Abstract

The objective of the experiment was to evaluate the viscera weight of steers from two genetic groups. Sixteen castrated males were utilized, being eight Nellore and eight F1 Nellore x Sind steers with 36 and 48 month of age, confined in separated boxes. Animals received the same diet and were slaughtered at average weight of 460,0 (±10,1) kg. The experimental design was completely randomized in factorial arrangement 2 (two genetic groups) x 2 (two ages). There was no interaction between genetic group and age. The age factor didn’t present difference for the characteristics studied. There was no influence of the genetic group for the weight of the digestive tract, kidneys, liver and lungs. Nellore animals presented higher weight of hearth (1,6 vs 1,2 kg) and spleen (1,1 vs 0,9 kg) than F1 Nellore x Sind cattle. It was concluded that Nellore x Sind bred product promoted reduction on hearth and spleen weight, but the ages studied don’t exert influence on viscera weight. KEY WORDS: Hearth, kidney, liver, lung, spleen.
