Temperament and performance of Nellore bulls classified for residual feed intake in a feedlot system [PDF]
This study aimed to evaluate the performance in feedlot and temperament of Nellore bulls classified by residual feed intake. The residual feed intake was calculated as the difference between the observed and predicted dry matter intake.

Phenotypic evaluation of feed efficiency, growth and carcass traits in native turkeys [PDF]
Improving feed efficiency decreases feed intake, total cost, and the environmental emission of poultry production. This study aimed to investigate different feed efficiency, growth and carcass traits between high and low feed efficiency birds in Iranian ...
