This study aims to determine the effects of adding different fumaric acid (FA) levels to tea factory wastes (TFW) produced by different cultivation methods on in vitro true digestibility. In vitro true digestibility of feed (IVTDAs feed), dry matter (IVTDDM), organic matter (IVTDOM), and neutral detergent fibre (IVTDNDF) were performed with a Daisy Incubator. Fumaric acid did not add to the control group and added 0.1%, 0.2%, or 0.3% FA to the experimental groups. When the cultivation methods were compared (conventional and organic tea wastes), it was seen that FA made a significant difference (P<0.05) in conventional tea wastes at all levels. However, when comparing organic and conventional tea wastes themselves, there was no significant effect of FA level on digestibility parameters (P>0.05). There was a significant difference (P<0.05) for IVTDAs feed, IVTDDM and IVTDOM values in interaction between treatment and cultivation methods. The research results showed that the digestibility values of the conventional tea wastes were higher for ruminants than the tea waste produced by the organic method, and the use of 0.3% FA in organic tea wastes had a positive effect on IVTD values for ruminants.
