[QUOTE="Angus In Texas, post: 521809, member: 5611"] RFI stands for Residual Feed Intake - is the difference between actual feed intake and that predicted by regression, accounting for requirements of production and body weight maintenance...... in laymens terms - excess feed intake without added weight gain. Basically they are looking for animals that gain more but eat less..... thus they have a better feed conversion ratio. If bull A eats 3 pounds of feed to gain one pound and bull B eats 2 pounds of feed to gain one pound then bull B has a better feed conversion ratio and his RFI would be more negative than bull A's [/QUOTE]
