Substitution of sugar cane bagasse in the chicken diet and immune response

Total proteins and protein electrophoresis were made in the sera of broiler chicken (Arber Acres) to evaluate the effect of substitution of basal diet for 4 weeks by either 8% sugar cane bagasse +2% wheat germ or 16% sugar cane bagasse +4% wheat germ whether untreated or incubated with rumen liquor for 72 h and then sterilized with 2 Mrad gamma-irradiation (treated). Both levels of untreated sugar can bagasse (8 and 16%) showed significant decrease in gamma globulins but this decrease had no effect on broiler chicken (45 days) while there was significant increase in total proteins in treated sugar cane bagasse 8% with concomitant increase in alpha 2, beta 1, beta 2 and gamma globulins. These results denoted that addition of rumen liquor to 8% sugar cane bagasse diet have resulted in an improvement in the transportation of micro nutrients and immune response most probably due to its high content of microorganisms constituting high quality animal protein; also more vaccines were recommended in feeding of chicken with sugar cane bagasse for a longer period e.g. laying hens to overcome its suppressive effect on the gamma globulins.
