Machine learning algorithms identified relevant SNPs for milk fat content in cattle
Ríos, Pablo J.; Raschia, Maria Agustina; Maizon, Daniel Omar; Demitrio, Daniel Arturo; Poli, Mario Andres (Sociedad Argentina de Informática, 2021-10)In recent years, machine learning methods have been shown to be efficient in identifying a subset of single nucleotide polymorphisms (SNP) underlying a trait of interest. The aim of this study was the construction of ... -
Methodology for the identification of relevant loci for milk traits in dairy cattle, using machine learning algorithms
Raschia, Maria Agustina; Ríos, Pablo Javier; Maizon, Daniel Omar; Demitrio, Daniel Arturo; Poli, Mario Andres (Elsevier, 2022)Machine learning methods were considered efficient in identifying single nucleotide polymorphisms (SNP) underlying a trait of interest. This study aimed to construct predictive models using machine learning algorithms, to ... -
Modification of a previously patented method to unequivocally score A2-like and A1-like bovine β-casein variants
Raschia, Maria Agustina; Caffaro, María Eugenia; Rossi, Ursula Amaranta; Poli, Mario Andres (Elsevier, 2023-04)A growing interest in the production and commercialization of A2 cow's milk has been observed in many countries in the last few years due to the beneficial properties for human health attributed to A2 β-casein variant. ... -
Phylogenetic relationships of Argentinean Creole with other Latin American Creole Cattle as revealed by a medium density SNP microarray
Raschia, Maria Agustina; Poli, Mario Andres (Asociación Latinoamericana de Producción Animal, 2021)The demographic history of the Criollo cattle in Argentina and in Latin America in general dates back to the time of Spanish colonization. The objective of this study was to investigate the potential use of a medium-density ... -
Potential contribution of genomics and biotechnology in animal production
Casas, Eduardo; Montaldo, Hugo H.; Nonneman, Dan J.; Poli, Mario Andres (Biblioteca Básica de Agricultura, 2015)Integration of Latin American countries into international agricultural markets requires animal production systems to be competitive. Demand of animal products is increasing due to population growth, and changes in lifestyle ... -
Preliminary genome-wide association study for skin traits in an Angora x creole backcross population
Cano Pereira, Ema Margarita; Debenedetti, Sebastián; Giovannini, Nicolas; Taddeo, Héctor Raúl; Poli, Mario Andres (Masey University (Nueva Zelanda), 2018-02)Angora goat produce mainly mohair fiber but the Creole goats have a double hair coat: cashmere, fine and short seasonal down coat and coarser and longer guard hair. Both, mohair and cashmere fiber are determined by two ... -
Quantitative trait loci exploration and characterization of gestation length in Holstein cattle
Raschia, Maria Agustina; Maizon, Daniel Omar; Amadio, Ariel; Nani, Juan Pablo; Poli, Mario Andres (Elsevier, 2024-02)Gestation length (GL) is a moderately heritable trait in cattle with economic and management implications. This study aimed to characterize the gestation length of an Argentinian Holstein cattle population, understand ... -
