Dietary Camellia sinensis Influences the Broilers: A Review

Abstract

This study was conducted in order to understand the impact of using dietary Camellia sinensis in broilers. In this regards several studies were explored and obtained findings were found to be much interesting and useful. In summary it has been reported by researchers that Camellia sinensis supports the feed intake (4480 g/b), water intake (8960 ml/b), live body weight (2356.8 g/b), weekly weight gain (2322.8 g/b), carcass weight (1381.8 g/b) and feed conversion ratio (1.92). Further, it was stated that Camellia sinensis reduces the relative weight of heart, liver, spleen, proventriculus, intestine and fat pad by 13.53, 61.1, 2.26, 58.13, 10.2 and 81.41%, respectively compared to their normal weights. Camellia sinensis enhances the immunity of broilers that results lower infection rate and mortality rate. Concerning digestibility it was indicated by researchers that digestibility of crude protein improves by 80.33%, ether extract by 76%, crude fiber 33.83% and metabolizable energy by 79.66%. In conclusion, Camellia sinensis has been proved an important dietary supplement for the broilers. It supports birds’ immunity, production and performance.
