When she arrived at the pig farm, Su Yan found that the pig farm here was different from the ones she had seen in the countryside in her previous life.
The pig houses in the pig farm are all made of stone. Each pig house is the same size and is neatly arranged in rows like tofu grids.
The pigsty was very clean, and even the water in the trough was crystal clear. Su Yan had thought that since drinking water was difficult for people nowadays, they would go to the river to pick up yellow water for the pigs.
"Captain Zhang, are you feeding the pigs well water?"
"No, it's spring water. Isn't there a big mountain over there? There's a cave with spring water on the mountain. We used bamboo baskets to bring the spring water down. People can drink it, and pigs can drink it too."
Well, the pigs on this farm live better than people in other places. The geographical environment is good, with mountains behind it and a big river nearby. It is simply a paradise on earth.
No wonder their troops were able to donate food and vegetables to disaster victims in other places.
Su Yan first went to see a few litters of piglets and asked curiously, "Captain Zhang, why are there only seven or eight pigs in each litter?"
"Old sows only give birth to so many puppies. One sow originally gave birth to nine puppies, but one of them suffocated to death during birth."
"I'm saying that the litter size of your sows is a bit low. Some good sows can give birth to fifteen or sixteen piglets per litter, and the largest can give birth to more than twenty piglets."
Zhang Minghao opened his mouth wide and looked at Su Yan in disbelief. "Comrade Su Yan, you are not kidding, are you?"
"I'm not kidding. Foreign sows can indeed give birth to more than ten or twenty piglets per litter. This is why our country imported white pigs from the Soviet Union.
I heard the Academy of Agricultural Sciences has quite a few white pigs. If we want to increase sow production, we'd better borrow their white pigs for hybridization..."
Lu Fengnian looked at his daughter-in-law Su Yan with a smile. She wanted to borrow someone else's chicken to lay eggs in her own nest.
"Captain Zhang, I think this proposal is feasible. The farms of the Academy of Agricultural Sciences have also imported Soviet white pigs for several years. We can indeed borrow their pigs for breeding and hybridization.
If that doesn't work, we can also buy a few small white pigs from them to keep as breeding stock."
Zhang Haoming thought for a moment and said, "I think we'd better send someone to the farm of the Agricultural Science Academy to investigate and see if they have bred any hybrid pigs.
Comrade Su, the report says that white pigs can be slaughtered in four to five months. If this is true, it will indeed solve the problem of people having difficulty getting meat."
As expected of the company commander of the pig-raising company, his brain is more flexible than that of ordinary people.
"Captain Zhang is right. You should send someone to the Agricultural Science Academy's pig farm first. Maybe they can find a way to import other white pigs from other countries."
Because she knew that most of the white pigs raised by the people later were introduced from Denmark and the United Kingdom, one was the Danish Landrace pig and the other was the British Yorkshire pig.
"Let's hold a meeting first and then decide who to send to conduct the research. We need to think of a way to increase sow births."
Su Yan walked to a pig house and saw a boar lying on the sow's back for mating. She paused awkwardly.
Company Commander Zhang was no longer surprised by this. He smiled and said, "Comrade Su, I just told you that the three sows are in estrus, so we drove the boars over to breed them."
Su Yan hummed awkwardly. Lu Fengnian was only concerned about when the sow in estrus would get pregnant. If she did, she would have new piglets next year.
After all, Lu Jin was a young man and had never seen such a scene before. He was so embarrassed that his face turned red.
Soon the boar suddenly stopped moving. Su Yan discovered that there was something wrong with the boar's breeding, but she couldn't tell her father-in-law and brother-in-law because she was around.
Because there was not enough time to feed them, Su Yan naturally didn't know what these black-skinned pigs ate.
People are not able to eat enough nowadays. I wonder what the pigs in their army eat.
"Captain Zhang, may I ask what you feed these pigs? With so many pigs, they must use a lot of pig feed every day!"
"We have people who go to the river to collect grass for the pigs, and then mix it with rice bran leftover from milling and cook it for the pigs."
"Do pregnant sows eat this way? I think if you want your piglets to be big, you can add some fish meal and shrimp meal to supplement their nutrition."
People need supplements when they are pregnant. Pregnant sows can be given nutritional supplements by mixing shrimp meal and fish meal into their feed.
Anyway, Jinshi is not far from them, so it should not be difficult to buy some shrimp meal and fish meal.
After a stroll around the pig farm, Lu Fengnian took Lu Jin to see his friends, and Su Yan followed Captain Zhang with her notebook.
She was now going to explain to them how to raise pigs scientifically. Of course, she first expressed her appreciation for the soldiers in the pig-raising company. She had never seen such a clean pig house in all these years.
This group of soldiers is really different. With them around, pigs live more comfortably than humans.
Then, from the perspective of large-scale farming, she discussed the selection and breeding of breeding pigs, the use of hybridization, the feeding and management of pigs at different stages, and the biosafety measures of pig farms...
Pollution-free pig production technology and prevention and control of common diseases among pigs in pig farms.
Even the vaccination techniques and medication guidelines for pig farms, as well as various injection methods combined with clinical practice are briefly described.
This lecture lasted the entire morning. To be honest, she had no experience in pig farming. She was just standing on the shoulders of giants and reading from the book.
Su Yan was speaking eloquently at the top, while the soldiers below were taking notes seriously in their little notebooks.
Someone asked, "Comrade Su, how do you know so much? Is there large-scale pig farming in your hometown?"
"My grandfather's hometown also raises pigs, but they only have about 20 or so. We don't have a large-scale pig farm in our village."
"Then where do you get all this experience?"
"A small part of it was taught to me by my grandfather, and most of it was taught in books."
"What book? A book about pig farming? Can you lend it to us?"
Su Yan thought about it and decided that some books with contents like modern pig farming technology could not be borrowed. If she removed the others, she could tear off the covers and lend them to them to read so that they could make progress together.
"Okay, I'll go back and look for it and send it to you guys."
Before leaving, Su Yan called Captain Zhang aside and said, "Captain Zhang, I noticed something was wrong with your boar's breeding. Do you have to breed the pigs several times before the sows can get pregnant?"
"Yes, what's wrong?"
"The boar has dropped its seed, so we have to mate more often."
Zhang Haoming didn't realize what seed she was talking about at first, but then he slapped his head and realized he was talking about boar semen. Married women are really different; they dare to say anything.
"Well, Comrade Su, do you have any good ideas?"
"Artificial insemination of sows to improve their pregnancy rate."
"Artificially inseminating sows?" Company Commander Zhang looked at Su Yan in astonishment. "You're not asking us men to inseminate sows in heat, are you?"
“Puff!”
