“…Lambs fed the US diet had higher ruminal ammonia N over those fed UT and NT diets by 42.9% (p<0.05) and 88.7% (p<0.001), respectively. This increase is apparently due to the increase of degradable urea, thus agrees with the results of Herrera Saldana et al (1982) and Streeter and Horn (1984). The higher rumen ammonia N concentration with US treatment as compared to UT treatment is consistent with the results obtained by Djajanegara and Doyle (1989), Zorrilla-Rios et al (1989) and Mgheni et al (1994) who reported that ammoniation of straw yielded lower (p<0.01) rumen ammonia N concentration than urea supplementation straw.…”

“…In all diets, rumen acetate formed the highest proportion, followed by propionate and butyrate. This trend indicated that the diets had a similar fermentation pattern in the rumen, which agrees with the results of Herrera Saldana et al (1982) and Mgheni et al (1994) who reported that total VFA concentration did not differ among treatments (p>0.05), and that no differences existed in molar proportion of the individual fatty acids among the untreated and ammoniated straw diets. Rumen fermentation parameters did not vary significantly with the addition of SBM, however valerate tended to be lower (p = 0.08) with SBM addition.…”

“…These results are consistent with several other reports where sheep were fed diets containing wheat straw supplemented with urea, or treated with urea or ammonia (Dais-da-Silva andSundstol, 1986, 1989;Kraiem et al, 1991) or either sorghum stover (Ben Salem et al, 1994) or barley straw (Hadjipanayiotou, 1982) treated with urea. On the contrary, neither DM nor OM digestibility was altered by diets containing ammoniated wheat straw (Herrera Saldana et al, 1982) or urea treated maize stover (Manyuchi et al, 1994). In the present study, both urea treatments (UT or US diet) increased fiber (CF, NDF, ADF, cellulose and hemicellulose) digestibilities when compared with NT diet.…”

The effect of ammoniation with urea and with soybean meal (SBM) as a source of urease on the nutritive value of wheat straw was evaluated in sheep. Twenty-four male Najdi lambs were used in a 3×2 factorial design, in which the animals were allocated to three straw treatments: 0% urea-treated (NT), 6% urea-treated (UT) and 2.2% urea-supplemented (US) straws. Each straw treatment was either supplemented or non-supplemented with 70 g SBM kg -1 straw during the treatment time with urea, giving a total of six straw treatments. Each of these treatments was individually fed ad libitum to 4 lambs, together with 300 g of barley grain/head/day. Total N content of UT and US straws increased significantly (p<0.001) as compared to NT straw. The degree of urea hydrolysis, either with or without SBM addition, was nearly similar. Lambs fed either UT or US straw based diets had significantly (p<0.01) and numerically (p>0.05) higher straw DM intake (g d -1 kg -1 BW 0.75 ), compared to those fed NT straw based diet. Apparent DM or OM digestibilities increased significantly (p = 0.014) in lambs fed UT diet, and numerically (p>0.05) in lambs fed US diet as compared to those fed NT diet. Fiber (CF, NDF, ADF, cellulose and hemicellulose) digestibility increased to a similar magnitude, averaging 20.2 (p<0.001) and 7.8% (p<0.07); this corresponds to 35 (p<0.001) and 51% (p<0.001) in N digestibility and approximately 78 (p<0.017) and 105% (p<0.002) in N retention, for UT and US diets, respectively, as compared to NT diet. However, the UT diet had higher (p<0.01) fiber digestibility over the US diet. Addition of SBM tended to improve (p = 0.09) straw DM and digestible OM intakes, while significantly increasing (p<0.001) total and digestible CP intakes across all diets. Lambs fed on US diet had higher ruminal ammonia N than those fed on UT (p<0.05) or NT (p<0.001) diets. However, ruminal pH and molar proportion of the volatile fatty acids did not differ (p>0.05) among the treatment diets. This study suggests that US and UT treatments, particularly the latter, improved straw intake, digestibility and N utilization by lambs compared to NT treatment. On the other hand, addition of SBM as a source of urease had a negligible effect on urea hydrolysis.

“…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).…”

Evaluation of Sweet Sorghum Bagasse as an Alternative Livestock Feed

2013

Recently, sweet sorghum [Sorghum bicolor (L) Moench] has garnered renewed attention as a promising feedstock for ethanol production. A byproduct of this is bagasse, which is sweet sorghum stalks remaining after juice extraction. It is possible that sweet sorghum bagasse could provide a source of livestock feed and that its nutritive value could be increased by ammoniation. Ammoniation refers to the treatment of low‐quality forages with NH3 to improve crude protein concentration, digestibility, and animal intake. The main objective of this study was to evaluate sweet sorghum bagasse as a livestock feed and determine the effect of ammoniation on in vitro true digestibility (IVTD) and crude protein (CP) of sweet sorghum bagasse. In vitro true digestibility and CP were determined on bagasse of 12 sweet sorghum cultivars grown in three environments and treated with and without anhydrous NH3 (39.0 g kg−1). Across environments, ammoniation increased bagasse IVTD from a mean of 731 g kg−1 dry matter (DM) to a mean of 750 g kg−1 DM, but IVTD of bagasse from only two of three environments was increased. Crude protein averaged 117 g kg−1 DM for ammoniated samples compared to 26 g kg−1 DM for nontreated samples. Ammoniation increased CP in every cultivar and in every environment. Sweet sorghum bagasse IVTD and CP characteristics combined with large yields indicate that this byproduct could serve as livestock feed and merits further investigation.
