There are hundreds of areas in the farm that are separated by cement masonry and stone.

There are three to four white pigs in each of these areas.

It can't be said that the skin color of these pigs is more inclined to gray-brown, and their last generation is a native Chinese black pig.

It's just that Zhang Qi used to make up a batch of pig breeds from the world of riding and cutting and brought them to the outside world, and after several generations of breeding pigs and local pigs in the world of riding and cutting, today's breed has been formed.

Coupled with the complete castration technology, the pigs in this pig farm are very lazy, each lying in their own area and yawning lazily.

The pig farm here is intensively farmed, with each area separated by a row of hundreds of pens as far as the eye can see, and an aisle between the two rows for employees to clean the pens and feed the pigs.

Thanks to the cement technology of Liaodi and the convenient pipeline technology after the arrival of rubber.

The pig pen drainage system of the pig farm is very well done.

The cement slabs on the aisles are in the form of fences, and the breeding sewage from the pig pens will be directly flushed into the sewers under the aisles, and the sewer systems of the hundreds of aisles in the pig farm will eventually merge into one and flow into the main sewage channel of the Liao groundwater system.

Without the transition to industrialization, Liaodi's sewage was mainly domestic sewage and livestock sewage, which would flow to a barren depression outside the city of Liaoning, where the employees of the fertilizer plant would dry the manure and desalinate the sewage before sending it to the fertilizer factory to make fertilizer.

The big pigs that are about to be slaughtered here are lazy and rarely move every day except for eating.

On the other side, the stall of the young pigs was full of howls.

Zhang Qi and others went to visit with the voice.

Just at a glance, all the men, including Zhang Qi, couldn't help but feel cold in their lower bodies.

The stalls of the young pigs are connected to a hot water pipe, which is much warmer than the stalls on the side of the big pigs.

But even though it was as warm as spring, the flickering cold light made people shudder when they saw the gelding pig for the first time, and the knife flickered and picked out two meatballs from between the two strands of the young pig.

Then the operators threw the meatballs into their waist pockets, wiped the wounds of the young pigs with disinfectant alcohol, and threw them back into the pen without even stitching up the wounds.

The healing power of animals is not comparable to that of humans, and with the skills of these operators, nine out of ten of these young pigs will grow up healthy.

Of course, there are still occasional wounds that need to be sutured, and those who are new to the company will have a full improvement in their needlework before they become journeymen.

Disinfection, hygiene, feed control.

On the farms in Liaodi, there are doctors who check the health of the animals every day.

If the livestock is found to be problematic, it will be dealt with in time and disinfected again, and the breeding industry in Liaodi has developed so far, and these actions and the beast species brought out of the world have hardly occurred.

And some minor illnesses and disasters did not cause any excessive losses.

For the aquaculture industry, Zhang Qi has always adhered to the principle that there are no modern facilities, so it will be filled with several times or dozens of times the labor, and the manpower will be worth it if there is sufficient meat supply.

After seeing two or three pig farms, Zhang Qi visited cattle and sheep breeding, chicken, duck and goose breeding with the acting director of the Animal Husbandry Department one after another.

As for horse breeding, this has always been the top priority in Zhang Qi's heart, so he knew the situation of the horse farm too well, so he didn't visit it.

Nowadays, the horses in Liaodi are almost the best among all the horses in this era, and the bloodline of the popular horse (five generations) has almost improved the bloodline of the horses in Liaodi.

High explosiveness and high stamina, these improved horses have no significant drawbacks.

But this is not all convenient, at least in order to ensure that the war horses in Liaodi do not circulate to the outside, the beast animal power that the people can hold can only be chosen between cattle and giant horses.

In fact, there is no choice.

The amount of food for the giant horse is not something that an ordinary family can raise, so most of the animal power of the people in Liaodi is cultivated cattle that have been trained again.

This time, the director of the Animal Husbandry Department went to the deer herder's camp to obtain a new horse bloodline, and wanted to re-breed a horse suitable for civilian use.

At this point, in fact, Zhang Qi already had an idea in his heart, but he was still busy with the war some time ago, so he never carried it out.

And this time back in Liaodi, the director of the Animal Husbandry Department has already set off, and rashly implementing his own plan will dampen the enthusiasm of these doers, so he plans to wait for the director of the Animal Husbandry Department to return before discussing.

And what he has to discuss, the 'mule'.

Hybrid offspring of horses, donkeys.

A pack beast that has completely lost its ability to reproduce.

It is easy to feed, adapts to any terrain and landform, and is a pack animal that is very suitable for folk use.

Sit in the snowmobile back to Liaoning City.

It was already very dark outside the window.

The frames coming and going along the way are not small even at this time, and at this time, the shift is changing, and the work is off, so there is a lot of traffic on the road.

However, most of these frames are official transportation of a public nature, which is used to facilitate everyone's commuting.

The traffic is a bit heavier though.

But Zhang Qi's left and right are spacious.

These officially recruited drivers recognized Zhang Qi's banner, so no one dared to come to this side.

Drive all the way towards Liaoning City.

As we got closer to the city, there were also some fires on both sides of the road, and people lit the lamps on both sides of the road.

The burning of this mixture of grease illuminates the dimly lit road.

Seeing these lamplighters, Zhang Qi couldn't help but sigh.

It's been ten years.

There is still no progress in the research on edible soybean oil.

The improvements that should have been made have been made, and the pressing process has become more sophisticated, almost comparable to the extraction technology of later generations.

But that smell can't be eliminated.

If the odor of soybean oil cannot be removed, then it can never be eaten, and can only be used as a by-product to support aquaculture, and an industrial by-product exists.

Liaodi is not without the existence of the head iron who insists on cooking with this odorous soybean oil, but without exception, they cannot be eaten for a long time.

The physical techniques that should have been tried, Zhang Qi's team have already tried them, and the results are still the same.

Now, he has almost guessed that after the soybean oil is pressed, some chemical reagents should be added to remove the smell.

But Zhang Qi didn't know what kind of chemical reagent, so he could only wait for the chemical saplings in the Liaodi education system to thrive.

Fortunately, soybean oil is not indispensable to Liaodi, on the contrary, in addition to soybean meal is an excellent feed.

There are many options for oils and fats in Liaodi.

Vegetable oil alone is not just soybean oil.

Peanuts and corn can also be used to extract vegetable oil.
