This study was carried out to evaluate the effect of onion extract on growth performance, carcass characteristics and some blood metabolites in Ross and Cobb broiler chickens. One hundred sixty, 1-d-old broiler chickens (mean initial weight: 36.5 ± 1 g) of male sex (Ross-308 and Cobb) were randomly conducted as randomized complete design with 4 treatment and 4 replication. The experimental grou...

this study was conducted to investigate the effects of the medicinal plant yarrow (achillea millefolium l.), a probiotic (primalac) and an antibiotic (virginiamycin) on gastrointestinal tract (git) characteristics, microbial populations, immune response, serum lipids and growth performance of broiler chickens. a total of 250 one-day old male broilers (ross 308) were randomly allocated to 5 trea...

aim: the objective of this study was to evaluate the time trend of helicobacter pylori ( h. pylori ) prevalence and presence of intestinal metaplasia over the period of 7 years in gastritis iranian patients. background: h. pylori are the major causal factor in chronic gastritis. its acquisition leads to a chronic, usually lifelong, inflammation of the gastric mucosa, which may gradually progres...

background host genetic and environmental factors are involved in development of gastric cancer. tumor necrosis factor (tnf)-î±| has a key role in helicobacter pylori -induced gastritis. we analyzed the association between tnf-î± polymorphism and the risk of gastric cancer in an iranian population residing in northeastern iran. materials and methods in a case-control study, the genotyping was c...

An indirect immunoperoxidase method was used to visualise immunoglobulin-containing cells in the large intestinal mucosa of 10 children who had defunctioning colostomies. Intestine deprived of its usual exposure to intraluminal antigens contained less immunocytes per unit area than intestinal mucosa subjected to normal stimulation by dietary and microbial antigens. These findings substantiate i...

This experiment was conducted to compare the effects of multi-strain probiotic inclusion levels on performance, intestinal morphology, gut microflora and hematological changes in Salmonella typhimurium (ST) infected broiler chickens. A total of 120 day old Ross 308 broiler chickens were distributed into 20 floor pens and reared for 10 days under 5 experimental treatments including a corn-soy ba...

In the present experiment, 320 one day old Ross 308 broiler chickens were used completely randomized design with 4 treatments, 4 replicates, and each replicate contained 20 broiler chickens. Experimental treatments include control, 0.5, 1, and 2% of Thymolina powder in chickens’ diet. Thymolina is an antibacterial powder drug which is made by composing 4 medicinal plants. A significant differen...
