Herd Improvement Overview

Over time the efficiency of NZ dairy cows has steadily improved.
1. Reproduction

Good repro gives you choice - but is the result of a year-round approach.
2. The cows you keep

Not all cows are created equal.
3. The calves you rear

Increase the rate of genetic gain by retaining your highest BW heifer calves to rear as replacements.
4. The bulls you use

The most gains in BW are generated from sire decisions.
