The work was carried out to evaluate the to growth in kg and in relation to live weight (% LW) and to empty body weight (% EBW) of the viscera and other corporal components with increase of the age of Holstein male calves. Eighteen animals distributed in three slaughter age (six at birth, six at 50 days and six at 110 days of age), weighing between 30 and 100 kg LW or 27.57 and 74.27 kg EBW were slaughtered. After […]

Twelve crossbred Texel x Bergamácia (TB), 12 crossbred Texel x Santa Inês (TS) and 12 purebred Santa Inês (SI) lambs were individually finished in fedlot for 50 days (from 130 to 180 days of age). Each genetic group consisted of six males and six females, fed three different diets: 1 = without coffee hulls (control); 2 = with coffee hulls in nature; 3 = with coffee hulls treated of with urea. The rumen/reticulum (RR) of the animals fed diets 1 […]
