Abstract
A study was conducted to assess the viability of spray dried probiotics in
crumble feed during storage. The Bacillus subtilis (T1), Bacillus
amyloliquefaciens (T2), Bacillus coagulans (T3), Bacillus clausii (T4),
Lactobacillus acidophilus (T5) and Bifidobacterium bifidum (T6) cultures
were propagated using skim milk and spray dried by using spray drier. The
spray dried probiotic powder was diluted with water and sprayed on broiler
crumble feed. After spraying, crumble feed was stored in room temperature
(25-33°C) for 0,7 and 14 days and the viability of probiotics was assessed
before and after spray drying and during storage with crumble feed. B.
clausii showed better yield after spray drying while B. subtilis showed
highest survival rate (83%) among all probiotics studied. At the end of 14
days of storage, the survival rate was maximum in B. amyloliquefaciens
among spore forming probiotics (95.61%) and among non-spore forming
probiotics the B. bifidum (85.24%) evinced better survival.
