• Not impossible to provide good welfare in large-scale livestock systems but very difficult
• And perhaps impossible in large-scale dairies

Farrowing crates severely restrict freedom of movement of sows & prevent normal nest-building behaviour : EFSA, 2007

• Freedom farrowing pens – can deliver
“significantly reduced mortality rates & improved growth patterns”.
• “We have also developed bespoke slurry flushing systems which allow straw to be used with slatted floors, providing increased comfort to our pigs and giving them the opportunity to forage & nest”:

“An intact curly tail may well be the single most important animal-based welfare indicator for weaned, growing and finishing pigs ”:
Technical Report prepared for EFSA in 2011

• “Advanced levels of animal welfare bring countless benefits to both our pigs and our business by reducing the stress levels in our animals, which we believe enhances pig performance”
Martin Barker, Midland Pig Producers

• Large –scale systems make it difficult to treat animals as individual sentient beings
• In large-scale systems it is possible, with first-rate management, to prevent the worst of welfare problems, but difficult to provide positively good welfare
• Welfare is about more than preventing ill-health, pain, discomfort, fear, distress, hunger & thirst
• It’s also about the ability to express innate/natural behaviour, to experience a positive sense of well-being

Large industrial units present health risks
• Concentrating too many animals in one place increases disease risks
• UN Food and Agriculture Organisation: industrial livestock production plays an important part in the emergence & spread of diseases
• European Medicines Agency: in production systems with a high density of animals, the development & spread of infectious diseases is favoured
• Leads to greater antibiotic use & antibiotic resistance

Large-scale dairy: Problems arise not so much from size but from practices commonly associated with large-scale dairies
• Large-scale dairies usually use high yielding cows
• EFSA: “ Long term genetic selection for high milk yield is the major factor causing poor welfare, in particular health problems, in dairy cows.”
• Opposed to zero-grazing - cows should have access to pasture during the grass-growing season - grazing is a core aspect of dairy cow behaviour
• EFSA: if dairy cows are not kept on pasture for parts of the year, there is an increased risk of lameness, mastitis & a range of other health problems

Dairies: in one respect large scale is a problem
• Cows kept in large group would need large area of pasture – walking back to milking parlour may be impractical
• So zero-grazing is stimulated

• DairyCo study: milk yield is not the main driver of profit
• production costs are key determinant of profit & feed costs (main component of overall costs) are lower in grass-based systems
• report shows grass-based systems can be as, or more profitable, than intensive indoor systems
• Indeed, from point of view of feed efficiency, revenue per litre & net margin per litre best option is for cows to be in a well-managed pasture-based system.

US study on environmental impacts of dairy:
Agricultural research, May-June 2011
• Title: ‘Putting dairy cows out to pasture: an environmental plus’
• GHG emissions 8% lower & ammonia emissions 30% lower in year round grazing than in indoor systems
• Outdoor systems do not require as much feed for livestock
• Fields formerly used for feed crops were converted to perennial grasslands big increase in carbon sequestration levels & substantial fall in sediment erosion & phosphorus run-off

• AD plants linked to mega-dairies & large scale pig units are used to argue that industrial farming is environmentally sound
• Over time the economics of AD drive operators to use more or only crops (e.g. maize) as fuel, and away from using animal waste
• AD linked to large dairy or pig units leads to only small reductions in
GHG emissions from livestock
• And if maize is grown as fuel, the GHG emissions from land use changes (e.g. caused by displacement of food production) could result in a net increase in GHG emissions
