- Intensive Rearing of Livestock
- This involves controlling the conditions that livestock live in, so more energy is used growth and less is used on other activities.
- The efficiency of energy conversion is increased so more biomass is produced and productivity is increased
- Animals may be kept in warm, indoor pens where their movement is restricted.
- Less energy is wasted keeping warm and moving around.
- Animals may be given feed that's higher in energy than their natural food.
- This is increase the energy input, so more energy is available for growth.
- The benefits are that more food can be produced in a shorter space of time, often at a lower costs.
- It raises ethical issues.
- Some people think that the conditions cause the animals pain, distress and restricts their natural behaviour
- This involves controlling the conditions that livestock live in, so more energy is used growth and less is used on other activities.
