Agricultural giant since 1983

Chapter 151 Better Than Japan

"Commissioner Liu, this is the fish feed that our company has trial-produced, please give me some advice!" Li Lei took out the prepared sample.

"Let me see! Hey, it's still granular. Your company has taken a big step!" Commissioner Liu was a little surprised.

The development history of domestic aquatic feed can be divided into several stages. From the beginning of liberation to [-] years ago, it was mainly natural bait, supplemented by commercial feed.

Breeding units only feed according to the original experience, rely on changes in water color to fertilize, the feed utilization rate is low, and the output per unit area is not high.

The second stage was from 1970 to [-]. It began to use the leftovers of agricultural and sideline products and weeds as raw materials to make mixed feed for feeding. Solve the serious shortage of natural feed for grass carp and herring.

Some good results have been obtained, especially the method of raising fish with grass, which is still applied in many places.

After 1970, it entered the third stage. Aquaculture researchers began to conduct research on feed formula according to the nutritional needs of fish. At this time, they had accumulated the nutritional needs and basic formulas of compound feeds for grass carp, herring, rainbow trout, carp and other fish.

Up to now, pellet feed fish farming has been experimented in some places, but due to the late start, there is still a big gap with aquaculture developed countries such as the United States, Germany, Denmark, Italy, Canada, and Japan.

Today’s feed companies mainly produce poultry feed and pig feed. The aquatic feed industry has not yet started. If it were not for Li Lei, the domestic aquatic feed industrialization would not start until the end of the 80s, ten years later than other feeds. Li Lei is now This time was advanced by five or six years.

The most important thing in making aquatic feed is to analyze the nutritional requirements of fish, and to understand what nutrients different fish need in different growth stages. To figure this out requires long-term observation, research, and experimental analysis.

But Li Lei doesn't need this process. He has in his mind the data on the nutritional requirements of most economic fish species that will be popular in the country in the future, and there is no shortage of feed formula.

The products he brought over this time are quite mature, and according to Commissioner Liu's research field, he has come up with targeted feeds - feeds for grass carp and silver carp breeding stages.

Commissioner Liu crushed the feed pellets with his fingers, put them in his palms to carefully observe the composition of the feed, and even squeezed a little bit into his mouth to taste, "Fish meal, bean cake, rapeseed cake, wheat bran, bone meal, salt Your feed is very targeted!"

"I was also inspired by your thesis. Your previous article clearly analyzed the nutrients needed in the grass carp breeding process. After careful study, we developed this feed formula with some other materials!" Li Lei introduced.

"I used to feed fish with worms, but the protein and fat contained in the worms only accounted for less than [-]%, and the rest was water, and the nutritional composition of various worms was different. Feeding the same kind of worms for a long time would cause It leads to nutritional imbalance and seriously affects the growth and health of fish!"

"Our fish feed is relatively rich in components. Fishmeal can provide protein, fat, and amino acids. Bean cake and rapeseed cake can provide fatty acids and vitamins. Bone meal can provide calcium, not to mention salt. The nutrition is balanced and rich. Almost It can meet all the nutritional needs of fish during growth."

"Fish meal is a good thing! But I see that the thickness of your fish meal is not the same as that of chicken feed or fish feed in Japan. What is the reason for this?" Committee member Liu asked.

"Mastering the quality of corn and other energy feed raw materials is the key to the success of pig feed enterprises, while mastering the quality of animal feed materials such as fish meal is the key to the success of aquatic feed enterprises; so we have made great efforts in this regard. After research, we found that poultry The thickness of fish meal in the feed is between [-] mesh and [-] mesh, which is most conducive to digestion, and it is more suitable to use it in fish feed, between [-] mesh and [-] mesh!"

This statistic sounds simple enough, but it took more than a decade of effort by feed researchers to find the right ratio.

In addition, other ingredients also need attention. For example, among the flour and rice bran in the feed, rice bran is particularly easy to oxidize, so special attention should be paid when using it.

The use of soybean meal, rapeseed meal, and cotton meal in plant protein raw materials often involves issues such as freshness, processing, and doping.

Finally, animal protein is the most important raw material for aquatic feed. Among them, fish meal, meat and bone meal, meat meal, shrimp meal, blood meal, etc. have their own characteristics in quality control. Among the common animal feed raw materials, white fish meal has The difference between cod steak and flounder steak, and the raw materials such as anchovy, sardine, iron turtle and tuna steak in red fish meal are also very different.

To select the right ingredients from so many raw materials, and then mix them together in an appropriate proportion and process them into granules, there are too many things to pay attention to; Then come up with the appropriate feed formula.

Commissioner Liu listened quietly to Li Lei's talk about the uses of different ingredients in the feed. Some of these claims had been thoroughly researched by him, some of which he had explored but hadn't fully figured out, and even a small part of which he hadn't yet understood. Involved.

However, Li Lei’s statement is very reasonable from the perspective of the principle and the nutritional needs of fish. This can’t help but surprise him, because the Aquaculture Institute is already the largest authoritative department for aquaculture fish farming in China, and even they don’t have a grasp of it. How did Li Lei know the knowledge?
"Commissioner Liu, is this gift in line with your wishes?" Professor Xiong saw Commissioner Liu's doubts, because he had a similar experience last year, so he helped explain, "Xiao Li has cooperation with some foreign companies. They got some latest foreign research results."

"Oh, that's it!" Commissioner Liu felt that he understood that developed countries in Europe and the United States have been ahead of China in aquaculture for many years, and it is not surprising that there are achievements that he is not clear about.

The funds of the Institute of Aquatics are much more generous than that of Professor Xiong, but they are not so rich that they can book all the foreign periodicals as much as they want. To order these periodicals, they need foreign exchange. Their annual foreign exchange quota is not much, and they have to buy equipment, so they can only be tight. It is inevitable that there are some omissions in the most critical journals.

"Based on these results, we have done some analysis of the nutrients needed by fish in different growth stages." Li Lei took out a stack of materials and handed them to Committee Member Liu, "Please correct me!"

Putting these materials in Li Lei's hands is definitely not as useful as Committee Liu's ranking. If it can promote the development of the domestic aquaculture field, Li Lei will also be happy.

"You gave me such precious information?" Commissioner Liu was overjoyed. To him, these materials were extremely precious, no worse than Professor Xiong's equipment.

He was also embarrassed to take advantage of Li Lei, so he asked, "Is there anything you need my help for?"

"Yes, as I said just now, I run a feed factory, and I definitely hope that the more fish feed I sell, the better. Our Aquaculture Institute is an authority in domestic aquaculture. If my feed can get your approval , then you don’t have to worry about sales! So I invite you to try my feed.”

"Xiao Li's feed factory is really powerful. I don't know about fish feed, but his piglet feed is definitely this!" Professor Xiong gave a thumbs up, "Since using his feed, the pigs here are getting better every day One day fast, saved me a lot of time!"

"Now the people around here, as long as they raise pigs at home, they have to buy feed from him! The leaders of the city also plan to cooperate with Xiao Li to build a feed factory near here to provide pig feed for farmers in Wuhan! If you are satisfied after using it, can you also ask Xiao Li to add a fish feed production workshop!"

"Haha, even if you don't tell me about this, I'll give it a try! Your feed looks good, and it should be easy to use!" Commissioner Liu originally needed high-quality fish feed, and now it can be said that it hit it off.

"How much is your feed per catty? Give me a ton first, and I'll draw out a few ponds at the fishery station for comparison experiments. If it is confirmed that it is effective, I will sign a long-term supply contract!"

"No money, I will give it to you for free trial. My only request is to arrange a few people to come to your place to monitor the trial effect of the feed at any time!" Previously, He Zhanhai and Lei Yi were sent to Professor Xiong. A few people have studied with Committee Member Liu, and they are all academicians, so we must not treat one more favorably than another.

"If you think it's a good use, you can help us to spread more publicity to those farmers in the future!" Li Lei was worried that Commissioner Liu would be embarrassed, so he quickly added.

"As long as the effect is really good, even if you don't tell me, I will recommend it to those farmers!" Commissioner Liu thought about it, a little feed is really not worth a lot of money, so he didn't continue to worry about this little problem.

Li Lei originally brought a lot of feed samples during his trip, but now he took them directly to the experimental pond of the Institute of Aquatics. Committee member Liu pointed to the pond in front of him and said, "One of the biggest advantages of aquaculture is the high meat production per unit of land. Americans It takes six mu of land to raise a 450-kilogram beef cattle, but with the same area of ​​pond, it can produce [-] kg of fish meat!"

"Our country has a large population and less land. It is too difficult to let go of eating beef like Americans! It is much better to raise fish. Fish is not necessarily inferior to beef in terms of taste and nutritional value! And raising What fish need is water, and the conflict with cultivated land is much smaller than pasture!"

"So the prospects for the development of aquaculture are very bright. You have made the right choice to make fish feed, and there will be great achievements in the next few decades!"

Li Lei wants Commissioner Liu to use his feed, and Commissioner Liu also hopes to develop more supporting enterprises to serve the majority of farmers. After all, no matter how powerful their aquaculture institute is, they cannot take care of every aspect of aquaculture. Also want to have a better feed.

"I am also optimistic about the prospects of aquaculture, so I decided to make fish feed!" Li Lei is more confident in the prospects of aquaculture than Commissioner Liu.

In the future, the annual production of freshwater fish in China will be calculated on the basis of tens of millions of tons. How much feed will be needed to feed fish of tens of millions of tons?This number is definitely not as big as pig feed, but it is definitely not a number that can be ignored. This market has a lot to do.

After chatting for a few words, Commissioner Liu got busy and directed his researchers to draw out several ponds to prepare for comparative experiments.

"The fish in these ponds will be fed with your feed from now on!" After speaking, he pointed to the pond next to him, "These ponds use Japanese feed, and the fish in them are also the best-growing, unfortunately The price of these feeds is too expensive, and foreign exchange is required to import them!"

"We feel a little distressed when we do experiments, and those farmers are even more reluctant to use it! And they have no place to get foreign exchange! As long as your feed is not much worse than the Japanese, I will help you promote it!"

"Japan is surrounded by the sea, and seawater fish farming and fishing technology are very developed. If it is seawater fish feed, I really dare not say that I can beat them right now! But freshwater fish is not the focus of Japanese research. If I even feed them If you can't win, what are you doing?" Li Lei is very confident in his own products.

"Pfft! You really dare to brag!" Before Committee Member Liu said anything, Fang Yu, a researcher at the Fisheries Institute next to him, laughed, "Even though Japan is mainly engaged in seawater farming, they are a developed country after all, and they are so many years ahead of us. , can it be surpassed by just messing around?"

"Is it bragging? Let's try it!" Li Lei was not angry either, because the general environment is like this now, everything is better in foreign countries, even the moon in foreign countries is rounder than China's.

"If your feed is really better than the Japanese's, I'll just jump down and make fish stew for you!" Fang Yu still didn't believe it.

In the next period of time, Li Lei and the college students he transferred from the feed factory worked in the experimental pond of the fishery institute every day. Those college students fed the fish and recorded data with the researchers, and Li Lei seized this rare opportunity. , exchanging information on aquaculture and other aspects with Commissioner Liu.

He quickly found another suitable project. The aerators used in the experimental pond are still imported from abroad, and the price is very expensive. If this can be localized, it will definitely be a good project that can make long-term profits.

After this time's work is over, I will go to Luojing, and strive to set up the agricultural machinery factory as soon as possible. At that time, I can form a team to publicize the aerator project.

It was time for the end of the first phase. Commissioner Liu directed his researchers to take samples, measure body length, weight and other data, and start to analyze the experimental results.

The fish fished from different ponds were put together, and there was an obvious gap. Fang Yu panicked, "Is the label wrong?"

"No, Li Lei's feed is indeed better than the Japanese's!"

Plop, someone fell into the water.
