On the way back, Chen Cheng asked Wang Kai more information about Lao Xu.

After having an in-depth understanding of Lao Xu, Chen Cheng decided to bring Lao Xu with him in the future on pig raising and research.

As a classmate and a reliable person, he can rest assured that some of the technology will be handed over to him.

It's just that about the Iasi black pig, how to breed and how to study, Chen Cheng still doesn't know how to figure it out.

After all, he had spent all his time specializing in crop cultivation techniques, and he really didn't know anything about farming.

It is necessary to learn this knowledge as soon as possible, and at the same time develop a system and start to enter the research of livestock breeding technology in earnest.

"Lao Chen, you have so many things to do every day, why do you suddenly go to animal husbandry research?" Wang Kai asked.

Chen Cheng thought about it and decided not to tell him about the great truth of poverty alleviation and changing the countryside, but took out a piece of smoked meat from his schoolbag.

This is in the car, and Zhou Kai they have to fortress for Chen Cheng.

Just as the peasants had to stuff into the car, Zhou Kai and they also forcibly stuffed Chen Cheng with two pieces of meat.

At this time, it was just taken out to explain the reason to Wang Kai.

"Call Ding Tao and them, and Lao Xu. We're going to cook meat in the lab tonight. Chen Cheng said.

Wang Kai cheered and took the initiative to wash the rice cooker.

The rice cooker has been used several times in the lab since it was taken out of the roof of their dorm room.

After a while, Ding Tao and they came. Here, Chen Cheng's meat has also been cut.

It's simply boiled smoked meat in white water without any seasonings.

Chen Cheng first asked Wang Kai to introduce Lao Xu to Ding Tao and them, and then introduced them to a few people around the small table.

"This is the Iasi black pork that I brought back from Iasi County today. Please taste how delicious it is without any seasoning at all. ”

Wang Kai scoffed: "How delicious can pork be without seasoning?" ”

Ding Tao also said: "There should be a smell of commotion, right?" It's smoky, but it certainly won't taste good there. ”

Chen Cheng ignored them, directly put a piece into his mouth, and ate it beautifully.

Wang Kai and the others also ate a piece in disbelief.

"Huh?"

Wang Kai's eyes widened and he turned his head to look at Chen Cheng.

"Lao Chen, the taste of this pork is different from all the pork I've eaten before!"

As he spoke, he shoved another piece into his mouth.

Ding Tao was also full of praise, and Tang Qiang silently stuffed several pieces into his mouth.

is still Lao Xu, he is engaged in pig breeding, so the tasting is more professional.

"Lao Chen, the meat quality of this pig is more delicate than that of ordinary pigs, and the taste is pure, there is no peculiar smell, and there is a surging fragrance and sweetness. Is this the breed of the little pig you brought back? ”

Chen Cheng nodded.

"According to the locals, this pig is not too big in size when it grows up, no more than 100 catties, and can only be fed with hogweed to maintain this taste. And it is not clear whether it is necessary to breed at high altitudes. So I want to do a good job of research. ”

While eating meat, Wang Kai nodded again and again: "Hmm... It's time to study it, this meat is so delicious. ”

Chen Cheng said: "It's such delicious meat, but few people can eat it." Nor can farmers make a fortune by breeding these pigs. ”

"Why?" ×4.

Several people think that such delicious pork should be very marketable.

Chen Cheng said: "Because this kind of pig can only be raised in the alpine area of Iasi County at present, it has such good quality. So the yield is extremely low. ”

Wang Kai and a few others stopped gobbling up, and their expressions became lonely.

The yield is not high, on the one hand, farmers cannot make money, and on the other hand, consumers cannot eat this good thing.

This should be regarded as a very sad thing for people who are engaged in agricultural technology.

Lao Xu said slowly: "That's the case." We have a lot of pigs with excellent meat quality in China, but because of the low meat yield and long feeding cycle, these breeds have been gradually eliminated. Now we see almost all the white pigs imported from abroad. ”

Seeing that Chen Cheng and others were interested in listening to this history, Lao Xu put down his fast son and told the story.

"As we all know, we Chinese people love to eat pork, and now China consumes more than 50 million tons of pork every year, accounting for more than half of the global market.

In fact, the traditional Chinese pigs are all black-skinned and black-haired pigs, with many varieties and a good taste, but the meat yield is indeed very low. After the seventies and eighties, with the improvement of China's national living standards, people's demand for pork consumption is increasing, and the original black pigs can not meet the market demand, so they began to import white-skinned pig breeding pigs abroad. ”

"Pigs abroad are almost all white-skinned. The more common ones are Landrace pigs, York pigs, and three Duroc pigs. These breeding pigs have the advantages of high growth rate, high lean meat content and high feed utilization, which has indeed greatly improved the output of pork in China and met people's demand for pork. ”

"However, the quality of the pork is not satisfactory."

Wang Kai was surprised: "No wonder I heard the old people in my family say when I was a child that pork tastes different now than before, and even the meat is not as fragrant as before." ”

Lao Xu nodded and said, "That's right." The quality is different, and the current pork is not as good as the taste of the Chinese black pig no matter how it is cooked. The main reason is that the way of raising and the breed of pork have changed.

At that time, most of the black pigs raised in China's rural areas were raised, and now the countryside and pig farms are breeding white pig breeds imported from Europe. ”

"In the past, the black pigs raised in the countryside needed to be raised for a whole year before they could be slaughtered and eaten meat, and most of the pigs were only about 110 kilograms when they were slaughtered. Now the imported white pig breed can be slaughtered in half a year, and the weight can reach about 150 kg.

Although white pigs grow quickly to meet the needs of more people, the quality of pork is declining, and it tastes only protein and does not taste good, and people who have eaten black pork will unconsciously dislike white pork. ”

After listening to Lao Xu's answer, Chen Cheng and the others all fell into deep thought.

The introduction of white pigs is not a wrong thing, but the mistake is that when we introduced white pigs, we gave up the cultivation of our traditional breeding pigs.

"Why don't we breed Chinese black pigs?" Ding Tao asked.

Lao Xu sighed and said, "We are all engaged in agricultural technology, and you also know how long it takes to cultivate a new rice variety, and the breeding pig is longer than this rice." Because the genetic stability of mammals is much higher than that of plants. Besides, animals don't cross as easily as plants! ”

Chen Cheng looked at Lao Xu approvingly, and through these few words, it can be seen that Lao Xu's breeding technology is very high and his theoretical knowledge is very solid.

"Breeding pigs is low in profit, has a long cycle, and it is easy to lose money. Therefore, apart from research institutions, few people in the private sector are willing to breed new pig breeds. ”
