Efficacy of Dietary Urea-Impregnated Zeolite in Improving Rumen Fermentation Characteristics of Local Lamb [PDF]

, 2012
A research on dietary inclusion of urea-impregnated zeolite as slow-release urea (SRU) agent had been conducted to reveal its effect on ruminal fermentation characteristics in local lambs. The research used 24 heads of 7-8 mo old of local male lambs with

Quantitative analysis of ruminal methanogenic microbial populations in beef cattle divergent in phenotypic residual feed intake (RFI) offered contrasting diets [PDF]

, 2014
peer-reviewedBackground Methane (CH4) emissions in cattle are an undesirable end product of rumen methanogenic fermentative activity as they are associated not only with negative environmental impacts but also with reduced host feed ...

The Efficacy of Food‐Grade Substances to Protect Dietary Glutamine From Ruminal Degradation

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study was conducted to investigate the use of four, low cost, food‐grade substances to protect glutamine from microbial degradation in vitro, and subsequently validate their efficacy in vivo. Two in vitro trials were conducted using 250 mL bottles replicated in triplicate to test beeswax‐, paraffin wax‐, zein‐, and rice bran wax ...

Effect of live yeast on ruminal biohydrogenation. A preliminary in vitro approach [PDF]

, 2009
Introduction : Ruminant dietary feed additives such as live yeasts are used on field because of their ability to induce a better diet utilisation. Even if studies on their mode of action are still going on, references are scarce about live yeast diet ...

Forage Biomass and Chemical Composition of Buffelgrass Genotypes in the Semi‐Arid Region of Brazil

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Forage improvement in semi‐arid regions requires the identification of genotypes capable of maintaining productivity under climatic variability and chronic water scarcity. This study evaluated six buffelgrass (Cenchrus ciliaris L.) genotypes over two production years in northern Minas Gerais, Brazil, to characterize their agronomic, morphological, and ...

The effect of individuality of animal on diurnal pattern of pH and redox potential in the rumen of dry cows

Czech Journal of Animal Science, 2010
The aim of this study was to continuously monitor ruminal pH and redox potential of individual dry cows using a newly developed wireless device. Three dry Holstein cows fitted with rumen cannulas were used for the individual measurement of ruminal pH and

A Mathematical Approach to Predicting Biological Values from Ruminal pH Measurements [PDF]

Journal of Dairy Science, 2007
The use of continuous recording to monitor ruminal pH has received growing attention. Continuous ruminal pH data are usually summarized for each 24-h period for each cow by calculating mean pH, maximum pH, minimum pH, amount of time (min/d) below pH 5.6 and 6.0, and area (time x pH) below pH 5.6 and 6.0.

Quality of Forage Cactus Silage with the Addition of Hay from Forages Adapted to the Semiarid Region

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
This study investigated the effects of including hays from different forages adapted to the semiarid region on the forage cactus (Opuntia fícus‐indica (L.) Mill) silage quality. A completely randomized design, with five treatments was used: pure forage cactus and forage cactus associated with 30% hay from gliricidia (Gliricidia sepium), pornunça ...

Investigation of Effects of Low Ruminal pH Values on Serum Concentrations of Macrominerals, Trace Elements, and Vitamins and Oxidative Status of Dairy Cows

Ruminants
Due to the feeding system (high-concentrate diet) during the early lactation stage, ruminal pH in dairy cows follows a diurnal pattern and can remain below the critical level of 5.5 for extended periods of the day. This study aimed to evaluate the effect

Effect of a glyphosate-containing herbicide on Escherichia coli and Salmonella Ser. Typhimurium in an in vitro rumen simulation system [PDF]

, 2019
Glyphosate (N-(phosphonomethyl)glycine) is the most-used herbicide worldwide. Many studies in the past have shown that residues of the herbicide can be found in many cultivated plants, including those used as livestock feed.
