Características da carne de novilhos Nelore e F1 Rubia Gallega x Nelore suplementados com cromo
Foram avaliadas características físico-químicas da carne de novilhos Nelore (NEL) e F1 Rubia Gallega x Nelore (RGN), suplementados com cromo picolinato (Cr), utilizando-se de amostras do M. longissimus thoracis, coletadas entre a 12ª e 13ª costelas de 24 animais. O delineamento adotado foi o inteiramente casualizado, em arranjo fatorial 2 x 2. Mensurou-

The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.
