Abstract:
One trial was conducted to study the microbial load or the microbiological
composition of litter (red wood shavings and Rice crust), prior to placing 1-d-old
chicks, and after depopulation, the microbiological composition were as
following Bacillus, Staph., Strept., Salmonella, G+ rods, Enterococcus,
Clostridium, E. coli, Lactobacillus ,Coliform, the total aerobic plate count (APC)
was determined and the predominant microflora of the samples was identified as
possible.
Before chick placement, the APC of wood shavings (about 1.02 log10/g) was
lower than the APC of Rice crust (about log10 1.47/g) of G+),with stocking, in
both types of litter the bact. contamination increased to about (5.68 log10 of G+)
and(6.76 log10 /g of G+),respectively, no isolation of any G- bacteria before
chicks placing from red wood shaving, while the count of G- bacteria was equal
to log10 0.69/g in the ice crust litter, and(about log10 4.02 of G- and 4.95 log10 /g
of G-), before and after depopulation, respectively with significant differences
between two kinds of litter also before placing chicks and after depopulation.
