Use of Principal Component Analysis to Combine Genetic Merit for Heat Stress and for Fat and Protein Yield in Spanish Autochthonous Dairy Goat Breeds

Animals, 2021
We studied the effect of the Temperature Humidity Index (THI) (i.e., the average of temperature and relative humidity registered at meteorological stations) closest to the farms taken during the test day (TD), for total daily protein and fat yields (fpy)

Random Regression Analysis of Calving Interval of Japanese Black Cows

Animals, 2021
We estimated genetic parameters for the calving interval of Japanese Black cows using a random regression model and a repeatability model. We analyzed 92,019 calving interval records of 36,178 cows. Pedigree data covered 390,263 individuals.

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 ...

GENETIC PARAMETERS FOR GROWTH PERFORMANCE TRAITS OF EGYPTIAN BARKI LAMBS USING RANDOM REGRESSION MODEL [PDF]

Arab Universities Journal of Agricultural Sciences, 2019
Variance components and genetic parameters for growth traits were estimated for Barki lambs using the average information REMLF90 (AIREMLF90). A total of 3205 Barki lambs’ records over the period from 1984 to 2017 from experimental Borg Al-Arab station ...

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 ...

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.

Admixture Mapping Reveals Candidate Regions for Methotrexate Neurotoxicity Susceptibility: A Reducing Disparities in Acute Leukemia Consortium Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Neurotoxicity is a rare, often dose‐limiting adverse effect of methotrexate (MTX) therapy that disproportionally affects Latino children. Factors contributing to the observed disparity are not well understood. This study leveraged admixture mapping to identify genetic regions associated with MTX‐related neurotoxicity susceptibility ...
