A comparission study of locally probiotic with imported probiotic in microbial balance of broiler gastro-intestinal tract

Abstract

This study aimed the effect of adding 0.5 and 1 kg of imported probiotic
/ton feed (T1 and T2) compared with the a percentages of 1.5, 3 kg locally
probiotic / ton (T3 and T4) when as T5 used feed free of probiotic .500 dayold
chicks were distributed into five treatments and subdivided into two replicates
(50 chicks per replicate) to study the effect of adding the two probiotics in the
microbial balance of broiler gasto-intestinal tract .The results obtained revealed
the following:-
Adding percentages of locally or imported probiotic (T1, T2, T3 andT4)
decreased significantly (P<0.01) log no.of Coliform count and fungi count at
mid point of intestine (Jejunum), crop and cecum of broiler, at the same time
Adding the two probiotics increased significantly (P<0.01) log no.of
Lactobacilli count compared with control group (T5) .Whenas significant
differences in the log no. of total bacterial count at mid point of intestine and
crop. Also no significant differences between locally or imported probiotic were
noticed in the studied microbial counts or to the adding percentages. Conclosion
is the importance of adding probiotics to the feed for optimum microbial balance
to increase resistance of broiler to pathogenic bacteria.
