A few days after sending off Du Dan's family, Xu Jingzong, who had not shown up for a long time, came to the villa to report that the first calf had landed smoothly.

The gestation period of cattle is about 280 days, and the calculation method is generally the same as that of humans, which is also subtracted by three months and added by six days. The cows that Li Shimin sent over began to become pregnant one after another in February, and now that the time is counted, it is time to come.

Yuemei and the others, who got the news, excitedly followed Yin Qingfeng to their new residence in Nanshan. For those who have never seen a livestock give birth, going to see the calves is definitely something new.

From the twentieth to the end of all three hundred cows, dystocia did not occur, which made Yin Qingfeng very relieved.

According to Xu Jingzong's statistics, there are 157 oxen and 143 calves, and the ratio of males to females is basically close to 1 to 1.

Yin Qingfeng planned to wait for two to three years later, when this batch of small calves reached maturity, they could replace the first yaks.

Therefore, the first batch of yak Yin Qingfeng will only leave about 50 heads, and the remaining 100 heads will be sent away when they are one year old, along with the current father and mother.

After that, every two years, some of the paternal and female parents are basically eliminated to ensure the best genes. It is estimated that after three or four batches are eliminated, the parents of the farm will be finalized.

After all these cattle have calved, it is necessary to take advantage of the empty period to strengthen their nutrition and prepare for the next mating.

Too good feed and little activity of the cow can make the cow overweight, which is not conducive to its reproductive performance. Therefore, Yin Qingfeng repeatedly emphasized it a few times before he could be relieved.

Yin Qingfeng doesn't have to worry too much about the cow's affairs. But thinking of those Dawan horses, Yin Qingfeng had a headache again.

Dawan horses belong to desert horses, and it is no problem to use them in the Western Regions in the future. But the main enemy of Datang is in the north, which is the grassland area, and whether Dawan Ma is good or not is it good to use, this is two words.

Considering the cold climate in the north, Yin Qingfeng thought of Haomen Ma. Although the Haomen horse belongs to the forest horse, its living environment is a cold climate. If the Tang Dynasty were to go to war against the north, a cold winter would be unavoidable.

The Turks now control the output of horses, and the Haomen horse may be a good choice. In addition, the river horse is also a good choice.

Yin Qingfeng didn't know what kind of horse breed the military horses of the Tang Dynasty were based on. However, it is necessary to tell Li Shimin about the characteristics and origin of these two # horses.

The origin of Hequ horse is at the junction of Sichuan, Gansu and Qinghai provinces. The production area of Haomen horse is in the Qilian Mountain area north of Qinghai Lake, which should be the territory of Tuyuhun.

It seems that if Li Shimin wants to deal with the Turks and open up the Western Regions, just because of the factor of war horses, he must first destroy Tuyuhun. Only by occupying Tuyuhun and completely blocking the road to the south of Tubo can we operate the Western Regions with peace of mind.

In order to be able to do this, Datang not only has to go over, but also the people. If you go, you have to eat, and you have to have a house. But who wants to move there? How?

Yin Qingfeng, who had a headache in his head, patted his head, why was he thinking about horses, and now his thoughts were running to immigrants again? What are you doing with your heart, let's give Li Shimin a headache!

This year, according to Yin Qingfeng's requirements, Nanshan New Home also introduced sheep and goats.

Although sheep and goats are called sheep together, they are animals of the same family but different genera, so they cannot mate with each other#.

In terms of taste, sheep meat is better than goat meat. Goats have a greater smell than sheep.

In traditional Chinese medicine, goat meat is considered to be cold, while sheep meat is hot. Therefore, the latter has the effect of nourishing and is suitable for pregnant women and patients; For the former, it is best for patients to eat less, and ordinary people should avoid eating after eating, and it is best not to eat cold foods and fruits.

Yin Qingfeng has so many daughters-in-law, so naturally he has to make up for it.

And goat's milk is more easily absorbed than cow's and human milk. The fat of goat's milk is unsaturated fat, and the fat of cow's milk is saturated fat; The nutritional elements of goat milk are comprehensive and rich, close to human milk; Goat's milk is weakly alkaline, and cow's milk is weakly acidic.

Yin Qingfeng is ready to introduce a new way of eating after the flock reaches a certain number. How can shabu mutton be without sheep? And how can lamb skewers be missing goats?

Because it is necessary to wait for the cow to give full birth, Yin Qingfeng returned to the city for the New Year's day is delayed again and again, and waited until the evening of the 28th day of the lunar month, after the last calf was born, Yin Qingfeng set off with confidence.

Before I go back, I have to go to the school to meet the new teachers.

Since more than 200 people came, Yin Qingfeng also glanced at them from a distance at the ceremony of the formation of the new village.

The school is about to open in the first month, and if these teachers don't teach seriously, the headache can only be Yin Qingfeng instead of those teachers, so he must appease them.

Before Yin Qingfeng went to school, he didn't let anyone inform him, he wanted to see the real side of these teachers.

The school is surrounded inside the new village, so the school gate is not locked.

The whole school was quiet, and there was not even a single figure on the playground. However, when the carriage drove to the dormitory, some teachers rushed out of the building one after another.

Although they didn't say hello to Yin Qingfeng, they had seen Yin Qingfeng's appearance when they moved into the new village, so they were very nervous to greet each other.

Facing Yin Qingfeng, who knelt on the ground, he had to accept it with a wry smile. After Yuemei motioned for these people to get up, Yin Qingfeng said: "It stands to reason that I should have met with you a long time ago, but there have been too many things for a while, so it has been delayed until today." How's it going, how are you staying and eating here? ”

Hearing Yin Qingfeng's explanation, these people relaxed a little. Yin Qingfeng, as their current master, didn't need to explain anything, but Yin Qingfeng did this, and they felt Yin Qingfeng's humility and respect.

A teacher standing in the front row bowed down and said, "Hui Langjun asked, everything is fine here for the slave maid and the others." ”

"I invited you from King Qin to teach the children here to read. Since you are female gentlemen, you will be exempted from prostration, and you will be given white silk garments.

I have only one request for you, that is, to help me teach these children well, if you have any requirements or difficulties, you can put forward them with me and Ren Niangzi and Fan Niangzi.

If some of you want to be reunited with your family, I will not object to it, and I will issue you a certificate of good standing when you leave. For those who haven't left, I hope you will make this your home in the future. ”

Seeing that they were a little excited, Yin Qingfeng waved his hand, "Don't say those words of gratitude, as long as you can teach those children well, it will be the best reward."

This time, in addition to bringing you some books as a pastime, each of you will be given 30 yuan for your expenses during the New Year. Taking advantage of the opportunity of the holiday, you can go to Chang'an City together to buy some of your favorites.

From the time you start teaching, you will get five times a month, and I hope you will not be too little. ”

I have to say that the system of this feudal society is really scrambled eggs, and Yin Qingfeng's simple words made these people cry bitterly.

Leaving the humble campus, Yin Qingfeng also sighed when Li Shimin would be able to take the position. If Xiao Li Tong's shoes are on the top, he won't have to hide some things.

But Li Shimin's means of being in the position are really-up. From Yang Guang to Li Shimin, there have been two murders of brothers and heirs in just 20 years, what does this make future generations think?

What else can you see? Imitate, of course! What is the root cause of the rebellion of Li Chengqian, Li You, and Li Shimin's two sons? Obviously.

As soon as he thought of these things, Yin Qingfeng's brain ached for a while: This brother-in-law is not good! This son-in-law is better inappropriate!

It has been eight years since he was a martial artist, but Yin Qingfeng has not yet found a chance to sit down with Li Shimin and have a good chat.

Li Yuan occupies the Yang family's country, which is no problem, but Li Shimin's killing of his brother and taking the heir is a moral problem.

What is morality, is the core and bottom line of the three views of the Chinese! Li Shimin has broken through the lower limit of morality, how much better do he expect his children and grandchildren to be?

"Riding a horse, why didn't God throw the young master ten or twenty years earlier into this time and space? Otherwise, why bother thinking about all this?

Li Shimin's broken ship has already gone up, and it is impossible to think about it. Let's figure out how to find a chance to have a good chat with my ambitious father-in-law, hey~~~"
