Setting a specific genomic breeding strategies to improve the performance of the low performers cow in the herd and to reduce rearing costs.

Why does it matter?

Milk production is a partially inherited trait. Poor matching between cows and sires results in less healthy and less productive cows, increasing costs overtime. By contrast, implementing tailored genomic breeding strategies can improve the performance of cows and can reduce rearing costs.

How did we solve this?

We carried out genetic testing on 58 characteristics and traits of the herd (e.g. milk and fat protein etc.), which enabled the creation and implementation of a specific breeding strategy, without having to wait multiple generations. The breeding strategy is reported in a Dairy Dashboard to determine animals’ path based on the ranking in which the best female performers are inseminated based on genetic criteria.

On the farm the baseline has been assessed via a genetic test. By implementing breeding strategies, cow longevity is expected to increase by 79,5 productive days. The solids are also expected to increase from 1,44 to 1,71 (kg/ cow/ day). Additionally, breeding strategies based on genomic testing help optimise rearing replacements that meet minimum standards and reduce costs.

Opportunities for other farms?

Efficient genomic breeding strategies can be implemented on all farms. It helps to valorise the animal value by having more insights on breeding decisions and inherited genetic diseases.
