A habitat-simulating medium was developed for the enumeration and isolation of bacteria from a swine waste digester. A roll tube medium with growth factors for strict anaerobes from previously studied anaerobic ecosystems was used to evaluate the effects of deletion, addition, or level of digester fluid, digester fluid treated with acid or base, rumen fluid, fecal extract, anaerobic pit extract...

Abstract. The aim of this work is to investigate the relationship between indicators cicatricial digestion and linearity cows. Methods. research was carried out in breeding enterprises Sverdlovsk region on livestock Ural-type Cicatricial fluid collected with an oropharyngeal rubber probe, a wooden yaw also used. content assessed at Chelyabinsk Interregional Veterinary Laboratory. pH value deter...

Fungi which grow in stored commodities are xerophilic, that is, capable of growing at reduced water activity (aw). Some xerophilic fungi either will not grow or grow only very slowly at the high aw values of media traditionally used to enumerate yeasts and moulds in foods and feedstuffs. Populations of xerophiles may therefore be underestimated or go undetected if the media and methods normally...

The objective of this study was to investigate the effect of carbohydrate source and cottonseed meal level in the concentrate on feed intake, nutrient digestibility, rumen fermentation and microbial protein synthesis in swamp buffaloes. Four, 4-yr old rumen fistulated swamp buffaloes were randomly assigned to receive four dietary treatments according to a 2×2 factorial arrangement in a 4×4 Lati...

Three wild-type white rot fungi and two cellulase-less mutants developed from Phanerochaete chrysosporium K-3 (formerly Sporotrichum pulverulentum) were tested for their ability to delignify grass cell walls and improve biodegradation by rumen microorganisms. Fungal-treated and control stems of Bermuda grass were analyzed for their content of ester- and ether-linked aromatics by using alkali ex...

The ruminal microbiome, comprising large numbers of bacteria, ciliate protozoa, archaea and fungi, responds to diet and dietary additives in a complex way. The aim of this study was to investigate the benefits of increasing the depth of the community analysis in describing and explaining responses to dietary changes. Quantitative PCR, ssu rRNA amplicon based taxa composition, diversity and co-o...
