Studies with Bobwhite Quail: Reproductive Characteristics

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...

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...

Effect of Chronic V.S. Intermittent Exposure to T-2 Toxin on Reproductive Performance in Bobwhite Quail

Studies were conducted to determine the effect of chronic v.s. intermittent exposure to T-2 toxin on reproductive performance in adult bobwhite quail. In Experiment 1, 180 hens were orally dosed with 0% (LD ), 20% (LD ), 40% (LD ) or 60% (LD ) of the acute 100% lethal dose of T-2 toxin as determined in a 0 20 40 60 previous experiment. One quarter of the dosage was administered each week for 3 ...

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...
