  • 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.
  • 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.
  • Assessing intestinal health. In vitro and ex vivo gut barrier models of farm animals: benefits and limitations

    The concept of “gut health" is not well defined, but this concept has begun to play a very important role in the field of animal science. However, a clear definition of GIT health and the means by which to measure it are lacking. In vitro and ex vivo models can facilitate these studies, creating well-controlled and repeatable conditions to understand how to improve animal gut health.
  • Heat stress develops with increased total-tract gut permeability, and dietary organic acid and pure botanical supplementation partly restores lactation performance in Holstein dairy cows

    The aim of this study was to evaluate the effects of heat stress (HS) conditions and dietary organic acid and pure botanical (OA/PB) supplementation on gut permeability and milk production.
  • Effects of two rumen-protected choline sources during transition period on Holstein dairy cows performance

    The objective of this study was to evaluate the effect of two sources of rumen-protected choline (RPC) supplemented from 21 d pre- to 35 d postpartum.
  • Evaluation of a rumen-protected methionine product for lactating dairy cows at 2 concentrations of dietary crude protein

    This study evaluated the effect of a supplemental rumen-protected Met product (Timet; VETAGRO S.p.A.; Reggio Emilia, Italy) on lactation performance and rumen measures of dairy cows fed 2 concentrations of dietary CP.
  • In situ rumen degradability and in vitro intestinal digestibility of rumen-protected methyl donors and lysine

    Rumen degradation and intestinal digestibility of rumen-protected (RP) methyl donor and lysine products vary. Our objectives were to evaluate the in situ rumen degradability and in vitro intestinal digestibility of 4 RP products containing choline chloride, dl-methionine, betaine, and/or l-lysine in a triglyceride matrix.
  • Effects of supplementing rumen protected methionine on performance of primiparous dairy cows during Presynch-Ovsynch protocol

    The objectives of this study were to evaluate the effects of supplementing three levels of rumen-protected methionine (RPM) at two levels of protein (14 vs. 16% CP) on reproductive and productive performance in primiparous lactating dairy cows during timed artificial insemination (TAI) protocol.
  • Effect of supplemental rumen-protected methionine on reproduction and production of Awassi ewes

    Feeding a rumen-protected methionine (RPM) supplement improved milk production in lactating dairy cows, lactating goats, or ewes. In this study, we hypothesize that feeding RPM would enhance reproduction and production in Awassi ewes.
  • How to improve colostrum quality

    Ruminants placenta avoids immunoglobulins transfer from the mother to the fetus (passive immunity). Calves are not protected against infections until they develop their own active immunity, except for antibodies received through colostrum.
  • Effects of microencapsulated methionine on milk production and manure nitrogen excretions of lactating dairy cows

    The study objective was to determine the effects of rumen-protected methionine (Met) by microencapsulation (RPM) on amino acid (AA) supply to the udder, milk production, and manure nitrogen (N) losses of dairy cows.
  • An effective replacement herd is based on the optimal colostrum management

    In general, 25-30% f the herd must be replaced every year. A restocking plan aims to rear healthy heifers to replace, two years later, the culled cows, with improved production and genetic value of the herd. High-quality heifers at the best cost possible are essential to put in place this plan and maximize income.
  • Characterization of the plasma lipidome in dairy cattle transitioning from gestation to lactation: identifying novel biomarkers of metabolic impairmentCharacterization of the plasma lipidome in dairy cattle transitioning from gestation to lactation: identifying novel biomarkers of metabolic impairment

    The discovery of novel biomarkers for peripartal diseases in dairy cows can improve our understanding of normal and dysfunctional metabolism, and lead to nutritional interventions that improve health and milk production.
  • Microencapsulated sodium selenite supplementation in dairy cows: effects on selenium status

    The objective of this study was to compare the efficiency of transfer of selenium (Se) to plasma and milk from inorganic sodium selenite, either free or microencapsulated, and from selenized yeast in dairy cows.
