An international group of scientists, supported by Islamic Azad University, has conducted a study on how dietary green tea powder affects the immunologic parameters of broiler chicks and concluded that green tea feed supplementation is not likely to be able to induce any negative effects on immunological parameters. We would probably have never pay attention to a research in the style of “another way to make sure that nothing has changed”. But… The abovementioned study gives references to different works devoted to effects of green tea powder supplementation in the daily ration of broilers. It appears that green tea improves improve feed conversion ratio — it means that you can feed chicks less, but they would still gain weight alright. Besides, with green tea intake, proportions of some parts of the carcase were influenced. “Proportion of thigh meat was increased by feeding 1.5% green tea powder while that of wing meat decreased; at the same time the quantity and percentage of abdominal fat decreased significantly”.
So if you are considering to include green tea in your personal weight control program, do not forget about possible changes in the proportions of some parts of the carcase.
It is probably worth mentioning that the inclusion of green tea in the diet of domestic animals has not only experimental nature and is associated not only with broilers. In Boseong, South Korea, and in Japan, some farmers feed green tea to pigs and then make special cutlets with their meat, for example. Must be delicious.
