“…starch sources in the feed could decrease the DMI [24,25], we observed no difference in the DMI, even though the pro portion of starch was higher in the rice grains than in the corn grains used in the present study (rice starch, 78.1% DM; corn starch, 71.5% DM, data not shown). This is consistent with the previous studies that have reported that the DMI did not exhibit significant differences in dairy cattle when using rice grains instead of corn grains in the feed containing approxi mately 31% DM [3] and 36% DM [22]. Studies substituting corn grains with rice grains have been carried out not only in ruminants but also in monogastric ani mals [2628].…”

Objective: This study was realized to evaluate the nutritional value of rice grains as a replace ment for corn grains in the diet of growing Hanwoo steers. Methods: Two experimental diets were prepared: i) Corn total mixed ration (TMR) consisting of 20% corn grains and ii) Rice TMR consisting of 20% rice grains, in a dry matter (DM) basis. These treatments were used for in vitro rumen fermentation and in vivo growth trials. In the rumen fermentation experiment, the in vitro DM digestibility (IVDMD), in vitro crude protein digestibility (IVCPD), in vitro neutral detergent fiber digestibility, pH, ammo nia nitrogen, and volatile fatty acids (VFA) were estimated at 48 h, and the gas production was measured at 3, 6, 12, 24, and 48 h. Twenty four growing Hanwoo steers (9 months old; body weight [BW]: 259±13 kg) were randomly divided into two treatment groups and the BW, dry matter intake (DMI), average daily gain (ADG), and feed conversion ratio (FCR) were measured. Results: The in vitro experiment showed that the IVDMD, IVCPD, and VFA production of the Rice TMR were higher than those of the Corn TMR (p<0.05). The growth trial showed no differences (p>0.05) in the final BW, ADG, DMI, and FCR between the two TMRs. Conclusion: The use of rice grains instead of corn grains did not exhibit any negative effects on the rumen fermentation or growth performance, thereby rice grains with a DM of less than 20% could be used as a starch source in the diet of growing steers.

“…However, there is a limited information on the application of PR in the diet of sheep. Grain of brown rice was reported to be an alternative energy feedstuff that can be used in dairy cow diets, totally replacing corn grain, without any negative effect on the animal health, feed intake, digestibility, milk yield and composition [30]. As the hull part comprised of small amounts of starch and mostly non-starch polysaccharides such as cellulose and hemicellulose, dehulling is the best option to supply the optimal nutritive value for cattle.…”

The objective of this study was to evaluate the nutritive value of polished rice (PR) vs unpolished rice (UPR) as a potential feedstuff for sheep in order to use as a replacer to corn in sheep diet, and as well as to present the application in the formulation of cattle diet. Six corriedale ewe were randomly assigned to each treatment. UPR and PR were provided as a dietary treatment together with timothy grass as a basal diet in a crossover design for two period with 15-d duration for each period. The ratio of experimental and basal feeds were 33.3% and 66.7%, respectively. The differences in the total digestible nutrient (TDN) contents between sheep and cattle was determined according to the references. The number of data collected sheep and cattle was 9 and 17, respectively. The PR showed higher nutrients digestibility than UPR. Similarly, higher TDN content was observed PR than UPR (p < 0.05). As a result, the replacement of corn in the formulate feed with UPR and PR feed rice could be possible with the ratio of 91.2% and 100.0%, respectively. The result of comparation the TDN contents of UPR and PR in sheep and cattle, the PR has no difference in the nutritive value which suggests the applicability of the results of sheep to cattle. On the other hand, UPR has known to have different nutritive value between sheep and cattle, so caution should be taken when preparing formula feeds for cattle.

“…Nevertheless, in Korean early fattening stage steering diets for higher beef marbling, there are no findings regarding the use of rice as a corn replacement up to 33% DM. Rice as an alternative to corn for energy-rich diets can be essential for integrated crop and livestock production systems [10], balancing and boosting Hanwoo cattle productivity. Including energy-rich grains in fattening TMR diets can affect productivity and rumen fermentation characteristics [2].…”

Substitution effects of rice for corn grain in total mixed ration on rumen fermentation characteristics and microbial community in vitro

This study determined the substitution effects of rice for corn as the main grain source in a total mixed ration (TMR). In vitro rumen fermentation characteristics and microbes were assessed using two experimental diets. Diets included 33% dry matter (DM) of either corn (Corn TMR) or rice grains (Rice TMR). In a 48-h in vitro incubation, DM digestibility (IVDMD), neutral detergent fiber degradability (IVNDFD), crude protein digestibility (IVCPD), volatile fatty acids (VFAs), pH and ammonia nitrogen (NH 3-N) were estimated. Gas production has been calculated at 3, 6, 12, 24 and 48 h. Our results indicate that the gas production, VFAs, IVDMD, and IVNDFD of Rice TMR were higher than those of Corn TMR (p < 0.05). Ruminal pH and total fungi were significantly higher in Corn TMR (p < 0.05) than in Rice TMR; however, NH 3-N and IVCPD were not affected by treatment type. In conclusion, substituting rice for corn at 33% DM in TMR appears to have no negative effects on in vitro rumen fermentation characteristics. Therefore, rice grains are an appropriate alternative energy source in early fattening stage diets of beef cattle.
