food conversion ratio的意思|示意

Food conversion ratio (FCR), also known as feed conversion ratio, is a statistic widely used in aquaculture, poultry, and livestock farming to measure an animal’s efficiency in converting feed mass into increased body mass. It is calculated by dividing the total feed mass fed to the animals over a period of time (usually weeks or months) by the increase in the animals' total body mass during that same period.

In other words, it is the industrial version of a simple calculation that many people do in their everyday lives with food; it's the ratio of how much food is eaten compared to how much weight is gained or lost. A higher FCR indicates that the animal is consuming more feed than is necessary to grow, making it less efficient and more expensive from the farmer’s perspective. Conversely, a lower FCR indicates that the animal is consuming less feed than necessary for the same amount of growth, making it more efficient.

FCR is a useful statistic for farmers and producers, as it provides valuable information about their animals’ health and efficiency. It is often used as an indicator of health and nutrition in animals, as well as a measure of the impact of different feed sources on the animals’ growth rates. Additionally, FCR can be used to compare different types of feed, as well as the results of different farming techniques, a factor which is increasingly important in the current climate of more sustainable farming practices.
