It means-- too many things are being expected from one source or more literally---
There is no such thing as an egg-laying pig that grows wool and gives milk (that anyone would want to drink).
("es gibt keine" translates as "there is no...")
If you want eggs-- go find a chicken who is good at this sort of thing.
If you want clothing-- look for sheep with a good coat of wool.
If you want milk-- it's better to look for a cow.
And make sure each animal is willing to share what it has with you!
Even with this, some people don't eat pork, so the pig could easily be rendered totally useless! [:P]
Likewise-- too many things running on one machine could render the machine totally useless.
