Much of the country will be vaccinated against foot and mouth disease and brucellosis. The latter generates losses in livestock production and also has an impact on public health.
In order to strengthen the health of the national rodeo, the next The vaccination campaign against foot-and-mouth disease and brucella will begin on Tuesday 11 October for the categories of minor cattle of the central-northern provinces of the country. This implies that, with the exception of cows and bulls, all categories will be vaccinated of rodei.
The foot-and-mouth disease control campaign is the second of the bovine year. And within the framework of it, the vaccine against bovine brucellosis in all calves between three and eight months old.
It’s a strategic immunization. Brucellosis is an infectious disease caused by a bacterium, which produces large economic losses and generates a strong impact on public health as a zoonosis. The good news is that it can be controlled through a proper vaccination schedule and farm supervision.
More precisely, the National Plan for the Control and Eradication of Bovine Brucellosis defines strategies and actions for those farms where reproductive activities take place, and its pillars are vaccination and serological diagnosis of animals. It includes, as mentioned, the compulsory antibrucella vaccination of all calves from three to eight months of age, with the Brucella abortus strain 19 vaccine, and also the Obligatory Determination of the Health Status (DOES).
The disease causes miscarriages and reproductive problems in female cows; consequently, it has a negative impact on animal production. “The weaning rate in Argentina was 63.1%, well below the United States, where it reaches 89%, or New Zealand, where it reaches 80%. This shows that there are great possibilities to improve the productivity of national livestock and the health issue is fundamentalsince in rodeos there are various viral or bacterial diseases that can cause abortions ”, remarked Melina Brosso, coordinator of Tecnovax Technical Assistance, a leading company in the development of vaccines and biological products for animal health.
It is important to note that there are measures to prevent most infectious diseases in cattle and that many reproductive losses can be avoided simply by following the vaccination plan.
Pre-service recommendations
Precisely as part of the vaccination plan of a rodeo, before entering the service phase, the application of Providean Repro 12, a polyvalent vaccine for the prevention of abortions and reproductive failures, is recommended in the 30 days prior to the start, always and when the animal has a previous vaccination history. If the breeding has a history of abortion problems in the last third of pregnancy, a booster should be applied to the females at the time of touching.
“If the animal is vaccinated for the first time, it is recommended to apply a dose of Providean Repro 12 60 days before the service and a booster 30 days after; keeping the practice of an additional application at the moment of touch, ”said Brosso. And he added that in the case of males “they must perform two scrapings before entering service, pending a negative result for campylobacteriosis and trichomoniasis. If the venereal test is positive, the animal must be discarded ”. Subsequently it is necessary to carry out the vaccination before the start of the service, according to the veterinary indications.
prevention of abortion
Vaccination programs and biosecurity measures are essential to prevent abortions in female cows. They manage to significantly reduce the incidence. However, due to the conditions of intensive production, it is not possible to completely eliminate abortions. “The correct choice of vaccine that contains the antigens for the abortion-producing agents and with the potency per dose to generate a good immune response is essential,” explained biotech company Tecnovax.
