The effect of feeding a Lactobacillus-based probiotic on intestinal intraepithelial lymphocyte (IEL) subpopulations and subsequent protection against coccidiosis was investigated in broiler chickens. Day-old male broilers were fed standard rations without control (CONT) or with a commercial probiotic (PROB) Primalac. Differences in IEL subpopulations were assessed by flow cytometry at 21 d post...

The effect of medicinal plant (Sangrovit), probiotic (PrimaLac), and organic acid (Selko-pH) as feed additives, on fecal excretion of Campylobacter (cfu/g) on broilers were evaluated. Other measurements such as performance, immune response and serum lipids were determined. A total of 300 broilers (Cobb 500) were fed unsupplemented diet (negative and positive controls), feed containing probiotic...

introduction: dietary supplementation of medicinal plants as antibiotic replacement is a new approach in modern poultry farming systems. in poultry production, the main effects of medicinal plants are focused on the intestinal tract and its microbial flora. one of these medicinal plants is cinnamon that is known with scientific name cinnamon zeylanicum. cinnamon verum (syn. cinnamomum zeylanicu...

A study was conducted to determine 1) the effect of a dietary direct-fed microbial (DFM) on turkey poult performance, 2) the effect of a DFM on a Salmonella challenge, and 3) the effect of feed processing on the efficacy of the dietary DFM. Day-of-hatch Large White female poults were placed in 2 rooms in 2 Petersime batteries per room. Twelve pens of 7 birds each were used in each battery (24 p...

Campylobacter is known to be one of the most common causes of human intestinal disorders. Since poultry are known to be the main reservoirs for this pathogen, decreasing this bacterium in intestinal tract could be beneficial in reducing contamination of poultry products. The effects of probiotic (PrimaLac), medicinal plant (Sangrovit) and organic acid (Selko-pH) as broiler feed additives on cec...

Background: Coccidiosis is the most common parasitic disease in poultry, ionophore antibiotics are preferred drugs for controlling this disease. However, prolonged use of ionophores will result in Eimeria deformation and resistance to these drugs. Aims: The aim of this study was to compare the effects of probiotic and prebiotic, that is used to boost d...
