Four sheep were fed an alfalfa hay diet. Rumen content samples were collected three hours after feeding in order to total microorganism population (TP), solid attached population (SAP) and solid attached firmly population (SAFP). Fibrolytic specific activities (xylanase, CMCase and beta-glycosidases) were estimated by the amount of reducing sugars or p-nitrophenol released from the appropriate ...

We studied the effects of a yeast additive used in ruminant nutrition on the establishment of cellulolytic bacteria, on plant cell wall degradation and on digestive functions in the rumen of gnotobiotically-reared lambs. Cellulolytic bacteria inoculated to the lambs tended to become established earlier in the presence of Saccharomyces cerevisiae CNCM I-1077 (SC). In addition, their population w...

The paper studies the effect of additional administration ultrafine particles on cattle rumen microbiome composition. in vitro method was used using ANKOM Daisy II incubator according to a specialized method. Microflora analysis performed MiSeq (Illumina, USA) by new generation sequencing with reagent kit. After detailed structure and composition microbial community contents sampled for differe...

One of the most important aspects livestock is supply essential quantities balanced nutrients manufacture. In several physiological functions nutrients, concerning organisms, protein has an role. Ruminants are not wholly protected amino acids by microflora degradation animal feed sources and maintaining proteins from breakdown in rumen where both high medium yielding ruminant required, they mus...

Introduction Before birth, developing animals are sterile in the womb of their mothers. Upon birth, the digestive tracts of all animals are naturally colonized by a variety of microorganisms. Under healthy and non-stressful conditions, “beneficial” microflora colonizes the rumen and lower gut in a symbiotic relationship with the host. Beneficial rumen and gut microorganisms supply nutrients to ...

I . The concentrations of volatile fatty acids (VFA) in the rumen and caecum were compared when sheep were given barley or dried grass. The molar proportions of VFA in the caecum resembled those in the rumen except that the proportions of isobutyric and isovaleric acids were higher in caecal than in rumen fluid indicating an extensive breakdown of protein during fermentation in the caecum. 2. T...

The objective of this study was to investigate the effect of microbial oil on rumen fermentation of a diet composed of 60% hay and 40% barley in an artificial rumen (Rusitec). Microbial oil (MO) was produced by the fungus Thamnidium elegans. This fungus grew on the wheat bran/spent malt grains (3:1) mixture. The fatty acid composition of microbial oil was as follows: 0.7% C14:0, 15.4% C16:0, 10...

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...
