“…These lesions of the distal ulna growth plate have been considered as part of the osteochondrosis syndrome (Reiland et al., 1978; Nakano et al., 1984; Jørgensen et al., 1995; Uhlhorn et al., 1995). However, these dyschondroplastic lesions have also been considered similar to growth plate lesions found in scurvy (Holmes, 1962; Walker et al., 1966; Hanssen et al., 1979; Grøndalen and Hanssen, 1984).…”

“…Skeletal lesions typical of scurvy were described in OD‐pigs deprived of dietary vitamin C (Palludan and Wegger, 1988; Wegger and Palludan, 1994). On the other hand, no beneficial effects on bone metabolism (Pointillart et al., 1997), osteochondrotic (Nakano et al., 1983; Grøndalen and Hanssen, 1984)/ulnar dyschondroplastic lesions (Walker et al., 1966) and leg weakness (Strittmatter, 1977) have been observed in vitamin C‐supplemented commercial pigs.…”

Four litters (41 pigs) of cross-bred pigs were studied from 6 to 26 weeks of age. Blood samples were collected at 6, 13, 21 and 26 weeks of age and analysed for contents of vitamin C, calcium (Ca), inorganic phosphorus (P) and alkaline phosphatase (ALP). The pigs were examined clinically for foreleg weakness at the ages of 21 and 26 weeks. At the age of 26 weeks the pigs were slaughtered and the right forelegs were examined macroscopically and selected samples were collected for radiological, histological and ultrastructural examination. The prevalence of foreleg lesions was high, with lesions of dyschondroplasia of the distal growth plate of the ulna in 30 pigs, synovitis of the elbow joint in 24 pigs and osteochondritis dissecans of the elbow joint in 25 pigs. At the ages of 21 and 26 weeks, five pigs had evidently crooked forelegs and 14 pigs (age 21 weeks) and 25 pigs (age 26 weeks) had mildly deformed forelegs. The serum levels of Ca, P and ALP were within normal values for growing-finishing pigs. The range of vitamin C concentrations in plasma showed a wide difference (7.1-49.8 mumol/l) but was not associated with deformed forelegs. The serum concentrations of Ca, P and ALP and the plasma concentration of vitamin C differed significantly (P = 0.05) between age groups and there was a significant (P = 0.001) positive correlation between the levels of vitamin C in plasma and the serum levels of ALP at 6 weeks of age. The aim of the present study was to determine if there was any association between the plasma levels of vitamin C and the extent of crooked or deviated forelegs in growing-finishing pigs. We could not find a vitamin C deficiency during the study and no association between low levels of vitamin C in plasma and the presence of deformed forelegs of these 40 pigs.

“…The temperature of the barn was maintained at 22'C. Mechanical stress was achieved by placing an initial load of l57o of body weight in shoulder bags on the animals (Walker et al 1966 (Ali et al 1967). These were mounted and sectioned at l8 prm on a cryostat at -20"C cabinet temperature.…”

“…b) L'alimentation minérale a longtemps fait figure de principale accusée dans l'étiologie de ces troubles locomoteurs. En fait, des apports élevés ou faibles de calcium et de phosphore, associés à un apport normal de vitamine D, ne semblent pas modifier la fréquence des troubles observés (Grondalen, 1976 ;Duthie et Lancaster, 1964 ;Walker et al, 1966). Des apports phosphocalciques très élevés augmenteraient même l'incidence de la faiblesse des pattes (Berschneider, 1972 (A.R.C., 1967 ;N.R.C., 1973 ;Coalson et al, 1972 ;Cromwell et al, 1972 ;Bayley et al, 1975 ;Reinhard et al, 1976 (Pfleiderer, 1973) On peut observer (Goedegebuure, 1976) …”
