Correlated responses on litter size traits and survival traits after two-stage selection for ovulation rate and litter size in rabbits

Badawy Elmoghazy, Ahmed Yehia; Peiró Barber, Rosa Mª; Blasco Mateu, Agustín; Santacreu Jerez, María Antonia (Cambridge University Press, 2019-03)

[EN] Farmer profit depends on the number of slaughter rabbits. The improvement of litter size (LS) at birth by two-stage selection for ovulation rate (OR) and LS could modify survival rate from birth to slaughter. This ...
Efecto del cultivo in vitro y de la vitrificación de embriones en la supervivencia y desarrollo prenatal y crecimiento postnatal en el conejo

Villamayor Llorens, Marina (Universitat Politècnica de València, 2018-12-19)

El uso de técnicas de reproducción asistida tanto en medicina humana, como respuesta a los problemas de fertilidad, como en animales, como forma de difusión de la mejora genética y preservación de recursos genéticos, ha ...
Effect of Embryonic and Maternal Genotype on Embryo and Foetal Survival in Rabbit

Vicente Antón, José Salvador; Llobat, L.; Jiménez Trigos, María Estrella; Lavara García, Raquel; Marco Jiménez, Francisco (Wiley, 2013-06)

[EN] The aim of this work was to study the influence of embryonic and maternal genotype of two lines of rabbits selected by growth rate (line R) and litter size at weaning (line A) on prenatal survival. Embryos were recovered ...
Environmental and Genetic Factors Affecting Litter Size Components in Rabbits

Belabbas, Rafik; Ilès, Imèn; Argente, María-José; Ezzeoug, Rym; Ainbaziz, Hacina; García, María-Luz (Universitat Politècnica de València, 2023-06-30)

[EN] In rabbits, ovulation rate is, together with prenatal survival, one of the main limiting factors for litter size. Both components are affected by several factors related to females and their environment. Thus, ...
Litter size component traits in two Algerian rabbit lines

Belabbas, Rafik; García, Maria de la Luz; AinBaziz, Hacina; Berbar, Ali; Argente, Maria José (Universitat Politècnica de València, 2021-03-31)

[EN] The aim of this study was to estimate the limiting litter size components in rabbit females from a Synthetic line (n=32) and a Local population (n=34). Ovulation rate, number of implanted and live embryos were counted ...
Litter size components in a full diallel cross of four maternal lines of rabbits

Mohamed Ragab, Mohamed; Sánchez Serrano, Juan Pablo; Mínguez Balaguer, Carlos; Vicente Antón, José Salvador; Baselga Izquierdo, Manuel (American Society of Animal Science, 2014-08)

[EN] A crossbreeding experiment between 4 Spanish maternal lines of rabbits was performed to estimate crossbreeding effects on litter size components. The experiment was designed as a complete diallel cross involving 4 ...
Selection for ovulation rate in rabbits

Laborda Vidal, Patricia (Universitat Politècnica de València, 2011-12-23)

El objetivo de esta tesis ha sido estudiar la respuesta directa a la selección por tasa de ovulación en conejo y las respuestas correlacionadas en tamaño de camada y tasas de supervivencia. Los animales pertenecían a una ...
