Análise de componentes principais para características de crescimento em bovinos de corte
(Univ Estadual Londrina, 2014-01-01)
The objetive of this research was to study the relation among body weight and average daily gain in different ages, using principal components analysis. Data on 1663 birth weight (BW), weaning weight adjusted to 230 days ...
Association among residual feed intake, residual body weight gain, residual intake and body weight gain and temperament of Nellore cattle
(2014)
A study was conducted to investigate association among residual feed intake (RFI), residual body weight gain (RG), residual intake and body weight gain (RIG) and temperament of Nellore (Bos indicus) young bulls (n = 44; ...

(Univ Estadual Londrina, 2015)
Long-term weight gain and economic impact in pigs castrated under local anaesthesia
(2016-12-01)
Castration is a controversial practice in swine production because in some countries is still performed without anaesthesia, and therefore causes intense suffering and stress to animals. This study investigated the effect ...

Estimation of genetic parameters for weight traits and Kleiber Index in a Brahman cattle population
(Univ Sao Paolo, 2019-11-01)
Interest in improving feed efficiency of cattle has been increasing. The residual feed intake (RFI), the most commonly used measurement of feed efficiency, is expensive and can only be used in a small number of animals. ...
