Plasma Alkaline Phosphatase Activity in Mature Inbred Chickens

Disc Electrophoresis of Turkey Serum Alkaline Phosphatase Isoenzymes Using Polyacrylamide Gel

“…Stutts et al (1957) consistently observed different akp activity levels among various inbred lines of chickens. In this study zymograms II, V, VI and IX were observed only in "Vibrator" birds; conversely, zymograms VIII and XI were observed only in the Nicholas strain of turkeys.…”

“…Other reports by Auchanachie and Emslie (1934); Common (1936) and Stutts et al (1957) failed to find any correlations between egg production and total akp activity.…”

On the Relation Between the Laying Capacity and the Activity of Some Enzymes, the Level of Serum Proteins and Blood Sugar in Hens

“…Since the rate of egg production depends, among other factors, also on the capacity of the hen to deposit these minerals in the egg shells, the assessment of alkaline phosphatase activity may be assumed to be one of the decisive points in the estimation of productive capacity. Stutts et al (1957) have expressed the opinion that the specific function of alkaline phosphatase in the hen was genetically conditioned.…”

“…However, investigations were also carried out in order to establish, on the basis of the glutathione content in the blood, the relationship with the egg production. A check-up of the aforementioned properties served to establish a negative (r = -0.42) and significant correlation (Stutts et al, 1957). Pope et al (1960) found no relationship of intensity of egg production and plasma proteins.…”
