• 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.

• Improved livestock sustainability through dietary protein correct management

  Global market means that every fluctuation in the raw material price has an impact on the worldwide economy and our farms. In addition to raw material price decrease, farmers often face fluctuation in milk selling prices. Economic efficiency is kept under continuous review: some fields of the livestock sector are already used to manage tight margins of profit, while dairy cows rearing has a hard time identifying its weak points.

• Blood methionine and lysine concentration in lactation dairy cows supplemented with commercial rumen-protected methionine and lysine products

  It is well known that methionine (Met) and lysine (Lys) are two of the most limiting amino acids (AA) for milk and protein production in lactating dairy cows fed corn-based diets (Schwab et al., 2003; Rulquin, 2004).
