Journal ArticleDOI
Changes in feather condition in relation to feather pecking and aggressive behaviour in laying hens
Boris Bilčík,Linda J. Keeling +1 more
TL;DR: The number of severe feather pecks received was significantly related with feather damage at all ages; however, no relation with gentle feather peck received was found.
Journal ArticleDOI
Relationship between feather pecking and ground pecking in laying hens and the effect of group size.
Boris Bilčík,Linda J. Keeling +1 more
TL;DR: The results showed that most feather pecking activity occurred in the largest group size and there was some evidence of an increasing frequency of aggressive pecks with increasing group size.
Journal ArticleDOI
Behaviour when young as a predictor of severe feather pecking in adult laying hens: The redirected foraging hypothesis revisited
TL;DR: A longitudinal study on the development of severe feather pecking in individual domestic fowl using behavioural data collected from 192 individual White Leghorn hens housed continuously from hatch in 16 floor pens finds a positive association between a factor describing foraging when young and severe featherpecking when adult and a negative association.
Journal ArticleDOI
Effects of exogenous melatonin on some endocrine, behavioural and metabolic parameters in japanese quail Coturnix coturnix japonica
Michal Zeman,Pavel Výboh,Juráni M,Lamosová D,Kostal L,Boris Bilčík,Pavol Blažíček,E Jurániová +7 more
TL;DR: Melatonin administration in drinking water to Japanese quail resulted in a 20-fold increase of plasma melatonin levels in comparison with the control, day time concentration and a higher occurrence of sleeping and lower occurrence of pecking were found in melatonin treated quail.
Journal ArticleDOI
Impact of male–male competition and morphological traits on mating strategies and reproductive success in broiler breeders
Boris Bilčík,Inma Estevez +1 more
TL;DR: DNA fingerprinting results indicated that the males with the highest mating frequency did not always sire the most offspring within the group, although this lack of association may have been affected by relatively low number of males available for this study.
