Intensive beef feedlot systems confine cattle at high densities on cereal-based diets for rapid weight gain, with welfare concerns including restricted movement, behavioural frustration and metabolic disease.
Cattle in feedlots cannot graze or perform natural foraging behaviour. High-concentrate diets cause subacute rumen acidosis in a proportion of animals, causing chronic discomfort and liver abscesses. Pen floors with inadequate bedding cause leg and foot problems. Social grouping of unfamiliar cattle causes initial aggression that may result in injuries. The welfare profile of feedlot beef production is substantially inferior to extensive grazing systems.
