Copaiba oleoresin as a substitute for sodium lasalocid in high‐concentrate diets for lambs: growth performance, ingestive behavior, and metabolic and ruminal parameters

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The indiscriminate and excessive use of ionophore additives has been associated with the emergence of multi‐resistant pathogenic strains and the global spread of antibiotic resistance, raising serious public health concerns. Thus, plant biocompounds have been the focus of several studies aiming to replace ionophore additives in ...

Effects of heating process of soybeans on ruminal production of conjugated linoleic acids and trans-octadecenoic acids in situ [PDF]

, 2006
The effects of two thermal treatments of soybeans, i.e. roasting (150˚C dry heat) and extrusion (140-150˚C), on conjugated linoleic acids (CLA) and trans-octadecenoic acids (trans-C18:1) productions obtained throughout ruminal C18:2 biohydrogenation in ...

Pathophysiological evaluation of subacute ruminal acidosis (SARA) by continuous ruminal pH monitoring

Animal Science Journal, 2015
AbstractEvaluation of the radio‐transmission pH‐measurement system for monitoring the ruminal pH and subacute ruminal acidosis (SARA) in cattle is described. This is done in order to reveal the possible application of this system for detection and pathophysiological research of SARA by continuous ruminal pH measurement.

Investigation of the Effect of pH on the Adsorption–Desorption of Doxycycline in Feed for Small Ruminants

Antibiotics, 2023
Orally administered tetracycline antibiotics interact with feed, which may impact their bioavailability and efficacy. Therefore, the pH-dependent adsorption of doxycycline and its interaction with feed for ruminants was studied in vitro. Adsorption experiments on animal feed (135 and 270 mg) with initial doxycycline concentrations of 35, 75, and 150 µg/

Styrene and its natural analogues: accumulation and sustainable production methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...

Carryover of Aflatoxin From Dairy Feed to Milk: A Systematic Review (1 January 2004–31 December 2024)

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Aflatoxins, toxic metabolites produced by Aspergillus species, are frequently reported contaminants of dairy cattle feed worldwide, particularly in tropical and subtropical regions where climatic conditions favor fungal growth, and they can be transferred into milk and dairy products.

Evaluation of models to predict the stoichiometry of volatile fatty acid profiles in rumen fluid of lactating Holstein cows [PDF]

, 2011
Volatile fatty acids (VFA), produced in the rumen by microbial fermentation, are the main energy source for ruminants. The VFA profile, particularly the nonglucogenic (acetate, Ac; butyrate, Bu) to glucogenic (propionate, Pr) VFA ratio (NGR), is ...

Ability of pH-Selected Mixed Ruminal Microbial Populations to Digest Fiber at Various pHs [PDF]

Applied and Environmental Microbiology, 1986
Inocula from pH 5.5-selected rumen microorganisms failed to digest fiber any better in batch culture at pH 5.0 or 5.5 than did inocula from pH 6.5-selected organisms. Furthermore, upon extended batch incubation, both the viable cellulolytic and amylolytic bacteria became increasingly associated with the fiber portion and less with the liquid portion of
