Straw Quality

Straw components of 14 wheat, oat and barley cultivars grown at four locations, 1975–1976, were compared for feed quality attributes before and after ammoniation. Based on a combined statistical analysis, significant differences (P < 0.05) among cultivars occurred among and within crops for crude protein (CP), in vitro digestible organic matter (DOM) and crude fibre (CF) for untreated straw residues. Average CP and DOM levels were lowest for wheat (3.6 and 36.7%, respectively). Barley had the highest average CP (4.9%) and oats the highest average DOM (39.8%). Wheat straw had substantially higher average CF than either oats or barley. Straw from Pitic 62 wheat, Random oats and Fergus barley showed superior quality attributes (high DOM and CP, low CF) for their respective crops. Neepawa wheat straw appeared to have the poorest quality overall. The straws were treated with anhydrous ammonia (5% on a wt/DM basis) and left in a sealed container at 20° and 15% moisture for 6 days. Following ammoniation: all wheat cultivars had higher CP levels than the oat and barley cultivars; average improvements in CP for wheat, oats and barley were 8.1, 4.7 and 5.3 percentage units, respectively; average DOM levels were similar for wheat, oats and barley; average improvements in DOM were 8.6, 6.1 and 6.6 percentage units, respectively. Neepawa had significantly higher CP following ammoniation than the oat or barley cultivars and showed the highest improvement in DOM (10.1 percentage units). Based on DOM values of the wheat, oat and barley straws, the cultivars Pitic 62, Random and Fergus would still be preferred after ammoniation. There was little to choose between several cultivars within crops for CP content after treatment with ammonia.

Fiber Digestion

Two types of anaerobic fungi were isolated from the rumen of a sheep fed wheat straw. The fungus producing a mycelium in culture digested significantly more organic matter, neutral detergent fiber, acid detergent fiber and cellulose from straw than the type producing a sporangium from "spherical bodies."

Fermentation Parameters

In the present study, rumen microbial groups, i.e. total rumen microbes (TRM), total anaerobic fungi (TAF), avicel enriched bacteria (AEB) and neutral detergent fibre enriched bacteria (NEB) were evaluated for wheat straw (WS) degradability and different fermentation parameters in vitro. Highest WS degradation was shown for TRM, followed by TAF, NEB and least by AEB. Similar patterns were observed with total gas production and short chain fatty acid profiles. Overall, TAF emerged as the most potent individual microbial group. In order to enhance the fibrolytic and rumen fermentation potential of TAF, we evaluated 18 plant feed additives in vitro. Among these, six plant additives namely Albizia lebbeck, Alstonia scholaris, Bacopa monnieri, Lawsonia inermis, Psidium guajava and Terminalia arjuna considerably improved WS degradation by TAF. Further evaluation showed A. lebbeck as best feed additive. The study revealed that TAF plays a significant role in WS degradation and their fibrolytic activities can be improved by inclusion of A. lebbeck in fermentation medium. Further studies are warranted to elucidate its active constituents, effect on fungal population and in vivo potential in animal system.
