Li Zhi stood at the pig farm outside Fanjiazhuang, looked at the dregs fermented by Long Minggui, the person in charge of the pig farm, and nodded. Pen % fun % Pavilion www.biquge.info

Li Laosi stood behind Li Zhi, looked at the paste-like mess, and asked curiously: "Dongjia, can fermented soybean meal be eaten by pigs?" I haven't heard of it. In the past, the soybean meal obtained after soybean refining was taken and thrown away, which was poisonous, and pigs would die of illness if they ate too much. ”

Li Zhi nodded and said: "This fermented soybean meal is a treasure, the dragon is precious, you can take it and feed it to us!" ”

Long Minggui was stunned and said, "Grandpa Guo's golden body!" The inside of the pigsty is dirty, I'm afraid it's not the place where the grandfather and the chief military officers should go! ”

Li Laosi said: "Long Minggui, I fed pigs for a few years when I was a child!" ”

Li Zhi waved his hand and said, "It's okay, let's go to the pig house, you find a few pigs to feed us!" ”

Long Minggui sang, then asked people to lift a bucket of fermented soybean meal, and walked into the pigsty with Li Zhi and others. Li Zhi went into the pig barn and looked at it, and found that it was not particularly dirty. When Li Zhi was building a pig farm, he repeatedly emphasized that he should pay attention to hygiene, and each pigsty was deferated by a special area, and drainage ditches were built in the pigsty. Pig workers carry water twice a day to clean the pigsty. So although the whole pig farm smells, it can be tolerated.

There are pigs of different ages in different areas of the pig farm. On the pigsty are hung all kinds of signs, on which the various parameters of the pigs are written, and it looks quite organized.

It's feeding time, and the keepers are pushing cartloads of pig food into the pens. Long Minggui found a circle of fat pigs and poured the bucket of mess into the trough.

As soon as the rotten fermented soybean meal was poured in, the ten fat pigs in the pigsty rushed over and ate wildly around the trough. Obviously, for the pigs this mess is very sweet, even more delicious than sweet potatoes. It only took half a minute for ten pigs to eat a bucket of fermented soybean meal.

Li Zhi asked, "Pigs don't have diarrhea?" ”

Long Minggui took out a small box from his arms, took out a mushroom cake inside and handed it to Li Zhi to see, and arched his hand and said: "Grandpa Guo, we sorted and cultivated 'fermentation bacteria' according to the method you said, and it took three years to finally find the most suitable 'mushroom seedling'." The previous fermentation bacteria failed to eliminate the toxins of soybean meal, and the pigs got sick and had diarrhea after eating them. But with fermentation seedlings it's a different story, turning toxic soybean meal into sweet pig feed. ”

Long Minggui was a little cautious when he spoke, and the fact that Jin Guogong knew everything made Long Minggui very in awe of Li Zhi. The people all say that the Duke of Jin Guo is descended from the stars, and after Long Minggui made the fermentation seedlings according to Professor Li Zhi's method, he felt that this statement was likely to be true.

Jin Guogong turned stones into gold, turning useless soybean meal into treasures.

"Soybean meal" is the residue left over from soybean oil extraction. This residue is rich in various nutrients, its crude protein content is about 45%, and rich in other nutrients, such as about 1.5% fat, about 12.5% carbohydrates, a variety of minerals, vitamins and essential amino acids in the animal body, especially rich in lysine, which is easy to lack in other plant feeds, its content is as high as about 2.6%.

However, there are a variety of anti-nutritional factors such as trypsin inhibitory factor and soybean antigen in soybean meal. Due to the presence of these "toxins", not only do animals not be able to use the nutrients in soybean meal, but also eating them in large quantities can endanger the lives of animals.

Therefore, in the Ming Dynasty, all the soybean meal that had been refined was discarded, and at most it was buried in the ground as green manure, and no one used it to feed the animals. As a kind of garbage after oil refining, the price of soybean meal is almost free of money.

There's a huge business opportunity buried here.

The best way to get rid of these toxins in soybean meal and turn waste into treasure is to ferment. In the 21st century, before Li Zhi crossed, poisonous soybean meal was one of the most important pig feeds, precisely because of the existence of fermentation technology. Through fermentation by fermentation bacteria, the toxins in soybean meal can be greatly eliminated.

Not only that, the fermentation process can also increase the content of beneficial substances such as active peptides and amino acids, increase probiotics, and make nutritious soybean meal the sweetest pig feed.

Soybean meal fermentation technology can be said to be a milestone technology in the pig industry. As a traverser, Li Zhi naturally will not let go of this technique.

The main source of Daming edible oil is soybean oil, and the amount of "useless" soybean meal produced every month is very huge. Finding this fermentation bacterium and turning useless and worthless soybean meal into a treasure can greatly reduce the cost of raising pigs for Li Zhi.

Of course, the cultivation of fermentation bacteria does not happen overnight. Li Zhi taught Long Minggui the method of sorting and cultivating fermentation bacteria in later generations, and it took Long Minggui three years to poison dozens of pigs before he got qualified seedlings.

It can be said that this mushroom cake is more precious than gold. If a crumb thief from the outside world takes this mushroom cake, he will immediately make a fortune.

Li Zhi looked left and right at the piece of mushroom cake and handed it to Li Laosi.

Li Laosi looked at the mushroom cake left and right, shook his head and said, "This is really amazing!" ”

Li Zhi looked at Long Minggui and asked, "What is the ratio of feed to meat fed with fermented soybean meal now?" ”

Long Minggui replied: "We now feed the pigs with sixty percent of fermented soybean meal, thirty percent of sweet potatoes and one percent of pigweed. If the dead pigs are removed, the approximate feed-to-meat ratio is five to one. ”

Li Zhi nodded.

Long Minggui said: "We contacted the oil refining workshop in Beizhili to buy soybean meal from oil refining waste on a large scale, and we can buy a large amount of soybean meal at the price of two pennies a catty. Coupled with freight, the cost of soybean meal to pig farms is only three and a half dollars a catty. In this way, the feed cost of a pound of pork is only 16 yuan. ”

"Even if the oil refining workshop realizes the usefulness of soybean meal in the future and increases the price of soybean meal, I am afraid that the cost of feed will not exceed 20 yuan."

"Coupled with other labor costs, our pig cost can also be controlled at 23 wen a catty. Now the price of meat in the market is more than 70 yuan a catty. Once our pigs raised from soybean meal are on the market, the price of pork will experience a plummet! ”

In recent years, with the rise in food prices, the price of pork has also risen a lot. But with soybean meal fermentation technology, Li Zhi can push the price of pork to a lower level than before.

Pork is not available in the market, and a collapse in price will benefit all people.

Li Laosi shook his head and sighed: "Owner, now the people in our territory can eat cheap pork." ”

Li Zhi nodded and said, "Okay, from today onwards, all the pig slaughter prices will be adjusted to twenty-eight yuan a catty." According to the calculation of 70% of the meat yield, the cost of a pound of pork for a butcher is only 40 yuan. The price of pork in the market will be about 45 yuan a catty. ”

"The life of the people will be much better!"

Long Minggui arched his hand and said: "Grandpa Guo loves the people like a son, and the people admire it!" ”

Li Zhi said with a smile: "Long Minggui, you have made meritorious contributions in cultivating mushroom seedlings, and you will be rewarded with one hundred taels of silver, plus a salary!" ”

Long Minggui is now twenty taels a month, and the monthly money is twenty-seven taels with one level. Long Minggui raised his eyebrows with joy, regardless of the smell on the ground, knelt on the ground with a plop, and shouted loudly: "I am willing to saddle the horse and do my best for the grandfather of the country!" ”
