A study conducted by Dairy Australia, the national service body for the Australian dairy industry compared the different crossbreds and purebred herds on a pasture-based system. The researchers analysed data from more than 23 million lactation records from almost 900,000 cows on 18,207 farms.
The study showed that in terms of the three-way cross, there is no significant difference in volume of milk; however, the protein and fat percentages, the survival (how long the cows are in the herd), conception rate (CR), the six weeks In Calf Rate (6wICR) of the three breed cows outperformed the backcross animals (two cross system).
How can it be possible to have higher gross margins on the same amount of milk?
- the long-term commitment brings the best results,
- the smaller size of the cows brings benefits
- the importance to select only the best bulls of every breed
