Special Issue Information

Dear Colleagues,

It has been 57 years since Robert E. Hungate’s 1966 book The Rumen and Its Microbes was first published. Recently, rumen research has been advancing, and modern technology is being used. The rumen is a naturally fermentative anaerobic system that can be manipulated primarily by altering the composition of rumen microflora. The rumen ecosystem is a prominent example of host–microorganism interaction. The host feeds on plant fibers, which can only be destroyed by a complicated metabolic cascade encoded only in rumen-associated microorganisms. The rumen consists of a wide range of microbes, including prokaryotic and eukaryotic, that enable the animal to use plant fiber and change NPN into microbial protein in order to supply amino acids and energy. These cascades provide the hosting animal with basic metabolites. In fact, the synthesis of volatile fatty acids (VFA) by rumen microbes can supply up to 70% of a ruminant's energy needs.

Rumen fermentation is particularly well suited due to its relatively constant and continuous nature, as well as the extremely rapid rates of organic matter conversion. Before enzymes digest in the lower intestine, all ruminant foods undergo fermentative activity in the rumen. Thus, the degree and kind of feedstuff modification impact the productive performance of the host. Rumen microbial ecology and metabolism studies are largely concerned with the interactions between the animal, the microbes present, the feed supply, and the rumen by-products of digestion. Molecular techniques have been used to study the dynamics of rumen microorganisms. The interactions of the typical microbe with the animal can be altered to improve ruminant animal nutrition use efficiency.

Furthermore, ruminal methanogens can produce methane during enteric fermentation. Rumen methane emissions account for approximately 17% of global methane emissions, which are of concern globally due to their contribution to greenhouse gas buildup in the environment, as well as their waste of supplied energy for the ruminant. Approximately 2–12% of the ingested feed energy is also lost as methane. Many studies have been conducted on ruminant methane mitigation strategies.

Thus, manipulations of rumen fermentation to improve productivity and health are new challenges that require further investigation.

The goal of this Special Issue is to publish both recent advances in research and review papers on improving rumen fermentation efficiency in ruminants. Ruminant nutrition reviews and research papers are also of interest. If you want to submit a review paper, please contact the editors first to discuss the topic's relevance before submitting the manuscript.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fermentation is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The objective of this experiment was to investigate the effects of 5,6-dimethylbenzimidazole (5,6-DMB) and cobalt (Co) on the ruminal vitamin B12 synthesis and fermentation parameters of sheep under high concentrate conditions. Twenty-four Kazakh rams (body weight = 39.23 ± 2.61 kg and 8 months old) fitted with permanent ruminal fistulas were randomly divided into four groups with six rams in each group. The control (CON) group was fed a basal ration with a concentrate-to-roughage ratio of 70:30, and the experimental groups (T60, T75 and T90) were fed a basal diet with 60 mg 5,6-DMB+ 0.25 mg Co, 75 mg 5,6-DMB+ 0.5 mg Co and 90 mg 5,6-DMB+ 0.75 mg Co supplied to each kilogram of basal diet, respectively. The experiment lasted for 26 days, with the first 14 days being an adaptation period to allow the sheep to adapt to the diet type and environment, and the second 12 days being a sample period. On 0, 7 and 12 d of the sample period, all sheep were weighed before the morning feed. Rumen fluid samples were collected from all sheep on the last 4 days of the sample period. The results showed that the ruminal vitamin B12 content was higher in trial groups than that of the CON group at 3 h after feeding (p < 0.05). Rumen pH was higher in trial groups than in the CON group at 1, 3 and 5 h after feeding (p < 0.05). The concentration of ruminal ammonia-N was significantly increased in trial groups when compared to the CON group (p < 0.05) at 1 and 3 h after feeding. At 1 and 3 h after feeding, the concentration of propionate in trial groups was higher than that in the CON group (p < 0.05). The rumen microbial protein content reached the highest value at 3 h after feeding, and all trial groups were higher than the CON group (p < 0.05). Thus, the supplementation of 5,6-DMB and Co increased vitamin B12, propionate, ammonia-N and microbial protein contents and pH in the rumen of sheep, and the best results were obtained by the amounts of 75 mg/kg 5,6-DMB and 0.5 mg/kg Co, respectively.

The present study investigates the effect of 50 mL AMCB taken daily as a dietary supplement on the rumen fermentation, microbiota, and production performance of 40 Holstein dairy cows in the transition period with 2.76 ± 0.48 parity and 650 ± 25 kg body weight. AMCB supplementation stabilized rumen pH, improved rumen microbiota richness and partial probiotic colonization, and considerably increased dry matter intake, milk production, protein content, and yield. Moreover, after calving, AMCB supplementation considerably reduced the serum blood urea nitrogen, malondialdehyde, hydrogen peroxide, alanine aminotransferase, and aspartate transaminase levels and increased the serum immunoglobulin G and A levels. The results indicated that AMCB dietary supplementation improved postpartum dry matter intake, production performance, partial immune function, antioxidant capacity, and rumen microbiota richness in Holstein dairy cows in the transition period. AMC is an excellent candidate for use as a rumen buffer. Full article
