Simply, more exposure to diseases from animals means better immunity in the long run.
As Europeans were exposed to these diseases, they will likely have issues at first. But, their bodies will develop immunity towards these diseases to the point where many bacteria cannot even affect them at all.
Let's look at a civilization that mostly did not have livestock, Native Americans. They were pretty clean and healthy. That is because there were no diseases to kill them until the Europeans came to North America. For example, the flu virus was something a European could handle with a little bit of rest. On the other hand, the flu virus wiped out most of the Native American population since they never had exposure to it.
the hijra, Muhammad's journey from Mecca to Medina in the year 622. It is after this event that jihad begins to become an issue. The new Muslim emigrants to Medina needed a way to maintain their livelihood. They pursued the most expedient course, and began raiding the caravans of the Meccans.
In the raids the Muslims were taking the offensive. Muhammad cannot have failed to realize that, even if the raids were only slightly successful, the Meccans were bound to attempt reprisals. In these little raids, then, he was deliberately challenging and provoking the Meccans. In our peace-conscious age it is difficult to understand how a religious leader could thus engage in offensive war and become almost an aggressor.
