The objective of this experiment was to study the development of vital organs and gastrointestinal tract of culling crossbred cows from the second (G2: 3/4Charolais (C) Nellore (N) and 3/4NC) and third (G3: 5/8CN and 5/8NC) generations of C x N rotational crossbreeding. Animals were feedlot finished and slaughtered with 465 (T465), 507 (T507), and 566 kg (T566) of body weight (BW). At the beginning of the trial, age, BW, and body condition averaged respectively, 8.5 years, 388.6 kg and, […]

The present work was carried out to evaluate the growth of stomach compartments of early weaned Holstein calves. The animals were fed concentrates and hay from the second and third week of age respectively. Eighteen animals were allotted to a completely randomized design, with three treatments (slaughter age). Six calves were slaughtered at birth, at 50 days at 110 days of age; the stomachs were withdrawn and the weight and volume of each compartment measured. Data were submitted to correlation […]
