Li Zhi stood at the pig farm outside Fanjiazhuang City, looking at the fermented dregs produced by Long Minggui, the person in charge of the pig farm, and nodded.
Li Laosi stood behind Li Zhi, looked at the paste-like substance, and asked curiously: "Boss, can fermented soybean meal be fed to pigs? I have never heard of it. In the past, soybean meal was obtained from soybean oil refining.
They are all thrown away, they are poisonous and pigs will die of illness if they eat too much."
Li Zhi nodded and said: "This fermented soybean meal is a treasure. The dragon is precious. You can feed it to us!"
Long Minggui was stunned for a moment and said: "The Duke of Guo has a body worth thousands of dollars! The pig house is dirty, I'm afraid it's not the place where the Duke and the general officers should go!"
Li Laosi said: "Long Minggui, I fed pigs for several years when I was a child!"
Li Zhi waved his hand and said, "No problem, let's go to the pig house and you can find some pigs to feed us!"
Long Minggui sang "Hey", then asked someone to pick up a bucket of fermented soybean meal, and took Li Zhi and others into the pig pen. Li Zhi took a look inside the pig house and found that it was not particularly dirty. Li Zhi was building the pig house at the time.
When raising pigs, we repeatedly emphasized the need to pay attention to hygiene. Each pigsty has a special area for pigs to excrete, and drainage ditches are built in the pigsty. Pig workers carry water to clean the pigsty twice a day. So the entire pigsty
Although the pig farm smells bad, it's still bearable.
There are pigs of different ages in different areas of the pig farm. Various signs are hung on the pig pens with various parameters of the pigs written on them, which looks quite organized.
It was feeding time, and the breeders were pushing carts of pig food into the pig pen. Long Minggui found a circle of fat pigs and poured the bucket of dregs into the trough.
As soon as the glutinous fermented soybean meal was poured in, the ten fat pigs in the pig pen rushed over and gathered around the pig trough to eat. Obviously, for the pigs, the glutinous rice was very sweet, even more delicious than sweet potatoes.
.It only took half a minute for ten pigs to finish 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 showed it to Li Zhi. He handed it to Li Zhi and said, "Mr. Guo Gong, we sorted and cultured the 'fermented bacteria' according to the method you said. It took three years.
Finally, we found the most suitable 'bacteria'. Previous fermentation bacteria could not eliminate the toxins in soybean meal, and the pigs would get sick and have diarrhea after eating it. But with fermentation bacteria, it is completely different, and it can turn toxic soybean meal into sweet taste.
pig feed.”
Long Minggui was a little cautious when he spoke. The fact that Jin Guogong knew everything made Long Minggui in awe of Li Zhi. People all said that Jin Guogong descended from the stars, and Long Minggui created fermentation bacteria according to Professor Li Zhi's method.
After Miao, I feel that this statement is probably true.
The Duke of Jin turned stone into gold and turned useless soybean meal into treasure.
"Soybean meal" is the residue left after soybean oil extraction. This residue is rich in various nutrients, with a crude protein content of about 45%, and is rich in other nutrients, such as about 1.5% fat, about 12.5%
It contains carbohydrates, various minerals, vitamins and essential amino acids in the animal body. It is especially rich in lysine, which is easily lacking in other plant-based feeds, and its content is as high as about 2.6%.
However, soybean meal contains trypsin inhibitors, soybean antigens and other anti-nutritional factors. Due to the presence of these "toxins", not only do animals fail to utilize the nutrients in soybean meal, but eating large amounts can endanger the lives of animals.
Therefore, in the Ming Dynasty, all the refined soybean meal was discarded. At most, it was buried in the ground as green manure, and no one used it to feed animals. As a kind of waste after oil refining, the price of soybean meal is almost free.
There is a huge business opportunity buried here.
To remove these toxins in soybean meal and turn waste into treasure, the best way is fermentation. In the 21st century before Li Zhi traveled through time, toxic soybean meal was the most important pig feed, precisely because of the existence of fermentation technology.
Through the fermentation of fermentation bacteria, the toxins in soybean meal can be greatly eliminated.
Not only that, the fermentation process can also increase the content of active peptides, amino acids and other beneficial substances, increase probiotics, and make nutritious soybean meal the sweetest pig feed.
Soybean meal fermentation technology can be said to be a landmark technology in the pig industry. As a time traveler, Li Zhi will naturally not let this technology go.
The main source of edible oil in Ming Dynasty is soybean oil extraction, and the amount of "useless" soybean meal produced every month is very huge. Finding this fermentation bacteria can turn useless and valuable soybean meal into treasure, which can greatly reduce the cost of Li plant growth.
The cost of raising pigs.
Of course, the cultivation of fermentation bacteria is not accomplished overnight. Li Zhi taught Long Minggui the method of sorting and cultivating fermentation bacteria for future generations. Long Minggui spent three years and poisoned dozens of pigs before he got the
Qualified vaccines.
It can be said that this kind of mushroom cake is more precious than gold. If outsiders steal this kind of mushroom cake, they can immediately make a fortune.
Li Zhi looked around at the mushroom cake and handed it to Li Laosi.
Li Laosi looked at the mushroom cake from side to side, shook his head and said, "This is really magical!"
Li Zhi looked at Long Minggui and asked: "What is the feed-to-meat ratio of fermented soybean meal?"
Long Minggui cupped his hands and replied: "We now use 60% fermented soybean meal, 30% sweet potatoes and 10% pigweed to feed pen pigs. After excluding the pigs that died of disease, the approximate feed-to-meat ratio is five to one."
Li Zhi nodded.
Long Minggui added: "We contacted the oil refining workshop in Beizhili and purchased soybean meal, which is the oil refining waste, on a large scale. We can buy a large amount of soybean meal at the price of two cents per kilogram. Including freight, the cost of transporting soybean meal to the pig farm is no more than
It costs three and a half cents per catty. Calculating this, the feed cost for one catty of pork is only sixteen cents."
"Even if the oil refinery 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."
"Including other labor costs, our pig cost can also be controlled at 23 cents per catty. The current price of meat on the market is more than 70 cents per catty. Once the pigs we raise with soybean meal are put on the market, the price of pork will go through a period of decline.
The market plummeted!”
With the increase in grain prices in recent years, the price of pork has also increased a lot. But with soybean meal fermentation technology, Li Zhi can bring the price of pork to a lower level than before.
There is no stock of pork in the market, and the plummeting price will benefit all people.
Li Laosi shook his head and sighed: "Master, now all the people in our territory can eat cheap pork."
Li Zhi nodded and said: "Okay, starting from today, we will adjust the pig slaughter price to 28 cents per catty. Calculated based on the meat production rate of 70%, the butcher's cost of one catty of pork is only 40 cents. In that market
The price of pork sold on the website is about forty-five cents per catty."
"The lives of the common people will be much easier again!"
Long Minggui raised his hands and said: "The Duke of the country loves the people like his own son, and the people admire him!"
Li Zhi smiled and said: "Long Minggui, for your merit in cultivating the vaccine, I will reward you with a hundred taels of silver, plus a first-level salary!"
Long Minggui's current monthly income is twenty-seven taels, and if you add one level of monthly income, it will be twenty-seven taels. Long Minggui was overjoyed, and regardless of the stench on the ground, he knelt on the ground with a plop and shouted: "I am willing to ride for the Duke of the country.
