Titel: 
Plasmodium-associated mortality in trushes
Auteur(s):

Samenvatting: 
Since a few years acute mortality in late summer has been observed in trushes (Turdinae) kept in aviaries by bird ringers. Only fieldfares and redwings are affected. Swelling and darkening of spleens and livers are the most conspicious lesions. Sexual and asexual stadia of Plasmodium were detected cytologically in blood smears. Schizonts were found in impression smears of liver, spleen, and kidney. Incidence and pathogenesis of haematozoal infections in trushes are reviewed and compared with our findings.

Titel: 
Salmonellosis in adult cattle in Belgium

Samenvatting: 
In the summer and fall of 1999 and in May 2000, ten outbreaks of salmonellosis were diagnosed in adult beef and dairy cows in Belgium. The main clinical sign was severe, often fatal diarrhoea. Catarrhal or haemorrhagic enteritis was the main necropsy finding. Infected cows excreted large numbers of Salmonella serotype Typhimurium. Six out of seven lysotyped Typhimurium strains belonged to lysotype DT104. In contrast with the Netherlands and the United Kingdom, this type of salmonellosis in adult cattle has not been reported in Belgium before.

Titel: 
POSSIBILITIES TO LOWER THE NITROGEN AND AMMONIA EMISSIONS IN GROWING PIGS BY ADJUSTING THE FEED COMPOSITION

Samenvatting: 
Three different feeding systems were applied for each of which the protein content decreased differently in time. Urine and faeces were collected separately in metabolism cages without volatilisation of ammonia to determine the daily amount of nitrogen retained and excreted. In the stable the litter was collected after ammonia volatilisation. The samples were analysed for nitrogen. The three feeding systems did not differ in growth, feed conversion or carcass composition. The nitrogen retention was higher in gilts than in barrows. The percentage nitrogen emission through urine increased with age; the faecal nitrogen emission stayed unchanged. The reduction of feed nitrogen reduced the total nitrogen emission by the decrease of the urinary nitrogen emission. As a consequence, the potential ammonia-emission was reduced. The supply of protein-poor feed and multi-phase feeding is a valid option to lower nitrogen and ammonia emissions in growing pigs.
