There is no specific syndrome or infection called "herd disease", so this is a general term meaning "a disease affecting a population of animals". In this context, a herd disease is any disease affecting a herd, which in the United States is generally a collection of ruminants, of which the only domestic species is cattle.
Examples of herd diseases include Moraxella bovis, the bacteria responsible for pink eye or conjunctivitis and primarily affects white-faced cattle like Herefords and baldies; bovine viral diarrhea virus (BVDV), which is perpetuated in the herd through persistently infected (PI) shedders infected in utero; and Mycobacterium avium paratuberculosis, the causative agent of Johne's disease and perpetuated in the herd through chronic shedders infecting calves at birth.

What is herd immunity?
herd immunity is immunizing a sufficient amount of people in a community so that if one person come in with the disease they wont cause an epidemic.
What is herd vaccination?
Herd vaccination refers to when the majority of a population or commumity are vaccinated that it creates immunity against a specific disease that they were vaccinated for. It creates some safety for the nonvaccinated individuals since the majority of the group have developed immunity and are protected from contracting and spreading the disease to others.
Why it is for most of the population to be vaccine?
It is important for most of the population to be vaccinated to achieve herd immunity, which helps protect those who cannot be vaccinated due to medical reasons. This also reduces the spread of infectious diseases in the community, ultimately leading to lower infection rates and better public health outcomes.

What are the economic importance of diseases in livestock management?
Diseases are not an economic importance. They are rather more of a nuisance to livestock management than an importance, since any producer would dream of having disease-free animals all the time without any sort of input to keep them disease free.But I believe you are referring to the economic importance in disease prevention and herd health practices in livestock management. THAT is very important in raising livestock. Having good prevention practices and a good herd/flock health program means more money in the bank when selling excess stock that are healthy. It also means less death losses and production issues when you have good disease prevention practices on your farm. In order to have a good herd/flock health program, you must have a good annual vaccination program for young stock and breeding stock, having and maintaining a quarantine station and program for any new animals that are to be introduced into the herd. The quarantine program ensures that these new animals are tested for diseases that could be detrimental to the rest of the herd, and to keep these animals quarantined until they are deemed safe or not. Finally, culling any and all animals that are sick or tested carriers of a disease is the third and the most important part of a good herd/flock health program. Often it is much harder to maintain 100% prevention rate in your herd or flock if you keep any animals that are sick or are carriers for a certain disease, because they could still pose a risk to the rest of those that are susceptible to that particular illness or disease.
Why are cases of Lyme disease increasing in the U.S.?
The Centers for Disease Control and Prevention (CDC) attributes this increase to the growing size of the deer herd and the geographical spread of infected ticks rather than to improved diagnosis
Can cows recover from foot and mouth disease?
Yes, and most cows will recover from foot and mouth disease (FMD). This disease is mostly economic in its impact - in an endemically infected herd (one that routinely has FMD circulating), generally around 98% of the animals who get infected will recover in a couple of weeks. In a naive herd (one that has not been exposed to FMD), you will see a slightly larger mortality rate, but still have a survival rate over 90%.
