An insight into population structure and genetic progress of Argentinean Holstein cattle
Pardo, Alan Maxs; Casanova, Daniel; Rubio, Natalia; Andere, Cecilia; Rodríguez, Edgardo; Corva, Pablo (Wiley, 2023-02)The objective of the present study was to investigate the most critical issues associated with the limited genetic progress evidenced in the Argentinean Holstein (“Holando Argentino”) breed in the last 20 years (only 26% ... -
Characterization of experimental cattle populations from Argentina with a low-density SNP genotyping panel
Michiels, Brian; Pardo, Alan Maxs; Ortega Masague, Maria Florencia; Giovambattista, Guillermo; Corva, Pablo (Wiley, 2022-12-05)The objectives of the present experiment were to evaluate a low-density SNP array designed for the molecular characterisation of gene banks and to assess the genetic diversity and population structure of beef cattle herds ... -
Criterios de selección por fertilidad de la hembra en bovinos para carne
Pardo, Alan Maxs (Universidad Nacional de Mar del Plata , Facultad de Ciencias Agrarias, 2017-06)El objetivo de este estudio fue identificar criterios de selección para mejorar la aptitud reproductiva de la hembra bovina. Para ello se realizaron estudios de pubertad en vaquillonas, y productividad media anual en vacas. ... -
Diferenciales de selección genética en Holando Argentino
Pardo, Alan Maxs; Corva, Pablo; Dinon, M. Anabella; Rubio, Natalia; Andere, Cecilia; Casanova, D. (Sociedad Argentina de Genética, 2020-09)La selección genética en ganado lechero a nivel global ha resultado en aumentos considerables en la productividad. En contraste, la producción de leche en Argentina se ha mantenido estable durante los últimos 20 años, aún ... -
Growth, carcass and meat quality traits in beef from Angus, Hereford and cross-breed grazing steers, and their association with SNPs in genes related to fat deposition metabolism
Papaleo Mazzucco, Juliana; Goszczynski, Daniel Estanislao; Ripoli, María Verónica; Melucci, Lilia Magdalena; Pardo, Alan Maxs; Colatto, E.; Mezzadra, Carlos Alberto; Depetris, Gustavo; Giovambattista, Guillermo; Villarreal, Edgardo Leopoldo; Rogberg Muñoz, Andres (2016)Grazing steers from Angus and Hereford breeds, their cross-breeds and a three-way cross-breed (Limousin × Angus–Hereford) were measured for growth, carcass andmeat quality traits. Breed effectswere studied, and the association ... -
Impact of the duration of rearing and finishing periods on steer performance and carcass and meat quality characteristics
Pavan, Enrique; Pouzo, Laura Beatriz; Testa, Maria Laura; Maglietti, Carlos Sebastian; Papaleo Mazzucco, Juliana; Pardo, Alan Maxs (Elsevier, 2023-08)The present study evaluates the effects of extending the rearing period on pasture for 0, 49, and 98 d (beyond 300 kg of live weight) and of finishing on a concentrate diet for 49 and 98 d on beef carcass quality, meat and ...
