Mutta miksi hauraat >kanalinnun luut ovat koiralle vaarallisempia kuin >tiheämmät? luun rakenne on muuttunut ja näin ollen hänen mukaansa saattaa hajota arvaamattomalla tavalla, toisin kuin normaali luonnosta pyydystetty "luu", koska siinä on vähemmän kalkkia tukemassa sälöiksi helposti pirstoutuvaa rakennetta. Tarkemmin en pysty tätä selittämään kohtuullisen tyhmä itse olen näissä luustoasioissa lopultakin ;-), mutta tieto oli mielenkiintoinen sinänsä kun kerran asijantuntijan suusta tuli.

Author: Johanna Väisänen [ Edit | View ] Date Posted: 21:33:43 11/28/02 Thu Author Host/IP: 193.10.232.42 tässä hieman yleiskatsautta koipiluihin broilereilla: Most of the musculoskeletal problems affect the function of the locomotor system. The term "leg weakness" does not specifically imply bone weakness. However, cases of bone fracture do occur in broiler production, during catching of birds and when they are hung on shackles before slaughter. The fractures can result from weak bones or from forcing deformed limbs into the shackle. Though broilers rarely suffer from osteoporosis, maintenance of bone strength is nonetheless important in broiler production. Evidence has been obtained recently that a modern broiler strain has been showing decreased bone mineralisation and increased porosity of cortical bone that could result in more fragile and easily broken bones (Williams et al., 2000). This finding may indicate that continued genetic selection for fast growth is resulting in poorer bone quality. In a pathomorphological study on a total of 360 broiler chicken which had been random-sampled on day 22 and day 35 of the fattening period from several flocks, about 90% of the animals showed bending of the vertebral column by 20° at the height of the 6th thoracic vertebra. The L6 and L7 vertebrae were particularly affected. In numerous birds the 6th vertebra was dislocated and slightly rotated causing encroachment of the vertebral canal. Löhnert et al. (1996) assume that these abnormalities in the spine of the birds together with other disorders such as plantar pododermatitis may cause pain resulting in decreasing movements and activities.

Dillinghurst on kehittänyt BARF dietin ja hänellä on paljon käytännön kokemusta koirien ruokkimisesta pääasiallisesti lihaisilla luilla. Näin hän kirjoitti: On this subject, I have long been claiming that the very young, softer and more poorly calcified bones of modern birds are safer than the tougher and harder bones of farmyard raised chickens. This appears to be borne out in practice. Pirkko
