The farm has two pairs of Landrace pigs and a pair of Northeast folk pigs as the initial breeding pigs. To expand the herd, Kao's own exotic females are not enough - it is too much waste of valuable semen from the boars. A sow can only give birth to two litters a year, while a boar can breed 20~30 sows a year, and nearly 1,000 sows can be bred a year by artificial insemination.

Therefore, he deliberately collected the most representative local pig Lingao pig as the female parent, and used artificial insemination to rapidly expand the population. The local pig industry is quite developed, and every farmer raises pigs, but unfortunately the level of feeding is too poor, and according to the standards of modern animal husbandry, all are malnourished, and Yang Guigui barely bought a dozen or so passable sows to breed. In addition, more than 10 female pigs were carefully selected and raised, ready to be used as breeding mothers.

Because Xiong Buyou talks all day long about protecting purebred Lingao pigs - every time he talks about the crossbreeding of purebred Lingao pigs at the Lingao Animal Husbandry Station, Xiong Buyou is always filled with righteous indignation. Yang Guigui specially brought a few rack pigs from farmers for fattening and breeding, and found that Lingao pig is not a pig breed suitable for large-scale production in modern agriculture - its growth period is too long, and the slow weight gain is unheard of. He asked the locals to find out that it takes 24 months to fatten a pig of about 200 catties before it can be slaughtered. Compared to modern pig herds, which are only a year, it is really uneconomical.

"It is understandable that the Lingao Animal Husbandry Bureau turned the Lingao pigs into a hybrid breed, otherwise how could it satisfy such a large number of exports?"

"You're also making Lingao pigs a crossbreed now."

"I still have a few purebreds - I have to keep a few breeding animals for each breed. It is important to keep the original species. ”

Most of the newly built rows of pigsty on the farm are still empty. Lingao is not very cold in winter, but the summer is more humid and hot, there is a lot of rain, and there is a typhoon problem, so Yang Guigui chose a single-slope open pigsty when presiding over the construction of the farm, which is conducive to ventilation and heat dissipation. Moreover, the materials used in the pigsty are quite exquisite, and the ground is all smoothed with cement. The whole pigsty strives to be strong, able to withstand strong winds, and has good rainproof performance.

"Summer typhoons are no joke," Yang said, "and now they are cheap, and the pigsty collapses and crushes the pigs." ”

Wu Nanhai noticed that there was a large area of land enclosed by a sturdy bamboo fence near the pigsty, the soil had been turned upside down, and there were several black mud ponds.

"This is a stadium for pigs," said Yang, "although they don't have running pigs, they can increase their appetite when they exercise in moderation, and the mud pond is also a favorite sport for them to play - it can also prevent diseases." ”

Many plants have been planted around the barn and the playground, including windbreak saplings, pumpkins at the base of the walls of the barn, and zucchini on the top of the barn. It can not only shade and cool the pigsty, but also be used to supplement feed.

"This pig's life is really free. The surrounding environmental hygiene is also good. ”

"Of course, animals also have psychological pressure, and you don't think pigs like dirty and smelly environments. They have a good life, so that they can get less sick, grow faster, and have good meat. Breeding pigs can be full of spring. ”

"You see, this is a purebred Lingao pig." Yang Guigui pointed to the dozen or so weaned piglets sleeping in the pigsty, "The taste of Lingao pig is really good, especially the roast suckling pig," Yang Guigui smacked his mouth, "So raise some separately and let Xiong Buyou make roast suckling pig for you to eat." ”

Strict rearing in pens is practiced here. Yang Guigui told Wu Nanhai that there are as many as 9 kinds of pig houses here that adapt to different states and ages. Each type of pigsty has different sizes due to the different number of heads raised, and the equipment structure is also slightly different. In addition to this, there is a special breeding room for breeding and a farrowing house for sows.

"The so-called scientific pig breeding does not necessarily have to have full feed, antibiotics, disinfectants and vaccines - this is a helpless move under the modern commercial mass production. With limited conditions like ours, there are many simple and effective jishu that can be used, and the same haode effect can be achieved - that is, it is worse in terms of breeding scale and efficiency. But it's definitely eco-friendly. ”

"Let's just say that this pigletter." Yang Guigui asked him to see the floor of the pig house, which was a one-meter-high iron grid floor erected with stone piers.

"This kind of jishu is called 'online breeding' - the feces and urine of the pigs will leak down, and will be absorbed by the bedding on the ground, and the pigs will be clean and dry, and the pigs will not be easy to get dysentery. The survival rate is much higher. It's a very simple principle, and it's not difficult to implement. ”

"It's kind of like 'raising chickens on a high bed.'"

"Yes, this jishu is actually connected." "There are also automatic drinking fountains. Last time I went to the Workers' Energy Committee to ask them to do it, these people didn't have to say that there was no plastic rubber, in fact, what kind of plastic and rubber do they want, just use a lever switch, and it doesn't matter if you leak a little water. However, the use of automatic drinking fountains not only improves the drinking water of pigs, but also benefits the environmental hygiene of the pigsty. The pigs are less sick and don't need to be given antibiotics all day long......"

Except for a small number of parts that are metal, all the soil water dispensers made by the Machinery Factory of the Industrial Energy Commission are ceramic and bamboo. The water flows from a high-raised reinforced concrete tank with thick bamboo pipes. As long as the pig arches a bamboo lever, the water will flow out of the ceramic jar that stores the water and flow into the drinking tray below. This device has some water seepage, but it is cleaner and less wasteful than pouring water into a stone trough.

"Another example is the feeding of feed. Here is still the traditional 'thin soup full feeding' feeding method, pig food is rare, feeding is full, it looks like saving material, in fact, too much water affects the digestion of pigs, but it is not easy to fat. As for pig food, cooked feeding is not necessary, not only the nutritional value is damaged, but also easy to cause nitrite poisoning. Labor and fuel. In addition to swill, general feed can be fed raw. A lot can be done with this small improvement of the soil method. ”

Yang Guigui is now focusing on expanding the breeding of pigs in Northeast China. In addition to the use of Northeast folk pigs as hybrid mothers in modern society, they have basically stopped doing pig breeding, because its fat deposition rate is too high, and it belongs to pigs that love to grow fat, and the demand for pigs in modern society is to grow as much lean meat as possible: in addition to lean pigs, there are also so-called "running pigs", and the simplest is clenbuterol and the like. So this pig is not welcome. But for the Crossing Group, pigs are not only responsible for providing meat, but also for the supply of fat, an industrial resource.

Outside of pigs, cattle are the largest herd in feedlots. Hainan's main export products historically include cattle. There are many local buffaloes and cattle in Lingao. The Loi district is also a major supplier of local cattle. More than 100 cattle were continuously transported from Lingoli District Trade and Changhua Fort, which made the scale of the cattle farm expand a lot.

Cattle in cattle farms are mainly used as animal power. At present, it is not used much for field labour, mainly for the transport of goods - ox cart transport is now becoming the main mode of land transport through the group. Yang Guigui not only has to engage in breeding and rapidly expand the herd, but also has to take into account the needs of animal power. Speeding up the import of cattle from Changhua is only the most haode choice, and after a little recuperation and rest can be put into service, cattle have low requirements for feed, and there are no concerns about feed supply.

He screened the cattle transported from all over the place, and the buffalo meat was coarse and old, mainly used for animal power to pull carts, so he controlled the scale of buffalo breeding, and mainly raised various cattle. Cattle can not only be used to pull carts, but also for both meat and leather.

The cattle in the cattle farm are resting at this time, it is now afternoon, the weather is hot, and several agricultural workers are sprinkling water around the cattle shed to cool down. These cattle are very well cared for because they have to bear the heavy task of road transportation every day, not only adding concentrate every day, but also ensuring that they are given adequate rest.

"There are a lot of cattle," Mr. Wu said, "but it seems that beef is becoming more popular." ”

"Actually, the ideal breed for us is cattle and sheep – just eat grass. Pigs want a lot of grain. Green fodder can only be used as a supplement. The habit of raising pigs here is to eat rice when fattening, which is too wasteful. ”

"Large-scale cultivation of sweet potatoes is to ensure fodder food. In fact, cows also have to eat grain. Eat corn or something. ”

"Traditional cattle farming is simply grass-fed cattle. It is also possible to feed special green fodder. Corn cattle breeding can only be done in a country like the United States where natural conditions are too superior. Yang Guigui sighed, he has a soft spot for North America.

They walked through the barn where the breeding bulls were specially breded, and the fences were very thick, and the bulls were short-tempered, large in size and strength, and had to be careful both in feeding and serving. However, the local breeding bull poplar is not very valuable, and only a few are raised for the purpose of maintaining the original breed. The local cows that are now pregnant are all the frozen sperm of several high-quality breeds of cattle brought from modern time and space for different purposes.

Breeding cows are mated in the spring. Pregnant cows are kept in separate rooms, and a sign is hung in front of each pen with the number of the cow, the age of the cow, the date of conception, the expected date of birth, and the breed and breed.

Seeing Yang Guigui coming, several cows stuck their heads out, and a pair of big gentle and moist eyes stared at him, and mooed.

"You see they all know me." Yang Guigui jokingly stroked the neck of one of the cows, "This one is expensive, it is pregnant with a black and white cow." The milk of the future will count on its children. As he spoke, he checked the trough to see how the cattle were feeding, and then checked the blackboard hanging on the wall to see if the keeper had accurately recorded the feeding status. Yang Guigui has very strict control over feed feeding, and all forage, concentrate and salt are regularly quantified.
