This trial aimed to investigate the influence of calf genetic group on the ingestive behavior of Nellore dams and their offspring on pasture. Twenty one primiparous and multiparous Nellore cows were assigned to the experiment; 13 cows nursed straightbred Nellore calves; and eight cows nursed halfbred Simmental × Nellore calves.

ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

PSXIV-9 Effect of fiber level on the performance of Nelore and ½ Angus-Nelore cattle.
Abstract Diets with high grain inclusion have become increasingly common in Brazilian feedlots. Data from our laboratory (Caetano et al., 2015) demonstrated that the feed intake of purebred Nelore cattle was maximized only at fiber levels above 11% neutral detergent fiber from forage (fNDF).
