Calf Paratyphoid vaccine is indicated to help control calf paratyphoid (salmonellosis), a severe bacterial disease in young cattle caused mainly by Salmonella dublin and S. typhimurium, preventing severe illness, and diarrhea.

DIRECTIONS FOR USE

Shake well before and during use.

• Before vaccination, the site of vaccination may be cleansed by swabbing with cotton wool dipped in antiseptic.
• Use needles of appropriate length and gauge i.e. 16-gauge 15 mm.

Dosage

Administer 2 mℓ subcutaneously. The recommended site of injection is that used for routine injection in cattle i.e. under the skin in the neck.

Vaccination Programme

• It is recommended that cows should be vaccinated twice with a 2 mℓ subcutaneous injection 3 to 4 weeks apart.
• A booster dose is given every 12 months.
• For colostrum protection, vaccinate pregnant cows approximately 8 and 3 weeks before calving.
• Calves should be fed colostrum from vaccinated dams for at least 5 days after birth.

Herd Management

In addition to vaccination with Bovilis S, the following management techniques should be employed:

• Calves should be fed colostrum from vaccinated dams mixed at a rate of 10 % diluted with milk replacer for up to 5 days after birth.
• Maintain adequate levels of hygiene throughout the farm and minimise stressful situations.
• Good calf rearing practices are essential.
• After natural challenge with Salmonella, vaccinated animals may develop mild disease but do not shed the organisms.
