Effect of Asparagus racemosus, Sida cordifolia and Levamisole on immunological parameters in broilers

In recent years frequent outbreaks of poultry diseases have caused significant economic losses, resulting in set back to poultry production. There are several causes including poor quality of inputs such as stocks, feeds and drugs, other contributory factors Viz., management lapses and medication. The end result is the disturbance in birds natural immunity. There are certain medicinal plants, which have immunomodulatory effect. Indigenous plant like Asparagus racemosus playing a role of immunomodulation (Seena et al., 1993) as well as medicinal plant like Sida cordifolia have immune enhancing properties (Dixit et al., 1978), similarly Levamisole is a well known immunomodulatory drug which enhance cellular and humoral immune response. However, information about effect of plant likes Asparagus racemosus, Sida cordifolia and Levamisole in relation to immunological change in immunosuppressed birds is not adequately available. Therefore, present study was undertaken.
