Body Weight and Some Biometrical Traits of Grey Partridges (perdix Perdix) at Different Ages
NOWACZEWSKI, S., B. KOLANOS, S. KRYSTIANIAK, H. KONTECKA and M. T. GORECKI, 2014. Body weight and some biometrical traits of grey partridges (Perdix perdix) at different ages. Bulg. J. Agric. Sci., 20: 962-966 The aim of this study was to investigate the body weights, wing lengths, wingspans, tarsus lengths and third toe lengths of captive grey partridges, aged 3-15 weeks. The study was carried...
متن کاملUpland habitat use by Pyrenean grey partridges Perdix perdix hispaniensis during the breeding season
Whereas in most of Europe the decline of the grey partridge Perdix perdix is due primarily to agricultural intensification, the Pyrenean grey partridge P. p. hispaniensis is believed to suffer from the opposite effect, namely the abandonment of agricultural practices which allows the encroachment of dense shrublands. We investigated habitat use by the Pyrenean grey partridge during the breeding...
متن کاملThe influence of temperature on egg composition in the grey partridge Perdix perdix
Variations in egg size and composition can have important consequences for the quality of offspring. We investigated the effect of temperature, in the 5 days preceding laying, on yolk, albumen, shell and total egg mass. Moreover, we examined the influence of temperature on three important egg components, i.e. the yolk carotenoids and the albumen lysozyme and avidin. In our experimental conditio...
متن کاملEffects of beta-carotene supplementation on chick growth, immune status and behaviour in the grey partridge, Perdix perdix.
Carotenoids are important for various functions during chick development. Since these pigments cannot be synthesized, they can be considered limited resources that the mother optimally allocates between herself and her offspring (maternal effect). Some studies have examined the effects of carotenoids on growth and immune function but little is known about their role in behaviour. In this study ...
متن کاملLinker histone H1.b is polymorphic in grey partridge (Perdix perdix).
This study was aimed at characterizing allelic variations of erythrocyte histone H1.b by comparing the electrophoretic patterns of histone H1.b from individuals of grey partridge (Perdix perdix) population. As two alloforms, H1.b1 and H1.b2, were discerned in the screening gels, the histone H1.b was regarded to be a polymorphic protein encoded by a gene with two codominant alleles, b1 and b2, a...
