    En este trabajo se presentan los valores de los parámetros genéticos para prolificidad de la oveja Canaria de Pelo, obtenidos a partir de la utilización de un modelo animal con observaciones repetidas sobre la información generada en los núcleos de control de rendimiento cárnico de la raza. El modelo de análisis genético incluyó como efectos fijos: ganadería, año, época y número de parto; y como efectos aleatorios, el genotipo aditivo del animal y el efecto ambiental permanente. Se utilizaron, como base de información, un total de 7657 partos registrados en 2889 animales de 5 ganaderías entre los años 1996 y 2008, lo que supuso un promedio de 2,65 partos registrados por animal, suficiente para...

  2. Efecto del semental sobre las características seminales del caballo de las retuertas

    Vega-Pla, J.L.; Miró-Arias, M.; Vallecillo, A.; León Jurado, J.M.
    Geographical concentration and scarce census of the Retuertas horse force to design a complete conservation plan. One of the used tools as a mean of ex situ conservation was the creation of a germplasm bank. Previously, a study of the se-minal quality and its aptitude for freezing was developed. Results were: volume 23,25±12,72 ml; concentration 335,83±135,60x106 spermatozoa/ml; basal motility 3,83±0,98 (1-5) and progressive motility 60,42±15,42 (0-100%); all of them shown significant differences among stallions.

  12. Adaptación de Liza ramada (risso) a condiciones de baja salinidad, con vistas a la recría y repoblación en aguas dulces continentales

    Bustos Ruiz, M.; Delgado-Bermejo, J.V.
    The adaptation of Liza ramada to fresh water with low salinity (less than 1 p.100) was investigated to restock ponds and continental waters. Methods of capture, technical transport from capture site to a breeding experimental pool and the necessary arrangements are descri¬bed. After various tests with 37 samples of L. ramada w e adapted this species to the experimental conditions, since no death was observed; therefore we conclude that it is adaptable and can be easyly cultivated in fresh water.
