The aim of this study was to establish radioimmunoassay (RIA) for fecal estrone sulfate (E1S) and to elucidate changes in fecal E1S during pregnancy in the sow. Fecal E1S was extracted on a commercially available solid phase column, and the E1S fraction obtained was subjected to RIA. The sensitivity of the RIA was 8.5 pg/tube. The intra- and inter-assay coefficients of variation were 8.8-8.9% a...

Cats are important in the epidemiology of Toxoplasma gondii because they are the only hosts that excrete environmentally resistant oocysts in feces. In the present study, hearts, serum, and feces from 36 feral cats from Addis Ababa area, Ethiopia, were examined for T. gondii infection. Antibodies to T. gondii were determined with the modified agglutination test (MAT, cutoff 1:25); 33 cats were ...

When studying digestibility, the respective parts of the exogenous, endogenous and bacterial fractions in the digesta or feces must be measured. The proportions of proteins from different sources may be estimated by comparing their amino acid composition with those of reference sources. This study describes the composition of endogenous and microbial proteins, i.e. meconium of piglet small inte...

Antibiotic feed supplements have been implicated in the rise of multidrug-resistant bacteria. An alternative to antibiotics is probiotics. Here, we report the genome sequences of two Bacillus and one Solibacillus species, all spore-forming, Gram-positive bacteria, isolated from the feces organically raised chicken feces, with potential to serve as probiotics.

Methods 1. Determination of Free and Esterified Vitamin A in Blood Plasma The Fujita method (1) using alumina chromatography for separating vita min A alcohol from esterified form and measuring photometrically with the glycerol dichlorohydrin method, was employed. 2. Determination of Vitamin A Content of Feces The improved method of Fujita (2) for eliminating non-vitamin A sub stances in feces,...

Background & Aims: Probiotic bacteria have beneficial effects on host's health. However, one of the most important reasons which affect the probiotic activity of a microorganism is its survival during the gut transit. Microencapsulation techniques could be applied to bacteria to improve this parameter. Methods: In this study, feces of 60 healthy volunteers were analyzed during 28-day test perio...

Intestinal parasites of swine are still present under conditions of modern swine management and can have a significant impact on growth rate and feed efficiency. Diagnosis of intestinal parasites can be accomplished by demonstrating adult parasites in feces or at necropsy, and by demonstrating eggs in feces. This article details a protocol for sampling fecal material to diagnose intestinal para...

this study was done to investigate the nutritive value of festocaovina, agrostisgiganta and avena sativa using sheep rumen and feces liquor as sources of micro-organism through gas production method. rumen and feces liquor were collected from three fistulated sheep. rangeland species sampling was randomly conducted from different areas of guilan province. all the collected samples were initiall...
