El trabajo tiene por objeto dar una lectura aproximada de tres fragmentos de mosaicos, conservados en el Museo Arqueológico de Córdoba, de confusa interpretación. La autora aporta nuevos datos para la posible identificación de las figuras que decoran los medallones circulares, a través del estudio iconográfico de las mismas y de su situación en las...

Concentration of plasma insulin has been determined by radioimmunoassay in conventional and double-muscled bulls at 80 (I1), 131 (I2), 227 (I3) and 370 I(4) d of age. Double-musceld have lower plasma levels of insulin at all ages studied, which is consistent with the reduced fatty tissue of double-muscling. The correlations between insulin level an...
Nous avons suivi les taux sanguins de testostérone (T) chez des taureaux PN et BBB-V entre 1 et 12 mois d'âge. Ces animaux sont élevés à la station de Sélection Bovine de Ciney. Le sang est prélevé une fois par mois. Les résultats montrent qu'en moyenne chez les PN, les teneurs sanguines de T sont significativement supérieures à ce qu'elles sont ch...

By means of the in situ assay of deoxyribonucleases in DNA-containing polyacrylamide gels after separation by micro-disc-electrophoresis different deoxyribonucleases are detectable in bull seminal plasma. There are two groups of acid deoxyribonuclease-activities with a pH optimum at pH 5.0, one with a pH optimum at pH 7.4 and an additional one with...

1. The mean concentration of BBSP in the seminal bull plasma is 1.53 ± 0.30 mg/ml. This concentration decreases about 40% after 14 days storage at 4 °C. 2. There is only a small correlation between the concentration of BBSP in the seminalplasma and its fertilization capacity. 3. An artificial doubling of the normal BBSP concentration does not chang...
