Abstract:

Calves are important assets of the poor dairy farmers as they play a major role in uplifting their socio-economic condition. Calfhood diseases are the major cause of economic losses in livestock, one of the most important being respiratory affections. The present work was conducted to investigate the bacterial entities responsible for respiratory affections in bovine calves in Palampur Valley of Himachal Pradesh, India. Samples were collected asceptically from the nasal cavity using sterile nasal swabs from 51 sick and apparently healthy animals from Palampur and its surrounding districts. Standard microbiological techniques were used for isolation and identification of bacterial isolates. In between the sampling period eleven calves showing moderate to severe respiratory signs succumbed and the necropsy examination revealed lesions of pneumonia in all eleven cases. From a total of 51 samples, 46 yielded bacterial isolates with two cases showing mixed infection, hence a total of 48 isolates were obtained. The common isolates obtained from the nasal passages were E. coli (45.83%), Streptococcus. sp (27.08%), Staphylococcus. sp (14.58%), Citrobacter. sp (12.5%). Screening of nasal bacterial flora from the sick animals was done in order to determine the prevalence and to provide better treatment to further sustain animal life.
