Serum Amylase Isozymes in the Japanese Quail

The Embryo Pancreas is a Source of Increased Yolk Amylase in the Fertilized Eggs of Domestic Fowls

“…2 and 3). Polymorphism of amylase in the pancreas and the serum of the Japanese quail [10], guineal fowl [8] and domestic fowl [9] are reported. Relationships of isoamylase patterns in the yolks, the pancreas and the serum of fertilized eggs or the embryos and analysis of polymorphism of amylase need further study.…”

Evaluation of Analytical Techniques for Quantification of Poultry α-Amylase

“…It is the main starch digesting enzyme in most animals (Thoma et al, 1971) and exists in at least two isoenzyme forms or isoamylases (Meites and Rogols, 1971). Recent research efforts have included measurement of serum amylase in poultry to investigate genetic variation in this trait (Watanabe et al, 1975;Washburn et al, 1980), association with other characteristics , conditions affecting growth (Moran, 1982), and other disease states (Osborne et al, 1982). Although a-amylase has been assayed for over a century, there is concern that much of the present data cannot be compared due to numerous methods of analysis (Ceska et al, 1969;Levitt et al, 1977).…”
