Genetic association of productive traits, carcass measurements and age at first calving in the genetic evaluation of the Nellore breedNARA Subscribed
The aim was to evaluate the genetic association between sexual precocity and productive performance in Nellore cattle. Records of standardized body weights at 120 (W120), 210 (W210), 365 (W365), and 450 (W450) days of age, Longissimus Muscle Area (LMA), backfat thickness (BFT), and age at first calving (AFC) were used. The mixed linear model included the fixed effects of contemporary groups (composed of herd, year, and season...
Linear quaternion interpolation reveals globally consistent closed-circuit point cloud registrationNARA Subscribed
In the task of 3D environment mapping from point cloud registration, we face the problem of global consistency analysis in the presence of noises and a low overlap rate. Significant errors in the registration result in less consistent environment maps. This study aims to present a linear interpolation method for consistent terrestrial laser scanning data registration to overcome the drift problem from pairwise registration err...
Reaction norm models for the evaluation of reproductive and productive performance in Nellore cattleNARA Subscribed
This study evaluated genotype × environment interactions (G×E) in Nellore cattle for growth, reproductive, and carcass traits using reaction norm models. We analyzed the records of body weight and scrotal circumference at 12 and 18 months. (W365, W450, SC365, SC450), as well as loin eye area (LEA) and subcutaneous fat thickness (SFT), from herds across different Brazilian states were analyzed. A hierarchical one-step reaction...
