The demand for animal protein is rising, increasing pressure on animal production systems and ecological resources. Ethical and environmental concerns are also growing worldwide, pushing for more sustainable food production systems. The international scientific community has raised concerns about misinformation regarding meat production processes and their harmful impact on the environment, animal welfare and human health consumption.

Sixty Hereford (H) and Braford (B) steers were assigned to two different diets for finishing purposes: (D1) native pasture plus corn grain (1% of live weight) (H = 15, B = 15) and (D2) high-quality pasture (H = 15, B = 15). The average daily gain was registered every 14 days, and temperaments were individually assessed one week before slaughter by three individual tests: crush score, flight time and exit speed, building a multicriterial temperament index (TIndex).

- The experiment assessed how different fattening systems (varying from pasture-only to different combinations of pasture and concentrate feed) and animal temperament affected animal welfare and meat quality in Hereford steers.
- Eighty-four steers were divided into four groups based on their diet, and temperament was measured using various tests to create a temperament index.
- Results showed that while the highest concentrate diet led to the best growth rates, it negatively impacted animal welfare, but calmer animals across all diets generally showed better growth and meat quality.
