Consequences of rearing feeding programme on the performance of rabbit females from 1st to 2nd parturition

Martinez-Paredes, Eugenio; Savietto, Davi; Ródenas Martínez, Luis; Cervera Fras, Mª Concepción; Blas Ferrer, Enrique; Brecchia, Gabrielle; Boiti, Cristiano; Pascual Amorós, Juan José (Cambridge University Press, 2019-10)

[EN] To evaluate how rearing programmes could affect resources allocation and reproductive performance of primiparous rabbit females, a total of 118 rabbit females were used to evaluate the effects of five rearing feeding ...
Early development and reproductive lifespan of rabbit females: implications of growth rate, rearing diet and body condition at first mating

Martinez-Paredes, Eugenio; Ródenas Martínez, Luis; Pascual Amorós, Juan José; Savietto, Davi (Cambridge University Press, 2018)

[EN] Factors influencing early development such as birth weight, nest competition, and the diet received during rearing have been proposed as elements conditioning the future reproductive performance of European rabbit ...
Early deviations in performance, metabolic and immunological indicators affect stayability in rabbit females

Penadés, M.; Arnau-Bonachera, A.; Selva, L.; Viana, D.; Larsen, T.; Corpa, J. M.; Pascual Amorós, Juan José; Savietto, D. (Cambridge University Press, 2020-04)

[EN] The main purpose of this study was to find several early factors affecting stayability in rabbit females. To reach this goal, 203 females were used from their first artificial insemination to their sixth parturition. ...
Effect of early development on semen parameters and lifespan of rabbit males selected by high growth rate

Martinez-Paredes, Eugenio; Llorens, Jorge; Ródenas Martínez, Luis; Savietto, Davi; Pascual Amorós, Juan José (Elsevier, 2019-11)

[EN] Life history theory suggests that different body development dynamics may influence survival and future reproductive performance of organisms. The present work studied how these dynamics could influence seminal traits ...
Environmental and genetic factors driving robustness in reproductive rabbit does

Savietto, Davi (Universitat Politècnica de València, 2014-04-30)

Selection strategies to increase productive traits of farm animals have been effective and highly specialized breeds and strains were obtained. At the same time, the effort made to obtain extremely high producing animals ...
Long-term implications of feed energy source in different genetic types of reproductive rabbit females: III. Fitness and productivity

Arnau-Bonachera, Alberto; Savietto, Davi; Pascual Amorós, Juan José (Cambridge University Press, 2018)

[EN] The specialization process associated with genetic selection could be associated with functional disorders, affecting the reproductive success of females (fitness). We hypothesized that by modulating energy acquisition ...
Patterns of body condition use and its impact on fertility

Savietto, Davi; Marono, Stefania; Martínez, Inés; Martínez Paredes, Eugenio Melchor; Ródenas Martínez, Luis; Cervera Fras, Mª Concepción; Pascual Amorós, Juan José (Editorial Universitat Politècnica de València, 2016-03-22)

A total of 60 nulliparous crossbred rabbit females were, a posteriori, divided into 2 experimental groups according to their natural “decision” to conceive or not at day 11 post first parturition (L: solely-lactating or ...
Rearing programmes for breeding rabbits. Effect of early development and feeding on future reproductive performance of rabbit females and males

Martínez Paredes, Eugenio Melchor (Universitat Politècnica de València, 2019-09-02)

[ES] Cualquier mejora en el conocimiento de la nutrición y el manejo de los futuros conejos reproductores debe considerarse como prioritario en la producción cunícola. Sin embargo, los principales esfuerzos en investigación ...
Reproductive robustness differs between generalist and specialist maternal rabbit lines: the role of acquisition and allocation of resources

Savietto, Davi; Friggens, Nicolas C.; Pascual Amorós, Juan José (BioMed Central, 2015-01-17)

[EN] Background: Farm animals are normally selected under highly controlled, non-limiting conditions to favour the expression of their genetic potential. Selection strategies can also focus on a single trait to favour the ...
Resources allocation in reproductive rabbit does: a review of feeding and genetic strategies for suitable performance

Pascual Amorós, Juan José; Savietto, Davi; Cervera Fras, Mª Concepción; Baselga Izquierdo, Manuel (Editorial Universitat Politècnica de València, 2013-10-01)

[EN] This article reviews how frequent feeding and selection programmes can affect resource allocation in rabbit does during reproduction. The consequences of these programmes and the central role of body condition for ...
Tawards an improved estimation of the biological components of residual feed intake in growing cattle

Savietto, Davi (Universitat Politècnica de València, 2014-03-13)

[EN] Estimated breeding values for the random regression coefficient could be useful phenotypes in themselves for studies wishing to elucidate the underlying mechanisms governing differences among animals in RFI.
Towards an improved estimation of the biological components of residual feed intake in growing cattle

Savietto, Davi; Berry, D.P.; Friggens, N.C. (American Society of Animal Science, 2014-02)

Residual feed intake (RFI) is the difference between observed and predicted feed intake. It is calculated as the residuals from a multiple regression model of DMI on the various energy expenditures (e.g., maintenance, ...
