Two minutes later, the system gave the simulation results again.

[Best result: 70% meat leaf hogweed, 10% protein feed, 20% energy feed, after 10 months, the weight of the sample is 119 kg, and the taste is reduced by 10%]

Chen Cheng touched his chin.

He believes that the supercomputer's simulation is correct and should have the greatest effect on the production of Iasi black pigs by simply changing the feed ratio.

In the same 10 months, from 94 catties of 100% meat leaf hogweed, to 119 catties now, the weight growth rate of Iasi black pigs has reached 26%.

This number is not simple.

Although this small increase is really not enough to put the farmers in the mountains of Iasi on the road to becoming rich by raising pigs, it can at least help improve their lives.

Let's put it this way, at least they can eat a few more catties of pork.

Chen Cheng felt that he could accept this effect without using the super "weapon" of his genetic combination.

He returned his attention to the ratio of feed.

From the original 100% feeding of meat leaf hogweed, to the current ratio of 70% meat leaf hogweed, 10% protein feed, and 20% energy feed, he is afraid that farmers in the mountainous areas will not be able to accept it.

In particular, it is necessary to pay for feed.

Protein feed includes two categories: plant-based protein feed and animal-based protein feed. Plant-based protein feeds include legumes and their processing by-products, cereal processing by-products and oil cakes.

The representatives of plant-based protein feed are: soybeans, broad beans, adzuki beans, and oil cakes left after extracting oil from the seeds of oil crops, as well as vinegar grains, distiller's grains, powder residues, tofu pools, sauce residues and so on left over from milling, grain production and winemaking.

The crude protein content of plant-based protein feed is abundant, accounting for about 20-40%, the content of starch and sugar is lower than that of cereals, and the content of vitamins and minerals is close to that of gramineous grains.

Animal protein feed includes blood bone meal, fish meal, silkworm pupa, etc., which is characterized by high protein content, which is 3-8 times that of grain feed, and is fed together with energy feed in feeding, and the appropriate use can make male and female sows reproduce normally, promote piglet growth and fattening weight gain.

Animal-based protein feeds are often a high-end nutritional supplement, just like milk powder. It is for female spiders, piglets and breeding pigs who are in dire need of nutrition.

Pigs that grow normally are generally not fed.

Plant-based protein feeds were also used in the system simulation.

This is followed by 20% energy feed.

Energy feeds include cereal energy feeds and bran energy feeds.

Cereal energy feeds include corn, rice, barley, millet, sorghum, buckwheat, barnyard seeds, etc. It contains more than 70% starch, about 10% crude protein, 3% crude fat and crude ash, and about 14% moisture.

Low crude fiber, good palatability, and high digestibility. The crude protein content is low, the essential amino acid content of the pig body is very small, the mineral is poor, and the types and contents of vitamins are mostly less.

Bran energy feeds include wheat bran, sorghum bran, barnyard bran, etc. Its crude protein content is higher than that of cereals, generally 10%-16%. Vitamin E is abundant, and there are more B vitamins than grains, so rational use helps to balance the nutrition of the diet.

Both protein feed and energy feed are well understood.

Protein provides high protein nutrition for pigs, and energy feed contains a lot of starch, mainly providing energy for pigs.

Chen Cheng guessed that beans, oil cakes, dregs and other things are common raw materials for feeding pigs, and farmers in the mountainous areas of Iasi should have them, but they do not have a scientific matching ratio, and the feeding effect is not so obvious.

Now there is also the question of why the taste of Iasi black pig decreases after each experiment.

"The First Evolution"

Even if you are fed 100% Iasi porgy, it will also reduce the taste.

Although the taste of Iasi black pig is about 40% better than that of ordinary Landrace pigs, Chen Cheng felt extremely uncomfortable when he thought that such a delicious pork reduced the taste.

In scientific research, he has obsessive-compulsive disorder.

After repeatedly checking the formula of the experimental feed, Chen Cheng discharged the problem with the feed.

"Simulate the growth process of Iasi black pigs at high altitudes of about 4,000 meters." Chen Cheng said.

The supercomputer was still very efficient, and it was answered a minute later.

"Huh?" Chen Cheng buckled his head suspiciously.

There is still an 8% decrease in taste.

In this way, altitude is not a factor that affects the taste of Iasi's black pig.

It can only be analyzed by contrast.

Chen Cheng took out the pork with a reduced taste that had just been experimented with, and compared it with the original Iasi black pork for chemical analysis.

Finding the differences between them may lead to the problem.

[Original Iasi black pig contains 32% fat, 63% protein, 4% meat amino acids, creatine liver, sugar, inorganic salts and iron, copper, zinc, manganese, cobalt, selenium and other trace elements 1%]

[Simulated cultivation of Iasi black pig contains 32% fat, 65% protein, 2.7% meat amino acids, creatine liver, sugar, inorganic salts and trace elements such as iron, copper, zinc, manganese, cobalt, selenium and 0.3%]

"That is, the difference is in the various trace elements and amino acids."

When Chen Cheng was chattering, he immediately reacted to something he hadn't noticed just now.

Drinking water during the breeding process of Iasi black pigs.

In addition to the food you eat, water is also the most important ingestion substance.

The water simulated by the supercomputer cultivation is ordinary pure water, while in the real cultivation, the Iasi black pig drinks the mineral water of the plateau!

That's where the biggest difference lies.

Chen Cheng tried to input a mineral water into the supercomputer and simulate it again.

[In the case of 70% meat leaf hogweed, 10% protein feed, and 20% energy feed, the sample weighs 121 kg after 10 months, and the taste is reduced by 2%]

"That's right!" Chen Cheng smiled.

Not only did the taste hardly decrease, but it also increased the weight by 2 catties.

This is only the result of a simulation using a mineral water, and Chen Cheng speculates that it might be even better if it were replaced with high-altitude spring water that is unique to the Iasi Mountains.

It's a pity that he didn't use the system to scan the information of the mountain spring water in the mountains of Iasi, and now he can't match the trace element content of this water for a while.

However, now that all the problems have finally been clarified, Chen Cheng feels that he can accept this result.

So he exited the system, took out the phone and called Lao Xu.

"Lao Xu, have you slept?" Chen Cheng asked.

After all, it's already 11 o'clock.

Lao Xu's complaining voice came: "Lao Chen, I was just woken up by you when I fell asleep." In the future, if it's not such a thing as sending a wife, can you call during the day? ”

Chen Cheng said embarrassedly: "I didn't send you a wife, I sent you a feed formula for Iasi black pigs." ”

Lao Xu was excited, and his voice was much clearer: "What formula, you say." ”

"Do you remember? Why don't I send you a text message? Chen Cheng asked.

"No, I've already taken out a small notebook, I can write it down."

It can be seen that Lao Xu is really interested in the cultivation of Iasi's black pig.

Chen Cheng told Lao Xu the recipe again, and told him to be sure to feed it with mineral water.

Lao Xu was a little embarrassed: "The feed is easy to get, after all, there are many breeding centers." But mineral water...

Lao Chen, you know, the school is so poor, where can you use mineral water to feed the pigs. We are usually fed with tap water. ”

Chen Cheng thought for a while and said, "You don't have to worry about this, tomorrow I will ask Principal Zhao to approve a little mineral water for your breeding center, which will be specially used to breed Iasi black pigs." ”

"Really? It has to be your old Chen who has face. Lao Xu hung up the phone excitedly.

Chen Cheng thought about it, if Principal Zhao knew that he had started to engage in animal husbandry technology again, he would definitely agree to his request very readily.
