Low Protein Rations for the Bobwhite Quail ,

Intersensory redundancy educates selective attention in bobwhite quail embryos.

We assessed whether exposure to amodal properties in bimodal stimulation (e.g. rhythm, rate, duration) could educate attention to amodal properties in subsequent unimodal stimulation during prenatal development. Bobwhite quail embryos were exposed to an individual bobwhite maternal call under several experimental and control conditions during the day prior to hatching. Experimental groups recei...

Impacts of predation on northern bobwhite and scaled quail

Antibiotic treatment of ulcerative enteritis of bobwhite quail.

Penicillin-streptomycin, bacitracin methylene disalicylate, zinc bacitracinm, soluble bacitracin methylene disalicylate, streptomycin (25%) and spectinomycin were used as prophylactic and therapeutic treatments for ulcerative enteritis in bobwhite quail (Colinus virginianus). Penicillin-streptomycin was the most effective prophylactic and streptomycin (25%) was the most effective therapeutic ag...

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...

Amino acid sequence studies on bobwhite quail egg white lysozyme.

To test the immunological prediction that there should be two amino acid sequence differences between the lysozymes of the bobwhite quail and the chicken, the sequences of these two lysozymes have now been compared. Lysozyme purified from bobwhite quail egg white was reduced, carboxymethylated, and digested with trypsin. The resulting 18 peptides were separated and their compositions determined...
