Description The effect of grainless/low grain diet on immune response was studied by taking 5 month-old male crossbred calves (25). The calves were divided in 5 groups, viz. SI ,S2,S3,02 and 03 of 5 calves in each group where calves in group SI (control) received a conventional maize grain based concentrate mixture. The maize moiety was replaced by 50% in groups S2 and 02 and by 100% in 83 and 03. Calves in groups SI , S2 and S3 were offeree!ad lib. wheat straw and those in groups 02 and 03 were offered green sorghum fodder ad lib. from 20 week of age. At 26 weeks bfage, all the calves were vaccinated with Pasteurella multocida (P-52 strain) and blood was collected at 0,7,14 and 28 days of postvaccination period. Both cellular and humoral immune responses were observed. All cellular componetlts (TLC and DLC) were found in normal range in all the groups during post vaccination periods. The antibody level of zero day was not detected by STAT (standard tube agglutination test) but could be detected by ELISA (enzyme linked immunosorbent assay)indicating presence ofmaternaJ antibody. The antibody level as detected by STAT and ELlSA during post vaccination periods (7,14 and 28 days) showed a rise from 7th day onward and continued to increase up to 28th day. The albumin : globulin ratio (A:G ratio) increased in post vaccination periods. Study indicated the partial or complete replacement of cereal grain with wheat bran had no significant effect on the immunity of crossbred calves.
