Noninvasive biomarkers of rumen function are required to develop precision nutrition with no constraints on animal welfare. Alterations in caused by diets high acidogenic potential may be used as a model where fermentation affects the profile volatile organic compounds (VOC) fluid headspace and other matrices host ruminant, such breath, urine, feces, milk, or sweat. We selected-ion flow-tube mass spectrometry (SIFT-MS) test volatolome fluid, sweat, milk discriminate contrasting lactating...
A phytochemical investigation of Diplotaxis virgata D.C. and D. erucoides (L.) (Brassicaceae) offered to the isolation two new flavonoids isorhamnetin-3-O-α-l-glucopyranoside (1) rhamnetin-3,3ʹ-di-O-β-d-glucopyranoside (2), respectively. Their structures have been elucidated from extended spectroscopic methods, including 1D- 2D-NMR, UV mass spectrometry analysis by comparison with literature data. The fatty acid composition hexane extracts species was also investigated using GC-MS....
Today, one of the major challenges dairy farmers is to reduce their environmental footprint establish more effective, efficient, and sustainable production systems. Feed additives such as yeast probiotics could potentially allow them achieve these objectives through improvement milk production, feed efficiency, ration valorization, hence mitigating impacts production. In this study, life cycle assessment (LCA) principle was performed estimate impact supplementation a commercial probiotic...
The aim of this study was to use a meta-analytic approach evaluate the effect commercially available yeast probiotic “Actisaf® Sc 47” (Saccharomyces cerevisiae CNCM I-4407) produced and marketed by Phileo Lesaffre on milk performance in dairy cows. Data from 22 trials including 17 with parallel designs 5 cross-over were collected, only data analyzed. From those trials, 4 are published 13 technical reports. In total, 34 comparisons 1074 cows met criteria for inclusion final analysis...
The objective of this study was to evaluate the use a faeces sieving tool “Digescan” as an indicator feed valorization, and test influence feeding strategy on fecal particle size (PS) distribution weight, milk performance possible association between them. Data from 95 trials were used. During each trial, two periods identified: before during live yeast probiotic (LYP) supplementation. LYP used at 5 g/d/cow Saccharomyces cerevisiae (CNCM I-4407, 1010 CFU/g, Actisaf® Sc47; Phileo by Lesaffre,...
Abstract The study evaluated the dose effect of dietary supplementation with yeast probiotic Saccharomyces cerevisiae (CNCM I-4407, 1010 CFU/g, Actisaf Sc 47; Phileo by Lesaffre, France) on production, energy metabolism, and reproduction in lactating dairy cows. About 117 multiparous Holstein cows from 3 to 60 d milk held a barn an automatic milking system were enrolled randomized complete block design blocked according calving day, parity, previous yield. assigned basal diet (15% CP, 22%...
The goal of calf feeding systems is to provide calves with optimum nutrition promote growth, health, and future milk production reduce antibiotic use which leads a need for alternatives that illness growth in dairy calves. We hypothesized live yeast would improve gastrointestinal health performance aim this study was then evaluate the effects supplementing probiotic
The administration of yeast products as feed additives has been proven to beneficially affect animal productivity through energy, oxidative, and immune status improvement. This study evaluated a combination Saccharomyces cerevisiae live (LY) with postbiotics (rich in mannan-oligosaccharides (MOS) beta-glucans) selenium (Se)-enriched on ewes' milk performance quality, energy oxidative status, gene expression related their system during the peripartum period. Ewes were fed basal diet (BD; F:C...
Increasing animal protein, especially from beef, is necessary to satisfy the requirements of growing global population. However, this becoming increasingly challenging due stakeholders prioritizing sustainable systems with low environmental impacts. To answer these challenges, use feed additives such as yeast probiotics seems be an effective route for improvements in efficiency and growth performance. The current study was performed quantify impacts production a probiotic (Actisaf
