Genome‐enabled prediction of reproductive traits in Nellore cattle using parametric models and machine learning methods

17 days ago   |   By Animal Genetics

Summary
This study aimed to assess the predictive ability of different machine learning methods for genomic prediction of reproductive traits in Nellore cattle. The studied traits were age at first calving , scrotal circumference , early pregnancy and stayability. The numbers of genotyped animals and SNP markers available were 2342 and 321 419 , 4671 and 309 486 , 2681 and 319 619 and 3356 and 319 108. Predictive ability of support vector regression , Bayesian regularized artificial neural network and random forest were compared with results obtained using parametric models (genomic best...
