• Assessment of issues for future development
• Today = Welfare –– No Mutilations – No Confinement
• Tomorrow = Environment – Social Responsibility – Carbon / Nitrate Efficiency
• Future = Human Health – Hygiene & fresh air = reduced antibiotics
• Outdoor production considered not able to achieve two out of three above.
0.8Ha Crop (6 tonnes)
=
1 sow
=
Fertiliser for 0.8Ha
• Crop rotation important to balance feed requirement with fertiliser output

• Commodity prices go down, interest rates go up.
• Our aim is have both a utility business and commodity business.
• Don’t write cheques, bank them.
• Three of the biggest costs in a farming business
• Feed, Fertiliser, Fuel,
Can all be produced on farm
• We aim to run all our tractors / harvesters on biogas
• Fertiliser companies charge us £300 tonne for Ammonia mixed with
Sulphuric acid (26% N liquid) – we do that ourselves for a fraction of
the cost
• In our business we grow over 90% of what we consume and consume
100% of what we grow

Separation system
Tanking water round the countryside is
not necessary – Solids to the (much
smaller) biogas plant – Liquids to the
ammonia stripping plant (sulphuric acid)
= low volume ammonium sulphate
fertiliser . Water can be evaporated off
using heat from biogas

High Welfare
Measuring stress can be done by recording tail
biting incidence. Ability to leave tails on pigs is
multi faceted problem. Temperature control,
environmental enrichment, stocking density,
genetics. But potentially £50 per pig difference
in cost if you reduce stress completely, the
holy grail of animal welfare groups.
