An instrument was designed and standardized for determining the tracheal mucus clearance rates in chickens. Dosages for E. coli and NDV infections were standardized. Day old broiler chicks were divided into two groups, one group was fed Mulhatti root powder @ 2g/kg body weight supplemented in feed. At two weeks of age these birds were further divided into 4 subgroups each and infected with E. coli, NDV and E. coli + NDV. Uninfected controls were also kept. The birds were sacrificed at different sampling intervals and the tracheae thus collected were subjected to mucosal transport measurements. The study revealed that the infection with E. coli and NDV casued a drop in tracheal mucus clearance rates and feeding of Mulhatti root powder did not provide any added advantage to the chicks in recovery rates from the depression in tracheal mucus clearance. The study being first of its kind, it is suggested that the experiment be repeated on a larger population.HindiThesis
