Chlordiazepoxide and pentobarbital as tranquilizers for cowbirds and Coturnix quail

Abstract: The effects of ad libitum ingestion of chlordiazepoxide and sodium pentobarbital on penned cowbirds and coturnix quail were compared. The agents were incorporated into feed and offered to individually marked birds. Individual response to each agent appeared to relate more to the quantity of food ingested than to the percentage by weight of agent in the food. Response of both species to chlordiazepoxide was similar at the 15% dose despite weight differences of the birds. Responses were too variable to demonstrate significant differences when sodium pentobarbital at the 10% dose was given to both species. No deaths occurred among birds given chlordiazepoxide, whereas 4 quail and 1 cowbird died from sodium pentobarbital ingestion.

Circadian rhythm of activity during the annual phases in the European quail, Coturnix coturnix

Abstract: Migratory birds, such as the European quail, present an annual cycle with the following phases: moult, fattening, migration and reproduction This study aimed at determining how variations in the circadian rhythm of feeding during the annual cycle took endogenous rhythmic characteristics into account The birds (n = 8) were maintained under constant dim light from the age of 1 to 9 months Feeding activity was recorded using infra-red detectors The birds expressed all the phases, except migration Activity was arrhythmic when they were moulting A circadian rhythm of feeding activity appeared during the fattening phase In males, the circadian period lengthened and the clarity of the rhythm increased during sexual development These results appear to confirm the effects of physiological state on the temporal organisation of activity Variations of the circadian rhythm could influence the ability to synchronize with exogenous cycles such as the alternation of day and night

Pasta waste in the feeding of meat quail.

Abstract: This study was undertaken to investigate the performance, carcass characteristics, and economic viability of diets including pasta waste in meal form (PWM) for quail. A total of 450 unsexed meat quail (Coturnix coturnix coturnix) were distributed into five treatments (0, 10, 20, 30, and 40% inclusion of PWM) in a completely randomized design with six replicates, each with 15 birds. The following rearing periods were evaluated: Phase 1 - 1 to 21 days; and period of 1 to 42 days. In Phase 1, the PWM levels did not influence feed intake (FI), and the PWM inclusion levels for optimal weight gain (WG) and feed conversion (FC) were estimated at 20.70% and 22.8%, respectively. In the cumulative period of 1 to 42 days, the PWM levels did not lead to differences in FI, WG, or FC. The yields of carcass and cuts were not influenced by the treatments; however, abdominal fat yield decreased as the PWM levels in the diets were increased. Economic analysis showed a reduction of the feeding cost in the studied phases. Pasta waste meal can be included up to the level of 40% without incurring losses in the performance or carcass yield of meat quail.
