Total numbers of protozoa can be significantly lower in rumen fluid than in whole rumen contents, depending on the time of sampling and the procedure used to separate the fluid and solid fractions. Moreover, generic distribution in rumen fluid was significantly affected in all cases tested. The percentage of Entodinium spp. increased, whereas percentages of Diplodinium spp. and Ophryoscolex spp...

During the past few years several investigators have reported the isolation of lactobacilli or lactobacilli-like organisms from the rumen liquor of cattle and sheep. Gall and Huhtanen (1951) isolated several gram positive, nonsporeforming rods from rumen fluid which produced lactic acid from glucose, but they were not further identified. Some lactobacilli found by Rodwell (1953) in a sheep's ru...

Ruman degradation is crucial in the supply of dietary nutrients to meet the nutrient demands of the anaerobic microbes and body tissues of ruminant animals. Therefore, it is essential to study the dynamics of rumen degradation of various feeds before their potential use to formulate nutritious diets for ruminant animals. Amongst many methods that have been used in the past, the in sacco method ...

Forty two small ruminants, 26 (61.90%) sheep and 16 (38.10%) goats were treated for rumen acidosis. 19 (45.24%), 12 (28.57%), 6 (14.29%) and 5 (11.90%) animals had eaten apple, cooked rice (wazwan left over) turnip and chapatti respectively and manifested clinical form of ruminal acidosis with, 2.86%; (n=18) as mild (Rumen fluid pH=6.32 ±0.09316), 38.09%;(n=16)moderate (Rumen fluid pH=5.71 ±0.0...

The effect of rumen microbes on six mycotoxins (aflatoxin B1, ochratoxin A, zearalenone, T-2 toxin, diacetoxyscirpenol, and deoxynivalenol ) considered to be health risks for domestic animals was investigated. The mycotoxins were incubated with intact rumen fluid or fractions of rumen protozoa and bacteria from sheep and cattle in the presence or absence of milled feed. Rumen fluid had no effec...

the major aim of this study was to compare the morphology and activity of rumen protozoa of khuzestan water buffalo and holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. to separate rumen protozoa, antibiotic solution and fungicides were added...

Cattle manure is frequently used as an inoculum for the start-up of agricultural biogas plants or as a co-substrate in the anaerobic digestion of lignocellulosic feedstock. Ruminal microbiota are considered to be effective plant fiber degraders, but the microbes contained in manure do not necessarily reflect the rumen microbiome. The aim of this study was to compare the microbial community comp...

Hydrogen is a central metabolite in rumen fermentation and its partial pressure is an important determinant of rumen methanogenesis. The balance of hydrogen ion (H+) and dissolved hydrogen gas (H2) concentrations directly determine the redox potential of the rumen and therefore the possible extent of oxidation of feedstuffs. Differential permeability of the bacterial membrane to H+ and H2 means...

The digestion and utilization of roughage by sheep depends on rumen digestion. The aim of this study was to evaluate the microbe quantity and fermentative efficiency of rumen supplement with molasses-urea. This experiment was conducted in 2014, eight sheep were selected and divided into two groups (a control group and a treatment group), and only the treatment group animals were supplied with m...
