This experiment was carried out to evaluate the carcass characteristics, chemical composition and fatty acid profile of the longissimus muscle of 32 young bulls from four genetic groups: Caracu; Canchin; Aberdeen Angus × Canchin; and Charolais × Caracu, finished in feedlot and slaughtered at 22 months old. Each group was composed of eight animals. There was no difference for moisture, ash, crude protein or total cholesterol between bulls from different genetic groups. However, total lipids percentage was higher for bulls […]

The objective of this experiment was to study the progesterone plasma concentrations in crossbred heifers, and the correlation with lipid metabolites concentrations. Twenty-six heifers were distributed into two treatments: T1 – treated with 500 mg sometribove zinc (recombinant bovine somatotropin) on day 3 of superovulated estrous cycle and T2 – control. The blood samples were collected during two estrous cycles: normal and superovulated one. The progesterone and metabolic lipids concentrations were determined by RIA and enzymatic method, respectively. The experimental […]
