

Theileriosis is the major protozoon disease which can kills young animals & reduces the growth & production of infected animals. Looking to this aspects a study was conducted to evaluated the effect of managemental practices of crossbreed cow on disease prevalence. The prevalence of T. annulata on the basis of nutritional status of the animals was found to be highest in animals having poor nutritional status and lowest prevalence was found in animals having good nutritional status. The prevalence recorded on the basis of nutritional status of animals as inquired by owner have shown that calves up to 1 year of age having good nutritional status have prevalence of 14.81 per cent. Calves having fair nutritional status have prevalence of 40.74 per cent. The highest prevalence 44.44 per cent was recorded in calves having poor nutritional status.The prevalence of T. annulata in heifers 1 to 3 years having good nutritional status have prevalence of 20.00 per cent. Heifers that have fair nutritional status have prevalence of 33.33 per cent. The highest prevalence 46.66 per cent was recorded in heifers having poor nutritional status. The prevalence of T. annulata infections in animals up to 1 year reared in Pakka house was 18.51 per cent in kaccha house prevalence was 44.44 per cent and the prevalence of disease in open housing system was 37.03 per cent. The prevalence of T. annulata infection in heifers 1 to 3 years reared in pakka house was 20.00 per cent heifer reared in kaccha house had prevalence of 53.33 per cent and the prevalence of disease in open housing system was 26.66 per cent. The prevalence of T. annulata infection in adult more than 3 years reared in pakka house was 23.07 per cent. Adult reared in Kaccha house had prevalence of 46.15 per cent and the prevalence of disease in open housing system was 30.76 per cent. Hygiene is very important factor in dairy industry especially in disease prevalence and management hygiene play very important role in respect of disease flare up situation. The prevalence of T. annualata infection in calves up to 1 year reared under good hygienic condition was 11.11 per cent in fair hygienic condition prevalence was 37.03 per cent. The prevalence of disease was highest 51.85 per cent in calves reared under poor hygienic condition.
