  Coccidiosis is the most important parasitic infection in poultry worldwide. Control is largely limited to good husbandry and prophylactic chemotherapy using a range of drugs against which resistance is rapidly acquired. Attempts at vaccination using conventional vaccines have been disappointing and there is now a need for new approach. These include biology of parasite to identify the life cycle stages that are vulnerable to immune attack; antigenic characterization, heterogenicity; variability; and effector mechanisms responsibility for immunity. The purpose of this review is to update/summarize the recent advances in the development of vaccines against the avian coccidiosis.

  Pot experiments were conducted to compare DCP, an industrial bye-product, against standard fertilizer SSP for growth and P uptake behaviour and to evaluate the performance of DCP as a P fertilizer source for several crop species. Single superphosphate and DCP were applied @ 0, 22, 44, 88, and 176 mg P kg -1 to a loam soil (Lyallpur III series, typic ustocrept). The first crop series grown were wheat, lentil and chickpea while the second series contained sorghum, maize and mungbean and in third series bermuda grass, brassica and berseeem were used. After each crop harvest soil samples were drawn for P analysis and the same P rates from two sources were applied to respective pots. Plants were grown for various time periods before harvesting and P uptake was estimated. Rate of P application increased DMY and P uptake, but the P rate required for maximum DMY varied depending on crop requirements. Brassica, bermuda grass and mungbean were less responsive to applied P while berseem, maize and sorghum responded more to P application. The behaviour of the two sources for DMY and P uptake by the six crop species were mostly alike. However, for crops that responded more to P application, DCP proved similar or sometimes superior to SSP. The amount of residual P after each crop harvest was significantly higher in DCP as compared to SSP applied treatment.
