Previous studies (Chaudhry and Miller,1990) have shown the effectiveness of CaO, NaOH and alkaline hydrogen peroxide (AHP) in improving the in vitro dry matter digestibility (IVDMD) of wheat straw (WS). Based on those results, therefore, an experiment was planned to test the effectiveness of some of the selected treatments in improving ruminal and total tract digestibilities by sheep of WS (Norman), treated on a large scale. Rumen conditions were also characterised to see if there was any relationship between digestion and the rumen conditions.

This study evaluated the effects of sodium hydroxide (NaOH) treatment on the nutritional value of Arundo donax (A. donax). Its ultimate goal was to develop an environmentally friendly animal feed alternative that could be produced sustainably while combatting the spread of A. donax. Plants were collected and dried at 60 °C in an oven with controlled air circulation to determine the dry matter (DM) content. The dry plant material was then sprinkled with an NaOH solution of 2%, 4%, 6%, or 8% and placed in leak-proof containers for four weeks. The chemical and in vitro digestibility properties of treated and untreated A. donax samples were analysed in triplicate. The treatment led to significant decreases in neutral detergent fibre (NDF) from 81.06% DM to 69.39% DM, acid detergent fibre (ADF) from 46.99% DM to 43.19% DM, and ether extract (EE) from 2.06% DM to 1.39% DM, in the untreated samples compared with those treated with 8% NaOH, respectively. In addition, DM digestibility increased from 24.61% to 33.78%, ash content from 11.75% DM to 19.92% DM, and ADL from 7.43% M to 15.38% DM. Thus, treatment of A. donax with an 8% solution of NaOH concentration improved its nutritional value.

Dry Matter Digestibility

Summary. This study compared the effect of different levels (24–160 g/kg DM) of NaOH alone or in combination with 2 levels (130 or 260 g/kg straw DM) of H2O2 (alkaline hydrogen peroxide, AHP) in improving in vitro dry matter digestibility of wheat straw. The study also examined the role of filtration or a water wash of straws treated at a regulated pH (± s.d.) of 11.5 ± 0.2 to maximise the effects of NaOH and AHP on in vitro dry matter digestibility. The experiment was a 3 × 2 × 3 factorial design, replicated twice, and included 3 straw groups (pH-control, NaOH-control, AHP), each treated with 2 volumes of chemical solutions (high, 26 L/kg DM containing 48 or 160 g NaOH alone or 160 g NaOH plus 260 g H2O2 ; low, 13 L/kg DM containing 24 or 80 g NaOH alone or 80 g NaOH plus 130 g H2O2 ) and each was subdivided into 3 groups for storage (unfiltered, filtered, washed). Both NaOH-control and AHP reduced (P<0.001) neutral detergent fibre content and increased (P<0.001) in vitro dry matter digestibility of straw compared with pH-control. However, AHP was more effective (P<0.001) in reducing neutral detergent fibre and increasing in vitro dry matter digestibility of straw compared with NaOH alone. Filtration and washing of treated straws increased (P<0.001) neutral detergent fibre and reduced (P<0.001) in vitro dry matter digestibility compared with unfiltered samples of treated straws. High volumes of chemicals were more effective (P<0.001) in reducing neutral detergent fibre content and improving in vitro dry matter digestibility of straws compared with those treated with low volumes of chemicals. While regulation of pH around 11.5 was effective in reducing neutral detergent fibre and enhancing in vitro dry matter digestibility the use of filtration or a water wash of straws following chemical treatments is not recommended.

Chaudhry and Miller (1993) have demonstrated the effectiveness of Alkaline hydrogen peroxide (AHP) in improving in vitro digestibility (IVD) of cereal straws. Further experiments were conducted to evaluate the use of AHP on a larger scale compared with varying amounts of sodium hydroxide (NaOH) in improving the nutritive value of wheat straw (WS) for sheep.
