  The aim of this research has been to determine the effect compound of probiotics, lactase enzyme and antibodies on improving the histomorphology characters of lymphoid organs and improving growth humoral immunity of broiler chickens. For this purpose, 96 broilers (W- Ross 308) have been randomly divided into two groups of 48 with 4 replicates. For  evaluation of  humoral  immunity,  samples  were  selected  from  each  replication  randomly at 3rd, 23th and 42th day of production, and cc blood  was  got  from  wing  vein  and  HI  was  tested. For evaluation of histomorphology of lymphoid organs at the end of period, randomly two slaughter samples were selected from each replication has been sent to the histology lab. The  results  of  statistical  analysis were shown  that  rate of antibodies was  non significant at  -day – old  (p>0.05) and  it was  significant  at days  and  days (p). Microscopic studies of lymphoid organs (Bursa of fabricius, spleen and thymus) were shown significant statistical difference (p<0.05) but non significant at other parameters. According to the results of using of the combination can improved humoral immune system and has no medicinal residue in   poultry meat, it can be an appropriate substitute for growth stimulating antibiotics.
