FAQ
Frequently Asked Questions
Yes, they are essentially synonymous and often abbreviated as FCR. 'Feed conversion ratio' is the more precise and commonly used term in professional contexts, as 'feed' is the specific input.
It is critical in animal husbandry (poultry, pork, beef, dairy), aquaculture (fish and shrimp farming), and the animal feed manufacturing industry. It's a core metric for economists and sustainability experts in agriculture.
It varies by species. For example, modern broiler chickens can have an FCR around 1.5 (1.5 kg of feed for 1 kg of weight gain), which is excellent. For pigs, it might be around 2.5-3.0, and for cattle, it can be 6.0 or higher. Lower is always better for efficiency.
A lower FCR means less feed (and thus less land, water, and energy used to produce that feed) is required per unit of food produced. This reduces the overall environmental footprint of livestock production, including greenhouse gas emissions.
A technical metric measuring the amount of animal feed required to produce a unit of output (e.
