Feed conversion ratio (FCR) is the measure of how efficiently an animal converts feed into body weight or products like milk and eggs.
It is calculated by dividing the amount of feed consumed by the weight gained or product produced. For example, if a broiler eats 2 kg of feed to gain 1 kg of weight, the FCR is 2.0. Lower FCR values mean better efficiency and higher profits.
Farmers improve FCR by giving quality feed, reducing stress, and maintaining good housing and health practices. In poultry and pig farming, FCR is one of the main indicators of farm performance.
