GENETIC RELATIONSHIP BETWEEN SERUM ALKALINE PHOSPHATASE AND BLOOD HAEMATOLOGICAL AND BIOCHEMICAL TRAITS IN MALE AND FEMALE BROILER LINES

Résumé

This study was conducted to genetically evaluate the relationship between serum alkaline Phosphatase (SAP) and blood haematological and biochemical traits of male and Jemale broiler lines at National Animal Production Research Institute (NAPRI),Shika, Nigeria. Data on blood sample were collected from twenty four birds sampled from male line, female line, male and dam control. Blood samples were taken from the wing veins of the birds and stored in heparine tubes for haematological analysis. Another blood samples were collected into non anticoagulated tube for serum analysis of Alkaline Phosphatase and other blood chemistry which include Total Protein (TP) and Acetylcholine esterase (Ach). The haematological parameters considered were pack cell volume (PCV), Haemoglobin counts (Hb) and Red blood cell (RBC). The results of this study revealed that there were significant (P<0. 05) differences in serum alkaline phosphatase except in other blood parameters where no significant differences were observed. There were positive and negative genetic correlations between serum alkaline phosphatase and blood traits measured. The measured blood fraits were positively and negatively correlated among each other. It is therefore concluded that the significant (P<0.05) difference obtained in the serum alkaline phosphatase implies that it is affected by line. High genetic correlations between serum alkaline phosphatase and blood biochemical traits are indications of linkage and pleiotropy effects among these traits. It therefore implies that, Serum Alkaline Phosphatase (SAP) can be used as a marker for selection for improved blood biochemical traits,
