“…Class 2 is expected to contain all the phenotypically double muscled animals in our database. Three traits have been analysed in this paper: a) actual weaning weight (WW); b) preweaning average daily gain (ADG), computed as ADG = (WW-BW)/AGE, being BW the actual birth weight and AGE the age of the calf at weaning, and c) relative growth rate (RGR), defined as average daily gain relative to body weight, was computed as RGR = log (WW/BW)/AGE, being log the natural logarithm (FITZHUGH and TAYLOR, 1971;AHUNU and MAKARECHIAN, 1987) The statistical analysis was done with GLM Procedure of SAS (SAS, 1999). Sum of squares were estimated using Type III test.…”

“…Preweaning growth has usually been evaluated as average daily gain from birth to weaning using records at these ages. However, some authors have proposed to characterise the growth ability as a relative rate taking into account the average body mass (FITZHUGH and TAYLOR, 1971;AHUNU and MAKARECHIAN, 1987). 'Asturiana de los Valles' is a local Spanish beef cattle breed, exploited mostly in traditional valley-mountain grazing system in the north of Spain.…”

“…Esses resultados não estão de acordo com os encontrados por Ahunu & Makarechian (1987), que relataram maior ganho médio diário, assim como maior taxa de crescimento relativo, para os terneiros oriundos de cruzamento. O mesmo resultado foi obtido por Green et al (1991), que obtiveram maior ganho médio diário para os terneiros provenientes do cruzamento Bos taurus x Bos indicus.…”

“…Não foi encontrado efeito do SEXO sobre o PT (P>0,05), resultado esse que está de acordo com os relatados por Ahunu & Makarechian (1987), Barcellos (1989), Barcellos & Lobato (1992) e Gottschall & Lobato (1996), os quais também não verificaram efeito do sexo sobre a taxa de crescimento relativo e o ganho de peso. Ganho de peso médio (kg)…”
