No-just no.
1. Camels need 1,000 to survive for 200 years.
2. Camels could break out, rusted enclosures, zoo personnel let them out, they find they can walk over the small railings and go to the nearest exist. Camels can go up to 7 weeks with out water and two months without food.
3. How would Cows survive the radiation? Camels puke it out which is more effective in taking it out then digesting it.
4. How did Cows survive? Cows need more food and water then a Camel and are tamed.
5. Fatt reserves. How did Cows survive if they didn't? And where does it say Nuclear winter happened first? It's what they though in the the 50's that desert would come out. Nuclear winter is impossible unless everysingle country has millions of them and they explode simultaneously and even then it's only for weeks.
6. Same goes for Cows.
Logic'd
1. 1000 what?
2. Break out? I doubt the gates will rust timely enough for them to break them, and why would the zoo personnel let them out? Wouldn't they worry more about their families and friends making it into a bomb shelter?
3. Camels puke out radiation? And like I said, I'm sure one hell of a lot of cows died because of the nuclea winter, but because they have such vast populace in north america they manged to reproduce thanks to their numbers.

5. The Reservationists journal mentions the nuclear winter happening a couple of days or maybe a month after the bombs fell.
6. Yeah, but cows have greater numbers.
For crying out loud of course cows had the same problems as camels would have, the difference between them is that cows already had such great numbers that despite so many dying their race was able to prevail.
A zoo of a dozen to three dozen camels cannot survive that.
Cause with each camels death their numbers are reduced, and the less camels, the less offspring, the less offspring the less the the survival probability for their race on north america is.
Cows don't have that problem, if an entire herd is killed by a family of Deathclaws it doesn't matter, cause a mile or two away from there is another herd, and a mile or two away from there another, and then another and another.
These camels would have one herd, no more.
What happens with each death?
Their numbers are dropped.
What happens if a pack of deathclaws find them?
What happens if raiders find them?
What happens if Yao Guais find them?
What happens if Gecko's find them?
What happens when one of them catches a disease? Will it spread onto the others? Will they die?
Each death, whether by disease, poisoning, attack from animals, mutants, humans or some other accident will do a serious blow to not only the herd, but their entire race on the north american continent.
It's not logical at all for them to be able to survive for 200 years in post-apocalyptic USAnia
Cause let's say the first herd survives, the "entire" herd, then after 3 generations a pack of deathclaws find them?
A third to 50% of the pack would be slaughtered.
What happens if a gang of raiders find them?
They'd shoot them dead for their meat.
Even if the first herd managed to survive it's too improbable for them to survive the harsh wasteland for 204+ years.
So tell me, how are they suppose to survive all of this?
"But cows did."
Cows have far greater numbers, they likely have tens of thousands of herds all over north america, some which are protected by brahmin barons and other farms.
So really, you find it plausible that a herd of camels can survive through all of this?
Cats didn't.
Horses didn't.
And their numbers were vast compared to these camels.
[edit]
Camels are very amazing, I'll say that, but they aren't some kinda super animal that can hear or see or sniff a mutant or raider or deathclaw or gecko from a mile away.
They aren't faster than a gecko or deathclaw or Yao Guai, they aren't (as far as I know) immune to diseases and poisons.
So yes, they have amazing survivability but that doesn't mean they are above anything else, let alone cats and horses which did go extinct.
