Best Breeding tips and what to breed?
So I got the game today and have basically played all day (tutorials, and starting career mode)

But now I think I can leap into Franchise mode, and once I get my feet on the ground, I would like to start breeding.

I am just wondering any god guides, tips or videos that explain everything to do with it?

And how you would keep track of inbreeding...is it a simple case of when I start breeding programmes, I would severe each male off from the main enclosure and only put in a female I want to make them mate with?

Thanks OG

Breeding animals in the game is pretty easy. Unlike real life where some animal species are difficult to breed in captivity, animals in Planet Zoo will breed with very few problems (provided you have meet their needs and they are fertile)

The best guide is to use is the in game Zoopedia. It gives all the information you need to meet your animal’s needs. As far as breeding you need to look a few key points

(For this I'll use the Bactrian Camel as an example)

First is Group size: Some animals are solitary by nature while others live in packs/herds etc. For the Camel the group size is 2-11 (1 male and up to 10 females)

So, you could place 1 male (who will be the Alpha) and up to 10 females, who will all breed with the Alpha male.

But it says 2 males how does that work with females? In short, it doesn't. This leads to my second point...

Dominance: Some animal species have a dominance system, either male or female (the same as in real life, they in may fight another of the same gender, of breeding age, for rights to mate)

Back to the camel example: 2 male camels could live together as "bachelors" only. If they were with females they would fight (a lot) for breeding rights and alpha status, leading to injuries and possible death in your zoo.

So, if you are breeding check who is dominant and only have 1 adult of the dominate gender (offspring do not count as they can't breed) If there is no dominance, just have 1 male and 1 female for ease.

and final point to notice is Mating System:

Some animals mate for life and have a Monogamous breeding system (1 male/1 female, the same partner each time), others have a Polygynous system (1 male, many females) or Promiscuous: random parings, not much mating structure (To make it easy I would keep it the same structure as Polygynous, unless dominate female)

Which leads back to your question of inbreeding and how to stop it. Short answer, like humans, you put animals on contraceptives to stop unwanted pregnancies (right hand side of option in the Animal tab of the Zoo menu). Long answer, it involves a degree of micro management.

Every few (in game years or so) you'll probably need to check your population of animals, how many juveniles, how many adults, do they fight for dominance, do I have adults who are too old to breed (elderly) do I have the risk of brother and sister mating as the only other breeding male/female is their parent.

A tip is, to put all new born on contraceptives, this is handy when you have animals that have a lot of young and you have a large zoo and a lot of management between enclosures. This gives you time to sort out other matters, without risking missing the notification that the young are now grown and of breeding age

Contraceptives in the game are 100% successful, and although they will mate with siblings/parents etc. you won't get any offspring. In the mean time you need to ask what do I do with them

Are the parents too old to breed, then perhaps you will need to release the parents to the wild and breed the young adult with a new male/female. Or you could keep the parents for future breeding and put the young adult children into the trade center for future breeding projects

(Animals do not age in the Trade Centre) or 3 just release them to the wild, or sell them on the market board for CC

In the end it’s all up to you. Sorry this post is so long, but my advice is to is don’t stress and start small.

Tldr: Have animals that have simple mating structures. It’s all trial and error. If you get notifications of infighting or risk of inbreeding, you’ll need to step in and manage it.

Look at the zoopedia for suggested groupings .. for example many are happy with one male and one or more females. As soon as you can turn on contraceptives for any animal you do not want breeding yet. This can be done at birth via the zoo animal list or via their detail page when they mature. If you start running out of space or there are too many animals in the habitat then either build a second habitat to house the non breeding adults ( babies don't take up space ) or store/sell/trade/release as needed.

Start with animals that have a short breeding cycle which will result in a speedier turn around. This will help building up a gene pool to select from for the next generation. I find the best way to handle each generation is to sell off almost all of your males and buy a new one to breed with the females you want to breed next.

Rinse and repeat as needed.

To help build up some cash flow, use exhibits to breed and sell the animals.

Thats the basics, I am sure someone will offer more specific suggestions.

Thanks, this is exactly what I wanted. :)
I quite liked Bison, as what I was doing (just now) was releasing the young males, until my original male was too old (or getting). Then I boxed up "good" breeding males (which again I need to look into the gene stuff too) and waited until they rotate.

I guess I see how it goes, when I start franchise mode tomorrow. Maybe I can help on how many are in the system eventually!

No worries. Happy to help (and Happy New Year :D). I wish you the best, if you have any issues or questions don't hesitate to ask. We are a friendly Planet Zoo community.

I have a 25 species zoo running at the moment so I regularly trade out several of each, mainly African, but I do have south american and Australian zoos running as well.

Some additional tips:
Keep animals as happy as possible with highest welfare. (Sad animals don't breed as much).
Fully research your animals. (because the research can give you fertility bonuses).
Make sure your animals have enough space for them and future kids (for animals that can have multiple kids at a time, some have found that they'll have more if there's space and fewer if there's not).

When you get to the point of thinking about stats, focus on the first two first (size and longevity). These two stats come from the parents directly and are easiest to control, while the final two (fertility and immunity) are generated a bit more randomly and vary quite a bit even within the same litter of kids.

And you! Hoping for a better 2021 quite honestly. (shaping up to be, although I am "going back to work" on a project when I retired last January :\ )

And you do seem to be, which is good, because I become very active if the community is good with the game I have found. I either seek it out subconsciously or I am just lucky with communities. I run a group in Two Point Hospital and I curate lists for CNE's Idle Champions. So hopefully, maybe I make another group with this game or just a thread, if needed, to co-ordinate breeding or something. However, still learning so it might not need that level of organisation.

Thanks, I need to start writing these down.

Major plot points seem to be:
Find an animal (check zoopedia for specifics)
Contraceptives - use on all children (until your ready to breed them)
Inbreeding is a thing - rotate as necessary.
Short breeding cycle is better to get your feet
Start small then expand
Happy Animals = more offspring
More space for litter animals = more offspring
Focus on size and longevity

Probably someone has done it, but I might make profiles on animals when we get into it and see if we can manipulate all the stats.

at the current time I have only vanilla+deluxe. But I will probably pick up all DLC either in a couple of days or next sale.

The reason is I am an "onion style player"
So I peel back layer by layer. If I add things too quickly, I get overwhelmed haha.

ps. I can't NOT get penguins though. As a kid, I still remember going into London Zoo and feeding them. Then, not sure how, I fell down, and they all (the penguins) all huddled around me. The zookeeper said that was a tactic in the wild to keep the young safe.

you may only see animals you are allowed to so that trading list should grow reflecting any changes you make to your game content.

A few further questions:

1. Exhibition Animals can they not be released into the wild? & I just sell them on the market but for cash only not for the leaf currency?

2. So I am breeding Indian Peafowls, which seemed to be the quickest. I got 4 golden males (very cheaply) and 3 female (one being albino - so got an achievement without realising it haha). And it is going well.
My questions are:
a) do I "release to wild" the offspring to gain the leafs or
b) can I sell them for leafs and not money?
I appear to only see quick trade all the time.
c) most of the offspring are - albino + 1150+ Golds, so don't want to release if I don't have to and sell them on the market again.

3. Can I set the value of leafs, when I can trade in them?

4. Generally, is selling your own on the market how you get the leaf currency up?


note: leaf currency is conservation points or whatever they called.

Many thanks

Hello again :) Glad to hear things are going well

1. So if you bought your animals for cash (not Conservation Credits) you can only sell them again for cash. Animals bought for CC can be sold/released for CC. You also cannot release them to the wild if you bought them for cash. Their offspring are different and can be sold for CC or released to the wild.

2. You can sell them on the market for CC or release to wild (see point 1) Peafowls are very common, easy to breed and have a lot of offspring so you might have trouble selling them again on the market for much of a profit. Try the market but if no sale then I would just release to the wild for a small but easily attainable amount of CC

3. Yes, anywhere from 1 to 10,000 CC (*note nothing is worth 10,000 CC, even an albino with perfect stats, it's usually a greedy player trying to rip someone off)

4. Not really. The value is determined by the players not the A.I. In franchise you are buying and selling animals to players (excluding Frontier). Prices and demand often fluctuate wildly, especially with Albino animals. You need to shop around, if prices are too expensive, or that animal species is not being sold, then come back another time. The community is still active and for the most part its common to see new animals appear after a few minutes when the selection was previously blank.

Keep an eye out for those Frontier animals that appear from time to time. You might get lucky and find a really cheap animal with pretty good stats (grab that bargain :p)

Try not to get to hung up on those perfect stats and gold stars early (these animals usually cost more to buy). Animals with poorer genetic stats breed just as well, and save you that valuable cash/CC in early game :D

Thanks for all the tips. I have amounted over 5000 (To buy golden lions (they seem to be really short supply for money)) Which I got a good pair for only 3500 all. Hopefully they breed a lot haha.

I still don't quite get fertility/immunity as I try to not get them inbred (sometimes they push it). But with the Indians Peafowls I have now a nice circuit of 4 habitats. With 1 male to 4 females in. Then all I do is watch the alert when they say "matured", look at them if good and female I move them over to the one to the left. If bad I release to the wild. If they are semi good I sell them in the market. If the male's are better than the next over habitat, they replace that stud.

Then I sell leftovers. Got to the point where I achieve around 20-25 Golden 750-766 (seems to be the cap?) 4x100 every hour.
So yeah been raking it in. On the market I set it simply as 100 or 200. If they don't go, I go down by 20. On their third I half it.
But as so many come in and go, it makes little difference to me.

I did see someone try and resell a 4x100 for 5,000cc though, like you said. Not sure anything is worth that, especially not peafowls...they breed every 2 years it seems and have 2-4 babies. So that's why I do 100 for every 100 they have in their stat. As, you can breed up to like 16-22 babies per pair.

So now, onto the harder stuff. I have played around with wolves. Accidently bought a brother and sister at first!! But soon have figured it out. Just a slwer than Peafowls. I have no clue about the market there. I seem to be selling them at 500cc each pretty well and some are not even gold standard.

I've been experimenting with switching the 'alphas' around in pack groups, in order to speed up the baby-making process. It seems most successful with the African Wild Dogs. So you have a species where only the alpha male and alpha female of the group will mate. Let them mate, then soon after the baby is born (or even while the mom is still pregnant), just move the alpha couple to the trade building for a little while. Different dogs (or animals) in the pack will step up to alpha rank, and in some cases, mate quickly. You can move the old alphas back from the trade building to the habitat (especially mom, so she can be with her young offspring) but they don't get alpha status back automatically.
