"Ancestral God, do you see if the big bull I caught is strong?" Far away, Dashan shouted at the top of his throat, with excitement on his face.

Zhang Jun chuckled and nodded, and beckoned to Dashan: "It's hard work, this guy weighs several times heavier than you, and you guys don't have a lot of strength, it's already very good to be able to subdue it." ”

The mountain took more than half of the strong flying dragon of the branch, and then the bison was lassoed with a rope, and then wasted the strength of the two tigers, and when the crazy bison struggled to exhaustion, it slowly trapped its body with a dozen ropes, and dragged it back, along the way the big bull also struggled several times, almost escaped, more than a dozen strong men were tired and sweaty, and there were beads of sweat on the fluff on their bodies.

"As long as we can complete the task of raising cattle from the ancestral gods, it is nothing if we work hard." The mountain grinned and approached, but the fangs were so cute at this time.

Zhang Jun and several ancestors walked a few steps and greeted them, and then Heipi suddenly stood up and said to Dashan: "Let the ancestor help you, this beast is too fierce, only the ancestor can subdue it." ”

Dashan smiled and said: "With the divine power of the ancestor, we will be much easier, then we will watch the performance of the ancestor." ”

Dashan waved his hand lightly, and the dozen or so leaping dragons beside him immediately retreated to the sides, putting down the thick rope in their hands, and the bull's body suddenly loosened.

The bull is nearly two meters tall, about three meters long, and weighs more than one and a half tons, making it the strongest of the bison.

Hei Pi didn't move, watched the big bull run a few steps, and then suddenly took a step, directly behind the bull's buttocks, and then the two forelimbs suddenly swung out, one like a vice, clamped the left and right sides of the bull's body, the bull roared a few times, and kicked under his feet, but no matter what, he couldn't break free from Hei Pi's claws.

"Let the ancestor give you a ride, and enjoy it with those cows." The black skin, who has always been serious, couldn't help but joke at this time, and laughed at the big bull.

Then I saw that Heipi directly grabbed the big bull, turned around and walked a few steps, and reached the entrance of the cowshed, where there was a thick wooden door, and Heipi's stature was too tall to pass through the narrow wooden door, so he had to put the big bull in the entrance.

Dashan and a dozen young men, as well as a few flying dragons with dust inside, immediately surrounded him, grabbed the rope that held the big bull, closed the wooden door, and forcibly pulled the big bull through a corridor several meters long, into a section of the breeding area.

There were five or six cows, looking at the big bull who had just entered, because they were all in heat at this time, and their desire for the bull was strong, and not only did not reject the new joiner, but took the initiative to give it a place.

After the big bull entered, it immediately ran a few laps inside, it was full of wild surnames, and was locked in the bullpen, very reluctantly, but after running for more than a dozen laps, it gradually felt tired, and then it saw that there were a few cows in it, and there were no other bulls to compete, and it slowly relaxed, and it felt that those dinosaurs didn't look like they were going to hurt themselves, so they didn't run around.

In the next period of time, the big bull will enjoy the entanglement with a few cows, and soon those cows will be pregnant, and the gestation period of the cow is also very long, similar to that of humans, so a cow can only give birth to a maximum of one calf a year, and the calf can only mature in three years.

The roof of the breeding area is sloping top, both sides are sloping, the middle is built with logs, the cattle pen is made of large stones, in case the bison collide and cause the cattle shed to collapse, there are also troughs, workers and other facilities in the breeding area, although it can not be compared with modern cattle farms, but also basically meet the needs of breeding.

Zhang Jun took several ancestors to inspect the breeding area for more than ten minutes, listened to the introduction of the specific work of the ash and the mountain, and put forward some suggestions for improvement, and the mountain and the ash soil were kept in mind.

"Let's have fun breeding these bison, let's go over there." Then Zhang Jun said and took the ancestors to another area to inspect.

Everywhere he went, Zhang Jun greeted the dinosaur workers and had cordial talks with them, which was quite similar to the modern state leaders inspecting the living and breeding areas of rural residents, and Zhang Jun finally experienced a kind of great leadership, at least he is now at the level of the head of state.

After listening to the introductions of workers of different types of work in various positions, Zhang Jun learned about some difficulties in the construction process, remembered them in his heart, and prepared for future improvements.

The construction plan of the bullpen is almost all conceived by several ancestors, only they have this advanced wisdom, the gray soil and the mountains and Nanxiong, they have just been brought to civilization from barbarism, just like a primitive tribe people have entered the big city, to accept the fresh architectural concept, it still takes a long process, and their brains are not as smart as the ancestors, and the digestion ability is also poor, and they need the personal guidance of several ancestors to complete the specific work.

At this time, half a year has passed, under the careful guidance of several ancestors, the dragon group has gradually matured, and a group of labor experts have emerged among them, proficient in the work at hand, and when the new cattle farm is built, Zhang Jun will not be so tired.

Time flies, five years have passed in a flash, five years later, the construction of this cattle farm has long been over, has been renovated several times, gradually improved, from a distance, neat cattle shed is located in the valley, front and back have thick fence protection, ordinary beasts can not approach at all.

After some twists and turns, the construction of the cattle farm gradually stabilized, and the number of bison in the cattle farm gradually reached about 2,000, which can basically meet the food needs of the dragon herd.

Over the next few decades, Zhang Jun plans to expand the cattle farm to several locations and develop new farms at the rate of population growth. In order to improve the dietary structure of the dragon herd, Zhang Jun plans to build new breeding bases such as deer farms, pig farms, chicken farms, and sheep farms to ensure the different nutritional needs of the dragon herd.

And Zhang Jun is still trying to let the dragons eat wild fruits, such as apples, plums and other vegetarian food, although the stomach of dinosaurs is not suitable for vegetarian food, but Zhang Jun knows that the lifespan of vegetarian animals is usually higher than that of carnivores, and there are many benefits of vegetarianism, which has long been verified in the period of medical development.

Now the wild fruits eaten by dinosaurs cannot be effectively digested, but as long as they slowly change their eating habits, the dinosaurs' stomachs will gradually produce enzymes that can digest starch and other vegetarian ingredients, so that the dinosaurs' diet will develop in a better direction and become omnivores, which is also very helpful to the evolution of the brain.

In addition, Zhang Jun considered that the food demand of large Allosaurus was large, and his unique population also needed to develop, although he did not expect the number of Allosaurus to be comparable to that of Flying Dragon and Flying Dragon, but at least it was many times larger than the current small scale of more than 20 dragons.

The only way for Allosaurus to reproduce is that there must be large animals of comparable size in their food structure, and the number of these large animals must reach a certain size to ensure that Allosaurus can develop to a greater extent.

Zhang Jun thought of the ground sloths and giant rats he had encountered, as well as elephants, these animals were the first animals he thought of, and they could be the best choice for Allosaurus food, as long as their numbers reached a certain size, it was enough for the Allosaurus population to continue to expand.

So a few years later, Zhang Jun began to send Fei Ge and Nanxiong out to find the ground sloth and giant rat cubs, catch them, put them in a special breeding environment, and raise them in captivity.

Due to the huge strength of the ground sloth and giant rats, it is more difficult to trap them, so Zhang Jun must choose a reasonable breeding environment.

After thinking about it, Zhang Jun thought of developing a special kind of underground farm, that is, digging a big pit in the ground, covering a roof on the pit, and driving the earth sloth and other giant beasts into the pit, so that they would not escape.

Of course, the drainage system of the pit needs to be specially designed, and there are also stones to pile up the bottom and sides, and some stairs to facilitate the entry of dinosaurs, which must be isolated from the breeding area with a stone fence to prevent the giant beasts from escaping through the stairs.

This is just one of the options, and it is also possible to breed these behemoths in large caves, although the number of them will be affected by the size of the cave.

After Zhang Jun thought of this, the food problem of Allosaurus was expected to be solved, and he no longer had to deliberately suppress the number of Allosaurus, and he could continue to expand the number of Allosaurus to the ancient scale in the future, when he had as many as more than fifty large Allosaurus, in the Jurassic, this was almost invincible, and now, it is even more unmatched.

The construction of the farm has become the most important task of Zhang Jun in the last 100 years, with the success of breeding, the number of dragons will also increase unprecedentedly, but the number of other intelligent creatures is also gradually expanding, they are also quietly threatening the safety of the dinosaur family, and the dinosaur family is also threatening their development.

In the following days, the dragon herd continued to live half breeding, half hunting, the scale of breeding gradually expanded, the total number of farms has reached ten, the number of more than 5,000, of course, some of the animals are much lighter, but the overall can meet the needs of a thousand dinosaurs.

The breeding of ground sloths, giant rats and elephants has also achieved a certain scale, with a total of about 500 animals, and these foods are prepared for Allosaurus, and the young dinosaurs of Allosaurus complete the breeding task.

In this way, the annual food volume of Allosaurus can also reach about 1,000 tons, and according to the demand of an adult Allosaurus to consume about 200 kilograms of food per day, about 60 tons of food are needed a year, so this is only the food amount of a dozen adult Allosaurus.

Combined with the wild food obtained from hunting, there were already twenty adult dinosaurs in the Allosaurus herd at this time, and the overall number had doubled to about fifty.

In addition, the number of large wyverns in Feige has also expanded to about fifty, including ten adult large wyverns, and the population is also growing unconsciously.
