    Rumen-protected methionine: a boost for primiparous dairy cows performance

    Methionine is considered the most limiting essential amino acid for ruminants (Schwab & Broderick, 2017). This element has a pivotal role in their productive performance and nitrogen efficiency.
  • Organic acid and plant botanical supplementation in heat-stressed Holstein calves

    Our findings in Holstein calves are early evidence that dietary microencapsulated OA/PB feeding is a means to partially restore feed intake and average daily gain post-weaning when challenged by heat exposure.
  • Effects of heat stress and dietary organic acids and botanicals on hepatic one-carbon metabolism

    Heat stress develops with methyl donor deficiency in parallel with an impaired N metabolism. The supplementation of OA/PB improves the remethylation capacity in the liver. On-going transcriptomic analyses will provide a better understanding of the hepatic metabolism of dairy cows exposed to heat stress.
  • Effects of ambient heat exposure and dietary organic acids and pure botanicals on gut permeability and milk production

    Heat exposure compromises the gastrointestinal barrier and leads to inflammation in non-ruminants. Our results indicate that heat stress increases gut permeability and inflammation markers rapidly and independently of dietary intake.
  • Intestinal health: organic acids and pure botanicals can be extremely useful

    The impact that a molecule can have on animal metabolism and physiological functions is strictly linked to different modes of action of the molecule itself. These activities must be studied and well known to use the nutrition favoring both animal health and production effectively.
  • Effects of feeding 2 rumen-protected choline sources during the transition period on Holstein dairy cows performance and blood metabolites

    During the first weeks of lactation, dairy cows typically experience negative energy balance, leading to the mobilization of body reserves. This predisposes early lactating cows toward metabolic diseases, such as fatty liver syndrome and ketosis.
  • Thymol as an Adjuvant to Restore Antibiotic Efficacy and Reduce Antimicrobial Resistance and Virulence Gene Expression in Enterotoxigenic Escherichia coli Strains

    The aim of this study was to investigate the potential adjuvant effect of thymol to re-establish antibiotic efficacy against highly resistant ETEC field strains. Secondly, we evaluated the modulation of virulence and antibiotic resistance genes.
  • A mixture of organic acids and thymol protects primary chicken intestinal epithelial cells from Clostridium perfringens infection in vitro

    In this study, the protective effects of a blend of thymol and organic acids against the effects of Clostridium perfringens type A on chicken intestinal epithelial cells were investigated and compared to bacitracin, a widely used antibiotic in poultry production.
  • Dual Antimicrobial Effect of Medium-Chain Fatty Acids against an Italian Multidrug Resistant Brachyspira hyodysenteriae Strain

    In this study we tested four antibiotics (tylosin, lincomycin, doxycycline, and tiamulin) and medium-chain fatty acids (MCFA; hexanoic, octanoic, decanoic, and dodecanoic acid) against an Italian field strain of B. hyodysenteriae and the ATCC 27164 strain as reference.
  • Phenol-Rich Botanicals Modulate Oxidative Stress and Epithelial Integrity in Intestinal Epithelial Cells

    The aim of this study was to screen the activity of different sources of phenol compounds on intestinal oxidation and barrier integrity in vitro.
  • Phenol-Rich Botanicals Modulate Oxidative Stress and Epithelial Integrity in Intestinal Epithelial Cells

    The aim of this study was to screen the activity of different sources of phenol compounds on intestinal oxidation and barrier integrity in vitro.
  • Phenol-Rich Botanicals Modulate Oxidative Stress and Epithelial Integrity in Intestinal Epithelial Cells

    The aim of this study was to screen the activity of different sources of phenol compounds on intestinal oxidation and barrier integrity in vitro.
  • Phenol-Rich Botanicals Modulate Oxidative Stress and Epithelial Integrity in Intestinal Epithelial Cells

    The aim of this study was to screen the activity of different sources of phenol compounds on intestinal oxidation and barrier integrity in vitro.
  • Organic acids and botanicals supplementation on lactation performance in heat-stressed dairy cows

    Twenty multiparous non-pregnant Holstein cows were enrolled in a study with a completely randomized design. Cows were assigned to one of two groups fed a basal diet supplemented with 25g/d of AviPlus®R (TRT) or basal diet supplemented equivalent triglyceride used for microencapsulation (CTR).
  • Intestinal health helps preventing milk loss linked to ketosis and heat stress

    From an economic point of view, the lack of metabolic adaptation at the beginning of lactation (ketosis) and heat stress are two of the most important diseases for dairy cows as they seriously jeopardize the competitiveness of world animal husbandry and significantly reduce its efficiency.
