Effects of green tea on performance, feed conversionand jejunum (histology) in broilers

摘要

Effects of green tea powder on performance parameters, D-xyloseabsorption and jejunal histological parameters of thirty 21-day old broiler chickens of bothsexes were investigated. Birds in untreated controls gained significantly higher body weightthan birds treated with green tea powder. No significant differences were observed inplasma D-xylose concentrations in any groups. Green tea consumption did not affectjejunum villus width, height/crypt depth ratio or epithelial cell area. However, villus height,area and crypt depth increased in treated birds. In conclusion, 1% green tea in diet, appearsto be able to lower body weight and increase FCR in broiler chickens at no apparentdetriment to jejunal mucosa.
