The effects of fumaric acid on in vitro true digestibility of tea wastes produced with different cultivation methods

Abstract

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 (P0.05). There was a significant difference (P
