Effect of Lactobacillus brevis ATCC 8287 as a feeding supplement on the performance and immune function of piglets.

Lactobacillus brevis ATCC 8287, a surface (S-layer) strain, possesses a variety of functional properties that make it both a potential probiotic and a good vaccine vector candidate. With this in mind, our aim was to study the survival of L. brevis in the porcine gut and investigate the effect of this strain on the growth and immune function of recently weaned piglets during a feeding trial.

Eradication of Mycoplasma hyopneumoniae from a swine finishing herd without total depopulation.

Using vaccination and medication, Mycoplasma hyopneumoniae (Mhyo) was eradicated from a finishing herd without total depopulation. Altogether 3243 feeder pigs originating from Mhyo-free herds were vaccinated once using an inactivated, adjuvanted vaccine before transporting them to a Mhyo-infected finishing herd. The Mhyo-infected groups of pigs were medicated with antimicrobial agents at the time of the arrival of the first groups of Mhyo-free, vaccinated feeder pigs.

Bioglass as a carrier for reindeer bone protein extract in the healing of rat femur defect.

Bioactive glasses have been developed as scaffolds for bone tissue engineering but combination with reindeer bone protein extract has not been evaluated. We investigated the effects of bone protein extract implants (5-40 mg dosages) with bioglass (BG) carrier on the healing of rat femur defects. Bioglass implants and untreated defects served as controls.

Case-control study of factors associated with arthritis detected at slaughter in pigs from 49 farms.

Data were collected on the housing, management and disease factors in the weaning and finishing units of 49 integrated pig herds, 24 of them with a high incidence of arthritis at slaughter (case herds) and 25 with a low incidence (control herds). A median of 5.2 per cent (range 3.
