Individual differences in sexual display behaviour in the male Japanese quail

Abstract: In repeated tests we investigated the intra-individual stability and interindividual differences of courtship behaviour for 23 Japanese male quail, Coturnix c. japonica. A moving taxidermically prepared female model, and then a living female quail, were used as stimuli. Eight display units were recorded: sidedisplay, tiptoe-walking, body-shaking, nest-invitation ceremony, shoulder-featherssmoothing, up-down head movement, curtsey and flattening. During visual contact with the lure or direct encounter with a female, intra-individual stability of male courtship behaviour was noticed throughout the tests. Inter-individual differences were also observed at two levels: quantitative and qualitative. Depending on the individual, males were more or less active and/or expressed different behavioural units during courtship. Some males did not react to the lure but were clearly stimulated by the living female, whereas other ones displayed with both of the stimuli. Using correspondence analyses, several profiles of b...

Wildlife toxicity studies with oxamyl

Abstract: The acute oral LD50 of oxamyl in bobwhite (Colinus virginianus), mallards (Anas platyrhnchos) and Japanese quail (Coturnix c. japonica) is 9.4, 2.6 and 4.3 mg/kg BW, respectively. The eight-day dietary LC50 in bobwhite and mallards is 54 and 369 ppm, respectively. When Japanese quail consumed up to 33 mg oxamyl/kg BW/day over a 30-day intermittent feeding period, no effects were evident. When bobwhite and rabbits were oversprayed with oxamyl under field conditions (three times at 3 pounds per acre), no clinical or gross pathological effects were produced.

Effects of Housing and Sex on Growth Performance of Coturnix Quails in the Derived Savannah Zone of Nigeria

Abstract: This study focused on the effect of housing and sex on the growth traits of coturnix quails. A total number of 200 day-old mixed sexes quail chicks were procured for the study. The birds were separated into deep litter and cage from 3rd week of age. Sex separation was also carried out at the same time. The experiment lasted for 8 weeks and the growth traits measured on weekly basis were body weight, wing length, thigh length and breast girth. Analyzed data showed that female quails had significantly (P<0.01) superior growth rates than males across the two housing systems, that is, the former recorded higher mean values in body weight and other linear body parameters than the latter. The former also had broader breast, longer thigh and wing. These attributes could be employed in distinguishing between sexes during any breeding and selection programmes. In addition, the findings of this work reveal the superiority of cage system over that of deep litter in all the production traits evaluated. There were higher mean values in body weight of cage birds when compared with those on deep litter. It was observed that all the birds irrespective of their sexes grew in size with advancing age, although the rate of growth decreased from 7th week onwards. For increased quail meat production and regular supply of animal proteins for human consumption, female quails should be reared in large quantities and cage system of rearing should be adopted.
