Beak-trimming methods and their effect on the performance of japanese quail pullets (Coturnix japonica)
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2006-12-01)
This study aimed at verifying if beak-trimming methods in Japanese quail pullets could optimize production by decreasing stress caused by cannibalism. A total number of 816 day-old Japanese quails was distributed in a ...
The use of carbon and nitrogen stable isotopes for the detection of poultry offal meal in meat-type quail feeds
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2013-03-01)
The objective of the present study was to trace the inclusion of poultry offal meal (POM) in the diet of meat-type quails reared for a long period using the technique of stable isotopes. A number of 320 quails were randomly ...
Experimental vaccination against Newcastle disease in Japanese quails (Coturnix coturnix japonica): Clinical and immunological parameters
(2009-02-02)
Clinical and immunological parameters of vaccinated Japanese quails against Newcastle disease were evaluated. Two-hundred and forty birds were distributed into five different experimental groups, vaccinated or not against ...
Salmonella spp. in meat-type quails (Coturnix coturnix coturnix) in the State of São Paulo, Brazil
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2013-09-01)
In the present study Salmonella spp. was surveyed in four flocks of meat-type quails reared in a farm that also had processing plant on site, located in the region of Bastos, state of São Paulo, Brazil. Meconium samples ...
Four behavioral tests associated with fear and aggressiveness in Japanese quail
Male and Female adult japanese quail (Coturnix coturnix) were evaluated in 4 tests, performed aproximately 30 days appart from each other.
Partial mechanical restraint test , Social Interaction, Tonic Inmovility and Welfare ...
Ontogeny of copulatory behaviour in male Japanese quail classified by their T-maze performance as hatchlings
(Taylor & Francis Ltd, 2008-07)
This study examines the time courses of male mating behaviours using quail that were categorised at 2 d of age as high performance (HP) or low performance (LP) individuals in a T-maze. Individually caged males from each ...
Stressor-induced changes in open-field behavior of Japanese quail selected for contrasting adrenocortical responsiveness to immobilization
(Poultry Science Association, 2006-03-01)
The effect of no treatment (undisturbed controls; CON) or 5 min exposure to immobilization stress (STR) before assessment of open-field behavior in Japanese quail lines selected for high (high stress; HS) or low (low stress; ...
Open-field temporal pattern of ambulation in Japanese quail genetically selected for contrasting adrenocortical responsiveness to brief manual restraint
(Poultry Science Association, 2008-11)
Japanese quail selected for a low-stress (LS), rather than a high-stress (HS), plasma corticosterone response to brief restraint have been shown to possess lower fearfulness and a nonspecific reduction in stress responsiveness. ...
Sociality in Japanese quail (Coturnix japonica) genetically selected for contrasting adrenocortical responsiveness
(Elsevier Science, 2002-02-04)
The growing realisation that selective breeding may offer rapid solutions to certain animal welfare problems and the associated production losses lends urgency to the search for suitable selection criteria. We have already ...
