 And it takes typically something like 2.6 kilograms of that feed to produce just one kilogram of chicken. This is a really important statistic that's used across the board in animal farming, the feed conversion ratio or FCR. Basically, how many kilos of feed do you have to put into an animal in order to get one kilo of meat out? High intensity chickens have a much lower FCR, but the longer they live, the higher that number goes.
