Extract

The treatment of straw using ammonia released by the hydrolysis of urea and subsequent improvements obtained in digestibility of straws have been reported (Jayasuriya & Pearce, 1983; Williams, Innes & Brewer, 1984). Benefits achieved by this method compare well with those obtained by sodium hydroxide (Verma, 1983). Urea is widely and cheaply available in many developing countries; this favours its use in improving nutritive values of low quality roughages. In addition, this method is relatively safe, uncomplicated and inexpensive compared with some other chemical treatments. Considerable attention has been paid to the treatment conditions for treating cereal straws with liquid or anhydrous ammonia which lead to the optimum effects (Waagepetersen & Vestergaard Thomsen, 1977; Solaiman, Horn & Owen, 1979; Borhami & Sundstøl, 1982), but equivalent studies on the ammoniation of crop residues through urea are limited (Cloete & Kritzinger, 1984; Singh & Negi, 1985). No report is available on the changes in in sacco dry-matter digestibility (DMD) of urea ammoniated straw during treatment at different temperatures. This paper describes our observations on the changes in in sacco DMD of urea ammoniated wheat straw at different treatment times and temperatures.
