[QUOTE="WalnutCrest, post: 1372508, member: 21715"] I strongly agree with the sentiment in the sentences I bolded. Details on what we do -- simple example on three heifers, each of which are exactly 7mo old: Heifer 1 = 41.2" (FS4.0) and 530lbs Heifer 2 = 43.3" (FS5.0) and 585lbs Heifer 3 = 45.3" (FS6.0) and 575lbs Mature cows at FS4, FS5 and FS6 are supposed to be (on average) 1100lbs, 1175lbs and 1250lbs. Step 1: H1 = 530 / 1100 = 48.2% H2 = 585 / 1175 = 49.8% H3 = 575 / 1250 = 46.0% Step 2: Rank them by percentages from highest to lowest Step 3: Start making culling decisions from the bottom up until you have the number of heifers you want to retain to try to breed. This process allows me to determine which animals are achieving their final mature size most quickly, as these are the ones who are achieving their sexual maturity most quickly, and therefore will be ready to breed most easily in the time frame I want to try to breed them.
