“…Similar effects of increased CP in poor quality forages as a result of ammoniation were reported in wheat straw (Soleiman et al, 1979), Barley straw (Graham & Aman, 1984), limpograss (Brown et al, 1987), and tall fescue straw (Kallenbach et al, 2006). The increased CP observed can be explained by both the nitrogen added and the ammonolysis reaction between the carbohydrates and the alkali as previously reported (Dryden & Kempton, 1983;Alibez et al, 1984;Mason et al, 1990b;Kondo et al, 1992).…”

The study was undertaken to determine the effects of ammonium hydroxide (NH 4 OH) treatment of sorghum stover residue on composition and in vitro dry matter disappearance (IVDMD) of two sorghum varieties, Dale (tall, sweet sorghum variety) and Brown mid rib (BMR) (Short, grain sorghum variety). The residue was treated with; water only (T00), 50 g NH 4 OH kg -1 residue dry matter (DM) (T50), 100 g NH 4 OH kg -1 DM (T100), and untreated control (neither water nor NH 4 OH) (TUN) and allowed to react for one week before chemical analysis was performed. The fiber content (ADF and NDF) were not affected by the levels of alkali treatment but the crude protein (CP) and Soluble protein contents were both increased by alkali treatment. There was an increase (P < 0.05) in dry matter digestibility in vitro (IVDMD) by NH 4 OH treatment from 529 g kg -1 to 651 g kg -1 in T50 and T100. The improvement in IVDMD may indicate that NH 4 OH helps disrupt the lignin-carbohydrate complexes. The development of more economical and safe procedures which improve digestibility of the structural cell wall components would be very beneficial for improving the use of crop residue as feedstock for livestock and bioethanol production.

“…There was no influence of the 3 doses of urea on the IVDMD and OMDcellulase. This coincides with the observations of Williams et al (1984a) Alibes et al (1984) refer to the necessity of high ambient temperatures to produce optimum results and, in particular, good nitrogen retention. Thus, the limited effectiveness of some treatments (Mandell et al, 1988;Mann et al, 1988) (Williams et al, 1984b) and of moisture content.…”

Summary — Comparative studies were made at a laboratory level to assess the effectiveness of the treatment of straw with anhydrous ammonia (anhydrous NH 3 ) and urea. The influence of moisture, dosage, and temperature were also assessed. The influence of the addition of an urease source was studied in treatments with urea. Two experiments were performed: 1), Anhydrous-NH 3 and urea were used separately to treat a total of 13 samples of barley straw. Anhydrous NH 3 was applied to 3 samples at a dosage of 4% and at moisture levels of 9.2, 22.2 and 32.7%. Urea was applied to 9 batches at doses at 4.3, 6.5 and 8.0% and at 3 moisture levels: 22.2, 31.1 and 42.7%. One sample was left untreated. 2), Urea at a dosage of 3% was applied to 24 samples of wheat straw and 24 samples of maize stover at 4 moisture levels, 10, 20, 30 and 40% and 3 temperatures: 15, 25 and 35 °C for wheat straw and 5, 15 and 25 °C for maize stover. All these parameters were studied both with and without the addition of crude soya bean (CSB).In experiment 1 the increase in moisture content when NH 3 was applied reduced the neutral detergent fibre (NDF) content, but did not modify the in vitro dry matter digestibility (IVDMD) values, which were similar to those obtained on the application of urea at moisture levels of 31.1 and 42.7%. In experiment 2, the increase in moisture content to 30% produced a positive response in most of the chemical parameters analyzed. However, with an increase in humidity to 40% the results were less homogeneous. The temperatures used were not limiting, and only had a significant effect (P < 0.05) on the NDF and total nitrogen (N) contents. For maize stover the temperature did not influence (P > 0.05) either the degree of ureolysis or the IVDMD. The addition of CSB had no significant effect (P > 0.05) when applied to the maize stover, and when applied to wheat straw its only significant effects (P < 0.05) were on the NDF and IVDMD values. At low moisture levels the addition of CSB increased the degree of ureolysis in wheat straw. straw I chemical treatment I anhydrous ammonia / urea / moisture / temperature / urease

“…HernaH ndez et al (1994) showed an intake of 35)6 g DM kg\ 0)75 day\ 1 for barley straw in goats, and Degen et al (1997), for goats given two different species of Acacia trees (Acacia saligna y salicina), found an intake of 27)1 and 14)6 g DM kg\ 0)75 day\ 1 , respectively. However, these low intakes were improved when the protein content of forages was increased by ammonium (Alibes et al, 1984;Fondevila et al, 1993;HernaH ndez et al, 1994) or soya meal supplementation (Alrahmoun et al, 1985).…”
