Sow body condition at weaning and reproduction performance in organic piglet production
The objective was to investigate the variation in backfat at weaning and its relations to reproduction results in organic sow herds in Denmark. The study included eight herds and 573 sows. The average backfat at weaning meanïżœ13 mm; SDïżœ4.2 mm) ranging from 10.5 to 17.3 mm among herds shows that it is possible to avoid poor body condition at weaning even with a lactation length of seven weeks or more. No main effect of backfat at weaning on reproduction performance was found, but the probability of a successful reproduction after weaning tended to decrease with decreasing backfat for first parity sows, whereas the opposite was the case for multiparous sows

Isolated defect of peroxisomal beta-oxidation in a 16-year-old patient
We describe a 16-year-old boy suffering from psychomotor retardation, sensorineuronal hearing impairment, peripheral neuropathy, hepatosplenomegaly, short stature and delayed puberty. Postnatally, muscular hypotonia, mild facial dysmorphism and delayed fontanelle closure had been noticed. At the time of our examination, adrenal cortical function was normal. Biochemical analysis revealed accumulation of very long (> C22) chain fatty acids in plasma and fibroblasts. Furthermore, elevated levels of intermediates of bile acid synthesis and phytanic acid were detectable. These findings are consistent with a defect in the peroxisomal beta-oxidation system. A generalised defect of peroxisomal function was excluded by normal plasmalogen levels in erythrocytes and normal plasmalogen de novo synthesis in fibroblasts. Immunoblotting of the peroxisomal beta-oxidation enzymes gave normal results suggesting retained immunoreactivity but catalytic inactivity of one of the enzymes involved, probably either the trifunctional protein or the peroxisomal ketothiolase. This case markedly differs clinically from the few published reports on isolated deficiencies of peroxisomal beta-oxidation. Among the patients with comparable biochemical findings, this is the first report of survival into adolescenc
