Özet

This study was conducted to evaluate in vitro gas and methane production, gas production parameters (a + b, c), organic matter digestibility (OMD), metabolic energy (ME) and net energy lactation (NEL) of wheat straw treated with silage effluent. Groups were formed as wheat straw (control group, (W)), straw treated with urea + molasses (WUM) and silage effluent (WS), water, urea and molasses (WHUM), water (WH), 50% silage effluent +50% water + urea + molasses (WSHUM), and then except for control group, treatment groups were subjected to 45 days anaerobic fermentation. Crude protein and crude ash contents of the straw groups treated with silage effluent were increased (P<0.01), and cell wall elements such as ADF and NDF of the treatment groups were decreased (P<0.01). In addition, OMD, ME and NEL contents and in vitro gas production (IVIG) values of straw were increased by treatment with silage effluent (P<0.01). It was determined that the addition of urea and molasses to wheat straw did not affect the production of methane according to the control, and in vitro gas production parameters were improved (P<0.01). In conclusion, in order to improve feed value of wheat straw, it may be treated with silage effluent cauising environmental pollution and nutrient loss, and further works should be carried out to illuminate the subject.
