Análisis de la duración de la gestación y de los loci que influyen sobre ella en bovinos Holando y cruzas
(Asociación Argentina de Producción Animal, 2022-11)Introducción: La intensa selección para producción lechera junto con una consideración insuficiente de parámetros de fertilidad y salud va en detrimento de estos últimos rasgos. Muchos países ampliaron los objetivos de sus ... -
Bovine leukemia virus becomes established in dairy herds before the first lactation
(2016)In this work, we studied seven groups of pregnant heifers from a consortium of dairy farms heavily infected with bovine leukemia virus (BLV). ELISA testing showed that the seroprevalence ranges of BLV in heifers between ... -
Genome-wide scan for commons SNPs affecting bovine leukemia virus infection level in dairy cattle
(2018-02-13)Background: Bovine leukemia virus (BLV) infection is omnipresent in dairy herds causing direct economic losses due to trade restrictions and lymphosarcoma-related deaths. Milk production drops and increase in the culling ... -
Genotipificación de variantes de beta-caseína bovina mediante ACRSPCR- RFLP = Genotyping of bovine beta-casein variants by ACRS-PCR-RFLP
(Consejo de Rectores de Universidades Privadas, 2023-10)Las variantes de la beta-caseína bovina pueden clasificarse en dos grupos, tipo-A1 y tipo-A2, según el aminoácido que esté presente en la posición 67 de la proteína (His, tipo A1; Pro, tipo A2)1. En los últimos años se ha ... -
Identificación de variantes alélicas de genes candidatos involucrados en producción de leche en un rodeo de bovinos de raza Holando y cruzas Holando por Jersey
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2015-07)Las razas bovinas Holando y Jersey son dos de las razas productoras de leche más importantes a nivel mundial y las principales en nuestro país. El objetivo del trabajo de tesis fue realizar un análisis exploratorio que ... -
Loci de caracteres cuantitativos para rasgos reproductivos en bovinos lecheros locales
(Sociedad Argentina de Genética, 2022-10)Introducción: La intensa selección para producción lechera junto con una consideración insuficiente de parámetros de fertilidad y salud, sumado a las correlaciones genéticas antagonistas o cercanas a cero entre caracteres ... -
Machine learning algorithms identified relevant SNPs for milk fat content in cattle
(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
(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 ... -
Potential contribution of genomics and biotechnology in animal production
(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 ... -
Quantitative trait loci exploration and characterization of gestation length in Holstein cattle
(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 ... -
Relevant loci for milk production in dairy cattle, obtained by machine learning algorithms
(Network of Women in Bioinformatics and Data Science, 2021-09)Background: Extensive genetic research focused on identifyng associations between single nucleotide polymorphism (SNP) markers located all over the genome and milk traits were conducted for different dairy cattle breeds. ... -
Single nucleotide polymorphisms in candidate genes associated with milk yield in Argentinean Holstein and Holstein x Jersey cows
(2018-12)Research on loci influencing milk production traits of dairy cattle is one of the main topics of investigation in livestock. Many genomic regions and polymorphisms associated with dairy production have been reported ... -
Weighted single-step genome-wide association analyses for milk traits in Holstein and Holstein x Jersey crossbred dairy cattle
(Elsevier, 2020-12)The purpose of this study was to identify genomic regions explaining a major proportion of the genetic variance in milk production and milk fat and protein content on a commercial herd of Holstein and Holstein x Jersey ...
