Prediction of rabbit meat and bone weight using measurements and sample cuts
(Institut national de la recherche agronomique (França)EDP Sciences, 1984)Regression equations predicting dissectable muscle weight in rabbits from external measurements were presented. Bone weight and weight of muscle groups were also carcass predicted. Predictive capacity of external ... -
Selection response of growth rate in rabbits for meat production
(Institut national de la recherche agronomique (França)ElsevierEDP Sciences, 1992)Genetic and environmental trends in 2 lines of rabbit (B and R) selected on individual weight gain (WG) from weaning (4 wk) to slaughter (11 wk) were estimated using mixed model methodology. Line B was derived from the ... -
Rumen digestion and urinary excretion of purine derivatives in response to urea supplementation of sodium-treated straw fed to sheep
(Cambridge University Press, 1993)The present study examined the effect of urea-N supplementation of a N-deficient diet on digestion and metabolism in the rumen. Five Rasa Aragonesa ewes, each fitted with a rumen cannula, were offered alkali-treated ... -

Endogenous purine and pyrimidine derivative excretion in pregnant sows
(Cambridge University Press, 1995)The present experiment was camed out to study the endogenous losses of purine and pyrimidine derivatives from pregnant sows. Three pregnant and three non-pregnant Large White x Landrace sows were fed on a purine-free ... -
Selection for litter size components: a critical review
(BioMed Central, 1997)The measurement of component variables such as the number of ova shed (OR) and its inclusion in a linear index with litter size (LS) or prenatal survival has been suggested in order to accelerate genetic progress for LS. ... -
Intraspecific variability of the patterns of the locomotory behaviour in terrestrial iberian anurans
(Universitat Autònoma de Barcelona. Departament de Biologia Animal, Biologia Vegetal i Ecologia, 1997)The variability in the locomotory behaviour between different species of anurans -the first vertebrates that are adapted to terrestrial environment- show the adaptive capacity of the different forms shaped by evolution. ... -
Analysis of the displacement of five iberian anuran species in stress conditions
(Universitat Autònoma de Barcelona. Departament de Biologia Animal, Biologia Vegetal i Ecologia, 1998)This study describes the movement paths -in situation of stress- of five anuran species (Alytes obstetricans, Pelobates cultripes, Bufo bufo, Bufo calamita and Bufo viridis balearicus) by trajectometric analysis. Different ... -
Excretion of endogenous and exogenous purine derivatives in sheep: effect of increased concentrate intake
(Cambridge University Press, 1998)The present study examined the endogenous urinary excretion of purine derivatives (PD; allantoin, uric acid and xanthine plus hypoxanthine) in fed animals. Four Rasa Aragonesa ewes fitted with simple cannulas in the rumen ... -
Urinary excretion of purine derivatives as an index of microbial-nitrogen intake in growing rabbits
(Cambridge University Press, 1998)Three experiments were carried out to establish a response model between intake and urinary excretion of purine compounds. In Expt 1 the relationship between the intake of purine bases (PB) and the excretion of total ... -
An expression of mixed animal model equations to account for different means and variances in the base population
(Institut national de la recherche agronomique (França)ElsevierEDP Sciences, 1999)This paper presents a general expression to predict breeding values using animal models when the base population is selected, i.e. the means and variances of breeding values in the base generation differ among individuals. ... -
Effect of selective recording on estimates of heritability
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (Espanya), 1999)En este trabajo se analiza el efecto de la selección de datos sobre las estimaciones de heredabilidad. Se estimó el valor de heredabilidad del tamaño de camada en una población porcina en la que los datos correspondientes ... -
Computation of identity by descent probabilities conditional on DNA markers via a Monte Carlo Markov Chain method
(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 ... -
Estimación de los efectos del manejo reproductivo y su influencia en la selección del tamaño de la camada en porcino
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (Espanya), 2000)Con datos procedentes de poblaciones de campo (37.920 partos porducidos en granjas de selección y 95.240 partos producidos en granjas de producción) se ha analizado la influencia de la edad al primer parto, de la duración ... -
Bayes factors for detection of quantitative trait loci
(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 ... -
Hypothesis testing for the genetic background of quantitative traits
(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 ... -
Relación entre el nivel de grasa e ingestión y la excreción urinaria de nitrógeno y energía, en gazapos en crecimiento-cebo
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (Espanya), 2001)Se determinó la excreción urinaria de nitrógeno (NU, %) y de energía (EU, kcal/100g), en la última semana de vida, de 36 conejos alimentados, desde el destete (a los 28 d) hasta el sacrificio a los dos meses de edad, con ... -
