“…For absolute quantification of each microbe, a standard curve obtains with a 10-fold dilution of plasmids containing the respective target gene sequence. For absolute quantification of each microorganism, a standard curve obtained by a plasmid containing each target gene sequence with 10-fold serial dilutions was used, and all the detailed manufacturing processes of each microbe plasmid were performed according to Kim et al [ 34 ] and Hamid et al [ 35 ]. All the reactions were performed in triplicate.…”

Ruminants produce large amounts of methane as part of their normal digestive processes. Recently, feed additives were shown to inhibit the microorganisms that produce methane in the rumen, consequently reducing methane emissions. The objective of this study was to evaluate the dose–response effect of Phyllostachys nigra var. henonis (PHN) and Sasa borealis supplementation on in vitro rumen fermentation, methane, and carbon dioxide production, and the microbial population. An in vitro batch culture system was used, incubated without bamboo leaves (control) or with bamboo leaves (0.3, 0.6, and 0.9 g/L). After 48 h, total gas, methane, and carbon dioxide production decreased linearly with an increasing dose of bamboo leaves supplementation. The total volatile fatty acid, acetate, and acetate-to-propionate ratio were affected quadratically with increasing doses of bamboo leaves supplementation. In addition, propionate decreased linearly. Butyrate was increased linearly with increasing doses of PHN supplementation. The absolute values of total bacteria and methanogenic archaea decreased linearly and quadratically with an increasing dose of PHN treatment after 48 h. These results show that bamboo leaves supplementation can reduce methane production by directly affecting methanogenic archaea, depressing the metabolism of methanogenic microbes, or transforming the composition of the methanogenic community. These results need to be validated using in vivo feeding trials before implementation.

“…rapid growth of ruminants, but early weaning can induce various stresses in young ruminants, which can cause growth retardation and suppression of the immune system [37,38]. Therefore, it is known that early settlement of microorganisms can be induced by transplanting rumen fluid to young ruminants for successful early weaning and rumen development, and digestive disorders of ruminants can be treated by transplanting rumen fluid [39,40].…”

“…Therefore, the nutrients, especially fiber carbohydrates in RGB, may be more favorable for degradation than those in timothy hay, even though their chemical compositions are similar. RGB also contains abundant bioactive compounds that can modulate rumen microbial fermentation [ 30 ], thereby higher nutrient degradation in GINSENG might be possible. Contrary to our results, Kim et al [ 31 ] reported that the replacement of alfalfa hay (0% to 15%) with ginseng meal did not result in increased IVDMD.…”

“…However, the total VFA concentration between treatments did not differ in CON. Hamid et al [ 30 ] reported that the IVDMD and aNDF digestibility of corn gluten feed and RGB were similar, but the total VFA production was significantly lower in RGB. It has also been reported that the pH of RGB is significantly lower than that of corn gluten feed.…”

The objective of this study was to evaluate the effects of dietary supplementation with red ginseng byproduct (RGB) on rumen fermentation, growth performance, blood metabolites, and mRNA expression of heat shock proteins (HSP) in fattening Hanwoo steers under heat stress. Two experimental total mixed rations (TMR) were prepared: (1) a TMR meeting the requirement of fattening beef having an average daily gain (ADG) 0.8 kg/day (CON) and (2) a TMR that included 2% RGB on a dry matter (DM) basis (GINSENG). In vitro rumen fermentation and in vivo growth experiments were conducted using two experimental diets. A total of 22 Hanwoo steers were distributed to two treatments (CON vs. GINSENG) in a completely randomized block design according to body weight (BW). The experiment was conducted during the summer season for five weeks. The final BW, ADG, DM intake, and feed conversion ratio did not differ between treatments in the growth trial. In the mRNA expression results, only HSP 90 showed an increasing tendency in the GINSENG group. The use of 2%DM RGB did not improve the growth performance or alleviate heat stress in fattening Hanwoo steers during the summer season.
