Genetic control of residual variance of yearling weight in Nellore beef cattle
(Amer Soc Animal Science, 2017-04-01)
There is evidence for genetic variability in residual variance of livestock traits, which offers the potential for selection for increased uniformity of production. Different statistical approaches have been employed to ...
Pyrethroid residues in milk and blood of dairy cows following single topical applications
(1997-02-01)
The presence of the pyrethroid insecticides flumethrin, deltamethrin, cypermethrin and cyhalothrin in milk and blood of 10 cows was determined after single dermal applications of recommended doses. Milk and blood samples ...

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; ...
Pattern of ivermectin (sheep) and doramectin (cattle) residues in muscular tissue from various anatomical locations
(Taylor & Francis Ltd, 2008-04)
This trial reports comparative drug residual concentrations in muscular tissue obtained from various anatomical locations after subcutaneous administration of ivermectin (IVM) to sheep and topical treatment with doramectin ...
Genetic variability of residual variance of production traits in Nellore beef cattle
(Elsevier B.V., 2011-12-01)
This study was carried out to provide an exploratory analysis of genetic variability of residual variance of fifteen traits in Nellore beef cattle. The possibility of considering, simultaneously, additive and environmental ...

Genetic and environmental heterogeneity of residual variance of weight traits in Nellore beef cattle
(Biomed Central Ltd., 2012-06-06)
Background: Many studies have provided evidence of the existence of genetic heterogeneity of environmental variance, suggesting that it could be exploited to improve robustness and uniformity of livestock by selection. ...
