Cow Vaccination During Pregnancy
Importance of Cow Vaccination During Pregnancy
Ensuring a healthy pregnancy for cows and heifers requires proper vaccination. Diseases such as Bovine Viral Diarrhea (BVD) and Leptospirosis can cause abortion and significant economic loss. Farmers must follow a structured vaccination schedule to protect their herds and prevent infections.

Key Vaccinations for Pregnant Cows
Core Vaccines for Pregnant Cattle
Vaccines are crucial in preventing reproductive diseases. Below are essential vaccines:
Bovine Viral Diarrhea (BVD)
BVD is a highly contagious virus that can cause infertility, stillbirths, and weak calves. Vaccination before breeding reduces risks.

Leptospirosis
Leptospirosis spreads through contaminated water and urine. It leads to abortion storms in herds. Annual vaccination, especially before pregnancy, helps control the disease.

Infectious Bovine Rhinotracheitis (IBR)
IBR causes respiratory infections and reproductive failure. Modified-live and killed vaccines protect cattle.
IBR vaccine guidelines
Bovine Respiratory Syncytial Virus (BRSV)
BRSV leads to pneumonia and immune suppression. Vaccination during the dry period is recommended.

Clostridial Diseases
Clostridial bacteria cause fatal diseases like blackleg. Vaccination before calving boosts passive immunity in newborn calves.

When to Vaccinate Pregnant Cows
Timing is critical to ensure optimal protection. Farmers should follow these guidelines:
- Before Breeding: Vaccinate heifers and cows 30-60 days before breeding.
- Mid-Gestation: Booster doses of essential vaccines.
- Pre-Calving (Last Trimester): Vaccination boosts antibodies for colostrum quality.
