Pendulous Crop in Japanese Quail (Coturnix coturnix japonica)

Poultry Science, 1974
Abstract Quail chicks from a line selected for growth on a low protein (17.9%) glucose monohydrate-soybean meal diet showed a high incidence, 44.0%, of pendulous crop as compared to 11.8% in the control line fed the same ration. Substituting sucrose for glucose monohydrate did not change the incidence of pendulous crop in either the control or the ...
