ABSTRACT The objective of the present study was to evaluate the stability of candidate reference genes and select the genes that can be used for normalizing real-time polymerase chain reaction (PCR) in the liver, skeletal muscle, and jejunum tissues of Nellore or Nellore × Angus steers fed different diets. Fourteen purebred and 14 crossbred steers were used, in which half of the animals of each genetic group received a diet containing whole shelled corn (WSC) and the other half whole […]

The research aimed to analyze the effects of feed restriction prior to the confinement on growth and chemical composition of the tissues and organs in cattle. Twenty-four Holstein-Gyr crossbred steers, with 19,3 ± 5,1 months of age and 202,1 ± 49,1 kg LW, at beginning of the trial were used. Fifteen of the animals were confined after a 104-day period of forage restriction, in which it was intended to keep body weight unchanged (compensatory gain group), while nine of them […]
