Free Range, Intensive Farming and Animal Welfare

This lesson compares free-range farming with intensive farming and examines animal welfare concerns, as required by the AQA GCSE Food Preparation and Nutrition specification (8585), section 3.6. You need to understand the different farming systems, their implications for animal welfare, cost, food quality and the environment.

Intensive Farming (Factory Farming)

Intensive farming (also called factory farming or industrial farming) aims to produce the maximum amount of food at the lowest cost. Animals are kept in controlled, indoor environments with limited space.

Characteristics of Intensive Farming

Feature	Detail
Housing	Animals kept indoors in enclosed sheds or buildings; limited or no outdoor access
Space	High stocking density — many animals per square metre
Feed	Controlled diet, often including growth promoters; may include GM feed
Lighting	Artificial lighting may be used to extend "daylight" hours and increase egg production or growth
Temperature	Controlled environment to optimise growth
Antibiotics	Routine preventative antibiotics often used to prevent disease spread in crowded conditions
Natural behaviours	Severely restricted — animals cannot roam, forage, nest or dust-bathe normally
Cost	Lower production costs — cheaper food for consumers
Yield	High — maximises output per animal and per unit of space

Examples of Intensive Farming

Animal	Intensive System
Chickens (broilers)	Housed in large sheds; up to 20,000 birds per shed; reach slaughter weight in as little as 5–6 weeks (compared to 12+ weeks for traditional breeds)
Chickens (layers)	Enriched colony cages (battery cages were banned in the EU in 2012); restricted movement but more space than old battery cages
Pigs	Indoor units with slatted floors; sows in farrowing crates; limited movement
Cattle (dairy)	Some dairy cows kept indoors year-round ("zero-grazing"); milked by machine 2–3 times daily

Free-Range Farming

Free-range farming provides animals with access to outdoor areas during the day and more space to move and exhibit natural behaviours.

Characteristics of Free-Range Farming

Feature	Detail
Housing	Indoor shelter for protection at night; outdoor access during the day
Space	Significantly more space per animal; lower stocking density
Outdoor access	Animals can go outdoors, roam, forage and explore
Natural behaviours	Animals can scratch, peck, dust-bathe (poultry), root and explore (pigs)
Feed	Standard feed plus natural foraging
Antibiotics	Less routine use (lower disease pressure due to more space)
Cost	Higher production costs — more expensive for consumers
Yield	Lower per unit of space
Growth rate	Slower growth — animals take longer to reach market weight

Legal Standards for "Free-Range"

Animal	Legal Minimum Requirements
Free-range chickens (meat)	Must have continuous daytime access to outdoor runs with vegetation; maximum 13 birds per square metre indoors
Free-range laying hens	Must have continuous daytime access to outdoor runs; maximum 9 hens per square metre indoors; maximum 2,500 hens per hectare outdoors
Free-range pigs	Not legally defined in the same way, but outdoor-reared/outdoor-bred labels indicate varying levels of outdoor access

Comparison Table

Factor	Intensive	Free-Range	Organic
Space	Minimal	Moderate	Most
Outdoor access	None or very limited	Yes — daytime	Yes — with specific standards
Natural behaviours	Severely restricted	Possible	Encouraged
Growth rate	Fast (growth promoters)	Moderate	Slowest
Antibiotics	Routine preventative use	Less routine	Only when ill
Animal welfare	Lowest	Good	Highest
Cost to consumer	Cheapest	More expensive	Most expensive
Environmental impact	Pollution (waste, ammonia); lower land use per unit	Better welfare; moderate land use	Best environmental practices; higher land use
Taste	Standard	Often considered better	Often considered best
