This change comes out by the fact that CV% rated very high already means a high variability.
In table 2 we have the classifications for CV% based on GARCIA (1989) and COSTA et al.
For example, weight gain was classified low CV% if less than 12% (or 11%), medium CV% if between 12% and 20%, and high CV% if bigger than 20% (Table 2).
In the intake category of variables CV% the limit between low and medium rate was 4%, while for JUDICE et al.
(1999), classifying CV% for pigs, we have the categories weight gain, feed conversion, feed intake and carcass yield.
In general, both range of the CV% as the boundaries between the categories of classification, in this study, are lower than those proposed by GOMES (1985), noting that this study did not consider categorizing CV% as very high.
