Good quality protein as an on-farm feed resource has been in great demand to support the productivity of ruminants. A digestion trial using beef cattle crossbreds was conducted to assess the four dietary treatments of Flemingia macrophylla silage (FMS) supplementation at 0, 0.2, 0.4 and 0.6 kg dry matter (DM)/day in a 4 × 4 Latin square design.

Effects of Saccharomyces cerevisiae fermentation products (SCFP) on rumen microbiota were determined in vitro and in vivo under a high and a depressed pH. The in vitro trial determined the effects of Original XPC and NutriTek (Diamond V, Cedar Rapids, IA) at doses of 1.67 and 2.33 g/L, respectively, on the abundances of rumen bacteria under a high pH (> 6.3) and a depressed pH (5.8–6.0) using quantitative PCR (qPCR).

In ruminants, early rumen development is vital for efficient fermentation that converts plant materials to human edible food such as milk and meat. Here, we investigate the extent and functional basis of host-microbial interactions regulating rumen development during the first 6 weeks of life.

The transition from a high forage to a highly fermentable diet can induce digestive disorders in the rumen. To date, the host mechanisms that regulate the adaption to such dietary transition are largely unknown. To understand the molecular mechanisms involved in such phenomena, RNA-sequencing was performed to identify the changes in the transcriptome of ruminal epithelia during gradual transition from a diet containing 0% to 89% grain.

Preweaned rumen development is vital for animal health and efficient fermentation. In this study, we integrated ruminal transcriptomic and metagenomic data to explore the dynamics of rumen functions, microbial colonization, and their functional interactions during the first 8 weeks of life in goats.

Ruminants are herbivorous, forgot fermentors. They are able to acquire nutrients from plant based foods by fermenting it in a specialized stomach having four-compartment stomach. Any sudden change in feeding pattern or an improper feeding regimen is bound to disturb the balance of the various types of microbes, leading to an over population of certain unfavorable microbes and changes in rumen environment that may cause severe problem in animals.

Farmed ruminants form a very large portion of total anthropogenic methane emissions globally. Methanogens present in ruminal flora primarily uses Hydrogen [H] produced during anaerobic carbohydrate fermentation. Ruminal microflora can convert plant fiber unavailable for humans into microbial protein available for absorption for ruminants with biological value 70.

B vitamin supplementation in ruminants is ignored conventionally following an earlier observation that they are synthesized in adequate quantities in the rumen by rumen microbes. Recent researchers reported that major cellulolytic organisms in the rumen had specific requirements for certain B vitamins. Apart from the requirements of the rumen microbes, high producing cattle also require a higher amount of vitamins to maintain their productivity and health. Sub-clinical vitamin deficiencies often go unnoticed due to the lack of proper clinical symptoms.

The present study was carried out to evolve a safe and strategic supplementation to rice gruel by synchronizing nutrient delivery in the rumen for maximum microbial production. Three in vitro trials were conducted to study the rumen fermentation characteristics of nonprotein nitrogen (NPN) and sulphur sources supplementation to rice gruel with basal diet (Bajra x Napier grass, CO4). Urea and diammonium phosphate (DAP) were used as NPN sources, while copper sulphate and sodium sulphate were used as sulphur sources.

The use of yeast culture as a dietary supplement has been suggested as a useful tool to stabilize ruminal fermentation. A study was conducted to explore the scope of rabbit gut transmitted (RGT) S. cerevisiae as probiotic and prebiotic (Synbiotic) by in vitro. The rabbit gut transmitted S. cerevisiae was isolated from the faeces of rabbits as follows.

Ruminant livestock constitute worldwide the most important source of anthropogenic emissions of methane. There are two main factors influencing global warming change, an increase in greenhouse gas emissions and depletion of the ozone layer. Methane is associated with both factors. Ruminants (dairy, beef, goats, and sheep) are the main contributors to CH4 production. Their CH4 production is a natural and inevitable outcome of rumen fermentation.

Urea in diets of ruminants has been investigated to substitute expensive animal and vegetable protein sources for more than a century, and has been widely incorporated in diets of ruminants for many years. Urea is also recycled to the fermentative parts of the gastrointestinal (GI) tracts through saliva or direct secretory flux from blood depending upon the dietary situations. Within the GI tracts, urea is hydrolyzed to ammonia by urease enzymes produced by GI microorganisms and subsequent ammonia utilization serves the synthesis of microbial protein.

The characteristic feature of ruminants is the fermentative nature of their digestion. This feature of their digestive system allows them to survive on high-fibre diets (Leng, 1970). The principal products of fermentation of dietary fibre are short-chain fatty acids....

Rumen fermentation is an exergonic process that converts feedstuffs to short-chain volatile fatty acids (VFA), methane, ammonia and occasionally lactic acid. Some of the free energy is used to drive microbial growth, but heat is also evolved. The efficiency of rumen microbial growth can have a profound effect on animal performance....
