Tuyển tập báo cáo các nghiên cứu khoa học quốc tế ngành y học dành cho các bạn tham khảo đề tài: Electrophoretic serum in dwarf and normal and their correlations with . EL-ATTAR protein fractions layer hens productive traits | Génét. Sél. Evol. 1985 17 2 283-290 Note Electrophoretic serum protein fractions in dwarf and normal layer hens and their correlations with productive traits . EL-ATTAR and . RASHD Animal Production Department Genetics Department Faculty of Agriculture A in Shams University Cairo Egypt Summary Normal and dwarf Fayoumi-cross layers aged 43 weeks belonging to 7 sire families were compared for serum protein profiles using a Polyacrylamide gel electrophoresis technique. Phenotypic correlations between serum protein percentages and productive traits were estimated. The results were as follows 1. Albumin p. 100 for dwarf layers represented p. 100 of that of the normal ones p . 2 Dwarf layers had significantly higher fc-globulin p. 100 p than their normal counterparts. 3. Total globulin p. 100 was higher for dwarf layers than for the normal ones vs respectively p . 4. Sire family effect was only significant for Yi-globulin p. 100 while the sire family X genotype interaction did not show any significance for serum protein percentages. 5. Most of the phenotypic correlations of serum protein percentages with productive traits were insignificant. Ya-globulin p. 100 was negatively correlated with body weight at 8 weeks of age. Key words Fowl dwarfism serum protein egg production. Resume Fractions électrophorétiques des protéines du serum Chez des pondeuses naines et normales et leurs correlations avec des caractères économiques Des poules pondeuses normales et naines d un croisement Fayoumi âgées de 43 semaines appartenant à 7 families de pères ont été comparees pour la proportion des proteines sệrịques en utilisant la technique d electrophorese en gel de polyacrylamide. Les correlations phénotypiques entre les pourcentages des diverses classes de protéines du serum et les caractères de production etaient estimes. Les résultats sont les suivants 284 . EL-ATTAR .
