     of the breed for AngusPure index. This index gives commercial farmers   marbling we are rewarding those animals that are in the top 25% of the
     confidence that by using this selection tool, bulls are most likely to leave   breed for AngusPure index and who also have their marbling EBV (IMF)
     progeny with superior carcase quality and at the same time achieve   in the top 50% as well. These bulls will be awarded an ‘A+’ endorsement.
     desirable outcomes for self replacing herds, as the AngusPure index still   Marbling is one of the very highest eating quality attributes and is
     rewards cattle with strong maternal attributes like calving ease, scrotal and   necessary in order to meet some of the highest premium requirements
     growth, along with carcase weight. To qualify for the ‘A’ endorsement, bulls   for our new program, AngusPure Special Reserve. To qualify for the ‘A+’
     must meet a minimum AngusPure index of +$120.   endorsement, bulls must meet a minimum AngusPure index of +$141.
     These bulls will be => +$120 for AngusPure index.  They must also meet the minimum marbling requirement of +1.7 for IMF

                                           AngusPure recognises the need to lift the amount of marbling in our New
                                           Zealand cow genetics, in order to fill the requirements of consumers going
                                           forward. Marbling has two critical components; genetics and feeding.
                                           Feeding on a rising plane of nutrition is vital but without the genetics these
                                           attributes will not be able to express themselves.
