"Does the sperm of a cow decide whether it is a bull or a cow? You know the X and Y chromosomes. Some of the bull's sperm have Y chromosomes, and some do not."

Jiang Zhijun was stunned for a moment and nodded.

Yang Rui continued: "Flow cytometry can be transformed into an assembly line cell separator. When you want a cow, the flow cytometry will rotate and separate the bull sperm that is all X chromosomes. The artificial insemination will be all cows. Otherwise, artificial insemination will be all Y chromosomes, and all bulls will be all. It is very convenient and has a high resolution."

Jiang Zhijun was stunned when he heard this: "It's just that after the instrument is changed, I want the male and the female and the female and the female?"

"Yes. Pass the cow's ** through the flow cytometer, and the male and female separated when they are in liquid state." Yang Rui stroked the air with his hands twice, which was a explanation of pictures and texts.

"Is foreign technology so advanced?" Jiang Zhijun said with some envy.

Yang Rui curled his lips: "What does it have to do with foreign technology? Foreigners are also studying this. It's almost the same for us to intercept him."

"Hasn't researched abroad yet?"

"At least, we have not realized the on-site use, let's make it for him first." Yang Rui looked cramped. To build a gender control system on-site, there must be a site for experiments.

The close relationship between the academic and industrial sectors abroad is also relatively common. Those who do research carry instruments and run to other people's ranches, often using other people's valuable cows for experiments. If you think about it, you will know that there are a lot of nonsense and demands.

Furthermore, there have been various gender control methods abroad, such as the simplest electrophoresis method, which can also separate sperm, or simply use manual methods to give up some embryos. Furthermore, for large foreign technology service companies, it is okay to use different sales strategies after identifying male and female males.

This is the advantage of technology-developed countries.

Because of the competition in existing technologies, the use of new technologies is not as easy as that of late-developing countries.

Yang Rui now buys a few flow cytometers and can be used on bulls from China Animal Husbandry. Such things will not be so convenient for foreign research institutions.

In addition, the development of corresponding supporting technologies is another threshold.

For example, various reagents, corresponding technical parameters, etc., it takes a lot of experiments to measure it. Yang Rui has corresponding data and just needs to find a flow cytometer with similar technical level.

By comparison, his foreign colleagues have more work. If it is normal, it will take almost four years before they can develop various supporting reagents and determine various parameters.

For the genetic engineering laboratory, if Yang Rui designs the original version, it will not be too difficult to work regardless of whether it needs improvement. This is the focus of the next stage of research, and it is still not a heavyweight field, but after all, it is still a world-leading position, and it is still a rare area for a district-level laboratory.

Amidst the chaos, the embryo transfer of 200 cattle was announced to be completed.

Looking at the endless thousands of local scalpers, the CEO of China Animal Husbandry who came to visit was filled with emotion.

"These cows are pregnant with Simmental cows?" The boss was wearing a Zhongshan suit and cowboy boots, looking like he had just been caught by an alien and barely ran back.

Director Mei was very energetic and said, "That's right, and they are all cows from Simmental cattle. In addition, there are more than a thousand embryos, which are now frozen in the cold storage of the Genetic Engineering Laboratory in Haidian District. Their staff are limited, so they separated the male and female first. The female first transplanted to us, and the male first used it after freezing it."

The boss did not ask the husband what the embryo should do, but kicked the embryo on the ground with cowboy boots and continued to sigh: "I didn't expect that when I read books, I thought the story of occupying the magpie's nest was incredible. Now I have seen embryo transplantation."

Yang Rui, who was accompanying him, turned a stiff face and used the magpie's nest to describe embryo transfer. It was really...a bit appropriate.

Director Mei happened to be a little unaware of how to respond to the boss's question. Seeing Yang Rui's expression, he immediately pushed him out.

Amid the warm smiles of middle-aged and elderly officials, Yang Rui received a three-minute routine inquiry and was asked questions that everyone was concerned about.

I heard the boss use a very sincere voice, like a hoarse voice after being tortured by aliens, saying, "Yang Rui, when will the remaining thousands of cows be finished?"

"We are now focusing on making the orders for China Animal Husbandry, which will probably take two or three months." Yang Rui replied with equal sincerity.

The boss said in surprise: "It will take two or three months?"

"Yes, it will take at least so long."

"If this happens, it will be the New Year." The boss looked a little worried, and the officials next to him were also like this, and there were low-key discussions.

Director Mei saw that the heat was almost done, and came out to add firewood and said, "Yang Rui, we, the Chinese Maggie Cheung, hope to complete it as soon as possible, the slowest, and we must complete it before the New Year."

Yang Rui smiled bitterly and said, "No one wants to work during the New Year, but there is no way, we have encountered many problems."

"If you have any problems, solve the problem. I'm here today to solve the problem. Yang Rui, you said." When the boss heard Yang Rui's words, he stomped his feet and mud and water splashed everywhere.

Yang Rui thought to himself, you are a little too devoted to the performance, and besides, you are too hard.
