  13. In vitro bovine embryos production: influence of serum and hormonal supplementation

    Pinedo Merlín, M.; Ocaña Quero, J.M.; Ortega Mariscal, M.A.; Rodero Franganillo, Antonio; Moreno-Millán, M.
    On study the effect of different serum and hormonal supplements, when added to the maturation medium, on the in vitro maturation and subsequent fertilization and cleavage process of bovine oocytes. The oocyte maturation, fertilization and cleavage rates in the presence of ECS, FCS and hormonal supplements were significantly higher (p<0.001) than that obtained in the control group. No significant differences for maturation, fertilization and development were observed between the different supplements. The addition of serum and hormonal supplements to the maturation medium improved the in vitro maturation rates and subsequent in vitro fertilization and cleavage rates of bovine oocytes.

  14. An improved method for chromosome preparations from bovine oocytes and zygotes obtained by in vitro maturation and fertilization techniques

    Ocaña Quero, J.M.; Ortega Mariscal, M.A.; Pinedo Merlín, M.; Moreno-Millán, M.
    Matured bovine oocytes and zygotes obtained by in vitro maturation and fertilization techniques (IVM and IVF) were cytogenetically prepared by using an improved method for chromosome preparations. The method, which involves use of trypsinizedhypotonic solution plus a vortex-agitated system and very cold two-step fixation process, contributes to weaken the zona pellucida and allows the swelling of oocytes and zygotes which helps the subsequent spreading of the chromosomes. This method permits to obtain preparations of good quality for examining the number and morphology of the chromosomes of oocytes and zygotes for any meiotic and mitotic stage.

    The Cattle census of the Canary Islands is about 20500 animals, of this the Canary Creole Cattle Breed is only the 15.8 p.100. The other part of the census is formed by another selected breeds for milk production. Until the beginning of this decade this authochtonous breed became into danger of extinction because the competence of these imported breeds. In many cases the local population were absorbed and the total number decreased. At present, with the participation of an specific farmer association (Asociación Canaria de Arrastre) and the Official Institutions, the census are stabilised and is possible to see the...

  16. Estudio morfométrico en las variedades negras del cerdo Ibérico

    Cañuelo, P.; Molina Alcalá, Antonio; Diéguez, E.; Mata Moreno, C.; Pardo, J.; Rodero Franganillo, Antonio; Barba Capote, C.J.; Barba Capote, C.J.; Delgado-Bermejo, J.V.
    We are presenting a morphological study of the black varieties of the Iberian pig breed considering the Lampiño, Entrepelado, Mamellado, Silvela and Mamellado x Silvela strains, according to the Association of Breeders (AECERIBER) criteria. From the quantitative variables study, few significative differences among strains and sexes has been found, with absence of interactions between both factors. Also a posteriori homogeneity among means has been found significative association between strains and the frequencies of the coat colour, the types of hair, the hear type and the complementary particularities in the females, while in males a total independence have been shown.

  17. Origen e influencias del ovino canario

    Camacho Vallejo, M.E.; Fresno Baquero, M.R.; Rodero Serrano, E.; Barba Capote, C.J.; Delgado-Bermejo, J.V.
    When the Spaniards begun the conquest of the Canary Islands at the XVth Century, they found a hair sheep exploited in semi-domestic conditions, as it was written by the cronists in the seven islands. A few later, after the discovery of America, a hair sheep appeared in the Caribe. The researchers locate its origin directly in the present hair sheep of the Sub-Saharian Africa. In this paper we present some hypothesis firstly justifying the presence of hair sheep in the Canary Island, located in a latitude of wool sheep in those times. Secondly, we try to justify the sure relationship...

    Ginés, J.; García de los Ríos, A.; Barba Capote, C.J.; Delgado-Bermejo, J.V.
    In the present paper we are describing the planification of a conservation and preservation programme of the Maneto dog breed group in developing under two consecutive phases. Firstly we show the results obtained in the ethnogenetic characterization (mopho-structural and external), but also a preliminary report of the functional, genetic and environmental information collection, using a zootechnic inquiry as applications of the first phase. In the second phase we are proposing some actuation destines to the reproducers evaluation and the planification of the breeding system to develop a complete conservation programme for this breed.

  20. Plan de preservación para las variedades minoritarias de la raza canina Podenco Andaluz

    Lobo, M.; Barba Capote, C.J.; Delgado-Bermejo, J.V.
    Here we present a study about the present conservation status of all the varieties of the Andalusian Hound dog breed attending to the vulnerability criteria stabilised for the livestock species. We concluded the existence of six rare varieties in the breed; a group of three varieties (big size-short hair, small size-hard hair and small size-long hair) in a critical situation; and other three varieties (big size-long hair, midsizelong hair and small size- short hair) in vulnerability. The remaining varieties are stable or they genetic improvement is possible. Finally we propose a preservation plan of the endangered varieties attending to zootechnic,...
