Because spring plowing is imminent, Ma Lin ordered to complete the replacement of land as quickly as possible, so as not to delay spring ploughing. The petty aristocrats and Junker landlords who were not "their own people" were relocated to the west bank of the Elbe. They were accompanied by their former serfs and livestock.

Originally, it was nothing. However, Marin's subordinates suddenly reported an incident that attracted Marin's attention......

It turned out that many of the smaller nobles and Junker landlord families in West Frisland brought a lot of livestock with them when their families moved...... Of course, that's not the point, the point is that there are a lot of black and white cows in their herds......

Holstein cows, also known as black and white cows, are the best breed of dairy cows in the world. The largest source of this type of cow is none other than West Friesland.

Previously, Marin had been a strong promoter of the dairy industry. However, there is a lack of good cows. Therefore, Marin sent people to West Friesland, as well as North Holland and other places, to buy a large number of black and white cows. Unfortunately, the local landlords are not willing to sell too much, only a small part.

So, Marlin didn't buy many black and white cows later. This incident made Marin deeply regretful.

However, during this great migration, Marin's men found that the small country nobles and Junker landowners from West Friesland had a lot of black and white Holstein cows in their hands......

And Kohler's subsequent investigation surprised Marin even more - the West Frisian region has as many as three or four thousand black and white cows. Moreover, a third of them belonged precisely to the small West Frisian nobles and Junker landowners who were relocating......

I was tired and spent a lot of money before, but I only bought a few hundred black and white cows. Now, three or four thousand black and white cows were placed in front of him, and Marin's eyes suddenly turned red......

After walking around the office with his hands behind his back for a long time, Marin finally made up his mind. So he called Kohler and ordered:

"Kohler, you go and bring people to forcibly buy the black and white cows in the hands of the relocated West Frisian nobles and Junker landlords!"

"What if they won't? After all, without cows, they don't have milk and cheese. Kohler asked.

You must know that these little nobles and Junker landlords are very particular about the quality of life. Taking away their cows is equivalent to denying them milk and cheese, and the quality of life is definitely going to drop a notch.

Ma Lin thinks about it, these little nobles, and Junker landlords, although the money is not too much, but in life, they are very particular. Even if you don't have money, you're poor. This is a common problem of nobles and children of nobles, otherwise, there would not be a situation where most nobles are in debt.

If these people were deprived of milk and cheese, they would indeed be grumbled. But Marlin really wants those black and white cows!

What does Marlin want these black and white cows for? Naturally, it is concentrated to expand and reproduce! Three or four thousand is too little, and he needs to expand the number of black and white cows to tens of thousands.

Moreover, Marlin plans to feed the cows with the best alfalfa grass and some oats and beans to increase milk production.

At the same time, Marin will select the best veterinarians from the disciples of two Mongolian doctors, Mozhigen and Battle, to professionally serve these black and white cows, so that the health and life of the cows can be guaranteed. Of course, the aim is to achieve mass reproduction and expand the population.

The ultimate goal is to achieve mass production of milk.

What does milk do after mass production? Naturally, it is for the children of the Grand Duchy of the North Sea! Among them, the children of nobles and military families will be given priority. Then, then there are the other children.

In addition, milk production has increased, and it is more convenient to drink milk tea. If you don't have enough milk, where does milk tea come from?

Of course, if the milk production is large and the supply exceeds the demand, the excess milk can also be concentrated and heated to remove water to make milk powder. In this way, it is more conducive to long-term storage.

When Marin's dairy breeding center expanded and the number of cows increased, Marlin would also export the cows and sell them to other countries and send them to the colonies, so that everyone could drink milk.

In fact, as long as it is a cow, it can produce milk. However, the milk production of black and white cows is several times that of ordinary cows, and can reach the level of several tons per year. Cows have a long lactation period and can produce milk for a long time. While feeding the calves, it can also provide a large amount of milk to humans. Ordinary cows, on the other hand, produce more milk than cows, and it is difficult to supply humans in large quantities.

That's why Marlin attaches so much importance to the cultivation and expansion of black and white cow breeds. As long as there are enough black and white cows, then more people can drink milk.

Moreover, black and white cows have a good characteristic - that is, they are very adaptable......

In addition to being somewhat unaccustomed to the heat, black and white cows can adapt to most climates and are relatively hardy. Therefore, this kind of cow not only produces a large amount of milk, but also is very suitable for promotion to all parts of the world. Therefore, the dairy cows of later generations are popular all over the world......

The reason why Marin wants to build a unified dairy cow breeding center is to optimize breeding. The so-called optimal breeding is to select the best male and female cows to breed in order to give birth to high-quality young cows. When these young cows grow up, they become the new main milk producers.

It is important to note that male cows do not produce milk, but they are very important. Because, without the cooperation of male cows, female cows do not produce milk...... Do you let a big girl milk a cow?

Therefore, it is very important to select healthy and high-quality male cows, which will affect the quality of the next generation of dairy cows.

It's just that Marin found that people in this era are very concerned about the cultivation of dairy cows, and they just find a bull and breed it. Even, Marin has seen dairy farmers who randomly find a bull that is not a black and white cow breed and breed it, which is simply a mess......

It is no wonder that Europeans in this era still only paid attention to human blood, and ignored the bloodline of livestock. The breeding of professional horse breeds in later generations will not be carried out until the 17th and 18th centuries.

Of course, Marin believes that there is no noble bloodline in people, and there is no need to find the strongest male and female to breed...... In fact, it is not human beings who conquer the world by being strong. If you are strong, it will be animals like elephants and rhinoceros that will conquer the world...... The most important factor in human beings should be wisdom......

Of course, as a human-raised animal, the standards are different. For human-raised animals, being strong is an important principle. For dairy cows, milk production is the standard......

Therefore, from the standard of optimal breeding, the selection of dairy cows is to select strong bulls and breed with cows with large milk and more milk to get better cows......

……

To this end, Marin plans to gather all the three or four thousand dairy cows in West Friesian land and establish a large dairy cow breeding center to optimize breeding and breeding, so as to expand the population of black and white cows and improve the milk quality of dairy cows.

As for the small West Frysian nobles and Junker landlords who were robbed of their black and white cows, Marin also decided to make some compensation, these petty nobles and Junker landlords raised their cows not to make money, but to consume them for their own consumption. Because, there are not many ordinary people who can afford milk......

So, Marin decided to compensate for the selection of a corresponding number of cows from the cattle purchased from the Crimeans as compensation. At the same time, pay some extra money to make up for the difference in value. In this way, they are worthy of them. After all, Crimean cows, although they do not produce milk as much as black and white cows, can also produce milk.

As a result of this forcible purchase policy, Marin gathered together three to four thousand black and white cows in West Friesland, as well as the hundreds of black and white cows he had bought, and established a large-scale dairy breeding center near Aurich.

Of course, because the Holstein cows produce a lot of milk, the breeding center can also supply fresh milk to Aurich and nearby Emden.

As for the excess milk, afraid of spoilage? It is processed into milk powder and preserved. Anyway, Marin now has a lot of oil paper in his hand, and he is not afraid of not having a bag to package milk powder...... As for the milk powder brand, Ma Lin thinks that the brand "Sanlu" seems to be good......
