Britt., an annual herbaceous plant, has antibacterial, anti-inflammation, and antioxidant properties. To understand the effects of P. frutescens leaf on the ruminal microbial ecology of cattle, Illumina MiSeq 16S rRNA sequencing technology was used. Fourteen cows were used in a randomized complete block design trial. Two diets were fed to these cattle: a control diet (CON); and CON supplemented with 300 g/d P. frutescens leaf (PFL) per cow. Ruminal fluid was sampled at the end of the experiment for microbial DNA extraction. Overall, our findings revealed that supplementation with PFL could increase ruminal fluid pH value. The ruminal bacterial community of cattle was dominated by Bacteroidetes, Firmicutes, and Proteobacteria. The addition of PFL had a positive effect on Firmicutes, Actinobacteria, and Spirochaetes, but had no effect on Bacteroidetes and Proteobacteria compared with the CON. The supplementation with PFL significantly increased the abundance of Marvinbryantia, Acetitomaculum, Ruminococcus gauvreauii, Eubacterium coprostanoligenes, Selenomonas_1, Pseudoscardovia, norank_f__Muribaculaceae, and Sharpea, and decreased the abundance of Treponema_2 compared to CON. Eubacterium coprostanoligenes, and norank_f__Muribaculaceae were positively correlated with ruminal pH value. It was found that norank_f__Muribaculaceae and Acetitomaculum were positively correlated with milk yield, indicating that these different genera are PFL associated bacteria.

  • A Microbiologist's View on Improving Nutrient Utilization in Ruminants
    A Microbiologist’s View on Improving Nutrient Utilization in Ruminants T. G. Nagaraja1 College of Veterinary Medicine, Kansas State University, Introduction Ruminants, particularly cattle, sheep, and goats, are important production animals for food to humans worldwide. Their importance comes from their unique ability to convert, because of foregut microbial fermentation, fiber-based feeds with or without grains, into high quality, protein-rich products like milk and meat. The rumen, the first compartment of the complex stomach, is inhabited by a multitude of microbes that work in concert to breakdown feeds to produce energy (volatile fatty acids; VFA), protein (microbial cells) and other nutrients like vitamins (microbial cells) to the host. The production of VFA, mainly from carbohydrates. is central to the ruminal fermentation because the process provides energy (ATP) for microbial growth, which serves as the major source of protein to the host, but also provides the animal with the precursors necessary to generate energy (mainly acetate), glucose (mainly propionate), and lipid (mainly acetate and butyrate). The fermentation of nitrogenous compounds is also an integral process because it provides the molecules necessary to build microbial cell protein. In addition to the importance of the rumen microbial function to the host nutrition and food production, rumen microbes and their enzymes are also of considerable interest to the biofuels and biotechnology industries (Hess et al., 2011). Despite the tremendous importance, rumen remains an under investigated, hence, under-characterized, microbial ecosystem. At one time, rumen was the most extensively investigated anaerobic ecosystem. In the past 10 to 12 years, human gut microbial studies have far outpaced rumen microbiology studies.

THE EFFECT OF EARLY LIFE NUTRITION ON RUMEN MICROBIAL COMMUNITY DEVELOPMENT AND IMPACT ON LIFETIME PERFORMANCE IN RUMINANTS A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy In Veterinary Sciences At Massey University Palmerston North New Zealand Omar Cristobal Carballo 2019 Abstract Manipulation of the rumen microbiota in adult ruminants has been intended to improve animal performance and decrease greenhouse gas emissions, but results have only shown a short- or non-lasting effect after intervention. Changes in the ruminal microbiota during rumen development have recently shown promising results in the short-term. Therefore, the purpose of the present body of work was to determine how dietary management and chemical interventions, during rumen development, modify the ruminal microbial community composition, and whether these changes affect rumen fermentation and development, and consequently, performance in the young ruminants. The objectives of this thesis were to: (i) evaluate the impact of early weaning on rumen development and function in artificially-reared lambs; (ii) characterize the impact of early weaning in lambs on the rumen microbiota in the first 16 weeks of life and examine the relationships between rumen microbiota composition and rumen fermentation profiles, rumen development and blood metabolites; (iii) assess whether contrasting feeding regimes in the first 7 months of life lead to an imprint in the rumen microbial community structure, fermentation profiles and methane emissions in the rumen of calves; (iv) and evaluate the effect of methane inhibitors on the rumen microbial community composition, fermentation pathways, and gas emissions in calves.

Attwood1* Abstract Background: Enteric fermentation by farmed ruminant animals is a major source of methane and constitutes the second largest anthropogenic contributor to global warming. Reducing methane emissions from ruminants is needed to ensure sustainable animal production in the future. Methane yield varies naturally in sheep and is a heritable trait that can be used to select animals that yield less methane per unit of feed eaten. We previously demonstrated elevated expression of hydrogenotrophic methanogenesis pathway genes of methanogenic archaea in the rumens of high methane yield (HMY) sheep compared to their low methane yield (LMY) counterparts. Methane production in the rumen is strongly connected to microbial hydrogen production through fermentation processes. In this study, we investigate the contribution that rumen bacteria make to methane yield phenotypes in sheep.

Abstract: This study investigated the effects of dandelion on the ruminal metabolome and micro- biome in lactating dairy cows. A total of 12 mid-lactation dairy cows were selected and randomly classified into two groups, supplementing dandelion with 0 (CON) and 200 g/d per cow (DAN) above basal diet, respectively. Rumen fluid samples were collected in the last week of the trial for micro- biome and metabolome analysis. The results showed that supplementation of DAN increased the con- centrations of ammonia nitrogen, acetate, and butyrate significantly. The rumen bacterial community was significantly changed in the DAN group, with Bacterioidetes, Firmicutes, and Proteobacteria be- ing the main ruminal bacterial phyla.
