Ammonium Hydroxide Treatment on Wheat Straw

“…Average daily gain of the lambs fed the 0, 3, 6 and 9% un-neutralized NaOH-treated straw was 43.8, 153.4, 66.6 and -4.0 grams, respectively. Straw dry matter and organic matter digestibility tended to increase linearly with the level of NaOH which was consistent with the results of Wilson and Pigden (1964). However, animal performance was more closely related to feed intake rather than observed digestibilities.…”

“…In a study conducted by Wilson and Pigden (1964), various amounts of NaOH was sprayed onto straw, while water was added at a constant rate of 30 ml/100 g of straw OM. The treated wheat straw was then allowed to reactfor different periods of time prior to analysis.…”

“…A still simpler and cheaper method to reduce the DM loss and water required for washing in the Beckmann procedure was introduced by Wilson and Pigden (1964). Sodium hydroxide solution was sprayed at various levels while water was added at a rate of 30 ml/100 g of straw dry matter.…”

“…Hasimoglu et al {1969) conducted a lamb performance study to evaluate the spray method of Wilson and Pigden (1964). Wheat straw mositure level was raised to 50% and NaOH was sprayed at a level of 4% of dry matter.…”

Wheat Straw and Sodium Hydroxide Treatment in Beef Cow Rations

“…Straw was chopped to a length of approximately 4 cm and brought to about 50% moisture. NaOH was added to supply 4 g NaOH/100 g DM in a manner similar to the spray treatment of Wilson and Pidgen (1964 CAd libitum fed.…”
