Lameness is a severe welfare problem and a production-limiting disease in dairy farming. The objectives of this study were to determine prevalence of lameness and investigate cow- and herd-level factors associated with lameness in dairy cows housed in freestall barns in 3 Canadian provinces. A purposive sample of 40 Holstein-Friesian cows was selected from each of 141 dairy farms in Québec, Ont...

BACKGROUND Migration of a rigid gas permeable (RGP) contact lens after trauma is rare, and its clinical characteristics have not been fully discussed. CASE PRESENTATION A 36-year-old female showed mild swelling in the right upper eyelid. She lost her RGP contact lens seven months prior to her first visit, from trauma by her child's kick to the right eye. At the first examination, we felt a fi...

Ectropion is a turning outward of the free border of the eyelid, resulting in exposure of the conjunctiva [1]. It is classified in the following categories: congenital and acquired, which may be involutional, paralytic, cicatricial and mechanical [2,3]. Tarsal ectropion is a clinical condition characterized by lower lid eversion which is limited to the tarsal-containing portion alone [4,5]. It ...

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...

Members of the family Bdellidae inhabit a variety of habitats worldwide and are active predators of small arthropods_ Studies by Muma (1975) indicated that Bdella distincta (Baker & Balock) prey on eggs and crawlers of armoured scale insects on citrus in Florida, while Neomolgus capil/atus (Kramer) is associated with pasture pests from Scandinavia to Morocco (Wallace 1974). Bdellodes lapidaria ...

Using museum specimens collected in Israel during the second half of the 20th century, no support was found for the hypothesis that body mass and tarsus length of chukar partridges Alectoris chukar has changed as a result of global warming. Body mass showed ̄uctuations during the year, reaching a maximum in late winter and spring and a minimum in summer. Bergmann's rule predicts that in warmblo...

AlaSTRACT.--Sexual wing dimorphism in relation to tail ornaments and body size was studied in the strikingly sexually dimorphic widowbirds and bishops (Euplectes) of the African tropics. Seven widowbirds grow long tails, varying from 7 cm in Fan-tailed Widowbird (E. axillaris) to 0.5 m in the Long-tailed Widowbird (E. progne). Aerodynamic drag increases with tail length, and adaptations to comp...
