Could anyone help me identify a couple of sci-fi novels I've forgotten the titles of?

The first one is a short story, written somewhere between the 50s and 70s, about a moon base in which a couple of engineers built a series of machines that can produce milk and meat from raw ingredients and they call it an artificial cow.

The second one is a novel series. Protagonist is one of a group of people digitally replicated into dozens of sleeper exploration ships. After the ship arrives a group of aliens build several towers full of technological gifts including an energy-field spacesuit and a small golden FTL vessel. Shortly afterward it turns out a hostile species is following the gift-givers and destroying any species that receives the gifts. Protagonist escapes in the FTL ship and returns to earth to find that he is the only copy of his original that didn't go insane and that the aliens have followed him back to the solar system. He escapes with a companion as the solar system is destroyed and they embark on a quest to find out what the enemy ships are and why they do what they do.
