Chemical Composition and In Vitro Gas Fermentation Evaluation of Selected Cereal Stovers Hay
Abstract
The study investigated the chemical composition and In vitro gas fermentation evaluation of selected cereal stovers hay. Thus, the study was carried out to determine the nutritive value of these selected cereal stovers processed to hay using proximate analysis to x-ray the nutrient composition and in vitro gas fermentation technique. The dry matter (DM), crude protein (CP), crude fibre (CF), nitrogen-free extract (NFE), ether extract (EE), Ash, non-fibre carbohydrate (NFC) organic matter (OM), carbohydrate (CHO) and fibre fractions (neutral detergent fibre (NDF), acid detergent fibre (ADF), and acid detergent lignin (ADL), cellulose and hemicellulose of selected cereal stovers hay were significantly (P < 0.05) different except for ether extract (EE) that was similar across the treatments. The in vitro gas fermentation parameters such as methane (CH4), total gas volume (TGV), fermentation efficiency (FE), organic matter digestibility (OMD), dry matter degradability (DMD), short chain fatty acid (SCFA) and metabolisable energy (ME) varied significantly (P < 0.05) across the treatments. Furthermore, in vitro gas fermentation characteristics such as zero time which idealy reflects the fermentation of soluble fraction (a), extent of gas production from insoluble but degradable fraction (b), potential extent of gas production (a+b) and rate of gas production at time (c) were similar across the treatments, however, incubation time (t) and (mlh-1), volume of gas produce at time (Y) varied significantly (P<0.05). The results of chemical composition and in vitro gas fermentation evaluation obtained in this study indicate that ruminant livestock farmers can utilise these unconventional feed resources as basal diet with concentrates supplement when fed out to ruminant animals.
