Crossbreeding parameters of some productive traits in meat rabbits

Piles, M.; Rafel, O.; Ramon, J.; Gómez, E.A. (World Rabbit Science. ICTA. UPV, 2004)

[EN] A crossbreeding experiment using animals from C and R rabbit strains was conducted. Direct and maternal additive genetic effects and direct heterosis were estimated for some productive traits during the post-weaning ...
Genome wide association study of growth and feed efficiency traits in rabbits

Garreau, Hervé; Labrune, Yann; Chapuis, Hervé; Ruesche, Julien; Riquet, Juliette; Demars, Julie; Benitez, Florence; Richard, François; Drouilhet, Laurence; Zemb, Olivier; Gilbert, Hélène (Universitat Politècnica de València, 2023-09-28)

[EN] Feed efficiency is a major production trait in animal genetic breeding schemes. To further investigate the genetic control of feed efficiency in rabbits, we performed a genome-wide association study (GWAS) for growth ...
Individual efficiency for the use of feed resources in rabbits

Piles, Miriam; García-Tomas, M.; Rafel, O.; Ibañez Escriche, Noelia; Ramon, J.; Varona, L. (American Society of Animal Science, 2007-11)

[EN] A Bayesian procedure, which allows consideration of the individual variation in the feed resource allocation pattern, is described and implemented in 2 sire lines of rabbit (Caldes and R). The procedure is based on a ...
Involvement of the Melanocortin System in the Regulation of Circadian and Behavioural Mechanisms in Zebrafish

Godino Gimeno, Alejandra (Universitat Politècnica de València, 2024-03-14)

[ES] El sistema de melanocortina es una estructura clave en la regulación de una amplia gama de funciones fisiológicas que incluyen la melanogénesis, la respuesta al estrés y el equilibrio energético, mediante la unión a ...
New insights for enhancing feed efficiency

Mora Fenoll, Mónica (Universitat Politècnica de València, 2025-09-27)

[ES] La tesis abarca una serie de estudios destinados a mejorar los programas de selección genética para aumentar la eficiencia alimentaria en dos etapas de la vida productiva de los cerdos: lactación y crecimiento. En los ...
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, ...
