Urea-ammonia treatment of straws in the tropics involves mixing 1.0 kg of air dry straw with 1.0 kg of a 40 g/kg urea solution and storing under plastic for at least 4 weeks (Schiere and Ibrahim, 1989). The economics of treatment is dependent on the cost of urea. Treatment cost would reduce, if on-farm-produced urine, e.g. cow urine, could be used as a source of urea. However cow urine is dilute and may contain only 10 g/kg urea or less (Owen, 1993). The present study therefore investigated varying concentrations of urea solution for treating wheat straw at a tropical temperature.

Rumen fungi produce a wide range of polysaccharide degrading enzymes during growth on cell walls and can degrade 0.25 -0.65 of plant tissue dry weight in pure cultures (Orpin, 1983). It has been proposed that sodium hydroxide may break-down hemicellulose and cellulose and expose them to microbial attachment and improve digestibility (Gotoet al., 1993). The aim of the present study was to determinein vitrorumen fungal growth using a quantitative competitive PCR assay (QC-PCR) and dry matter (DM) and neutral detergent fibre (NDF) disappearance from a medium containing untreated (US) or sodium hydroxide treated wheat straw (TS).

Nutrient Digestion

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.

In Sacco

Fungal treatment has been recently considered as a promising method for improving the nutritive value of straw (Zadrazil et al., 1997). Several studies have been conducted to identify species of white-rot fungi for assessing their ability to improve the nutritive value of straw (Yamakamwa et al., 1992). Since there are many species of fungi in nature, there is an interest in characterising of some species. The objectives of this experiment were to study the effect of five Pleurotus fungi on the chemical composition, in vitro digestibility and in sacco degradability of wheat straw and evaluate their effect in upgrading the nutritive value of lignicellulosic materials.

In Vitro Digestibility

The effects of temperature, treatment time and levels of SO2 and NH3 on the in vitro digestibility and chemical composition of corn stover and barley straw were evaluated. Sulphur dioxide improved (P > 0.05) in vitro dry matter digestibility (IVDMD) and in vitro cell wall digestibility (IVCWD) of corn stover when treated at 70 °C for 24 h. However, high SO2 levels (4 and 6%) at higher temperature (90 °C) and for a longer time (72 h) reduced (P < 0.05) IVDMD and IVCWD and increased (P < 0.05) lignin content. When barley straw was treated with SO2 at 70 °C, IVDMD and IVCWD were greater (P < 0.05) when the treatment was carried out for 72 h than for 24 h. The improvement in in vitro digestibilities with SO2 was associated with solubilization of large amounts of hemicellulose. Ammonia treatment at 70 °C for 24 h reduced (P < 0.05) hemicellulose content and increased (P < 0.05) IVDMD and IVCWD as well as apparent lignin content. Suphuration enhanced the effect of ammoniation on IVDMD and IVCWD and reduced lignin content, but did not further reduce hemicellulose over NH3 alone in both crop residues. Improvements in in vitro digestibilities obtained with NH3 treatment followed by SO2 were associated with reductions of hemicellulose and lignin. Sulphur dioxide and NH3 treatment at 70 °C for 24 h produced a greater improvement in IVDMD and IVCWD in barley straw than in corn stover. Treatment with SO2 following ammoniation further increased (P < 0.05) NH3-N and sulphur contents of corn stover.

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.
