Of course, Marin didn't put all his hopes of looking for jatropha in the area around Beaumont. In addition to sending an expedition to Beaumont, Marin also sent an expedition to the Florida peninsula. After all, the climate of the Florida peninsula is very suitable for the growth of jatropha trees, and it is quite possible to find wild jatropha trees there.

In addition, jatropha may also be found in the Central American region. Therefore, Marin also sent an expedition to Cuba, and Tara assisted them in finding jatropha trees.

This is because, in his last life, when he watched TV programs, he only heard that jatropha was "native to the southern region of North America". Cuba, including the entire Caribbean, is considered North America, and it is also the "South of North America". Maybe there are wild jatropha trees on the island of Cuba. Moreover, the island of Cuba has been developed for a long time, and with the help of Tara, a local snake, it is much better to find conditions than to go to North America.

But in that colony on the Florida Peninsula, Marin was not so concerned. After all, the Florida peninsula has neither the oil fields that Marlin values or the prairies where bison can be hunted. As such, the colony was purely a temporary base for jatropha trees. Once the mission is completed, it is estimated that the stronghold will be abandoned. Unlike Beaumont, Marin was intended to be the base camp in southern North America.

In the future, there will definitely be a city on the Beaumont side, plus an inland port terminal. At the same time, a cement road will be built to lead directly to the North American prairies in the inland area, so that the cavalry can go out to hunt and bring back the dried meat made of the North American bison......

In addition to the large amount of meat that can be obtained by hunting bison, the vast grasslands that are vacated after hunting bison are also excellent pastures for grazing.

At present, Beihai has bred Beihai sheep that produce fine wool, and also focuses on cultivating Dongfri raw sheep with large milk production. If you control this part of Texas, you can take advantage of the excellent pastures in the area and raise a large number of North Sea sheep and East Fried sheep. Then, grazing some more cattle and it would be even more perfect.

In addition, Marin plans to use the North American bison to improve the breed characteristics of European domestic cattle. Marin remembers that in his previous life, the Yankees used North American bison and European beef cattle to cross to breed the Piflo cattle.

Piflor cattle are stronger than European beef cattle (after all, they have bison blood) and are more resilient and can withstand bad weather such as blizzards. Moreover, it has high fertility and meat quality, and it produces a lot of milk.

Of course, in this era, the quality of meat and milk production are secondary. Its strong characteristics are what Marlin values the most.

Because of the lineage of the North American bison, the Piflo cattle are stronger and more powerful than the European beef cattle.

This feature will be of little use in the afterlife. But in this era, the role of cattle farming is huge!

North American bison is different from ordinary cattle in that they have strong endurance but poor explosiveness. Cultivated land or something, slowly, affects the efficiency of cultivated land.

The North American bison is a high-speed cattle, which can run at a high speed of fifty or sixty kilometers, which has reached the standard of high speed. It can be seen that the explosiveness and flexibility of the American bison are far better than that of ordinary domestic cattle.

Marlin also sees this as well, and when crossbreeding, in addition to eliminating the fierce breeds with bad tempers, the speed and explosiveness of the cattle are also important traits that need to be preserved. Because, explosiveness and speed mean faster ploughing......

Cattle have a strong stamina, and if their explosiveness and speed also come up, then there is nothing to do with horse ploughing. Of course, when cultivating new varieties, it is also necessary to pay attention to the problem of breed temper.

If a hot-tempered cow is bred to fight to death like a Spanish bullfight, it's doomed. So, this requires several generations of observation and targeted breeding of crossbred cattle breeds. It is necessary not only to retain the advantages of strong explosiveness and speed, but also to control the temper of cattle and avoid breeding violent cattle that threaten human safety.

Although Beihaiguo has produced a single-cylinder diesel engine, it is possible to get a hand-held tractor. But because the production of diesel is too small, it is simply not possible to widely use tractors in agriculture.

Therefore, for a long time, before oil can be mass-produced, cattle and horses will still be the mainstream of the world. However, the endurance of horses is not good, and the requirements for feed are high, and the cost of feeding is high. Eastern European Mongolian horses are not picky eaters, but their physique is too thin to compare with Western European horses.

In this way, if you can cultivate a kind of cattle with explosive power that is not much worse than that of horses and has strong endurance, it will become the best choice.

Even if the crossbred Piflo can't run the 60 km/h speed of the North American bison, as long as it is much faster than the European cattle, it is enough. Because the speed of ordinary cattle is too slow, even if many cattle are used to plow the cart together, the amount of arable land per day is difficult to exceed 15 acres. If there are enough horses, the amount of arable land can exceed 30 acres per day......

There's no way, ordinary scalpers are slow, and if they don't smoke it, they won't move forward. If it is used to pull a plow, the cost of raising is much lower than that of raising horses, but that speed is really anxious......

Therefore, Marin intends to make the breeding of fast Piflo cattle a very important goal.

If the fast, tame and obedient Piflo cattle can be bred, the ox cart may not be an important means of transportation in the future......

In fact, Marin's request is a bit nitpicky. Because speed and docility are often in conflict with each other......

Generally speaking, those cattle that are more docile and obedient are chronic and cannot be speeded. And those cattle that are fast are often more anxious. Otherwise, I wouldn't have to run.

Therefore, Marin's requirements for the cultivation of Piflo cattle simply made it difficult for those animal husbandry experts. After all, a good-tempered cow can't go up at speed, and a cow with a good temper often has a bad temper......

However, Marin is the boss, and he has the final say. He said that he wanted fast and good-tempered cattle, and the animal husbandry experts had to do so. In this way, it is much more difficult to select and breed new breeds of Piflor cattle.

Therefore, in the future, the cattle that will be bred in the end will definitely be a breed that compromises in all aspects. For example, the speed must be reduced, and it will not reach the 60 kilometers per hour running speed of the original Bison. At the same time, the temper will also become a little bigger than that of ordinary scalpers......

In the end, animal husbandry experts can only find a balance between the two, and try to breed the best comprehensive performance, both of which are acceptable.

In the end, Marin also knew that it was a loss, and took the initiative to lower the standard - there is no requirement that the crossbred Piflor can run at a speed of 60 kilometers per hour of the genuine North American bison. However, the speed of 20 kilometers per hour is still needed, that is, the speed of the bicycle in later generations.

This speed is already one-third of that of the original North American bison. But if you can achieve this speed, it is also very strong. Because, the speed of the carriage on the official road is no more than that. Moreover, the endurance of horses is nowhere near that of cattle. If the newly bred Piflor can reach this speed and the temper is not too bad, the ox cart of the Pivro cattle may become the main transport force in the future...... After all, cattle have much stronger endurance than horses, and their feeding requirements are even lower......
