“…It was reported that ammonia treatment increased the digestibility of barley straw by up to about 20% in cattle feeding experiments (28). Similar results in increased digestibility of herbages with ammonia treatment have been found by comparing the digestibility of untreated and ammonia-treated barley straw incubated with rumen contents in vitro or enclosed in nylon mesh bags placed in vivo rumen (9).…”

The microbial populations and fermentation characteristics were compared in the rumina of two rumen-cannulated Holstein steers fed untreated rice straw (RS) and concentrate or ammonia-treated rice straw (ARS) and concentrate. The total volatile fatty acid concentrations in the rumina of both steers were significantly higher when they were fed ARS than when fed RS. The molar proportion of butyric acid when ARS was fed increased significantly, compared with the periods when was fed RS. The population density of protozoa varied only insignificantly with RS or ARS diets. But Dasytricha spp. increased with RS and Entodinium spp. increased with ARS. The viable counts of cellulolytic bacteria were higher with ARS than with RS. The viable counts of sulfate reducing bacteria were lower with ARS, compared with the RS diet. Feeding ARS increased the viable bacterial populations such as Eubacterium spp., Fibrobacter succinogenes, Ruminococcus albus, and Succinivibrio spp. But Bacteroides spp. and Butyrivibrio spp. were dominant when RS was fed.Various physical and chemical treatments of low-quality roughages to improve their nutritive values for ruminants have been tried (11,21). Such physical treatments as grinding, milling and chopping have increased the intake of roughages, but has not improved their nutritive value. Moreover, these treatments had the disadvantage of high costs. On the other hand, chemical treatment with calcium hydroxide, sodium hydroxide or ammonia has been tried to improve their nutritive values and to avoid spoilage during storage. Of the treatments with alkali, the ammonia treatment has the advantages of being relatively inexpensive, simply applied on the farm, and it increases the digestibility and the nitrogen content of the herbage.

“…The influence of increasing temperature on the effect of NH, treatment was demonstrated by Waagepetersen & Thomsen (1977) showing that the IVOMD of barley straw increased with increasing temperature up to 45°C when treatment time was from 3 t o 14 days. Low treatment temperature was at least partly compensated for by increasing the NH, dosage from 3.9 to 6.9% on DM basis.…”

“…In dairy thermal processes, because of the presence of reducing sugars (lactose and glucose) and amino compounds (including amino acids and proteins), HMF and methylimidazoles are eventually produced via Maillard reaction (Moon and Shibamoto, 2011;Guan et al, 2012b). In addition, methylimidazoles can be introduced into the milk of cows fed ammoniated forage as a result of the interaction of ammonia with reducing sugars (Waagepetersen and Thomsen, 1977). Recently, some studies have reported that potential toxic, mutagenic, and carcinogenic effects were observed after dietary exposure to HMF (Guan et al, 2012c).…”

A simultaneous analysis of methylimidazoles, reducing sugars, and 5-hydroxymethyl-2-furaldehyde in the Maillard reaction was improved by use of an amino trap column. Analysis was carried out by using high-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD) coupled with an amino trap column. The amino trap column was a useful tool to improve the separation of methylimidazoles, reducing sugars, and 5-hydroxymethyl-2-furaldehyde. This technique is useful for simultaneous analysis of methylimidazoles, reducing sugars, and 5-hydroxymethyl-2-furaldehyde in risk assessment for dairy products.
