Frame Score Reference

Frame Score is used in the NUTBAL application to determine the animal's potential growth size.  Frame Score is based on the hip height and weight of an animal at 25 % fat content.  This level is assumed to be at a body condition score of 5.  The table below list typical frame scores for hip heights and weights for British breeds.  African breeds should refer to the zebu body condition guide located on the Publications page.  Most animals will exhibit a frame score between 1 and 6.  However,   special consideration has to be used when dealing with young, growing animals, especially those in emaciated body condition (BCS < 3).  In order for the weight/body condition score relationship to be calibrated for these animals, a lower than normal frame score must be assigned to the breedtype.  It is not uncommon to assign a  0.5 to 2 frame score for corrientes cattle imported from Mexico and be working with body condition scores of 1-3 for animals that are 12-20 months old.
