Pfizer Animal Health, Veterinary Medicine Research and Development, Sandwich, United Kingdom Outbreaks of bovine respiratory disease most frequently occur in young animals. Due to the high prevalence of maternal antibodies against Bovine Respiratory Syncytial Virus (BRSV) and Parainfluenza Type 3 Virus (PI3V), systemic two-dose vaccination of calves below three months of age often induces insufficient protection against these viruses. In this study, a vaccination schedule comprising intranasal vaccination with a modified live BRSV and PI3V vaccine at three weeks of age followed by systemic booster vaccinations with modified live vaccine at three and four months of age was evaluated in calves with and without maternal antibodies. Calves were either vaccinated intranasally (Rispoval ® RS+PI3 IntraNasal, Pfizer Ltd) at three weeks of age followed by booster vaccinations intramuscularly (Rispoval ® 3, Pfizer Ltd) at three and four months of age, vaccinated intranasally at three weeks of age only, vaccinated intramuscularly at three and four months of age only or not vaccinated at all. The same experiment was carried out in calves with and without maternal antibodies. Blood samples were collected weekly until four weeks after the second booster and BRSV and PI3V serum antibody levels measured by ELISA. In calves without maternal antibodies intranasal vaccination induced high serum antibody levels to BRSV and PI3V. The booster injections were necessary to prevent antibody levels for PI3V declining from nine weeks and BRSV from 14 weeks after intranasal vaccination as observed in calves that did not receive the boosters. Antibody responses to both BRSV and PI3V after the first intramuscular vaccination at three months of age were higher in calves vaccinated earlier with the intranasal vaccine compared with calves that only received their first vaccination at three months of age. In calves with maternal antibodies there was no increase in BRSV or PI3V serum antibody levels after intranasal vaccination. However, after the first booster again higher antibody levels were measured in calves earlier vaccinated intranasally compared with calves that had not been vaccinated before. BRSV and PI3V antibody levels of calves that were not given booster vaccinations continued to decline beyond three months of age. Based on the serological monitoring carried out in this study, it was concluded that intranasal followed by systemic vaccination is an optimal vaccination schedule for young calves against BRSV and PI3V. 273 Case Control Study for the Evaluation of Risk Factors Associated with Infectious Respiratory Diseases in Dairy Calves in Québec D.

Arsenault 1 1 Université de Montréal, Clinical Sciences, St-Hyacinthe, Canada 2 Laboratoire d’Épimiosurveillance Animale du Québec, Clinical Sciences, Saint-Hyacinthe, Canada 3 Fédération des Producteurs de Bovins du Québec, Longueil, Canada A case control study was performed to evaluate the risk factors associated with infectious respiratory diseases in dairy calves in Québec.Twenty eight herds were selected as control based on absence of respiratory diseases in calves during the last 24 months. Fourteen herds were selected as case based on the history of endemic respiratory problems. All herds were visited twice at 1 month interval. In all herds, 5 calves of less than 6 month of age were randomly selected. Blood samples were taken to evaluate IBR, BRSV, PI-3, BVD and Mycoplasma bovis for serology. Nasal swabs were preformed during the 1st visit for viral isolation, mycoplasma and routine bacterial culture. Milk bulk tank was sampled twice for mycoplasma culture. A questionnaire on herd practice was submitted to the herd manager and veterinarian. Statistical analysis was performed for the following risk factors: viral, bacterial and mycoplasma status, herd size, calf feeding practice, calves vaccination program and contact between animals. Exact conditional logistic regression stratified for the matched pair was used. All factors were tested in univariate analysis. Variables with P
Materials and Methods: 90 healthy naturally born calves, 45 Nelore and 45 Limousin, were grouped according to their dam’s parity. Venous blood samples were collected from the 90 calves within the first 24 to 36 hours of life, and at 15, 30, 60, 90, and 120 days post-natal. Samples Results: The parity of the dam had no effect on mean values of serum gammaglobulins, serum and plasma proteins, and serum activity of gamma-glutamyl transferase (GGT) in calves within 24 to 36 hours of life. Although the serum gammaglobulins did not differ significantly between breeds, Nelore calves showed slightly higher serum and plasma proteins, IgG, significantly higher GGT (p
