Areas of Expertise:

  • determining the vitamin B requirements, primarily folic acid and vitamin B12, of dairy cows and veal calves to optimize metabolic efficacy
  • study of the interactions between vitamin B and protein and energy metabolism
  • study of the absorption efficiency of vitamin supplements and the effects of these supplements on nutrient availability in dairy cows
  • study of B vitamin nutritional requirements for maximizing the synthesis and/or reducing the use of these vitamins by the rumen microflora
  • study of the impact of nutrition on nutritional quality, particularly concentrations of vitamin B12 in the meat and milk of ruminants
  • dairy cattle
  • animal nutrition, metabolism, absorption
  • nutritional requirements - methods for determining requirements

Current Projects:

  • Effects of folic acid vitamin B12 supplements during the prepartum period and early lactation on dairy herd productivity
  • Folic acid and vitamin B12, a winning team to increase efficiency of energy and protein metabolism of dairy cows: sites et modes of action
  • Vitamins B, key elements of metabolic efficiency: effects of nutritional strategies on supply
