Zhou Fan was surprised to find that next to a big rabbit, there were many rabbits that had just been born, and even the hair had not yet begun to grow, and they looked ugly.

Suddenly, Zhou Fan was stunned, and the next second he searched carefully in the space again.

"Sure enough, these animals are really bred in the system." Zhou Fan muttered to himself.

In addition to the rabbit I saw earlier, there are many other rabbits with a litter of rabbits next to them. Not only that, but some of the sheep and horses in the rest of the herd, and even the mother of the two camels, were pregnant, but they had not yet given birth.

Since Zhou Fan started collecting animals everywhere, he has thought about whether he can let the animals in the system breed their own offspring, after all, if he can, it is much more convenient than collecting animals everywhere by himself, and it doesn't cost money.

But now, I don't know if it's because the system has been upgraded to the third level, and the animals in it have actually begun to breed on their own. And what is even more terrifying is the speed of its reproduction.

Although Zhou Fan worked in a zoo in his previous life, he also knew a lot about the reproductive growth cycle of some animals.

Generally speaking, mature rabbits can give birth to a litter in a month, and the number of rabbits varies from five to twelve each time, and it takes about three months for young rabbits to grow up and be able to breed.

And the growth degree of your own space, one day is equal to three days, that is to say, you can give birth to a litter in ten days, and you can grow to maturity in a month.

As for the sheep and the horse, one takes five months, and the other takes nearly a year, so now they are only pregnant, and there are no sheep and horses yet.

That's it. Even Zhou Fan couldn't help but be taken aback. It's been a month since my system was upgraded to level three, and that's three months in the space, which means that an average female rabbit has about three litters, and one of them has grown up.

How many female rabbits are in this space, Zhou Fan really doesn't know, even if it is half, it is 150. In this way, in this month's time, there are at least nearly 2,000 more rabbits in the space, and those that have not survived have been removed. There must be fifteen hundred, this speed...... Zhou Fan didn't want to say anything more.

But after thinking about it, Zhou Fan was a little depressed, why should there be more than a thousand rabbits in the space now, but now there are only more than 900, and the rest, I'm afraid they have all been eaten by those few goods.

These ten carnivores are already so edible, and it is really unimaginable to expand the number of them.

"It's not worth raising rabbits. Let's change to something else! Zhou Fan smiled bitterly.

There is currently an upper limit on the number of their own space, only 100,000 in total, and at least half of the number must be left for horses. Thinking that there would be at least 50,000 iron horsemen galloping in the future, Zhou Fan was a little excited.

However, this horse cannot be bred for the time being, after all, among the 20,000 soldiers and horses recruited by Zhou Fan, Zhou Fan plans to have at least 5,000 cavalry. At present, there are only about 1,500 horses in this space, and I am afraid that in a short period of time, I will still have to trade with Nagongsun Chan to form a cavalry, but I will wait until the future. Zhou Fan is afraid that he can get rich just by selling horses.

As for the remaining half, leave a little space for those special animals, such as white tigers, silver snakes, tiger mounts, etc., and the rest can be used to raise meat and poultry and feed those tiger mounts.

At this time, the problem also came, the rabbit is so small, and the fat whole body is only seven or eight catties of meat, and it also has to occupy a space, which is not cost-effective at all, and it may not be able to afford to raise the tiger cavalry, and the cost performance is too low.

And Zhou Fan also has an idea in his heart at the moment, what to raise.

That is pig raising, although Zhou Fan has also collected pigs in the space before, but he has never thought of raising more. In this day and age, pork is not eaten by most families, wealthy merchants and the like, and only some commoners eat it. At that time, Zhou Fan was in Luoyang, all of them were rich people, so naturally they would not have nothing to do to raise some pigs in the space.

Generally speaking, sows can enter the herd and breed from the age of 8 months, and their average pregnancy time is 114 days, and a litter can give birth to 12 to 20 sows.

And a pig out of the slaughter is about five or six months of appearance, at least more than 200 pounds of weight, more than 200 pounds of a pig, absolutely enough for ten tigers to eat for a day, anyway, are all meat, I believe that those tigers are definitely not picky eaters, compared with other animals, this cost performance is definitely the highest existence.

Immediately, Zhou Fan said what he thought in his heart, and told Xun Yu and them, anyway, they all know about this system, there is no need to hide it, but more people can help him staff if he says it.

Suddenly, the three of them were a little speechless, and they couldn't help but sigh at each other, what is this called, you Zhou Fan is also a dignified champion, and you are so proficient in raising pigs and sheep, it is really speechless.

"Ahem!" Cheng Yu couldn't help coughing twice and said, "Yu doesn't know much about this matter, but if it's really as the lord said, the lord might as well form a tiger cavalry of three hundred people first." ”

"Three hundred!" Zhou Fan thought about it for a while, this number is indeed a more appropriate number, the space is so large, it is more than enough to raise three hundred tigers.

"Okay, according to what Zhongde said, three hundred tiger cavalry, when the time comes, it will be controlled by evil!" Zhou Fan immediately made a decision. Three hundred tiger cavalry, that is definitely an existence against the sky.

"If you can, the lord can also distribute the surplus pigs, cattle and sheep and other poultry to the local people to raise, so that you can not help but give the people of Hanzhong an extra income, and it can also help the lord relieve the pressure." Chen Lin on the side spoke.

Zhou Fan couldn't help but nodded, it is true, after all, the space is limited, and it cannot be relied on alone, although the growth rate of poultry raised outside is not as fast as the space, but there is no limit to the quantity.

Just like Chen Lin said, lend some surplus poultry to the people of Hanzhong, let them help them raise it, and then take it back proportionally, which can not only give the people one more way to make money, but also make Zhou Fan's space run better, killing two birds with one stone. However, at present, these are still empty talk, how to allocate the number of space, Zhou Fan is not really engaged in breeding, and he has no experience, and only practice will be the main thing when the time comes.

"Just according to Kong Zhang's words." Zhou Fan said with a smile.

"Lord, Lord and Duke Lu are ready to leave!" At this moment, Zhou Feng walked in and said. (To be continued......)
