Product Description
For the active immunisation of pregnant cows and heifers to raise antibodies against E. coli adhesion F5 (K99) antigen, rotavirus and coronavirus..
Product Information
- While calves are fed colostrum from vaccinated cows during the first 2-4 weeks of life, these antibodies have been demonstrated to:
- Reduce the severity of diarrhea caused by E. coli F5 (K99)
- Reduce the incidence of scours caused by rotavirus
- Reduce the shedding of virus by calves infected with rotavirus or coronavirus
- Intramuscular injection
- The recommended site is the side of the neck
- A single injection should be given during each pregnancy at any time between 12 weeks and 3 weeks before calving is expected
- Immunity:
- In any animal population there may be a small number of individuals which fail to respond fully to vaccination
- Successful vaccination depends upon correct storage and administration of the vaccine, together with the animal’s ability to respond
- This can be influenced by such factors as genetic constitution, intercurrent infection, age, the presence of maternally-derived antibodies, nutritional status, concurrent drug therapy and stress
- Colostrum feeding:
- Protection of calves depends on the physical presence of colostrum antibodies (from vaccinated cows) within the gut for the duration of the first 2-3 weeks of life until calves develop their own immunity
- Thus, it is essential to ensure adequate colostrum feeding for the whole of the period to maximise the efficacy of vaccination
- All calves must receive adequate colostrum from their dams within 6 hours of birth
- Suckled calves will continue to receive adequate colostrum naturally by feeding from vaccinated cows
- This product may only be sold by persons registered in terms of section 23(1)(c) of the Veterinary and Para-Veterinary Professions Act, 1982 (Act No. 19 of 1982)
