Buck effect on rabbit oestrous: vulva colour, vaginal lumen cells and ovarian follicle populations

Ola, Idowu; Oyegbade, Moses (Editorial Universitat Politècnica de València, 2012-06-30)

[EN] The aim of this study was to determine the response to combinations of male stimuli in the oestrous doe in terms of changes in vulva colour, exfoliated cells in the vaginal lumen and the ovarian histology. Twelve ...
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, ...
Influence of temperature regime on endocrine parameters and vitellogenesis during experimental maturation of European eel (Anguilla anguilla) females

Pérez Igualada, Luz María; Peñaranda, D.S.; Dufour, S.; Baloche, S.; Palstra, A. P.; Van den Thillart, G.E.E.J.M.; Asturiano Nemesio, Juan Francisco (Elsevier, 2011-10-01)

[EN] We examined the effect of temperature in European silver eels during their maturation induced by injections of carp pituitary extract on endocrine parameters: pituitary fshß and lhß expression, plasma 17ß-estradiol ...
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 ...
Neuroendocrinology applied to rabbit breeding

González-Mariscal, Gabriela (Universitat Politècnica de València, 2021-12-29)

[EN] Successful rabbit production relies heavily on the use of adequate practices that enhance specific aspects of reproduction, such as mating, ovulation and lactation. Regardless of the type of production unit or strain ...
Physiology and modulation factors of ovulation in rabbit reproduction management

Mattioli, Simona; Maranesi, Margherita; Castellini, Cesare; Dal Bosco, Alessandro; Arias-Álvarez, Maria; Lorenzo, Pedro Luis; García Rebollar, Pilar; García-García, Rosa María (Universitat Politècnica de València, 2021-12-29)

[EN] Rabbit is an induced ovulatory species, so ovulation takes place after mating. Traditionally, exogenous and synthetic hormonal factors (administered by intramuscular and intravaginal route) such as GnRH and analogues, ...
Relación entre la tasa de ovulación y la supervivencia prenatal a los 25 días de gestación en conejo

Romero Ortiz, Isidro (Universitat Politècnica de València, 2016-09-09)

[ES] En este trabajo el objetivo es estudiar el efecto de la alta tasa de ovulación en el desarrollo fetal y la supervivencia prenatal a los 25 días de gestación en conejos. Se han estudiado dos grupos de hembras, hembras ...
Selection for ovulation rate in rabbits:Genetic parameters, direct response, and correlated response on litter size

Laborda Vidal, Patricia; Moce, Lorena; Santacreu Jerez, María Antonia; Blasco Mateu, Agustín (American Society of Animal Science, 2011-10)

[EN] The aim of this work was to evaluate the response to 10 generations of selection for ovulation rate. Selection was based on the phenotypic value of ovulation rate, estimated at d 12 of the second gestation by laparoscopy. ...
