This study was conducted to investigate the effects of eucalyptus (E. Camaldulensis) crude oils (EuO) supplementation on voluntary feed intake and rumen fermentation characteristics in swamp buffaloes. Four rumen fistulated swamp buffaloes, body weight (BW) of 420±15.0 kg, were randomly assigned according to a 2×2 factorial arrangement in a 4×4 Latin square design. The dietary treatments were u...

This study aimed to investigate the effects of storage duration and temperature on the characteristics of wet brewers grains (WBG) as feeds for ruminant animals. Four storage temperatures (5°C, 15°C, 25°C, and 35°C) and four durations (0, 1, 2, and 3 d) were arranged in a 4×4 factorial design. Surface spoilage, chemical composition and microorganism density were analyzed. An in vitro gas test w...

The process called biohydrogenation occurs mainly in ruminant animals and during it, unsaturated fatty acids, and particularly poly-unsaturated ones (linoleic and linolenic) coverts to a saturated form of stearic acid. For many years, the beneficial effects of biohydrogenation intermediate fatty acids like cis-9 trans-11 linoleic acid, the main natural isomer of conjugated linoleic acids (CLA),...

The effect on methanogens attached to the surface of rumen ciliate protozoa by the addition of plant extracts (pine needles and ginkgo leaves) was studied with particular reference to their effectiveness for decreasing methane emission. The plant extracts (pine needles and ginkgo leaves) were added to an in vitro fermentation incubated with rumen fluid. The microbial population including bacter...

Establishing the phylogeny of fungi and protists often has proved difficult owing to the simple morphologies and convergent characters in these organisms. We used DNA sequences of nuclear small-subunit ribosomal RNA genes to determine phylogenetic relationships among three major classes of organisms considered to be fungi--Basidiomycetes, Ascomycetes and Chytridiomycetes--and to assess the taxo...

Hydrolysis and dehydration reactions of carbohydrates, which are used as energy raw materials by all living things in nature, controlled Carbohydrate Active Enzyme (CAZy) systems. These enzymes also different industrial areas today. There types microorganisms that have the CAZy system sector. Apart from current organisms, there rumen fungi within group candidate with system. It has been reporte...

Rumen microbiota has been previously related to phenotypic complex traits of relevance in dairy cattle. The joint analysis the host's genetic background and its can be statistically modelled using similarity matrices between microorganism communities different hosts. Microbiota relationship (K) enable considering whole cumbersome interrelations taxa, rather than analyzing single taxa one at tim...

It has been known for decades that microbial fermentation within the rumen is critical to postnatal rumen epithelial growth and maturation in ruminants, but the underlying mechanism is largely unknown. In this study, we determined the effect of rumen fluid, which should contain all products from rumen fermentation, on growth of rumen epithelial cells in vitro. Addition of 10% rumen fluid from c...

Hedqvist, H. 2004. Metabolism of soluble proteins by rumen microorganism and the influence of condensed tannins on nitrogen solubility and degradation. Doctoral thesis. ISSN 1401-6249, ISBN 91-576-6780-2. The amino acid requirements of ruminants are met by two sources; microbes leaving the rumen and dietary protein escaping fermentation in the rumen. Much ruminant research has therefore focused...
