“…Corresponded with the increased total VFA concentration and the higher molar proportion of propionate, the pH of TRT was significantly decreased compared with CON. Previous studies also reported that increases in total VFA concentrations and the molar proportion of propionate were associated with the decrease in pH due to containing more soluble nonstructural carbohydrates in diets ( Penner and Oba, 2009 ; Song et al, 2018 ). Total gas production and CH 4 production from TRT were both higher than that from CON, but the increases were both statistically insignificant.…”

Steam explosion is an environment-friendly pretreatment method to improve the subsequent hydrolysis process of lignocellulosic biomass. Steam explosion pretreatment improved ruminal fermentation and changed fermentation pattern of corn stover during ruminal fermentation in vitro . The study gave a comprehensive insight into how stream explosion pretreatment shifted archaeal and bacterial community structure to change ruminal fermentation in vitro of corn stover. Results showed that steam explosion pretreatment dramatically improved the apparent disappearance of dry matter (DM), neutral detergent fiber (NDF), and acid detergent fiber (ADF). Steam explosion pretreatment significantly increased the molar proportion of propionate and decreased the ratio of acetate to propionate. At archaeal level, steam explosion pretreatment significantly increased the relative abundance of Methanobrevibacter , which can effectively remove metabolic hydrogen to keep the fermentation continuing. At bacterial level, the shift in fermentation was achieved by increasing the relative abundance of cellulolytic bacteria and propionate-related bacteria, including Spirochaetes, Elusimicrobia, Fibrobacteres, Prevotella , Treponema , Ruminococcus , and Fibrobacter .

“…After a long-term adaptation and evolutionary process, rumen microbiota and the host have developed a symbiotic relationship to maintain the host's health and productivity [6]. There are many factors, such as species, age, diet, feeding, management, etc., influencing rumen environment [7][8][9][10]. The forage to concentrate ratio is a major factor, which affects rumen bacteria.…”

The study was conducted to investigate the effects of dietary NFC/NDF ratio change on rumen bacteria in sheep. Twelve Karakul sheep were assigned randomly into four groups fed with four dietary NFC/NDF ratios of 0.54, 0.96, 1.37, and 1.90 and they were assigned into groups 1, 2, 3, and 4, respectively. The experiment was divided into four periods: I (1–18 d), II (19–36 d), III (37–54 d), and IV (55–72 d). In each period, the first 15 d were used for adaption, and then rumen fluid was collected for 3 d from each sheep before morning feeding. The fluid was analyzed with three generations of full-length amplifiers sequencing. Results showed that the bacterial diversity of group 4 was decreased in period III and IV. At the phylum level, Bacteroidetes (37–60%) and Firmicutes (26–51%) were the most dominant bacteria over the four periods. The relative abundance of Bacteroidetes, Firmicutes, Tenericutes, and Spirochaete changed with dietary NFC/NDF ratio change over the four periods, but there was no difference among groups over the four periods (p > 0.05). At the genus level, unidentified-Lachnospiraceae was the dominant genus, and its relative abundance in group 3 was high during the period I and III (p < 0.05). The relative abundance of Mycoplasma in group 4 was high in the period I and II (p < 0.05). The relative abundance of Succiniclasticum was high in group 2 of period II (p < 0.05). At the species level, the relative abundance of Butyrivibrio-fibrisolvens was found to be high in group 3 during periods I and III (p < 0.05). The main semi-cellulose-degrading bacteria and starch-degrading bacteria were low, and there was no significant difference among groups over four periods (p > 0.05). Taken together, the dietary NFC/NDF ratio of 1.90 decreased the diversity of bacteria as a period changed from I to IV. While the main phylum bacteria didn’t change, their relative abundance changed with the dietary NFC/NDF ratio change over the four periods. The most prevalent genus was unidentified-Lachnospiraceae, and its relative abundance was higher in dietary NFC/NDF ratio of 1.37 than other groups. Similarly, the main cellulose-degrading species was higher in the treatment of dietary NFC/NDF ratio of 1.37 than other groups.

“…Body performance can be improved by modulating the body system, increasing the feed intake, increasing or alleviating ruminal acidosis, improving digestibility, VFA profiles, and metabolites (Table 1). Body performance can be improved by improving animal energy balance through supplements and/or replacement of plant-based by-product, tomato silage with dietary lipids, sunflower oil [31], essential oil-cobalt [8], exogenous fibrolytic enzyme [36], and dietary cations and anions [37]. By partially replacing conventional forage with tomato silage plus sunflower oil [31], the body performance of dairy goats during mid-lactation was improved by increasing their body weight gain without compromising milk production and composition.…”

“…By partially replacing conventional forage with tomato silage plus sunflower oil [31], the body performance of dairy goats during mid-lactation was improved by increasing their body weight gain without compromising milk production and composition. Diets with a high non-fiber carbohydrate to neutral detergent fiber ratio and exogenous fibrolytic enzyme improved growth performance in Lezhi black goats by improving the average daily gain, feed conversion ratio, and nutrient utilization [36]. This could be due to increased microbial protein supply to the small intestine.…”

“…Cereal grains treated with organic acids increased ruminal resistant starch and relieved the risk of ruminal acidosis as well as reducing the inflammatory response [43]. In addition, fungal ( Lentinus sajor-caju )-treated oil palm fronds [44], spent mushroom ( Cordyceps militaris ) [45], Moringa oleifera [6,24], lemongrass [23], rosemary [23], flaxseed oil [5], exogenous fibrolytic enzyme (cellulase) [28], and exogenous fibrolytic enzyme [36] were used to improve digestion in goats.…”

Recent development of novel techniques in systems biology have been used to improve and manipulate the rumen microbial ecosystem and gain a deeper understanding of its physiological and microbiological interactions and relationships. This provided a deeper insight and understanding of the relationship and interactions between the rumen microbiome and the host animal. New high-throughput techniques have revealed that the dominance of Proteobacteria in the neonatal gut might be derived from the maternal placenta through fetal swallowing of amniotic fluid in utero, which gradually decreases in the reticulum, omasum, and abomasum with increasing age after birth. Multi “omics” technologies have also enhanced rumen fermentation and production efficiency of dairy goats using dietary interventions through greater knowledge of the links between nutrition, metabolism, and the rumen microbiome and their effect in the environment. For example, supplementation of dietary lipid, such as linseed, affects rumen fermentation by favoring the accumulation of α-linolenic acid biohydrogenation with a high correlation to the relative abundance of Fibrobacteriaceae. This provides greater resolution of the interlinkages among nutritional strategies, rumen microbes, and metabolism of the host animal that can set the foundation for new advancements in ruminant nutrition using multi ‘omics’ technologies.
