      Peinado Lucena, E.; López, I.; Gallego Barrera, J.A.; Zamora Lozano, Miguel (Universidad de Córdoba, Servicio de Publicaciones, 1987)
      A study on the growth of young lactant rabbits from mothers reared under extensive system of continuous grazing has been carried out. The results show an average litters, in spite of intensive rhythm of reproduction, of ...

    • Desarrollo del Cistus ladanifer L. tras su corte mecánico 

      Peinado Lucena, E.; Gallego Barrera, J.A.; Sánchez Rodríguez, M.; Mata Moreno, C.; Zamora Lozano, Miguel (Universidad de Córdoba, Servicio de Publicaciones, 1985)
      A study on development and production of Cistus ladanifer L. has been carried out. The plants mere one and two years old. The total weight of the leaves compared to the total weight of the plant is 78 % in the first year! ...

    • Empleo de diversas dimensiones de la planta en la predicción de su peso y masa foliar: aplicación a Cistus ladanifer L. 

      Gómez-Castro, A.G.; Megías Rivas, M.D.; Sánchez Rodríguez, M.; Gallego Barrera, J.A.; Martínez Teruel, A. (Universidad de Córdoba, Servicio de Publicaciones, 1987)
      Regression equations between several plant measures and total or foliar weight of plants of Cistus ladanifer were fitted. Although multiparameter equations account for most of observed variation in total weight, the ...

    • Estudio comparativo de diferentes aditivos en el ensilado del subproducto de naranja 

      Gallego Barrera, J.A.; Megías Rivas, M.D.; Sánchez Rodríguez, M.; Martínez Teruel, A. (Universidad de Córdoba, Servicio de Publicaciones, 1992)
      The addition of 4% formic acid, dry beet pulp or sodium chloride to a orange by product do not improve the silage quality, after 100 days of conservation.

    • Influencia de factores geotopogríficos sobre la composición química de Cistus ladanifer L. 

      Peinado Lucena, E.; Martínez Teruel, A.; Gómez-Castro, A.G.; Sánchez Rodríguez, M.; Gallego Barrera, J.A. (Universidad de Córdoba, Servicio de Publicaciones, 1987)
      Significative influences of several geotopographic characteristics are shown on a concentration of crude nutritive principles and mineral elements in C. ladanifer but a clear regulation of these observations is not discernible.

    • Modificaciones del componente foliáceo y tamaño en plantas de Cistus ladanifer L. 

      Martínez Teruel, A.; Gallego Barrera, J.A.; Megías Rivas, M.D.; Alcalde Leal, J.L.; Gómez-Castro, A.G. (Universidad de Córdoba, Servicio de Publicaciones, 1988)
      During the growing, th eafy fraction of C. ladanifer decreases and leaf dry matter increases. High correlation coeficients with plant size are obtained in this way. The meaning of these modifications is discussed.
