Within Herd Management, the Genetics tab provides a breakdown of Breeding Worth (BW), Production Worth (PW), breed and age for your herd. There are 6 interactive graphs that you can view including:

  1. Breeding Worth By Age

  2. Breeding Worth By Year Born

  3. Breeding Worth vs Production Worth

  4. Breeding Worth National Comparison

  5. Production Worth vs Holstein Friesian Breed 16th

  6. Herd Age Structure


Breeding Worth By Age

Focusing on age, this graph shows the number of animals in your herd (within a particular BW range) broken down in the following age groups:

  • 1 year olds

  • 2 year olds

  • 3+ year olds

  • Whole herd.

By clicking on the age groups, you can include or remove different age groups on the graph to the right.


Breeding Worth By Year Born

Looking back at past years, see how your BW has progressed and see how your herd compares to the national averages and the top 5%.


Breeding Worth vs Production Worth

Compare your herds BW & PW and see how this has changed over the past years. Ideally, BW & PW should be as close as possible but a higher PW is also ideal. Why? This shows how the BW of an animal has been a good indicator of their production ability.


Breeding Worth National Comparison

Looking at every herd in New Zealand, see where your herd ranks compared to the top 5 and 10%.


Production Worth vs Holstein Friesian Breed 16th

Looking at PW and breed 16th, you can review the genetic variation of your herd. The centre of the circles looks at breed 16th and average PW for this groups of animals. The larger the circle, the greater the number of animals for the breed 16th.

If you have animals showing a breed 16th of 0, it just means there are no Holstein Friesian genetics in the group. If you'd like to see animals in different Groups, change the Showing animals from within.


Herd Age Structure

Looking at your herd, view the age structure compared to Dairy NZ's optimal. You can then use this information to optimise the potential of your herd when it comes to culling animals.
