Se han identificado cuatro fenotipos colinesterásicos en plasma sanguineo de pollos. Para ello se han utilizado técnicas de electroforesis horizontal sobre gel de poliacrilamida. Dichos fenotipos, que coinciden con los descritos por Csuka y Petrovsky (1968) y Alvarez del Valle (1981), son designados por A, B, AB y 0. Mediante técnicas espectrofotometricas se ha cuantificado la actividad colinesterásica plasmática de estos animales, y se han encontrado diferencias significativas entre los cuatro fenotipos. La mayor actividad corresponde a la banda de migración más anódica (A), mientras que el fenotipo carente de banda electroforetica (0) presentada mínima actividad colinesterásica. Se ha observado el fenómeno de heterosis para este carácter.
Four c 1 nesterasic phenotypes in the blo plasma of chickens were identified. The technique of horizontal electrophoresis on polyacrylamide gel was used. These phenotypes also found by Csuka and Petrovsky (1968) and Alvarez del Valle (1981), are designated as A, B, AB and 0. The quantification of the colinesterasic activity was done by spectrophotometric techniques. While quantifying the colinesterasic activity, significant differences between the mean values of each phenotype were recorded. The main activity corresponded to the most anodic band A, while the phenotype 0 characterized by a lack of bands showed the minimum colinesterasic activity. We found heterosiskfor this trait.
