This is another tough one. Usually "livestock" or "farm animals" or just "animals" would be OK, "livestock" being more professional.

From your other questions on this subject, I would agree with the other postings for "livestock". One problem with "livestock" is that it is a mass noun and cannot be used for just one animal. If your "Haustier" is singular then just use "animal" or "cow" or whatever it is.

For future reference though, Duden defines "Nutztier" as "Tier das vom Menschen wirtschaftlich genutzt wird", which is very similar to the NODE "livestock" definition of "farm animals regarded as an asset" with exception of the important English word "farm". The sheepdog on a sheep ranch would normally not be considered "livestock" but the sheep would. Both the sheep and the dog are probably "Nutztiere".

Under the oversimplified Duden definition, might also fall guard dogs for commercial property, fish in a fish farm, a Seeing-Eye (guide) dog, and circus animals, none of which would probably be called "livestock" (except perhaps the circus animals) in English.

"Livestock" to me means to me that we only keep the animals to later sell them or their offspring. The "offspring" includes eggs, calves, piglets, etc.

Duden defines "Haustier" as "nicht frei lebendes, an den Menschen gewöhntes Tier, das oft aus wirtschaftlichen Gründen gehalten wird". This is a "domestic animal" according to NODE, "an animal which is tame and kept by humans".

A pure "pet" is a "domestic animal" and a "Haustier", and maybe even a "farm animal" but not "livestock" or a "Nutztier".
