Abstract

Hip height records of yearling males and females (n=3.948), and from breeding cows (n=6.174) of Nelore breed, reared at the Estação Experimental de Zootecnia de Sertãozinho, Brazil, were used to study the viablility equations and tables published by Beef Improvement Federation (2006) viability to obtain frame scores. It was observed a high frequency of frames ranging from 6 to 7 for young animals and from 7 to 9 for cows, characterizing these animals as large, but not of extreme in size. However, the majority of the cows changed their frame with the age. Cow body weight, by frame score, was smaller than those cited in the literature for the European breeds. The female frame score repeatability estimates (0.76) and heritability (0.58) were high, however, they were smaller than hip height repeatability (0.84) and heritability (0.67) estimates.
