Evaluating the effect of fermented rapeseed meal on milk production and metabolic processes in dairy cows
Why protein matters
High milk production starts with well-managed feeding. Even where feed quality is good, diets may lack high-quality protein. Protein supports growth, development and milk production, but quality matters as much as quantity. Bypass protein is especially valuable for cows: it passes through the rumen without being broken down and is absorbed in the intestine. Conventional sources, such as oilseed meals and cakes, mainly contain readily degradable protein and do not fully meet cows' amino acid requirements. This places pressure on rumen function and reduces nutrient-use efficiency.
Canolac as a source of fermented protein
Modern farms increasingly use alternative protein sources, including fermented rapeseed meal. Its advantage is a higher content of rumen-undegradable protein and essential amino acids.
Canolac is one example. Based on fermented rapeseed meal, it provides an effective source of feed protein.
Canolac helps:
It makes conventional diets more nutritious and effective by supplying high-quality protein for cows.

Canolac helps:
- Increase the proportion of fermented protein in the diet;
- Improve amino acid utilisation;
- Balance protein nutrition in cows;
- Reduce pressure on the rumen microbiome.

Practical results
A trial in lactating cows evaluated Canolac by replacing part of the conventional rapeseed meal with fermented meal. The best result was obtained when 50% of the conventional meal was replaced with Canolac. This proportion produced the greatest improvement in milk production and metabolic function:
Blood analysis also showed a reduction in total protein within the normal range. This indicated more efficient use of dietary protein for milk synthesis.
- Daily milk yield increased by 3.2%.
- Milk fat yield increased by 3.91%.
- Milk protein yield increased by 3.21%.
Blood analysis also showed a reduction in total protein within the normal range. This indicated more efficient use of dietary protein for milk synthesis.
Conclusion
Including fermented rapeseed meal in lactating-cow diets supports more efficient and productive feeding. Canolac improves dietary protein nutrition, supplies fermented protein and helps increase milk production.
Its use demonstrates how innovative feeding solutions can deliver tangible economic benefits for farms.
