Impacts of predation on northern bobwhite and scaled quail

Calcium and phosphorus requirements of breeding bobwhite quail.

egg production is lowered, with the eggshells becoming pro gressively thinner. The serum calcium of the hen falls and there is a depletion of the calcium and phosphorus contents of the bones. Nevertheless, according to Branion, the percentage composition of the shell remains constant, showing that, as in bone formation, if the mineral is deposited, it is laid down in the normal proportion. Deob...

Recognition Characteristics in Covey Dialects of Bobwhite Quail

-Fifty Bobwhite quail (Colinus virginianus) were randomly divided into two equal-size coveys at six weeks of age. At 12 weeks the separation (“hoypoo”) call was recorded from birds in both coveys. Duration and frequency characters were measured and subjected to discriminant analysis. This analysis indicated that each covey could be segregated mainly on the difference in duration between the “ho...

Supplemental Chromium Yeast and / orMannan Oligosaccharides in Growing Quail Diets

To evaluatethe effects of supplementing diets of growing Japanese quails (n=450; 7 days old) with chromium (Cr) yeast and / or mannan oligosaccharides (MOS) on productive performance, carcass traits and the immune system are reported. Diets were a basal diet (control) or the basal diet supplemented with 600 mg Cr-yeast/kg (Cr 1), 1200 mg Cr-yeast/kg (Cr 2), 1.0 g MOS/kg, Cr 1 + MOS or Cr 2 + MO...
