Abstract
A comparative study was undertaken to evaluate the effect of supplementing spore probiotics in pre-pellet or non-spore conventional probiotics in post-pellet feed on the performance of broiler chicken to assess whether non-spore probiotics adequately perform.
Four spore forming B. subtilis (BS, NCDC 70), B. amyloliquefaciens (BA, ATCC 23842), B. coagulans (BC, ATCC 7050), and B. clausii (BCL, BCL 2B) and two non spore forming L. acidophilus (LA, NCDC 15) and B. bifidum (BB, HI 48) probiotics were procured and experimented. BC showed highest recovery (38 %) followed by BS (36 %), BC (33 %), BA (31 %), LA (30 %) and BB (29 %) after spray-drying.
Addition in crumble feed and stored for 0, 7 and 14 days at room temperature, BA (8.88 to 8.49 log10 cfu/ml, 4.39 %) and BB (6.03 to 5.14 log10 cfu/ml, 14.76 %) survived better on day 14.
