Abstract

The purpose of this study is determining the in vitro true digestibility values and nutritional content for tea (Camelia Sinensis)  factory waste (TFW) produced by organic and conventional methods. Fresh tea plants and the TFW are collected from tea factories in the Blacksea Region of Turkey on the seasons of tea production which are the beginning and end of May (1st season), July (2nd season) and August (3rd season).  In this study the nutrient composition of TFW, digestible organic material and metabolic energy values were determined in 3rd, 6th, 12th, 24th, 48th, 72nd and 96th hours by in vitro gas production technique. The nutrient values of TFW varied with seasons and periods. Values found are: dry matter (DM) 92-95%, ash values 3.56-4.59%, neutral detergant fiber (NDF) 51.10- 57.23%, acid detergant fiber (ADF) 40.93 – 49.27%,  digestible organic material (DOM) 25.47 – 44.79% and metabolic energy (ME) 4.65 – 8.79 MJ/kgDM. DOM and ME values were found highest at the 3rd season followed by the 2nd season and 1st season (P<0.05). There is no statistical significant difference between   TFW produced by organic and conventional methods for DOM and ME (P>0.05). It was concluded that, after the determination of the percentage of tannin and polyphenol contents in TFW; the 3rd season TFW can be added to ruminant rations which have high feed efficiency.
