A Bayesian analysis of the effect of selection for growth rate on growth curves in rabbits
Blasco, Agustín; Piles, Miriam; Varona Aguado, Luís (BioMed Central, 2003)Gompertz growth curves were tted to the data of 137 rabbits from control (C) and selected (S) lines. The animals came from a synthetic rabbit line selected for an increased growth rate. The embryos from generations 3 ... -
Bayes factor for testing between different structures of random genetic groups: A case study using weaning weight in Bruna dels Pirineus beef cattle
Casellas, Joaquim; Piedrafita, Jesús; Varona Aguado, Luís (BioMed Central, 2007)The implementation of genetic groups in BLUP evaluations accounts for different expectations of breeding values in base animals. Notwithstanding, many feasible structures of genetic groups exist and there are no analytical ... -
Bayes factors for detection of quantitative trait loci
Varona Aguado, Luís; García Cortés, Luis Alberto; Perez Enciso, Miguel (BioMed Central, 2001)A fundamental issue in quantitative trait locus (QTL) mapping is to determine the plausibility of the presence of a QTL at a given genome location. Bayesian analysis offers an attractive way of testing alternative models ... -
Computation of identity by descent probabilities conditional on DNA markers via a Monte Carlo Markov Chain method
Perez Enciso, Miguel; Varona Aguado, Luís; Rothschild, Max Frederick (BioMed Central, 2000)The accurate estimation of the probability of identity by descent (IBD) at loci or genome positions of interest is paramount to the genetic study of quantitative and disease resistance traits. We present a Monte Carlo ... -
Effect of growth selection on morphology in Pirenaica cattle
Altarriba Farrán, Juan; Varona Aguado, Luís; Moreno, Carlos; Pastor, Francisco; Yagüe, Gema (Institut national de la recherche agronomique (França)EDP Sciences, 2006)Twelve variables were identified to define morphology in 109 calves sired by eight Pirenaica bulls widely used in artificial insemination. The effect of selection for weight at 210 days of age (W210) was detected from the ... -
Estimation of the additive and dominance variances in South African Landrace pigs
Norris, D.; Varona Aguado, Luís; Visser, D. P.; Theron, H. E.; Voordewind, S. F.; Nesambuni, E. A. (South African Society for Animal Science, 2006)The objective of this study was to estimate dominance variance for number born alive (NBA), 21- day litter weight (LWT21) and interval between parities (FI) in South African Landrace pigs. A total of 26223 NBA, 21335 LWT21 ... -
Hypothesis testing for the genetic background of quantitative traits
García Cortés, Luis Alberto; Cabrillo, Carlos; Moreno, Carlos; Varona Aguado, Luís (BioMed Central, 2001)The testing of Bayesian point null hypotheses on variance component models have resulted in a tough assigmment for which no clear and generally accepted method exists. In this work we present what we believe is a succeeding ... -
Identification of resilient sows in porcine reproductive and respiratory syndrome virus-infected farms
Abella Falcó, Glòria; Novell, Elena; Tarancón, Vicens; Varona Aguado, Luís; Pena i Subirà, Ramona Natacha; Estany Illa, Joan; Fraile Sauce, Lorenzo José (American Society of Animal Science, 2019)The identification of resilient sows can improve reproductive performance in farms exposed to multiple challenges. A common challenge is the porcine reproductive and respiratory syndrome virus (PRRSV). A key issue to deal ...
