Through the rain curtain, Guan Fei could dimly see the newly built board houses in the valley.

This valley is relatively deep, about 300 meters wide, but more than a kilometer deep, and it is a very secluded and good place.

Not far from the valley is a long, spired-top bungalow, where the logistics platoon and the guards lived, as well as forty hired locals.

Guan Fei didn't want to put too many soldiers here, after all, they were all young people with junior high school and high school education, and it was too wasteful to just use them for logistics and breeding.

However, the scale of the farm he built is not very large, but the ultimate goal is to build a super-large-scale intensive modern farm. In the future, it will reach the scale of hundreds of thousands of chickens and tens of thousands of pigs, and become the main supplier of meat products in the city.

Scientific breeding is different from farmer free-range breeding, which is in accordance with industrial standards, all have strict scientific basis, with standardized procedures to operate the scientific breeding base, with higher technical content. Ordinary farmers do not understand the reason, free and loose, it is likely not to strictly abide by the operation process, which will not only cause a reduction in breeding efficiency, but also more likely to cause serious losses due to wrong operations, such as poor sanitary environment and incomplete disinfection procedures.

The warriors, on the other hand, were disciplined and listened to orders.

In addition, Guan Fei himself has no practical work experience in this area, so he just copied out the key points of intensive breeding technology and green recycling farms and handed them over to the farm cadres so that they can digest and absorb them in practice. This requires a certain level of knowledge, and without the young soldiers to act as agricultural technicians, it is not possible to rely solely on the farmers invited by the local area.

There are doors in front of and behind this dormitory, and you can hear the sound of sawing wood from the outside. Guan Fei walked over and pushed open the front door, only to find that it was busy inside.

Although it was raining, the soldiers did not rest.

"Brigadier Commander!" A soldier inadvertently turned his head and found Guan Fei standing in the doorway with a smile on his face, and immediately shouted.

The voices disappeared suddenly.

The soldiers stopped what they were doing and looked in the direction of the door, and sure enough, they saw Guan Fei's tall figure standing in front of them.

"Brigadier Commander, why are you here?"

"It's raining heavily outside, Brigadier Commander, what ...... you are"

"Whoever has dry clothes, hurry up and get a set for the brigade commander!" The soldiers all rushed over, gossiping to express their surprise and concern for Guan Fei's unexpected arrival.

Warriors are not fools, nor are they puppets without thoughts, they have their own views of good and evil and judgment of things, and whoever is good to them, even if they don't say it with their mouths, they know it in their hearts. Since the establishment of the 291st Brigade, everyone knows how much Guan Fei has done for this brigade and for everyone.

Seeing that Guan Fei worked tirelessly, with so many important tasks to be busy every day, and still came to visit everyone in the rain, everyone's heart felt warm. Even the hired locals, although they did not gather around, watched from afar with eager eyes.

"Company commander, put it on, you're soaking wet! This little comrade, you also change into dry clothes, don't catch a cold. Song Tao, the person in charge of the feedlot and the platoon leader of the logistics company, quickly took out a set of military uniforms from his bed and handed it to Guan Fei.

Another soldier next to him also handed his dry clothes to the guard Xiao Li. The driver parked the car and walked in, but he was in the car all the time, and it didn't rain, so he came in with a small piece of wet on his shoulder, just wipe his face with a towel.

Song Tao's body width is similar to Guan Fei's, but he is a little shorter, and 1.72 meters is also tall for southerners in this era, but it is much shorter than Guan Fei's 1.85 meters.

There were no clothes suitable for Guan Fei among the soldiers here, so they had to use his generals.

Guan Fei took off his wet clothes, and his own fighters immediately took them over and washed them again and dried them. Changing into dry clothes, not only him, but also the soldiers around laughed.

The sleeves are about 10 centimeters from the wrist, and the trousers are obviously shorter, just like wearing a child's clothes.

"Brigade commander, this dress fits well, but the hand tube and trouser tube are too short, as if they have shrunk. You're wearing it here, and if you wear it back, you'll probably laugh when you see it. Song Tao leaned forward and leaned back, pointed at Guan Fei and smiled.

"Okay, you Song Tao, dare to laugh at me? Who made you only 1.72 meters! Don't say that I'm short, but blame me for being long, how can this be reasonable! Guan Fei feigned anger.

Song Tao was scolded by him, but he was not afraid at all, but he was happy in his heart.

As soon as Guan Fei opened his mouth, he said his real height, indicating that he really cared about the cadres and soldiers below. Only with them in their hearts will they shout each other's names, each other's family situation, and past experiences without any obstacles.

Having such a brigade commander is a blessing for thousands of cadres and fighters of their 291 Brigade!

Guan Fei greeted every soldier around him with a smile, and everyone said a few words, calling out each other's names, and then commenting on the recent changes in work and life. Those who have done well are praised and encouraged, and those who encounter setbacks are concerned about whether their difficulties have been resolved, whether they need help from the troops, and whether their knots have been opened.

Although everyone could only say a sentence or two, each warrior was contented, smiled from ear to ear, and was reluctant to walk away around him.

After Guan Fei had a brief conversation with the cadres and soldiers, he talked with the hired masses for a while.

These honest local people were very shocked to find that although Guan Fei had never known them in his life, as long as he introduced himself, he could immediately shake hands and talk to him in a targeted manner.

"Uncle Bolt, it's okay at home. Your son Haidong has been hired and is now assigned to the 13th engineering team, responsible for the leveling work of the University of Electronic Science and Technology of China. You can rest assured, the troops will take him well, their captain is Comrade Chen Heping of the second platoon of the third company of the engineering battalion, this is an old comrade, he is serious in his work, he will definitely bring Haidong out and become a real construction worker in the future! ”

"Brother Gongba, it's only nineteen, and he's already so tall! Is your mother feeling better? Well, go back and carry your mother to the health center to see, the elderly have a bad stomach, and you can't be careless about minor illnesses......"

……

Dozens of people, one by one, were all exchanged by him as if they were chattering, and everyone was surprised that the brigade commander knew so much about himself and his family's situation, but also felt the same great admiration - can he remember so many things, is that what ordinary people can do?

After Guan Fei greeted everyone, he asked everyone to continue working, and then found a place next to Song Tao and other cadres to understand the work situation.

"Brigade commander, I'll take you over and see it directly, and the scene said that you know more about it." Song Tao said that he found a few umbrellas and prepared to take Guan Fei to the field to see, talking while watching.

"That's better!" Guan Fei happily agreed.

He rejected Song Tao's idea of helping him hold an umbrella, and he didn't want Xiao Li to help, so he took an umbrella and walked out of the house to open it.

Song Tao took him to see the fly maggot breeding house first.

According to the information provided by Guan Fei, it was built during his visit to Hong Kong. At that time, the troops lacked food and clothing, and these wooden houses were built by the soldiers with axes and axes, and then sawed into planks one by one, which took more than a month to build.

The construction of the temporary school that had just started was different, with the carpentry equipment he brought back, the wood was sent back, and the use was determined according to the thickness, and it could be directly cut into sections with a table saw, and then divided into wooden boards.

When Guan Fei came out, this work had already been demonstrated, and a truckload of wood arrived, and it turned into regular planks and sticks in more than an hour. Then, under the guidance of Meng Nan and other field engineering teams, the teacher's office was already under construction.

At this rate, it is expected that the teacher's office will be set up in the evening.

This is the charm of the industrial age, even if manual work is half tired and half dead, it is not as good as the output of industrial mass production in a day.

However, the farm and temporary school building are made of new wood and have not been dehydrated and dried. Now, in order to rush and build a building with these new woods, there will definitely be a problem of shrinkage and deformation in the future, and only then will it be repaired.

The maggot breeding house is located near the river, and a path has been opened against the mountain wall, and it has been more than ten meters into another small depression.

This is also in accordance with Guan Fei's instructions, the fly maggot breeding house was built here.

Because of the strong smell of fly maggots, if they are placed in the valley, they will smoke all people, birds, and animals feel uncomfortable, so they can only find a separate ventilated place to raise them.

The house is also a steeple wooden house, and in order to protect it from rain, the roof is also covered with a layer of linoleum, and a layer of asbestos is built to prevent spontaneous combustion in summer heat. The surface layer of asbestos is brushed with asphalt, which is to prevent the asbestos silk wool from detaching and getting uncomfortable on people.

The wooden house is fully enclosed, and on both sides of the house are two layers of cages placed on top and bottom. The cage frame is made of wooden sticks, with a piece of iron sheet at the top and plastic nets at the front, back, right, and bottom. There are also four feet at the bottom end, which makes there a certain gap between the upper and lower layers.

This is the adult fly cage that is used to feed adult flies that have grown wings.

Fly eggs are collected twice a day, and the feedlot is to mix a large disk with ammonia carbonate and wheat bran to make a mixture of about 60% water, and place it at the bottom of the adult fly cage, close to the plastic net.

Attracted by the smell, the fly will actively extend its tail end out of the grid and lay its eggs in the egg collection tray.

Further on, on both sides are small pools made of cement.

Due to the lack of materials and the lack of cement before, this pool was only evenly brought from the cement they brought after Meng Nan and the others came, and it was just two days after it was built.

The pool is not large, only 1.5 meters, and 40 centimeters high.

In order to prevent maggots from crawling out, it is also covered with a net. At the same time, a hole was made in one side, and a piece of gauze was sewn as a feeding operation.

After the eggs are collected, they are placed in the maggot pond and hatch in just eight hours.

The reproduction rate of flies is amazing, each female fly can ovulate 100 to 200, when the temperature is 25 to 30 degrees Celsius, it can hatch in eight hours, mature and start to pupate in four days, and break out of the cocoon and feather in three days and become an adult fly.

Guan Fei explained that this kind of fly maggot breeding house, two maggot ponds can produce ten kilograms per day.

Whether it is maggot breeding or earthworm breeding, both of these are using the high content of protein contained in their bodies as animal protein intake for poultry and livestock, and not all of them are used as feed. Its proportion is only between 4 and 10 percent of the total feed.

For example, cage chickens in the feedlot, each chicken consumes an average of 90 grams of feed per day, so the content of fresh maggots and earthworms only accounts for a few hundred grams.

Ten kilograms of maggots is enough for more than 2,000 chickens.

In addition to animal protein, chickens also need to eat energy foods such as corn, minerals such as calcium, phosphorus and potassium, vitamins, etc. To help the chickens digest, a sand tray is also placed for them to peck at themselves.

So it doesn't mean that there is no cost to feed chickens with earthworms and maggots.

In order to raise fodder, the 291st Brigade is exchanging rice for corn kernels from the common people, and when it comes back, it will be ground into corn flour, and then it will be mixed with other auxiliary materials, mixed with chopped green cabbage leaves, and then mixed with maggots scalded to death with boiling water into it, which is the final feed.

There is not enough food source, what maggots feed the chickens, that's!

It is just a large number of human beings eat meat, poultry and eggs, the saved food, transferred to poultry and livestock to eat, converted into meat products, egg products, to achieve the balance of human nutrition intake, not to say that with these two means of feeding, it is omnipotent, and there is no need for other feed costs.

The cost is the same, if not higher!

If Guan Fei didn't have enough financial resources, he would not be willing to spend money in order to keep the educated youth, and he wouldn't be able to afford a large-scale breeding farm at all! It can only be like ordinary farmers, either free-range or small-scale breeding, and the growth period and meat content of poultry and livestock are definitely not high.

The significance of earthworm breeding and fly maggot breeding is that its nutritional value is high, and the growth period of poultry and livestock mixed with these feeds is accelerated, and the meat production and egg production are increased, and the egg laying period of laying hens is extended.

For example, the growth period of domestic chickens is generally 180 days, and eating this feed can shorten the growth period of 10 to 20 days, enhance the ability to resist diseases, gain 20 to 30 percent of the weight of broilers, and extend the laying period of dozens of days for laying hens.

This is where the real economic value of maggot breeding lies!

The shortened growth period will result in a faster output cycle; Enhancing resistance can reduce the mortality rate of poultry and livestock and reduce the cost of treatment; Not to mention weight gain, an increase in unit output; Extending the laying period is equivalent to extending the service life of the production line and increasing the rate of return.

This is like the three-inch wafer production technology, compared with the six-inch wafer production technology, this is its scientific and technological content!

For farmers who have mastered the technology of fly maggot breeding, have large-scale centralized scientific breeding experience, and have sufficient funds, these benefits are all money, of course, it is more cost-effective than using general feed feeding!

Those farmers who do not know how to raise earthworms and fly maggots will have a much lower output ratio than farmers who have mastered this technology at the same cost. Even if they understand the benefits, they can only buy the finished product from others because they can't raise it themselves, which is just as expensive.

What Guan Fei did was only to put himself one step ahead in technology - whether it was the electronics industry or livestock breeding!
