Presumably you think the technology in a cloning factory is more expensive than bridge making equipment, but maybe you're not taking into consideration the various codes and legal requirements that are necessary to build a bridge.
The point should not to have more cattle, but to produce food in a more sustainable way.
In my opinion they should aim to produce meat in vitro.
It depends on what is your time horizont, it depends on your values, it depends on your actual problem right now.
What I said, is that, in my humble opinion, from my perspective, is more valuable to work on a way to make meat sustainable and affordable for all than to work on cloning.
To the extent that it's not it might be improved by genetic engineering, and I doubt that producing the same meat in vitro will be a net improvement in sustainability for a long time. Now you've replaced a natural organism that needs some fodder and produces CO^2 with an entire factory, employees to manage it etc.
Why do you think that's more sustainable? One of those processes relies on non-technology that existed before there were even humans around, and the other needs high-tech that we don't even have yet.
We can solve this in two way, or we stop eating meat or we start growing meat in a more sustainable way.
The problem is not something to look in the future, but it is something really tangible, to have an idea of the order of magnitude I will post here a strip for xkcd[1]
The "efficiency" of a cow is really low, it is estimate[2] that half of the energy you put into a cow is necessary just to keep it alive.

Like, "animal husbandry can manage genetic variation, but cloning can't" ? Doesn't add up. In both cases you can have humans in the loop to make sure sufficiently diverse samples are preserved and used in populations.
All livestock populations should be genetically monitored, anyway.
