Aim: To evaluate the effect of different levels of High Bentonite on growth performance, organ weight and serum biochemistry in broiler fed on diets containing aflatoxin. Materials and Methods: A total of 360 day-old commercial broiler chicks were divided at random into 8 dietary treatment groups of 42 chicks each having 3 replicates. Dietary levels of aflatoxin (0.5 ppm) and High-grade bentoni...
Balish, Edward (Syracuse University, Syracuse, N.Y.), and A. W. Phillips. Growth and virulence of Candida albicans after oral inoculation in the chick with a monoflora of either Escherichia coli or Streptococcus faecalis. J. Bacteriol. 91:1744-1749. 1966.-Bacterial protection against intestinal infection by Candida albicans was investigated in chicks with a monoflora of either Escherichia coli ...
s of papers 35 142 Citric acid improves phytate phosphorus utilization in two breeds of chicks fed a corn-soybean meal diet. K. A. Rafacz*, C. Martinez, J. L. Snow, D. H. Baker, and C. M. Parsons, University of Illinois. Previous research in our laboratory has shown that citric acid improves phytate phosphorus utilization in crossbred chicks (New Hampshire x Columbian) fed a P-deficient corn-so...
Fumonisin B1 (FB1) is a mycotoxin produced by Fusarium spp. It has been reported to be a potential cause of liver cancer in rats and esophageal cancer in humans. The underlying mechanisms of FB1 toxicity are thought to be related to the inhibition of ceramide synthase, causing an accumulation of sphingosine (SO) and sphinganine (SA), which in turn may cause tissue functional impairment and the ...
Effect of supplemental phytase on phosphorus and protein utilization and performance of broiler chickens fed on eight different wheat varieties were evaluated. The phytate contents of wheat varieties were determined. In a completely randomized design with a 8*3 factorial arrangement, 384 day-old commercial male brioler chicks (HubbardPeterson) were divided into 96 groups, four chicks per group...
Two experiments were conducted to evaluate the effect of supplemental Gln on growth performance, development of the gastrointestinal tract, and humoral immune response of broilers. Immediately after hatch 6 replicate pens of 6 chicks were randomly assigned to 1 of 7 (experiment 1) or 5 (experiment 2) dietary treatments for 21 d. On d 4, 7, 14, and 21, twelve chicks per treatment (2 chicks/pen) ...
The competitive exclusion (CE) action of Aviguard (AG) and its effects on the antibody response of chicks were evaluated in this study. We observed that AG protected the chicks from overwhelming colonization. Fourteen days after infection, fewer AG-pretreated than nonpretreated chicks shed salmonellae from their coloaca in both infected groups, although much less from SE-infected chicks. Antibo...

This experiment was conducted with male chicks to investigate the influence of hormones and nutrients on the development of fatty liver syndrome (FLS) as well as the effects of dietary lipotropic factors on hepatic fat accumulation and lipogenic enzyme gene expression. A total of two-hundred sixteen 4-wk-old Hy-Line male chicks were divided into six groups and fed an experimental diet (T1, low-...
AIMS To determine the effect of antimicrobial selective pressure on the transmission of antimicrobial resistant and sensitive strains of Salmonella in poultry. METHODS AND RESULTS Eight pens housed 12 broiler chicks each. Two chicks in four of the pens were inoculated with a Salm. Typhimurium strain resistant to 12 antimicrobials (including tetracycline), and two chicks in each of the four ot...
