Estrus, or heat, is the period in which the doe will stand and allow the buck to breed her. This phase of the reproductive cycle may last between 12 to 36 hours. The period from one heat cycle to the next is referred to as the estrous cycle. In goats, the estrous cycle occurs every 18 to 24 days, or 21 days on average.
There are several strains of the sore mouth virus, somewhere in the area of 10 - 12 is what I have read and have been told by my vet. Each of these strains are different and so the goats can get sore mouth again if it is a different strain. There is a malignant strain of sore mouth, and that is what came in with the animals I brought in. My vet told me that the virus may have mutated because of the sudden severe climate change.
