Mastitis and some respiratory diseases are among the few examples of disorders for which there are no vaccines, and antibiotics are needed once the infection is established.
Parasite Preparations:
There are many to choose from, however, the best is one that gives broad-spectrum control.
It is better not to use parasite preparations unless they are really necessary. Ivomec is used by many shepherds.
Vaccines and other biologicals.
There are some types of immunizing agents only intended for protection against a disease and have little or no effect in the treatment of the disease.
Vaccination and immunization are two different things, because the administration of the antigen vaccination results in immunization only if the immune system in a sheep is normal and functioning.
Ask your vet to draw up a vaccination schedule for your flock, because vaccination must be done well before the period in which disease occur. Why? Well it usually takes up to 1 month for maximum immunity to develop. However, there are some vaccines that take up to 45 days after the last dose had been administered for maximum protection against a disease.
There are four classes of immunizing agents, and all are commonly called vaccines.
Antisera: These are often called antitoxins or serums, and are from the serum of hyperimmune animals – that is they have received multiple doses of vaccine to confer a high specific antibody level against a particular disease.
An antisera is used for temporary, or passive immunity and its effect lasts between 10 – 20 days. This type of vaccine is used to protect animals for a short time when a disease is present in the herd and also to treat infected animals. It can also be used on lambs.
