Summary

This crossover field trial examined the effects of incremental flaxseed supplementation (0–500 g/day) in the diet of lactating Holstein dairy cows on milk production and fatty acid composition. The study utilised a controlled design with nine cows across three treatment periods to isolate the influence of flaxseed inclusion. The findings likely contribute to understanding how oilseed supplementation modulates milk fatty acid profiles, with potential implications for nutritional quality and human health outcomes of dairy products.

UK applicability

Findings are potentially applicable to UK dairy systems, though regional differences in forage quality, housing systems, and breed genetics may influence absolute performance responses. The methodology and flaxseed inclusion rates are relevant to UK dairy farming practice, though local validatory studies would strengthen evidence for routine adoption.

Key measures

Milk yield, milk composition (fat, protein, lactose), milk fatty acid profile, production performance metrics

Outcomes reported

The study measured dairy cattle production performance (milk yield, composition) and milk fatty acid profiles across three dietary flaxseed inclusion levels (0, 250, and 500 g/day). Changes in milk fatty acid composition, particularly omega-3 and omega-6 polyunsaturated fatty acids, were likely evaluated as primary outcomes.
