ASIP Variants in Livestock: It's Not Black and White

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Fur and feather pigmentation play an important role in the survival and reproduction of many species, as well as in selective breeding and agriculture. The synthesis of pigment molecules, eumelanin and pheomelanin, is partially regulated by the agouti signalling protein (ASIP) encoded by the ASIP gene.

Divergent Selection for Egg Production in Coturnix coturnix japonica

Poultry Science, 1983
From a randombred control population of Coturnix coturnix japonica, strains were divergently selected for high (HE) and low (LE) 120-day egg production based on individual egg records. Based on five generations of selection, realized heritabilities for HE and LE were .063 +/- .055 and .353 +/- .020, respectively.

Pathogenicity of Coccidia in Japanese Quail (Coturnix coturnix japonica)

Poultry Science, 1984
Coccidia were recovered from a field outbreak in commercially raised Japanese quail from South Carolina. After propagation in unmedicated quail, the culture was identified as a mixture of approximately 65% Eimeria uzura, 33% E. tsunodai, and 2% E. taldykurganica. Several pure cultures of E. uzura were obtained by single oocyst isolation.
