“…Probiotics have the potential to enhance intestinal health by stimulating the development of a balanced microbiota with a predominance of beneficial bacteria, preventing the colonization of enteropathogens, increasing digestive capacity and improving mucosal immunity (Uyeno et al, 2015). Furthermore, demonstrated benefits of probiotic administration include increased body weight gain and reduced incidence of diarrhea (Timmerman et al, 2005;Goto et al, 2016).…”

Gut microbial colonization and establishment are vital to ruminant health and production. This review article focuses on current knowledge and methods used to understand and manipulate the gut microbial community in ruminant animals, with a special focus on probiotics treatment. This review highlights the most promising of studies in this area, including gut microbial colonization and establishment, effect of gastrointestinal tract microbial community on host mucosal innate immune function, impact of feeding strategies on gut microbial community, current probiotic treatments in ruminants, methods to manipulate the gut microbiota and associated antimicrobial compounds, and models and cell lines used in understanding the host immune response to probiotic treatments. As a lot of work in this area is done in humans and mice, this review article also includes up-to-date knowledge from relevant studies in human and mouse models. This review is a useful resource for scientists working in the areas of ruminant nutrition and health, and to researchers investigating the microbial ecology and its relation to animal health.

“…Nowadays, SARA is commonly defined as a pH <5.6 for >3 hr/day (Plaizier, Krause, Gozho, & McBride, 2008), or a pH <5.8 for >5.24 hr/day (Zebeli et al., 2008). A decrease in ruminal pH causes changes in the microbial community and subsequent alterations in the fermentation pattern (Goto et al., 2016; Khafipour, Krause, & Plaizier, 2009b).…”

“…Ruminal fluids were collected from adjacent to the pH sensor at 13:00 on the last day of each period. These samples were immediately filtered through two layers of cheesecloth, and treated for further analyzes as reported previously [5]. Briefly, the VFAs were quantified with gas chromatography (Hitachi-163, Hitachi, Tokyo, Japan), and the ruminal LPS activity was measured using a kinetic colorimetric method with Limulus amebocyte lysate (Pyrochrome; Seikagaku, Tokyo, Japan).…”

This study evaluated the effects of increasing the proportion of concentrate in the diet on the rumen pH and bacterial community in Japanese Black beef cattle at different fattening stages. Six rumen-cannulated beef cattle were studied in the middle (Mid group, n=3, age 21–22 months) and late (Late group, n=3, age 31 months) fattening stages. The cattle were fed rice straw with control (CON period) or high-concentrate (HC period) diets for 14 consecutive days in each period. Rumen pH was measured continuously and the rumen fluids were collected on the last day of each period. The 24-hr mean and minimum rumen pH in the Mid group were significantly ( P <0.05) lower during the HC period compared with the CON period, whereas those in the Late group were continuously low during both periods. In the Late group, the ruminal volatile fatty acid and lactic acid concentrations were significantly ( P <0.05) higher during the HC period. During the HC period, the proportions of Prevotella and Caloramator were significantly ( P <0.05) higher and lower, respectively, in the Mid group. From these findings, significant changes in the rumen pH and bacterial community induced by dietary changes were mainly observed in the Mid group. Therefore, the ruminal fermentative function in response to a higher concentrate diet might adapt differently in Japanese Black beef cattle at the two different fattening stages.
