(Springer, 2014-07-15)Citrus canker, caused by the bacterium Xanthomonas citri pv. citri (Xcc), is an endemic quarantine disease in northeastern Argentina. The objective of this study was to quantify the effect of weather variables on mid-season ... -
Quantifying the negative impact of clinical diseases on productive and reproductive performance of dairy cows in central Argentina
(Elsevier, 2022-03-15)In dairy herds, cattle experience different health disorders, and their occurrence during lactation may cause important economic losses. The systematic analysis of productive and health records allows us to identify the ... -
Quantitation of cytokine gene expression by real time PCR in bovine milk and colostrum cells from cows immunized with abovine rotavirus VP6 experimental vaccine
(Elsevier, 2013-10)In a previous work, VP6 recombinant protein was produced using baculovirus system and it was evaluated in a colostrum-deprived calf model. This vaccine was able to protect calves against viral challenge without inducing ... -
Quantitative genetic parameters for growth and wood properties in Eucalyptus “urograndis” hybrid using near-infrared phenotyping and genome-wide SNP-based relationships
(2019-06-24)A thorough understanding of the heritability, genetic correlations and additive and non-additive variance components of tree growth and wood properties is a requisite for effective tree breeding. This knowledge is essential ... -
Quantitative genetics and genomics converge to accelerate forest tree breeding
(2018-11)Forest tree breeding has been successful at delivering genetically improved material for multiple traits based on recurrent cycles of selection, mating, and testing. However, long breeding cycles, late flowering, variable ... -
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 ... -
Que pasará con las lluvias en primavera y en verano.
