reared animals are animals raised by humans specifically for their meat
factory farmed animals dont have much room to move - they mat be in cages or with lots of otheranimals in the same place, this is a form of intensivefarming
animals are kept inside in warmsheds, so they dont waste much energy moving or keeping themselves warm, which means that more of their energy foes into producing meat or eggs and maximises food production
animals are sometimes given things like growthhormones or are forcefed to speed up their growth - making it even quicker and cheaper to produce meat
people are becoming more concerned that intensivelyrearedanimals dont live very nice lives, they are likely to suffer from diseases, cant behavenaturally and are killed very young
some people believe that meat from factoryreared animals dont taste as nice
