Introduction:

PPPPPIn the realm of livestock farming, maintaining the health and productivity of cattle is paramount. Vaccination serves as a cornerstone in disease prevention, safeguarding these animals from various infectious agents. However, navigating the intricacies of vaccination schedules can be daunting for farmers. This comprehensive guide aims to demystify the process, providing a detailed overview of recommended vaccination schedules for cattle. By understanding the timing and frequency of vaccinations, farmers can effectively protect their herds and ensure optimal health outcomes.

Sr. No	Name of Disease	Age at first dose	Booster dose	Subsequent dose
1	Foot and Mouth Disease (FMD)	4 months and above	1 month after first dose	Six monthly
2	Haemorrhagic Septicaemia (HS)	6 months and above	–	Annually in endemic areas
3	Black Quarter (BQ)	6 months and above	–	Annually in endemic areas
4	Brucellosis	4-8 months of age (Only female calves)	–	Once in a lifetime
5	Theileriosis	3 months of age and above	–	Once in a lifetime. Only required for crossbred and exotic cattle
6	Anthrax	4 months and above	–	Annually in endemic areas
7	IBR	3 months and above	1 month after first dose	Six monthly (vaccine presently not produced in India)
8	Rabies (Post-bite therapy only)	Immediately after suspected bite.	4th day	7,14,28 and 90 (optional) days after first dose

Foot and Mouth Disease (FMD):

Foot and Mouth Disease (FMD) stands as one of the most economically significant diseases affecting cattle  worldwide. Vaccination against FMD typically begins at 4 months of age or older. The initial dose is administered, followed by a booster dose one month later. Subsequently, vaccinations are repeated at six-month intervals to maintain immunity. This rigorous schedule is necessary due to the highly contagious nature of FMD, which can spread rapidly within herds and cause severe economic losses.

Haemorrhagic Septicaemia (HS):

Haemorrhagic Septicaemia (HS) poses a significant threat to cattle , particularly in endemic regions. Vaccination against HS usually commences at 6 months of age or older. Unlike some other diseases, HS vaccinations do not typically require booster doses. However, in areas where HS is prevalent, annual vaccinations are recommended to ensure continued protection. This approach helps mitigate the risk of outbreaks and minimizes the spread of the disease within susceptible populations.

Black Quarter (BQ):

Black Quarter (BQ), caused by the bacterium Clostridium chauvoei, primarily affects young cattle. Vaccination against BQ typically begins at 6 months of age or older, similar to HS. As with HS, booster doses are not usually necessary for BQ vaccinations. However, annual vaccinations are recommended in areas where the disease is endemic. By adhering to this schedule, farmers can effectively reduce the incidence of BQ and protect their livestock from this potentially fatal disease.

Brucellosis:

Brucellosis, caused by the bacterium Brucella abortus, poses a significant concern for cattle producers, particularly in terms of reproductive health. Vaccination against Brucellosis is typically targeted towards female calves aged 4-8 months. Unlike some other diseases, Brucellosis vaccinations are administered as a single dose, with no subsequent booster doses required. This one-time vaccination provides lifelong immunity against Brucellosis, thereby reducing the risk of transmission within herds.

Theileriosis:

Theileriosis, caused by various species of the protozoan parasite Theileria, primarily affects cattle in tropical and subtropical regions. Vaccination against Theileriosis is typically initiated at 3 months of age or older. Similar to Brucellosis, Theileriosis vaccinations are administered as a single dose, with no subsequent booster doses required. However, it’s important to note that Theileriosis vaccinations are primarily recommended for crossbred and exotic cattle, as indigenous breeds may exhibit natural resistance to the disease.

Anthrax:

Anthrax, caused by the bacterium Bacillus anthracis, poses a significant threat to livestock, wildlife, and humans. Vaccination against Anthrax typically commences at 4 months of age or older. Similar to FMD, annual vaccinations are recommended in areas where Anthrax is endemic. This proactive approach helps prevent outbreaks and minimize the risk of transmission to other animals and humans.

IBR (Infectious Bovine Rhinotracheitis):

Infectious Bovine Rhinotracheitis (IBR), caused by the bovine herpesvirus 1 (BoHV-1), is a highly contagious respiratory disease affecting cattle worldwide. Vaccination against IBR usually begins at 3 months of age or older. The initial dose is administered, followed by a booster dose one month later. Subsequently, vaccinations are repeated at six-month intervals. However, it’s important to note that the IBR vaccine is not presently produced in India, posing a challenge for farmers in the region.

Rabies (Post-bite Therapy Only):

Rabies is a zoonotic disease that poses a significant threat to both animals and humans. Vaccination against Rabies is crucial for preventing transmission and protecting livestock from this deadly virus. In cases of suspected Rabies exposure, post-bite therapy should be initiated immediately. This involves administering the initial dose of the Rabies vaccine, followed by booster doses on the 4th day, and subsequently on days 7, 14, 28, and 90 (optional) after the first dose.

Conclusion:

Vaccination serves as a cornerstone in disease prevention and control within cattle populations. By adhering to recommended vaccination schedules, farmers can effectively protect their herds from a range of infectious diseases, minimizing the risk of outbreaks and safeguarding both animal health and economic viability. However, it’s essential to work closely with veterinarians to develop tailored vaccination programs that address the specific needs and risks of individual herds. With proactive vaccination strategies in place, farmers can promote the health, welfare, and productivity of their cattle and buffaloes for generations to come.

Points to be noted during vaccination

• Animals should be in good health at the time of vaccination.

• The cold chain of the vaccines wherever prescribed should be maintained till the time of administration to the animal.

• The manufacturers’ instruction on the route and dosage should be strictly followed.

• A minimum vaccination coverage of 80% of population is required for proper control of the disease.

• It is beneficial to deworm the animals 2-3 weeks before vaccination is carried out for better immune response.

• Vaccination should be carried out at least a month prior to the likely occurrence of the disease.

• Vaccination of animals in advanced pregnancy may be avoided even though in most cases nothing untoward may happen.
