[QUOTE="rocket2222, post: 470163, member: 5362"] A contemporary group is made up of animals that are raised exactly the same way. If pick out 20 heifers for replacements out of a group of 100 heifers. Then you feed those 20 replacements grain, and the 80 heifers that are left are just left to graze your pastures untill they are big enough to sell to someone. You have made 2 contemporary groups. the 20 replacements you are feeding grain, and the 80 that are only getting grass. You would not want to have the calves on grain compared to the calves that just eat grass, it would not be a fair comparison. Thats why they are split in to different groups. [/QUOTE]
