The immune and intestinal epithelial cells are particularly sensitive to the toxic effects of deoxynivalenol (DON). The aim of this experiment was to study the effects of DON and/or a microbial feed additive on the DNA damage of blood lymphocytes and on the level of thiobarbituric acid reactive substance (TBARS) as an indicator of lipid peroxidation and oxidative stress in broilers. A total of ...

Since the use of antibiotics in animal feeds has been banned, researches on alternative natural products that modulate ruminal fermentation have been intensified. Natural compounds such as plant extracts have been considered to be replaced antibiotics as safe and sustainable alternatives. Plant extracts especially essential oils and saponins have strong antimicrobial, antiparasitic, antiprotozo...

this experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. one hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...

Feed additives are nonnutritive feed ingredients that are not required by swine. In the absence of feed additives in the diet, no deficiency symptoms will result. They may, however, enhance production and profitability under the right circumstances. Feed additives are regulated in the U. S. by the Food and Drug Administration (FDA), and it is very important that the regulations be followed. The...

Phytogenic feed additives are plant-derived products used in poultry feeding to improve overall performance of broilers. In this study, 588 one day-old Cobb 500 chicks were fed one of four diets and housed on either dirty or clean litter for 3wks. Treatments included: Group I: commercial diet with no additive and housed on clean litter; Group II: commercial diet with no additive and housed on d...

This study aimed to investigate the efficacy of a feed additive containing bentonite and enzymatically hydrolyzed yeast on intestinal health growth newly weaned pigs under chronic dietary exposure fumonisin aflatoxin. Newly were randomly allotted one four possible treatments: control diet conventional corn; corn contaminated with aflatoxin; mycotoxin-contaminated 0.2% additive; mycotoxin 0.4% a...
