Características da carne de novilhos Nelore e F1 Rubia Gallega x Nelore suplementados com cromo

open access: yesScientific Electronic Archives, 2021
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-

Use of Restricted Nursing and a Bovine Appeasing Substance on the Welfare, Growth Performance, and Response to Vaccination of Beef Calves at Weaning

open access: yesAnimal Research and One Health, EarlyView.
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.

Effect of calcium chloride injection and freezing prior to wet aging on the meat quality of cull cows

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND In Brazil, the slaughter of female cattle, particularly older animals, has increased substantially. However, meat from this category presents limitations in terms of quality, mainly because of its toughness resulting from a high concentration of cross‐links between collagen fibers.
