All the way to the "horses", soon arrived at the pig house in the core area of the breeding farm.

A large part of the facilities in the whole pig house are wooden structures, rather than steel structures that are common in domestic pig farms. This is one of the best solutions for high-density pig feeding in Jiagu Pig Farm - providing a natural and stable living environment, including but not limited to fresh air, constant temperature throughout the year, and a quiet atmosphere......

But after visiting the boar stations of the two units one after another, what impressed everyone the most was not the environment, but the "body shape" of the boars.

"The requirements for breeding boars are high, not to mention anything else, this ......" Fu Dawei, deputy chief engineer of breeding engineering, pointed to his crotch, circled it with his hand, and said: "Have you seen how much it weighs three catties?"

"Really, fake. The man present felt his crotch sink.

For a large breeding farm, breeding boars is very important. In order to avoid the herd gradually becoming offspring of the same boar, it is generally required that the breeding pigs have as much blood as possible.

This breeding farm has the largest breeding boar herd in Jiagu agriculture and animal husbandry, reaching more than 1,500 heads.

Among the adult boars just seen, the diameter of the "eggs" looks to be at least twelve or thirteen centimeters, although it is surprising, it is not unusual. But when converted into quantity, two or three kilograms of eggs, that's really ......

As a man who did not specialize in animal husbandry, he expressed an indescribable ...... In short, it certainly can't be described as a mood of envy. After all, no matter how much a man pursues "toughness", the big crotch is easy to make, and the waist strength is not enough to support a few pounds of balls.

After a few jokes, Fu Dawei introduced the core breeding pig herd of the breeding farm: "The main commercial pig breed of Jiagu pig farm is 'Du Changtai', that is, the first generation of sows crossed between Landrace boars and Taihu sows as the mother, and the ternary hybrid breed with Duroc boars as the father......"

Breeding is really not just talking on paper, but really creating value for enterprises and society. In the final analysis, pig breeding is nothing more than two goals: how to reduce production costs and how to improve the quality of meat.

Jiagu agriculture and animal husbandry aimed at the mass market to improve the "Du Changtai" variety, more around the first goal.

How can I reduce costs?

Let the pigs grow more, let the pigs grow faster, so as to reduce the shared cost and production expenses of the farm.

Solving the problem of more births is reflected in the reproductive performance - total litter size, number of live births, healthy litters, and the number of weaned piglets;

The most ideal breed is, of course, to make pigs grow more, grow faster, and have good meat quality, but unfortunately no pig has all three characteristics at the same time. The method of modern breeding is to allow pig breeds with different characteristics to be crossbred to obtain commercial pigs that combine the three characteristics.

The pork that consumers buy from the market is basically a ternary hybrid pig (ternary is three varieties). This is the reason why ternary pigs are the mainstream of commercial pigs.

Theoretically, the more varieties involved in crossing, the greater the heterosis – the strongest PIC company in the industry uses a quaternary and five-yuan hybrid production system.

The problem is that the more varieties are involved in crossing, the more difficult it is to manage production, and the longer it takes for genetic traits to stabilize.

Therefore, Jiagu has also begun to use the quaternary hybrid breeding system in high-end pig breeding, but ordinary commercial pigs still use the most mainstream ternary crossbreeding.

The original population of Landrace pigs and Duroc pigs introduced by Jiagu has an incomparable style of "big pigs and fast pigs" after continuous breeding, and the local Taihu pig breed is the strongest fecundity in the world, the largest number of litters, and many countries have introduced Taihu pigs to crossbreed with their own pig breeds to improve the fertility of their own pig breeds.

"The PSY of our core sow herd is currently 32 ......"

This time it was Wang Bingwen's turn to ask, it was really fake.

PSY, or the number of piglets weaned in sow years, is one of the core data for measuring reproductive performance.

It is meaningless to compare with the domestic average of 17 heads, only to compare the performance of the pig giants. For large companies like Wen's, PSY is only about 22-26 heads.

When the PSY rises above 30, it is already on par with the legendary Danish pig level.

However, without waiting for questions to be asked, Wang Bingwen came back to his senses: this is completely possible.

As an expert of the National Pig Joint Breeding Cooperative Group, Wang Bingwen still knows in his heart, really to say that the gap between the "Du Changtai" sow herd of Jiagu Agriculture and Animal Husbandry and the sows in the industry in terms of reproductive performance is really so big?

Even in small pig farms, high-yielding sows are not uncommon, but at the same time, they are also facing the problem of "more production and more death".

This involves two meanings of "raising good pigs" - one is raising "good pigs", that is, introducing or breeding good breeds, and the other is "raising good" pigs, achieving the ultimate in various details.

The first point will not be mentioned, and the second point has also been vividly done in the Jiagu pig farm. Pig raising is a science, and science satisfies certain laws, not to make rash decisions at the tip of the brain. Animals have their own physiological characteristics, and there are upper and lower limits for adapting to environmental factors such as temperature and humidity. You won't lose if you're kind to the pigs.

For example, in the "farrowing room" of the sow, Jiagu Pig Farm has set up a special anti-pressure rod to prevent the sow from lying down suddenly, giving the piglets time and space to escape, and the details such as insulation and disinfection of the piglet area are also perfect.

With the high fertility of the "Jia line" pig breed, coupled with the supporting nutrition, on-site careful management, good biosecurity measures, to achieve 32 PSY impressive results, what is so strange?

Wang Bingwen sighed secretly and pulled the on-site management staff to understand various details.

Qi Zheng and the others came for the high reproductive performance of "Du Changtai", and pulled Fu Dawei to the other side and asked in a low voice: "Fu Gong, how much is the stock of the core breeding sow herd now?"

Fu Dawei reacted quickly: "The company plans to speed up the expansion of the breeding scale?"

"Yes. Qi Zheng said frankly: "The speed and time span of the non-plague are not optimistic. Judging from the current situation, the epidemic has not only reduced the number of live pigs, but more seriously, the inventory of grandparents and binary sows has also been seriously damaged. Whether it is to increase the production of Jiagu pig farms during the epidemic or to increase the production of the industry after the epidemic, it is necessary to immediately expand the breeding sow herd. ”

"What is the scale of the increase?"

"Even if you don't count the cooperative units, just Jiagu agriculture and animal husbandry, it is required to form a slaughter scale of 50 million heads next year. ”

The production capacity has more than doubled, and it is by no means an easy requirement for all aspects of pig raising, especially for the pressure of breeding and breeding at the source.

Fu Dawei thought for a while and said slowly: "Before the non-plague strikes, according to normal predictions, next year at the latest, it will be the upward cycle of this round of pig cycle. Because there is a 10-month correspondence between the number of pigs slaughtered and the number of fertile sows, we have planned early and expanded the scale of the fertile sow herd in advance. This breeding farm alone will be able to produce more than 200,000 breeding pigs this year......"

"The company's 'Du Changtai' can breed sows with 1.5312 million heads, well, this will definitely not meet the requirements of 50 million heads slaughtered annually. Fortunately, we still have about 850,000 gilts in stock, and I have two or three months to be able to convert them to fertile sows, and at that point, it should not be a problem to meet the expansion needs of the company and our partners. ”

Qi Zheng looked at Li Dongliang, and he nodded with a smile: "The expansion of the pig farm is going on simultaneously, which is just in time for the gilts to be able to multiply. ”

Fu Dawei reminded: "Now there is another problem, our major pig farms are located in the provinces almost all restrict the inter-provincial transfer of pigs, this problem is not solved, the breeding farm is 'bursting' on the 'burst'." ”

For example, the largest pig farm in China, from the beginning of the design in order to meet the breeding needs of the Jiagu pig farms in Vietnam, Jiangxi and Min provinces, the current inter-provincial transfer of pigs is limited, and it can only meet the needs of one province.

Qi Zheng laughed and said confidently: "I'll solve this problem." Fu Gong, you just need to speed up the breeding work of the core sow herd; Lao Li, you have to coordinate the expansion of the Jiagu pig farm and the synchronous expansion of the cooperative company; Wei Ming, you can help me contact the secretary of Director Hu of the National Development and Reform Commission after I go out......

"Now I'm afraid that there is no 'seed', but with 'seed', in order to ensure the supply of pork, any of our unconventional pig raising initiatives will be strongly supported. ”

In Qi Zheng's arrangement, Jiagu agriculture and animal husbandry's determination to "explode production capacity" by means of non-plague impact has gradually become clear.
