Vista vaccine bovine

Exceeding the label-recommended time span between the primary and booster vaccination may not make a vaccine ineffective, but it might make the vaccine less effective. Follow label instructions as closely as possible to facilitate development of maximum immunity in response to vaccination.

The best vaccine program will fail if the product is damaged by improper handling. For example, if the label says to store a vaccine at 35 to 45 degrees F, the vaccine should be refrigerated.

Vaccines should not be allowed to freeze, nor should they be stored in direct sunlight. As a rule of thumb, only reconstitute enough vaccine to be used in 30 to 45 minutes, and use a cooler or other climate-controlled storage container to protect reconstituted vaccines from extremes of cold, heat, and sunlight. Keep needles and syringes clean to avoid infections at the site of injection.

Even a trace or film of disinfectant in a syringe or needle can kill the live organisms and make the vaccine worthless. Follow product guidelines for cleaning multi-use vaccine syringe guns, but in general, after use, rinse thoroughly with hot water to clean the injection equipment, and then sterilize it using boiling water.

DO NOT mix different vaccines together in one syringe or combine other injectable drugs into the same syringe with vaccines. Although this method has been advocated as a method of reducing the number of injections, it could inactivate the vaccine because of incompatibilities with the other compounds. Figure 1. Use neck for injections. Do not inject in rump or leg.

The only acceptable site for injection is in the neck, both for intramuscular IM; in the muscle and subcutaneous SQ; under the skin injections see figure Intramuscular injections of some products can cause significant muscle damage, so it is necessary to avoid injecting anything in the top butt or rump of the animal. Injection site reactions can cause damage to valuable beef product, and this muscle damage costs the beef industry millions of dollars a year from lost product and lower calf prices.

All injections should be administered IM or SQ in the neck figure 1. Vaccination alone will not guarantee a healthy herd. Proper nutrition includes energy and protein as well as mineral supplementation. Some calves that have been properly vaccinated with excellent vaccines have still died in the feed yard because their preshipment mineral nutrition was deficient. Minerals such as copper, selenium, and zinc are required in very small amounts in the diet; however, if the forage is deficient in some of these elements and they are not supplemented in a diet or a free-choice mineral mix, the immune system may not function correctly.

To determine the best time to vaccinate animals in your herd, first write down the breeding and calving seasons, and then schedule vaccinations and other management events. For example, blackleg is a rapidly fatal disease of calves.

When protecting cows against reproductive diseases, it is often best to vaccinate at least 6 to 8 weeks prior to the breeding season to allow time for development of a protective immune response. However, if vaccinating cows to increase the amount of antibodies in colostrum against diseases such as calf scours, you may need to vaccinate 1 to 4 months prior to calving.

Vaccine timing varies from product to product, so always follow vaccine label directions with respect to vaccine administration timing to maximize product efficacy. Vaccines are available for many disease conditions. However, many diseases are not a routine threat to most beef herds, and some vaccines are not sufficiently effective to justify their use.

Therefore, only a few vaccines are included in a routine vaccination schedule. The glossary of conditions and terms at the end of this publication lists both routine and not-so-routine infectious diseases and vaccines for them.

Every cattle operation will have unique vaccination requirements based on individual herd goals, so the following guidelines for vaccinating cattle may not be applicable in all situations.

When appropriate, ensure that products are safe for pregnant animals and for calves nursing pregnant cows. Properly store and administer vaccines according to label directions; adhere to designated meat withdrawal times; booster primary vaccinations when recommended; and follow all Beef Quality Assurance BQA guidelines. Replacement heifers, cows, and bulls should generally be vaccinated at least 6 to 8 weeks prior to the breeding season so that immunity is high during the breeding season.

A veterinarian may add or delete vaccinations that are generally recommended for most herds in your location. In addition, a veterinarian can offer objective advice on specific vaccine products. By being involved in the design of the herd-health production calendar, a veterinarian will be better able to help prevent disease and deal with it if it occurs.

Remember to always properly store and administer vaccines according to label directions, adhere to designated meat withdrawal times, and follow all other Beef Quality Assurance BQA guidelines.

An often fatal infectious disease of cattle caused by a microscopic parasite of red blood cells, spread by ticks or horsefly bites or by reusing needles or instruments between animals. A vaccine is available in some states with a conditional USDA license, but unless the risk is high, a routine vaccination for anaplasmosis is not recommended.

A virus that can cause severe, acute respiratory disease, especially in young cattle. A disease caused by bovine viral diarrhea virus BVDV , resulting in numerous problems, such as damage to the digestive and immune systems, pneumonia, abortions, calf deformities, and others. Incomplete vaccination programs, such as those omitting a needed booster vaccination, have led to BVD outbreaks in some herds.

A highly fatal disease of young cattle caused by one type of Clostridium bacteria. See Clostridial disease. An infection resulting in abortion in females and inflammation and damage to the testicles in males, caused by the bacterium Brucella abortus. See Calfhood vaccination. Calfhood vaccination official calfhood vaccination. Vaccination against Brucella abortus for heifers between approximately 4 and 10 months old the exact age for official calfhood vaccination is state specific.

Calfhood vaccination must be administered by a federally accredited veterinarian most large animal veterinarians are federally accredited. Calfhood vaccination against Brucella abortus is not mandatory in most states. Animals given the official calfhood vaccination are marked in the right ear with an official orange ear tag and a special tattoo.
