Chapter 135 American pig, be strong!

After the negotiation was over, Zheng Kezang returned to Yizhou Island again.

There was no war in a short period of time, and Zheng Kezang began to focus on the political affairs of Dongning Prefecture.

The explosive growth of the population has brought about new problems, that is, the problem of food production.

Worried about insufficient food, Zheng Kezang summoned the household official Yang Ying to inquire about this year's autumn harvest.

"Your Majesty, the food production situation this year is very gratifying! Please listen to your detailed report." Upon hearing this, Yang Ying opened her eyes with a smile.

It turns out that Yizhou Island has a lot of cultivated land. During the Zhengjing period, the cultivated land area of ​​Yizhou Island had reached 600,000 acres. Now the population has increased by more than 160,000, and the cultivated land area has doubled.

According to statistics from the Ministry of Household Affairs, a large-scale increase in immigration began in August 1681, and cultivated land also began to increase. Including official land, there were approximately 1.4 million acres of land.

However, 800,000 acres of land have been newly reclaimed, and crops have not yet been planted. Therefore, the main productivity is still the original 60 acres of land.

"I understand the general situation. How many acres of land are used to grow rice?" Zheng Kezang asked more carefully.

The Chinese people of later generations are more or less like native pigs. When they see the name of native pig hanging in the market, they are half-hearted.

If Khrushchev knew about the people's love for corn in Yizhou Island, he would definitely be very pleased and smile.

By the middle and late Qing Dynasty, the height of Chinese people had further declined, reaching a historical low.

However, the scientific and technological development of China's animal husbandry industry was too slow, and the breeding level has never been improved. Only then did Westerners use Chinese domestic pigs to improve local pigs, forming a series of high-quality meat pigs.

Based on the data of Chinese prisoners in Australia in the 19th century, Stephen Morgan compiled and analyzed the height changes of the Chinese at that time. The final conclusion of the height trend was that the average height of the Chinese in the 19th century had dropped to 161.5 centimeters.

"Don't underestimate them. If you raise them well, they will be ready for slaughter in half a year. By then, the people will not be able to eat all the meat!" Zheng Kezang said excitedly, stroking a naked little piglet.

Thanks to the unique natural climate of Yizhou Island, the good varieties introduced by Zheng Kezang, and the unremitting efforts of Dongning Zhuanshi, this year's grain output has reached a new peak.

That night, on the outskirts of Dongning Mansion, another new landmark building was about to rise, and that was the Dongning Breeding Farm!

It is run by his closest confidant, the old eunuch Li Zhongjie, and is supervised by officials from the Ministry of Household Affairs.

Although there is a lot of water here, the yields of sweet potatoes, potatoes, and corn are higher.

This was not possible. In order to improve the physical quality of his soldiers and increase the happiness of the people, Zheng Kezang decided to take a stroll in the system mall to see what good breeds of livestock were available.

In the system mall, there are two kinds of piglets that Zheng Kezang likes the most, namely Duroc pigs and Landrace pigs.

Now, with this batch of high-quality piglets, Yizhou Island's surplus grain can not only support Qiongzhou Island, but can also be used to feed pigs, especially corn and sweet potato leaves, which are the favorites of Duroc pigs.

"Half a year! This is too fast. It takes 9 months to a year for an ordinary pig. This is a magic pig!" an official said in shock.

Among them, the planting area of ​​corn is as high as 150,000 acres of farmland, completely exceeding that of rice fields.

"You have to take good care of these little piglets. Whether the people can eat pork every day depends on you!" Zheng Kezang waved his fist to encourage everyone.

Fortunately, Yang Ying knew all these data and said: "Back to the king, out of the 600,000 acres of farmland, about 100,000 acres are used to grow rice. Because sweet potatoes, potatoes, corn and other crops have high yields, people are willing to plant them.

." Corn was a crop that was popularized in the Ming Dynasty during the Wanli period, so people would spontaneously plant corn.

If you eat sweet potatoes and potatoes every day, your nutritional intake will not be unbalanced, and people's physical fitness will become worse.

"This pig looks very sturdy." A small official commented as he raised and lowered his hands on the little piglet.

It's so bizarre.

Landrace pigs are good at everything, but they have one shortcoming: poor adaptability to the environment!

If it weren't for the large amount of sweet potato production, they wouldn't be so active!

Zheng Kezang realized that now is the end of the Age of Discovery, and Westerners, who occupy most of the resources, will be ahead of Easterners in terms of physical fitness.

When these red and black Duroc piglets appeared, the small officials in the Ministry of Revenue were shocked. How could there be a new variety of piglets in Yizhou Island? Why didn't they, the people in charge of agriculture, know about it?

Then we can only use Duroc pigs, which are easy to feed, from the United States in later generations!

Duroc pigs have fewer litters, with an average of only 9 to 10 piglets in a large group, but they grow quickly, have a high lean meat rate, good physical fitness, strong ability to adapt to the environment, and are not prone to disease.

In the middle and early Qing Dynasty, the height of Chinese people was about 165 centimeters, which was a certain decrease compared with previous dynasties.

After listening to the report from the household official Yang Ying, Zheng Kezang found that he was too conservative. It seemed that he still had to immigrate because there was overproduction of grain!

However, Duroc pigs actually have more or less genes from Chinese native pigs.

This was the seventeenth century, and the living environment provided for piglets was obviously worse.

In the era of handicraft industry, China undoubtedly had the best pig breeding resources in the world.

Yizhou Island is dominated by southerners, and white rice is their favorite food.

Especially after the Qing Dynasty, the height of Chinese people dropped to a certain extent.

In order to increase their sense of participation, Zheng Kezang asked the officials to give these piglets names.

[Deduct 50 points, leaving a balance of 690 points]

If you don’t have to worry about food, then you have to eat meat!

Zheng Kezang thought about it and thought it would be the most economical thing to exchange some good varieties of piglets for the people of Ming and Zheng.

These little officials didn't know where they learned that the new King Yanping particularly admired his grandfather Guo's surname, so he named it: Success No. 1.

Zheng Kezang could not explain their origins and simply kept silent about them.

Other officials also discussed it a lot.

The Ministry of Revenue made a rough calculation and found that this year's grain production is about 270 million kilograms. (For statistical convenience, kilograms and kilograms will be used in the future)

Based on the annual food requirement of 150 kilograms per adult, this food is enough to feed a population of 1.8 million.

They were bred in the northeastern United States in the 1860s from New York Red Duroc pigs, New Jersey Jersey Red pigs and Connecticut Red Berkshire pigs.

Now Zheng Kezang's Ming Dynasty is a bit confused. German military uniforms, French guns, British cannons, and now there is an American pig strong!

50 points, 1,000 piglets, bite the bullet, Zheng Kezang changed, this is a good thing that benefits the country and the people.

I heard that Zheng Kezang's head was full of black lines. Fortunately, he was not so cruel, otherwise the head of the official who came up with this name would have been chopped off long ago.

Finally, with Zheng Kezang’s approval, the Duroc pig was named Beautiful No. 1.

Everyone in the household didn't understand why it was called this name. Although the little piggy was cute, it couldn't be compared with beauty.

Only Zheng Kezang knew that the piglets came from a beautiful country.
