Director Lu gently opens the brochure made by the genetic engineering laboratory.

Under the conditions of 1985, the adjectives commonly used in propaganda such as "picture and text" can not be prefixed.

However, Yang Rui still tried to make the brochure more eye-catching.

On a piece of paper, he used a variety of sizes of font, and the depth is different.

Don't underestimate this requirement. In the era of no computer typesetting, the production of any printed matter is quite complicated.

Yang Rui also owns a publishing house with Shi GUI. With the latter's intervention, he can easily print the desired finished product. He can even change it as many times as he wants, but he has not been hacked to death by art workers.

Director Lu is very serious.

In the eyes of their generation, the handwriting on any printed matter seems to be related to the truth.

If it is related to their own professional information, it is even more difficult. Many people will copy down the professional books when they get them, which is the same reason. They are worried that they will never find the books after they return them.

The actual situation is exactly the same. The number of libraries is limited after all, and the number of books that a library can hold is even less. In addition to the famous Peking University Library and other institutions, the number of books in most domestic libraries is 10000. Of course, there are also libraries with thousands of books, But most of them should be called libraries.

However, no matter tens of thousands of books or thousands of books, it is impossible to cover the knowledge system after the 20th century, and professional books are even more precious.

Moreover, except for a few wealthy units, the cost of buying professional books is also very high. At the wage level of tens of yuan per month, any book with a price of one yuan has to make intellectuals hesitate again and again.

From the perspective of Lu Chang Chang Chang, the pamphlet Yang Rui used for publicity has already been popular science.

As a result, it is true.

In a few pages of pamphlet, Yang Rui described in detail the classification and marketing methods of beef abroad. In addition, there are also some breeding techniques of Simmental cattle.

The content is very simple. If you search in the network of Chinese journals, there will be at least ten similar articles.

But for Lu Changchang and others, it is still the same problem. They have no network, they can't see all the journals, no one can see them, and no one can master all the information.

Any valuable knowledge is of great value in the 1980s. To some extent, it is even more valuable than 100 years ago.

Because the 1980s is an era of technology transformation explosion - although there are countless people criticizing that the whole society has not invested enough in technology transformation, the reality is that China in the 1980s has invested more resources in technology transformation than in the past.

From the lack of food and clothing in the late 1970s to self-sufficiency in the 1990s, what happened in this decade or 15 years is beyond the imagination of the media reporters sitting in the office with their legs up.

It's true that the technological transformation in the 1980s was very low-end, but they adapted to the times, just like the life of burning whole coal was replaced by the life of burning honeycomb briquette. Their technological content was very low, but it was a real technological transformation, and their impact on society was not low at all.

In the brochure written by Yang Rui, there is no profound knowledge, that is, some skills of storing feed and fattening.

But that's why Lu Chang paid more attention to it. After carefully reading the brochure, he carefully put it back in the envelope and carefully collected it in the coat pocket.

It has to be said that Yang Rui's fame is also a catalytic factor.

If ordinary college students take a pamphlet, even if he takes the time to read it, he won't pay much attention to it.

But the things Yang Rui took out were different.

There are some celebrities in the field of animal husbandry. Professionals or researchers are not young and old, but they are as famous as Yang Rui, especially few who attach equal importance to both professional and social fame.

Not to mention, Yang ruicai has just made the embryo transfer technology of cattle which has not been made in China for a long time.

You know, this thing is going to be included in the 863 plan, the so-called national high-tech development plan. You can see from its name, its technological content.

Yang Rui has made such achievements. He has to take back the brochures he wrote, even the things that director Lu already knows, and study them carefully, let alone the things he doesn't know.After reading the booklet and putting it away, Yang Rui and other leaders of Lu said, "at present, the fastest embryo transfer for cattle is Zhongmu. It takes about a month to give them 10000 embryo transplants. However, the 10000 cows they want are all cows. You know, cows grow slowly and are hard to sell. It's more difficult to make the first batch of export products. "

"Yes." Long Lu bowed his head and pondered.

"On the other hand, the veal that foreigners like to eat is veal, and they won't sell 80 day heifers. Normally, in foreign countries, there is a limit on the number of cattle and sheep in their pastures. If the number is too large, it will not grow well. It is better to kill the extra bulls, which is the same as catching the cocks when we raise chickens in our country... "Yang Rui made a brief introduction and said:" in a word, Zhongmu has no time to participate in the first wave of foreign exchange earning tide, and the rest, Whoever buys the bull early has a chance to earn foreign exchange first. "

Cows will not be slaughtered in foreign pastures. Those pastures that specially raise bulls to sell meat usually purchase calves directly, while comprehensive pastures or family pastures mainly keep cows as capital and sell bulls as working capital.

The living environment of male animals is so bleak. In most pastures, except for a few bulls left to breed cattle, the remaining bulls are no more than 80 days or 380 days. Bulls who can live to 500 days are lucky.

It's not many that want to be a shelf cow for a year or even a year and a half, and then fatten for three to six months, just like the cattle in the hands of domestic farmers.

Long Lu pondered for a while and said, "what's the price of 80 day veal sold abroad? Do you think it's worth 3000 yuan from a ranch? "

Raising cattle is not without cost. Milk is still consumed by calves in the early stage, and pregnant cows need better feed to supplement nutrition, which means higher breeding expenses

"In foreign countries, veal is slightly more expensive than ordinary beef, and it's not too expensive." Yang Rui directly gave Lu Chang Chang Chang the answer he wanted to ask, saying: "if you want to make a detailed account, you will spend 3000 yuan for embryo transfer of cattle, and only raise it for 80 days. It must be a loss."

"That's also..." Mr. Lu wanted to say that no one would do this in China. He opened his mouth and stopped again. He knew that someone might do this. After all, it's the country to earn more and less, and it's his own to earn foreign exchange, get promoted and get rich.

Therefore, there must be people who would rather lose money than keep it for 80 days. After all, the loss is RMB, which can be made up from all aspects of the ranch, but the profit is foreign exchange, which is nowhere for the ranch to make up.

"180 days?" Mr. Lu asked again.

Yang Rui said slowly: "the price of 3000 yuan embryo transfer is estimated to be difficult to earn back."

180 It's impossible to earn hundreds of dollars by sharing the weight of cattle in the unit price. Moreover, the feed cost is also a big problem. The smaller the cattle, the better they will eat, and the higher the feed to meat ratio.

Lu long some understand, tentatively asked: "if I use 1000 yuan to buy embryos, raise 180 days can earn?"

"It's almost the same. I won't lose too much in 80 days." Yang Rui smiles.

At this time, director Jiao put in a word and said, "so, no matter how you say it, Lao Lu, you are making a lot of money when you sign this agreement."

"I'm afraid I'll be scolded by farm workers for selling yetian." Lu Chang said, but he had made the final decision in his heart.
