Effects of hop varieties on ruminal fermentation and bacterial community in an artificial rumen (rusitec)

Journal of the Science of Food and Agriculture, 2012
AbstractBACKGROUND: There is a growing interest in the use of hops (Humulus lupulus) as an alternative to antibiotics to manipulate ruminal fermentation. However, the effects of different hop varieties on ruminal fermentation and bacterial populations have not been studied.

Effect of methanol on methanogenesis and fermentation in the rumen simulation technique (RUSITEC)

Journal of Animal Physiology and Animal Nutrition, 1999
Introduction  Major methanol sources in ruminant feeds are pectins esterified with methoxyl groups. Methanol can be released by pectin esterase activity of rumen bacteria (R exova‐B enkova and M arkovic 1976). It has been detected in rumen fluid of cows in vivo and in vitro (V antcheva et al. 1970, 1972).

Impact of lysozyme on ruminal fermentation and microbial population in Rusitec fermenters

Ankara Üniversitesi Veteriner Fakültesi Dergisi
The aim of the present study was to investigate the in vitro effects of two lysozyme doses (10 and 50 FIP U/mL) on rumen fermentation and microbial populations using the artificial rumen system Rusitec with an 80:20 concentrate-to-forage diet.

Effects of 3-nitrooxypropanol on methane production using the rumen simulation technique (Rusitec)

Animal Feed Science and Technology, 2015
Abstract The purpose of this study was to evaluate the effect of different doses of 3-nitrooxypropanol (NOP) to a backgrounding diet on methane (CH4) emissions using the in vitro rumen simulation technique (Rusitec). 3-Nitrooxypropanol is an enzymatic inhibitor that has consistently reduced CH4 emissions in sheep, dairy and beef cattle (up to 59 ...

Use of the rumen simulation technique (RUSITEC) to compare microbial digestion of various by-products

Animal Feed Science and Technology, 1988
Abstract A semi-continuous culture system, adapted from the rumen simulation technique (RUSITEC) was used to compare the rumen micro-organism fermentation of different by-products. The following by-products were studied: (1) concentrates: citrus pulp; beet pulp; corn gluten feed; wheat bran; (2) roughages: untreated straw samples; straw samples ...

Effect of elevated cobalt intake on fermentative parameters and protozoan population in RUSITEC

Animal Feed Science and Technology, 2001
Abstract The effects of 2, 4 and 8 mg cobalt per kg dry matter (DM) of feed ration consisting of 11.5 g hay, 2.8 g barley and 1.6 g molasses (10% of the DM feeding ration) were examined in an artificial rumen simulation technique (RUSITEC) as affecting fermentation and protozoan population.

Effects of gallic acid on in vitro rumen fermentation and methane production using rumen simulation (Rusitec) and batch-culture techniques

Animal Production Science, 2019
Two experiments were conducted to investigate the effects of adding gallic acid (GA) to ruminant diets on long- and short-term in vitro rumen fermentation and methane (CH4) production, and to test possible interactions between GA and ethanol on ...
