1. Colostrum: Calves should receive colostrum within the first 12 to 24 hours of life. Colostrum is the first milk produced by the cow after giving birth, and it contains important antibodies that provide the calf with immediate protection against diseases.
2. Respiratory Vaccines: Respiratory vaccines, such as those for bovine respiratory syncytial virus (BRSV), parainfluenza-3 (PI-3), and bovine viral diarrhea (BVD), are often given to calves at 2 to 4 weeks of age. A second dose of these vaccines may be given 2 to 4 weeks later.
3. Scours Vaccines: Scours vaccines, which protect against diarrhea-causing pathogens such as rotavirus and coronavirus, are typically given at 2 to 4 weeks of age. A second dose may be given 2 to 4 weeks later.
4. Clostridial Vaccines: Clostridial vaccines, which protect against diseases such as blackleg, tetanus, and malignant edema, are often given at 3 to 8 weeks of age. A booster vaccination may be given 4 to 6 weeks later.
5. Leptospirosis Vaccine: The leptospirosis vaccine protects against bacterial infections that can cause abortions, infertility, and other health issues in cattle. It is usually given at 4 to 6 weeks of age, followed by a booster vaccination 4 to 6 weeks later.
6. Bovine Viral Diarrhea (BVD) Vaccine: BVD is a common and economically significant viral disease in cattle. The BVD vaccine is often given at 2 to 4 weeks of age, followed by a booster vaccination 2 to 4 weeks later.
It's essential to follow the vaccination schedule recommended by your veterinarian or local animal health authorities to ensure that your newborn calves receive adequate protection against common diseases.
