Potential of Cranberry Extracts as Immuno-Modulatory Agent in Organic Broiler Chicken Production
نویسندگان
چکیده
Cranberry (Vaccinium macrocarpon Ait.) has received considerable attention for its putative human health benefits. Most of the focus is on its phenolic compounds including phenolic acids, anthocyanins, flavonols, flavan 3 ols and the polymer classes of procyanidins and proanthocyanidins. Research in our laboratories has revealed that crude cranberry extracts can disrupt the cell envelope in Listeria, Escherichia coli, Salmonella, and S. aureus, activity which parallels that of antibiotics widely used as growth promoters in the poultry industry. The plant proanthocyanidins are well known to improve nitrogen nutrition in ruminant animals and as a powerful antioxidant with beneficial effects on human health and immunity. Limited laboratory research has examined the biological effect of cranberry extract using animal models. The purpose of the present work was to discuss progress being made in evaluating the potential for utilizing cranberry as an immune-modulatory agent in organic broiler chickens production.

Effect of Citrus Seed Extracts on Oxidative Stabilityof Raw and Cooked Chicken Meat
The potential of extracts prepared from seeds of three citrus species (orange, lemon and grapefruit) to stabilize lipid oxidation of cooked and raw broiler meat under refrigeration storage was evaluated and compared with butylated hydroxyl anisole (BHA), a synthetic antioxidant. The citrus seed extracts were separately applied at a rate of 1.5% of the weight of the meat. There was a negative co...

The use of antibiotics in food-producing animals has significantly increased animal health by lowering mortality and the incidence of diseases. Antibiotics also have largely contributed to increase productivity of farms. However, antibiotic usage in general and relevance of non-therapeutic antibiotics (growth promoters) in feed need to be reevaluated especially because bacterial pathogens of hu...
متن کاملEvaluation of the environmental impact of broiler chicken production by industrial and traditional methods using the Life Cycle Assessment
Poultry meat with a high share in the food consumption is one of the most basic products for supplying protein to households. Due to the high amount of pollutants in this part, the environmental impact of the production of this product is necessary. In the present study, the environmental impact of broiler chicken production in both industrial and traditional breeding methods were evaluated ...

Consumers believe that quality of foods from organic production is superior to foods from conventional production. The objectives of the present study have therefore been to compare the quality of chicken meat from organic and conventional production on the basis of traditional meat quality criteria. The experiment was organized as a field study. Fresh organic broiler carcasses were purchased d...
