Nutritional value of suckler beef from temperate pasture systems

Summary

This whole-system study from the North Wyke Farm Platform compared the nutritional value of suckler beef from three temperate pasture systems—permanent pasture, grass and white clover, and short-term monoculture grass ley—over three production cycles (2015–2017). The authors found that despite subtle differences in fatty acid profiles between systems, the overall nutritional quality of beef remained largely consistent across all sward types, suggesting that temperate pasture-based beef can be treated as a single commodity for sustainability assessments. The findings support the argument that pasture-based beef represents a nutritionally dense food with potential to contribute meaningfully to human dietary adequacy when assessed on a nutrient-per-unit basis rather than mass.

UK applicability

These findings are directly applicable to United Kingdom beef production, being conducted within UK temperate conditions at a long-term research platform. The results support the classification of UK pasture-based beef as nutritionally consistent regardless of specific pasture type, which has implications for producer marketing and sustainability claims in UK food systems.

Key measures

Fatty acids, minerals, vitamin E content in beef and forage; omega-6 polyunsaturated fatty acid (PUFA) concentrations; recommended daily intake (RDI) percentages per 100 g serving

Outcomes reported

The study analysed the fatty acid, mineral and vitamin E profiles of beef produced from three common temperate pasture systems over three production cycles. Nutritional quality of beef was found to be largely comparable across all systems, with only subtle differences in omega-6 PUFA concentrations between grass–white clover and permanent pasture systems.
