the presence of microbial load and high fiber content in various non conventional feedstuffs limit their utilization in poultry feed. in the present study, the feedstuffs were treated with acidified sodium chlorite (asc) and its impact on  the microbial load and metabolizable energy availability was assessed in  the chickens. the effect of supplementation of feed grade enzyme was also evaluated...

The hides of cattle are the source of Escherichia coli O157:H7 that contaminates beef carcasses during commercial beef processing. Therefore, effective interventions that reduce hide contamination should reduce subsequent carcass contamination. The first objective of this study was to identify the most effective reagents for decontamination of beef hides. Cattle hides draped over barrels were u...

We read with interest the report by Sofi et al. (1) in Diabetes. This article is of practical interest to many groups who use the nonobese diabetic (NOD) mouse model. As this group observed, we have also observed that mice that are ordered from The Jackson Laboratory tend to get diabetes sooner than those bred in National Institutes of Health facilities. The results in this article suggest this...

the use of propionate agar resulted in very low yeast counts in samples of plant material as compared to the populations obtained with acidified dextrose agar and synthetic agar. Acidified synthetic agar proved to be the medium of choice for the enumeration and isolation of yeasts from plant material. Counts obtained on this medium were comparable to those on acidified dextrose agar and mold gr...

Background: Iran is located within the dry and semi dry regions, thus almost 90% of the required water is secured via the use of groundwater. Owing to the increasing pollution of water resources, this study was performed to evaluate water quality pollution indices for heavy metals (As, Zn, Pb and Cu) contamination monitoring in Toyserkan Plain during spring and summer in 2012. Methods: A tot...
