| dc.description.abstract | The present investigation was undertaken to identify the Serum Alkaline Phosphatase (SAP) and haemoglobin (Hb) polymorphism and also aimed to find their association with production, egg quality and reproduction. Four hundred and ninety seven hens of two different strains of White Leghorn Viz. IWP (168 and 100) and IWN (129 and 100) belonging to S15 and S16 generations, respectively were typed by Horizontal Polyacrylamide Gel Electrophoresis (PAGE). Two phenotypes, Fast and Slow were determined. Higher frequencies of Fast phenotype were observed in IWP strain (0.66 and 0.58) than IWN strain (0.15 and 0.24) in both S15 and S16 generations, respectively. Hundred hens each of IWP and IWN strains were tested for haemoglobin polymorphism with Agar gel electrophoresis, which revealed no polymorphism. Two alleles namely AkpF and Akps with two phenotypes Fast and Slow were identified as SAP locus. AkpF allele had the frequency of 0.42 and 0.35 in IWP strain and 0.08 and 0.13 in IWN strain of S15 and S16 generations, respectively. Different matings between Fast and Slow moving types revealed that the Fast band is determined by an autosomal completely dominant gene over Slow band bird. The mean SAP level for the F and S birds revealed that the SAP activity was more in F type birds (97.54 and 88.96 KA units per 100ml serum) than that of S type birds (93.03 and 68.24 KA units per 100ml serum) in both IWP and IWN strains respectively. The association between SAP types and egg quality traits revealed no significant difference between them except shell thickness. The eggs from F type birds had significantly higher shell thickness than S type in IWP and IWN strains of White Leghorn. Correlation between different SAP type matings and reproduction traits revealed that the fertility of F x F and F x S matings were highest followed by S x Sand S x F. The hatchability (on fertile egg set) was high in F x F followed by F x Sand S x F, the least hatchability was observed in S x S cross. The findings tend to conclude that the birds having gene AkpF perform better in respect of egg production, egg quality and reproduction traits. The egg production at the later stage of life was found to be high in F type birds and hence it is desirable to follow selection on extended testing periods than relying on 40 weeks egg records. | en_US |
