Effect of Ammonia Treated Straw with Supplements on Intake and Digestibility of Sheep

Evaluation of Sweet Sorghum Bagasse as an Alternative Livestock Feed

“…Kallenbach et al (2006) reduced neutral detergent fiber (NDF) of tall fescue straw and Buettner et al (1982) decreased NDF, hemicelluloses, and lignin concentration and increased in vitro dry matter disappearance of tall fescue hay; however, acid detergent fiber and cellulose were not affected. Others (Lawlor et al, 1981;Herrera-Saldana et al, 1982;Saenger et al, 1982;Huque et al, 2001) have also observed improvement in fiber digestibility with ammoniation. Typically these materials are treated with NH 3 at 30 to 40 g kg -1 DM, but rates of 1 to 2 g kg -1 DM have proven adequate (Moore et al, 1986) while rates below 1 g kg -1 DM generally are not effective (Glenn, 1990).…”

“…For grass hay, Coombs et al (1989) increased CP from 113 to 194 g kg -1 dry matter (DM) and Gibb and Bauer (1988) increased it from 83 to 151 g kg -1 . Herrera-Saldana et al (1982) improved CP of wheat straw from 36 to 81 g kg -1 DM and Huque et al (2001) increased CP of barley straw from 29 to 88 g kg -1 DM. Others (Mason et al, 1989;Lines et al, 1996;Ballet et al, 1998) have published similar results.…”

“…To improve the feeding value, these materials are treated with steam, NaOH, or CO(NH 2 ) 2 (Caielli, 1986). This technique was shown to improve quality of barley (Hordeum vulgare L.) straw (Alibes et al, 1984;Huque et al, 2001), wheat (Triticum aestivum L.) (Lawlor et al, 1981;Alibes et al, 1984), maize (Zea mays L.) stover (Saenger et al, 1982;Alibes et al, 1984), tall fescue (Festuca arundinacea Schreb.) This technique was shown to improve quality of barley (Hordeum vulgare L.) straw (Alibes et al, 1984;Huque et al, 2001), wheat (Triticum aestivum L.) (Lawlor et al, 1981;Alibes et al, 1984), maize (Zea mays L.) stover (Saenger et al, 1982;Alibes et al, 1984), tall fescue (Festuca arundinacea Schreb.)…”

“…In the United States, anhydrous NH 3 has been used to improve the feeding value of low quality feeds. This technique was shown to improve quality of barley (Hordeum vulgare L.) straw (Alibes et al, 1984;Huque et al, 2001), wheat (Triticum aestivum L.) (Lawlor et al, 1981;Alibes et al, 1984), maize (Zea mays L.) stover (Saenger et al, 1982;Alibes et al, 1984), tall fescue (Festuca arundinacea Schreb.) straw (Kallenbach et al, 2006), mature tall fescue hay (Buettner et al, 1982), and limpograss [Hemarthria altissima (Poir.)…”
