Genetic Aspects of Somatic Cell Count in Holstein Dairy Cows in Iran

Animals, 2021
The aim of this study was to estimate the genetic parameters of somatic cell count (SCC) and its relationship with production traits in the first three parities in Iranian Holstein dairy cows.

Downscaling of Regional Air Quality Model Using Gaussian Plume Model and Random Forest Regression

Atmosphere, 2023
High PM10 concentrations are still a significant problem in many parts of the world. In many countries, including Poland, 50 μg/m3 is the permissible threshold for a daily average PM10 concentration.

A Bayesian Genomic Regression Model with Skew Normal Random Errors

G3: Genes, Genomes, Genetics, 2018
Genomic selection (GS) has become a tool for selecting candidates in plant and animal breeding programs. In the case of quantitative traits, it is common to assume that the distribution of the response variable can be approximated by a normal ...

A geothermal heat flow model of Africa based on random forest regression

Frontiers in Earth Science, 2022
Geothermal heat flow (GHF) data measured directly from boreholes are sparse. Purely physics-based models for geothermal heat flow prediction require various simplifications and are feasible only for few geophysical observables.

Joint multiple quantitative trait loci mapping for allometries of body compositions and metabolic traits to body weights in broiler

Animal, 2020
In order to map quantitative trait loci (QTLs) for allometries of body compositions and metabolic traits in chicken, we phenotypically characterize the allometric growths of multiple body components and metabolic traits relative to BWs using joint ...

Persistence in milk, fat and protein production of primiparous Holstein cows by random regression models Persistence in milk, fat and protein production of primiparous Holstein cows by random regression models

Revista Brasileira de Zootecnia, 2010
Total numbers of 56,508, 35,091 and 8,326 records of milk, fat, and protein test-day yields, respectively, were used to estimate genetic parameters for six persistency measures on milk, fat and protein productions of Holstein cows reared in Minas Gerais ...

Sensor-AssistedWeighted Average Ensemble Model for Detecting Major Depressive Disorder [PDF]

, 2019
The present methods of diagnosing depression are entirely dependent on self-report ratings or clinical interviews. Those traditional methods are subjective, where the individual may or may not be answering genuinely to questions.

Variable Selection and Model Choice in Geoadditive Regression Models [PDF]

, 2007
Model choice and variable selection are issues of major concern in practical regression analyses. We propose a boosting procedure that facilitates both tasks in a class of complex geoadditive regression models comprising spatial effects, nonparametric ...

Genetic (co)variance for sire fertility estimated by additive, non-additive and longitudinal models in Holstein–Zebu cross-bred cows

Animal, 2013
For this study, we used the results of sire fertility (SF) measured on a monthly basis by the ratio between the number of pregnant cows and the number of inseminations, from a total of 905 140 inseminations carried out in Cuba between 1994 and 2003 ...
