Early Lactation Maximize your Profitability A

Early Lactation

Maximize your Profitability

From optimal transition
management to peak
milk performance
Jefo’s precision
nutrition solutions

In North America, the negative effects of suboptimal transition result in the lost opportunity to capture your herd’s full milk & profit potential.

The synegistic effect between our transition and lactation blends will result in optimizing early lactation performance.

B Vitamins are essential for the overall metabolism of the dairy cow.

B Vitamins act as Metabolic Reactors* to produce energy and protein, resulting in less energy loss and fewer health disorders.

*Metabolic Activators are B vitamins which are involved in various
metabolism as enzymes cofactors (activators)

Jefo blend of protected B vitamins for Transition

  • Glucose synthesis in the liver
  • Works synergistically with
    Folic Acid
  • Methyl donor
  • Improves fertility
  • Works synergistically with B12
  • Methyl donor
  • Improves fertility
  • Protects cells from oxidative stress
  • Milk protein synthesis
  • Increases milk fat
  • Synergistically works with
    folic acid and B12
  • Methyl donor
  • Protects cells from oxidative stress
  • Increases the concentration and function of immune cell


Jefo blend of protected B vitamins for Lactation

  • Glucose synthesis in the liver
  • Methyl donor
  • Improves fertility
  • Cofactor for methyl groups
  • Essential coenzyme in
    carbohydrate, fat and protein
  • Involved with gluconeogenesis,
    propionate metabolism, fatty acid
    synthesis, and amino acid
  • Follicular development 
  • Protects cell from
    oxidative stress
  • Metabolism of carbohydrates 
  • Synthesis of proteins and prostaglandins
  • Oocyte and early embryonic
  • Follicular development
  • Protects cells from oxidative stress
  • Energy generation cycle
  • Synthesis of essential fatty acids and protein

Feeding protected B Vitamins during the transition period results in significantly higher milk production in early lactation, translating into higher lifetime component yield.

Greater performance yield with protected B vitamins

  • Act as enzyme cofactors involved in the energy and protein metabolism of the dairy cow
  • Involved in glucose synthesis in the liver
  • Enhanced immune readiness

Maximize milk production

  • Increase dry matter intake
  • Easier start in lactation
  • Reduce the risk of subclinical ketosis
  • Reduce udder infections

An increase up to
4 kg DMI /day
through early lactation

Improve reproduction

  • Minimize metabolic disease
  • Faster return to positive energy balance
  • Improved oocyte and follicular health
  • Greater reproductive performance

Our research shows a ROI of 8:1
