502			_aThis study indicated that live Mycoplasma gallisepticurn vaccine when administered to the chickens vaccinated with Newcastle vaccination had immunosuppressive effects. Live Mycoplasma gallisepticum vaccine partially interfered with the development of serum antibodies against NDV in vaccinated chickens. However, when live MG vaccine is done alone in the chickens it gives good serum antibody titres. rube injection to baby chicks on first 4 consecutive post hatching days with cyclophosphaniide resulted in lower body weights, poor FCR, destruction of the bursa of fabricius, poor antibody response of birds to vaccinations against MG and ND. The weight gain and FCR studies. indicated that the birds which were vaccinated either against live MG or NDV had significantly higher body weights and FCR values than those vaccinated both against MG and NDV. These studies further indicate that the birds vaccinated against live MG and ND had significantly lower serum antibody titres on day 48 than the birds which were vaccinated against either live MG or NDV. From the results of this study it was concluded that F-strain MG vaccination effective the growth performance and feed conversion efficacy of broiler chicks. The live MG vaccination also interfered in the development of immune response (antibody titers) against Newcastle disease virus.
