Abstract:

This study was aimed to investigate the effects of supplementation of dried molasses sugar beet pulp (3%, 5%, 7%, 10%, 15%, 20% and 25%, fresh material basis) on the silage quality, in vitro organic matter digestibility (IVOMD) and metabolisable energy (ME) content of wet tomato pomace (WTP) silage. All the treatments consisted of five replicate silos, and they were prepared in 1.5 L glass jar silos. The ensiling of WTP with dried molasses sugar beet pulp including molasses (DMSBP) had a significant effect on the chemical composition, ME and IVOMD of silages. Dry matter, crude ash, ME and IVOMD values of silages were increased with supplementation of DMSBP levels (P<0.001). Crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF) contents of silages were decreased with increasing level of DMSBP (P<0.001). Ammonia nitrogen (NH3-N) and lactic acid contents were decreased with increasing level of DMSBP (P<0.001). Propionic acid contents of silages were increased with increasing level of DMSBP (P<0.001). Butyric acid was not detected in any silage groups. As a result, tomato pomace can be ensiled with DMSBP without decreasing the quality criteria of silage.
