Longlivity: Maximum or Optimum?  

A cows longevity is a crucial aspect to operating income. A cow needs 1.5 lactations to cover the purchase and rearing costs. So, getting many lactations is important.

Actually, the age of a cow is not our concern, it’s the amount of milk (kg) and preferably the amount fat and protein it has delivered during her productive life. (LDY: Lifetime Daily Yield)

A couple of things are important to know:

  1. Heifers that calve at 23-24 months produce 15000 litres more in their lifetime than heifers that calve at 27-30 months;
  2. Using consequently DelPro’s 2-Minute-Check, information concerning cows with abnormalities are detected earlier: timely intervention makes a difference in longevity;
  3. Giving a cow after calving the right amount of a certain feed assists her trough the transition period and also helps thereafter going through the period with negative energy balance. Additionally, making sure these two periods the appropriate amount and speed is crucial in these periods;
  4. Precisely estimating if a treatment has a big chance or a little chance of succes for the cow.
  5. Or can/will she transmit infectious diseases? That could make a difference in the longevity of the cows stable mates;
  6. Etc. Etc.

 

But:

If a cow has calved ca. 4 times already, then ask yourself: must I have her inseminated again?
Or is there a bigger chance that the next lactation is better for the vet, hooftrimmer and cattle dealer than it is for my wallet?
