Which stressors impact your cows?

How do stressors interact to impact your revenue?

There are different types of stressors that lead to metabolic strain, all of which affect the health, well-being, and performance of our dairy cows.

What are the major stress factors?

Stress factors

Stage of production

  • Dry-off
  • Close-up
  • Calving
  • Fresh period
  • Early lactation
  • Weaning


  • Heat stress
  • Cold, Humidity, Light
  • Adverse weather events
  • Excessive rain, snow


  • Feed availabilty & quality
  • Feeding frequency
  • Water supply and quality
  • Ration quality
  • Feed changes


  • Stocking density
  • Group changes
  • Mixed parity groupings
  • Bunk space
  • Health status
  • Lameness
  • Housing type
  • Ventilation
  • Lighting
  • Human-Animal


  • Metabolic Disease:
    • Related to transition period
    • Clinical & Subclinical ketosis
    • Milk fever
    • Metritis
  • Rumen and Gut Health:
    • Acidosis and subclinical
    • Inflammation
    • Lameness
    • Mastitis

What does stress and metabolic strain mean for the cow?

Short longevity

Lowers reproductive performance

Immune dysfunction

Increases cull rates and mortality

Reduces milk and component yield

Decreases sustainable production

The solutions


• Implement heat abatement strategies


• Protect animals from cold stress

• Good air quality


• Access to high quality water


• Adapted light program


• Animal comfort


• Ensure adequate feed and resting space


• Set a strategy to prevent metabolic diseases


• Zero lameness program


• Ensure well trained employees on interaction with animals


• Minimize negative energy balance

• Prioritize Rumen Health

• Ensure best quality feeds

• Ensure the ration is followed

• Supply essential nutrients in a form that guarantees the right level is absorbed by the cow: 

– Protected B Vitamins, Vitamins A, D & E, protected Selenium

Stage of production

• Focus investment on:

– Dry-off
– Close up
– Calving
– Fresh peak
– Breeding
– Calf weaning

• Providing exercise before calving 


• Focus your resources on the key stress period

• Implement a close follow-up with your vet on the health incidences that could be a sign of high levels of stress

• Guarantee the best quality on your nutritional program, supplying the right amount of nutrients to be absorbed by the cow, as protected B vitamins, protected vitamins A, D3 and E and protected selenium

Jefo’s solution:

Protected B vitamins & Protected Selenium

B vitamins are essential for all ruminants. As a key part of many metabolic processes, they promote optimal health, milk yield, and sustainable production systems.

Intestinal absorption of Selenium sources

Selenium helps reduce oxidative stress and improves animal resistance to infections.

The Selenium is more available for the animal, directly in the intestine.

Since we aim to develop solutions for life, made easier, we offer our customers practical strategies that ensure better feed and zootechnical performance of the herds. As a result, we have the right solution: profitable and sustainable production.

Jefo Matrix Technology has a high rumen bypass efficacy with excellent intestinal digestion. This will provide to the animal the needed B vitamin and selenium level to improve the immune status and the metabolism of the animal.
