“…It has been hypothesized that any improved performance might result from a decreased rate of digestion and hence rumen escape of nitrogen and nonfiber components of the ammoniated barley, resulting in the improved efficiency (Robinson and Kennelly 1988a, b;1989 Laksesvela and Slagsvold (1980), Laksesvela (1981), Low and Kellaway (1983) and Mandell et al (1988) (Mathison et al 1991). A greater incidence of bloat was observed when whole rather than rolled grain was fed (23 vs. 4 cases) which confirms results of Mathison et al (1991).…”

“…Some research has indicated that ammoniation may improve the feeding value of grain (Montgomery et al 1980;Phillip et al 1985;Mandell et al 1988;Mathison et al 1989a; Robinson and Kennelly 1989). Of particular interest are the observations that the disestibility of whole grain may be improved ivhen it is ammoniated (Laksesvela and Slagsvold 1980;Mowat et al 1981;Low and Kellawav 1983).…”

“…Laksesvela and Slagsvold (1980) and Laksesvela (1981) Robinson and Kennelly (1988b) noted that as ammoniation levels were increased the rate of decline in pH in the rumen after feeding was reduced. Results from in situ and in vivo studies (Rode et al 1986;Mandell et al 1988) confirm that whole ammonia-treated barley is degraded more slowly and possibly less completely in the rumen than control grain. Data of Robinson and Kennelly (1988a,b) (Mathison et al 1989).…”

The effectiveness of ammonia and sulfur dioxide as preservatives for high-moisture barley grain and their influence on digestibility, rate and efficiency of gain, and the selenium and thiamin status of feedlot steers were examined. Duplicate 18-t plastic-bag bins were prepared with the following type and amount (wt/wt, dry matter (DM) basis) of preservative applied to low (23%) or high (32%) moisture barley: (1) high-moisture barley, no preservative (control); (2) high-moisture barley, 1.1% ammonia (1.1%-NH3); (3) high-moisture barley, 2.3% ammonia (2.3%-NH3); (4) low-moisture barley, 1.3% sulfur dioxide (1.3%-LMSO2); and (5) high-moisture barley, 1.7% sulfur dioxide (1.7%-SO2). Heating occurred in the control barley. Mold and yeast populations were substantially reduced in barley treated with ammonia which appeared well preserved. Considerable deterioration occurred in the core of one 1.3%-LMSO2 bin. Crude protein digestibility was lower (P < 0.001) for an all-concentrate diet containing 1.1%-NH3 barley fed whole (66.8%) than for three other diets containing rolled barley (mean 81.1%), although apparent digestibilities of other feed components were similar (P > 0.05). When the preserved grains were each fed to a group of 12 steers (363 kg initial weight) along with 1.0 kg hay daily, gains were 1.46, 1.72, 1.67, 1.33 and 1.31 kg d−1 (P < 0.05) for steers fed control, 1.1%-NH3, 2.3%-NH3, 1.3%-LMSO2, or 1.7%-SO2-treated barley, respectively. Corresponding kilograms of DM required per kilogram of grain were 6.11, 5.41, 5.53, 6.76, and 6.72 (P < 0.05). Serum selenium concentrations and thiamin status were similar (P > 0.05) for steers in all treatments at the end of the test. Key words: High-moisture barley, steers, preservatives, ammonia, sulfur dioxide

This study compared the efficacy of plastic glitter, with a mean particulate size of 1.18 mm, as a faecal marker in group-housed captive wombats Lasiorhinus latifrons. The wombats voluntarily consumed the glitter through the use of appetizing food vehicles. Over 40 different food treats were tested as possible vehicles for the oral delivery of the faecal marker and of these six were deemed highly palatable: (1) golden syrup with horse pellets, (2) golden syrup with weetbix, (3) pitted dates, (4) honey with kangaroo pellets, (5) nutrigel with rolled-oats, and (6) strawberry sauce with rolled-oats. Mean transit time of glitter particulates through the alimentary tract of L. latifrons was 2.9 ± 0.5 d, with maximal output occurring 4.2 ± 0.3 d after administration. A marker dose of 1.6 g / 3 d was required to reach a steady and detectable state of marker output. Using this dosage > 2 particulates (i.e. flecks) of glitter were defaecated in > 90% of faecal pellets, allowing the accurate identification of individual samples. Reliable labeling was obtained using gold, silver, metallic red, metallic green, metallic blue and white glitter, i.e. digestion did not affect the integrity of these colours. There was no evidence that long-term feeding of glitter had any negative effects on the normal formation of faecal pellets, the clinical health, weight or appetite of the wombats.
