# Exploring Aubrac Cattle as a Benchmark for Sustainable and Nutritious Beef Production

## TL;DR

Aubrac cattle produce tender, flavorful beef that is also highly nutritious and beneficial for heart health.

## Contribution

This study provides the first detailed nutritional analysis of Aubrac beef, highlighting its superior protein quality and heart-healthy fat profile.

## Key findings

- Aubrac beef contains all essential amino acids in amounts exceeding international dietary recommendations for all age groups.
- The meat has a favorable fat profile with high oleic acid content, which is beneficial for cardiovascular health.
- The protein quality of Aubrac beef is confirmed by high amino acid concentrations and biological value.

## Abstract

Beef quality is an important factor for both consumers and farmers, as it combines taste, tenderness, and nutritional value. The Aubrac cattle breed, originally from France and now increasingly raised in Eastern Europe, is known for producing flavorful meat, but little is known about its nutritional characteristics. In this study, we analyzed the meat of Aubrac cattle to better understand its protein and fat composition. We found that the meat provides all the essential amino acids required for healthy growth and development, in amounts that go beyond international recommendations for children, youth, and adults. In addition, the meat contains a favorable balance of fats, with a high level of oleic acid, which is considered beneficial for heart health. These results show that Aubrac beef is not only tender and tasty but also a valuable and healthy source of protein. This information can help consumers make informed dietary choices, encourage farmers to adopt sustainable production systems, and support the promotion of high-quality beef that contributes to human health and well-being.

The Aubrac cattle breed, native to France and increasingly adopted in Eastern Europe, is known for producing tender, flavorful, and well-marbled beef. Despite its growing popularity, limited data exist on its nutritional profile and implications for human health. This study evaluates carcass traits and protein quality in the Longissimus dorsi muscle of male and female Aubrac cattle raised under semi-intensive systems. Special attention was given to essential and semi-essential amino acids, which exceeded FAO/WHO reference requirements by 60.25%, 97.43%, and 221.49% for children, youth individuals, and adults, respectively, confirming superior protein quality. The high amino acid concentration (up to 30.59 g/100 g protein) and biological value confirm superior protein quality. Furthermore, the fatty acid profile reveals a favorable balance between saturated and unsaturated fats, with oleic acid predominance and a moderate atherogenic index, suggesting cardiovascular benefits. These findings support classifying Aubrac beef as a functional protein source with potential health advantages, reinforcing its role in sustainable cattle production, dietary planning, and consumer education. This study provides insights into factors influencing beef quality, connecting cattle breed and production system with nutritional value and health benefits.
