ABSTRACT

 

Mosleh N, Shomali T, Hamedi S., Effects of green tea Camellia sinensis on performance, feed conversion and jejunum histology in broilers, Onl J Vet Res., 15 (2): 147-154, 2011.  Effects of green tea powder on performance, D-xylose absorption and jejunum histology in thirty 21-day old broiler chickens of both sexes were investigated. Birds in untreated controls gained higher body weight than birds treated with green tea powder. No significant differences were observed in plasma D-xylose concentrations in any groups. Green tea consumption did not affect jejunum villus width, height/crypt depth ratio or epithelial cell area. However, villus height, area and crypt depth increased in treated birds. We find that 1% green tea supplement reduces weight gain and increase FCR in broiler chickens, effects which do not appear to be related to changes in jejunum morphology.

 

Key words: Green Tea; Performance Parameters; Jejunal Histomorphometry; Broiler Chickens.
