Effects of barley volume-weight and processing method on feedlot performance of finishing steers. Can. J. Anim. Barley of three different volume-weights (VW) (light, 47.8; medium, 55.6; heavy, 66.6 kg hL ') was subjected to two processing treatments (DR, dry rolled; SF, steam flaked) and fedto 792 yearling steers (avg. body weight 332kg) at a level of 85% of the dietary dry matter (DM) in combination with barley srlage (10.75% of DM) and mineral-vitamin premix (4.25% of DM) during the finishing period. No significant two-and three-way interactions were observed for any of the traits studied. Average daily gain (ADG) of cattle fed SF and DR diets was similar (P > 0.05) except during the first 27 d of the trial in which the SF steers gained 9.4% faster (P < 0.05) than the DR steers. Dry matter intake (DMI) of steers fed SF barley tended to be higher (P < 0.10) in period one and in period three than for those fed DR barley but was similar for both processing groups in periods two and four and overall. Dry matter consumed per unit of liveweight gain (DM/G) was similar for the two processing treatments during all periods and overall although it tended (P < 0.10) to be lower for the DR steers during period two. Volume-weight had no effect (P > 0.05) on ADG or DMI. Overall

“…In agreement with the current study, Grimson et al (1987) reported that the effects of steam-processing barley grain compared to dry-rolling were confined to the early stages of feeding and were reflected in increased LWG during the first 27 days but not in subsequent periods. In other previous studies, Hale et al (1966) showed somewhat longer-term effects of steam-processing barley on LWG (7.6% higher than DR) presumably due to 9% higher DMI. Later Hale (1973Hale ( , 1980 concluded that the increases in DMI and LWG due to steam-processing compared to dry-rolling or grinding of barley are usually not accompanied by improvements in feed conversion.…”

This study was conducted to determine the effects of barley processing method on the performance of pre-weaned dairy calves. The experiment comprised 12 bull calves which were offered either dry-rolled (DR) or dry-rolled plus steamprocessed (DRSP) barley. During the pre-weaning period (from 14 to 56 days of age) the dry matter and energy intakes of the DRSP calves were higher than those of the DR calves (pB0.1). During weaning (56Á70 days) and on average over the whole experiment (14Á70 days) there were no differences in intake. The weight gain of the DRSP calves was 32% higher than that of the DR calves during the pre-weaning period (pB0.05). During weaning the DR calves grew 33% faster than the DRSP calves (p B0.1). There was no difference in gain on average over the whole experiment. This study indicates no need for steam-processing of barley offered to dairy calves.

“…For barley, for example, which is an important grain used in the feeding of ruminants, about 6% of 209 tested spring varieties were found to have a very high RS content (11%), whereas 7% showed a very low RS content of <1% [62]. As early as in the mid-1960s, cereal-processing technologies with barley, maize, and sorghum were developed [63]. Mechanical or thermal treatments, such as steam flaking, roasting, popping, reconstituting, or micronizing, were performed in order to enhance the starch digestibility in the rumen and to increase the feed utilization efficiency [17].…”

Peculiarities of Enhancing Resistant Starch in Ruminants Using Chemical Methods: Opportunities and Challenges

High-producing ruminants are fed high amounts of cereal grains, at the expense of dietary fiber, to meet their high energy demands. Grains consist mainly of starch, which is easily degraded in the rumen by microbial glycosidases, providing energy for rapid growth of rumen microbes and short-chain fatty acids (SCFA) as the main energy source for the host. Yet, low dietary fiber contents and the rapid accumulation of SCFA lead to rumen disorders in cattle. The chemical processing of grains has become increasingly important to confer their starch resistances against rumen microbial glycosidases, hence generating ruminally resistant starch (RRS). In ruminants, unlike monogastric species, the strategy of enhancing resistant starch is useful, not only in lowering the amount of carbohydrate substrates available for digestion in the upper gut sections, but also in enhancing the net hepatic glucose supply, which can be utilized by the host more efficiently than the hepatic gluconeogenesis of SCFA. The use of chemical methods to enhance the RRS of grains and the feeding of RRS face challenges in the practice; therefore, the present article attempts to summarize the most important achievements in the chemical processing methods used to generate RRS, and review advantages and challenges of feeding RRS to ruminants.
