  1. Intensive farming Minimising energy loss

  2. Intensive farms are profitable • Maximise output by various methods Specially bred animals for high growth rates High digestibility diets that can include growth hormones and antibiotics if needed

  3. Methodology Wanted : Maximum output for minimum input High growth – low input Energy costs money- so waste as little as possible whether from the animal itself or the environment in which it is kept

  4. Poultry – battery hens • Restricted movement • High production diet • Controlled environment

  5. Pig battery • Restricted movement • High digestibility diet • Hormones for growth added • Controlled environment

  6. Pig farms - indoor • Many pigs occupy small space – pigs per square metre • Keep each other warm • Is it ethical?????? • Animal welfare????

  7. Animal welfare • What’s more important to you – the consumer • Quality of your food? • Cost of your food? • How the animals you eat are treated? • Do you care? • IGNORANCE IS BLISS

  8. Welfare Ability to perform natural acts e.g. • Spreading wings and flapping – chicken • Scratching or grubbing in soil – pigs/chickens • Preening or rolling in dirt etc etc

  9. Selective breeding • Animals bred for food are bred for slaughter • More growth = more meat = more £

  10. ethics Problems : Chickens - growth so fast that leg bones break because they can’t support the weight of muscle put on Cow unable to give birth to calf that is too big so kill the cow (and sell carcass) save the calf – worth some money

  11. Management Problems • Enclosed animals – disease spreads quickly Use lots of antibiotics –don’t tell consumer Hormone enhanced meat – growth hormones can affect the consumer e.g. floppy man breasts

  12. IGNORANCE IS BLISS What you don’t know can’t hurt you TRUE Who or what does it affect??
