When choosing a meat animal for your homestead you may begin wondering, “What animal will get me the most bang for my buck?”
Each animal uses feed differently, and some are able to turn that feed into pounds of meat more efficiently than others. This is usually expressed by what’s called a feed conversion ratio. Feed conversion ratios are a rate of measure that expresses the efficiency with which an animal converts feed into the desired output. For cattle, broiler chickens and pigs, the desired output is body mass. For dairy cows, the desired output is milk. For the purposes of this article, we are just going to focus on animals where the desired output is body mass, or pounds of meat.
The mathematical formula for a feed conversion ratio is as follows: FCR = feed given / animal weight gain.
This feed conversion ratio (FCR) is typically expressed as one number and is dimensionless, meaning it is not effected by whatever units of measure are used to calculate the ratio. A low FCR means that the animal is efficient at converting feed to the desired output, while a higher FCR means the animal is relatively inefficient.
