Genetics and genomics of uniformity and resilience in livestock and aquaculture species: A review
(2020-05-01)
Genetic control of residual variance offers opportunities to increase uniformity and resilience of livestock and aquaculture species. Improving uniformity and resilience of animals will improve health and welfare of animals ...
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. ...

Genomic regions underlying uniformity of yearling weight in Nellore cattle evaluated under different response variables
(2018-08-16)
Background: In livestock, residual variance has been studied because of the interest to improve uniformity of production. Several studies have provided evidence that residual variance is partially under genetic control; ...
Estimation of segregation variance for birth weight in beef cattle
(Elsevier, 2002-08)
Genetic evaluation using multibreed covariance theory requires estimating the segregation variance. The segregation variance is the amount by which the additive variance in the F2 exceeds that in F1. The goal of this ...

Environmental light color affects the stress response of Nile tilapia
(2013-02-01)
We investigated the effects of environmental light colors (blue, yellow and white) on the stress responses (measured by changes in ventilatory frequency - VF) of Nile tilapia to confinement. After 7 days of light treatment, ...
