Like Professor Liu, Song Yunhui also focused on large-scale projects such as synthesis of ammonia, and pig feed also involved many disciplines such as nutrition and food. The knowledge learned by the Department of Chemical Engineering alone is really not enough.

"Brother Dongbao, I just realized now that it is really difficult to do something in the countryside!" Song Yunhui didn't quite understand. This was obviously a good thing for both parties, so why didn't anyone agree? I guess if it was a large state-owned enterprise to come to find cooperation, they would definitely agree immediately, right?

"Hey, it's because our Xiao Lei family is too small and has no reputation." If you change to Dazhai Village and Huaxi Village come to seek cooperation, it's probably not like this, right?

"But don't worry, we won't eat pigs without Zhang butcher Zhang, so I won't believe it. Without them, this matter cannot be done!" These were already expected by Shen Long. Today's college students are all the prides of heaven, not to mention these university teachers, there are probably not many who can respect village-run enterprises.

"I'll go out, and you'll call all the people in your dormitory later. I'll treat you to a meal!" After that, Chen Long left without waiting for Song Yunhui to agree.

When he came back, he picked up a lot of things, including ham sausages, snacks, Teresa Teng’s tapes, lipsticks, etc., and stuffed a few bags in a mess. He distributed the ham sausages and snacks to Song Yunhui’s roommates Yu Shanqing, Ding Jianguo, and Tian Jiachang, "Thank you for helping to take care of Xiaohui."

"No, no, it's said that although we are a little older than Xiaohui, Xiaohui is the one who helps us with the daily work!" Several people were polite, but in the end they couldn't resist Chen Long. They took it with embarrassment. Yu Shanqing glanced at the remaining ham sausages, snacks, tapes, lipsticks, and what are they going to do?

Chen Long didn't make him curious for a long time. Several people drank a few drinks. After Song Yunhui told him the problem, he revealed the answer, "I just thought about it. This is not that difficult for me. Those teachers are unwilling to help. I asked a few students to help out with a few recipes. It shouldn't be difficult, right?"

"I don't want them to help in vain. These ham and snacks can be taken back to the dormitory to eat by themselves, tapes, lipsticks, etc. can be given to my girlfriend." At this time, colleges do not recommend students to fall in love, but how can there be so many young girls and young men gather together?

"Hey, your method is good! These are hard currency in our school!" Yu Shanqing is a man with many ideas and a quick mind. He immediately understood the benefits of Chen Long doing this. Most of the students nowadays are not very financially good. The things Chen Long brought out are hard currency that are very popular in colleges, and they will definitely attract people to help.

"I know a few food students, I'll ask you!" He immediately offered to help, and Ding Jianguo and Tian Jiachang hurriedly agreed.

In addition, Song Yunhui and four roommates from the 209 dormitory were carrying things and wandering around. When they came back, they lost their things, but there were a few college students behind them.

"I have been exposed to this topic and don't know what kind of pig feed you want? According to the category, it can be divided into full-price feed, concentrated feed and premixed feed; according to the function, it can be divided into piglet feed, sow feed, medium pig feed, etc.; according to the raw materials, it can be divided into bran feed, cake feed, and grain feed..." Zhang Weidong, a senior student who wore eyes like Song Yunhui, first popularized the knowledge of feed learning as soon as he came up, and also explained it specifically to them.

Functional division and raw material division can be understood literally, while full-price ingredients refer to the compound material composed of four parts: protein feed, energy feed, rough feed and additives. It is made into pellets through a machine, and the pig can only eat this.

The concentrate is made of premixed protein raw materials and additives. When feeding, energy materials such as corn and pig grass should be added; the premix is ​​made of a homogeneous mixture made of multiple additives of the same type or different types of additives at a certain ratio. Now some pig farmers know to add some fish meal and other things when raising pigs. This is the most primitive premix.

"Brother Lei, what kind of feed is your village going to make?" Zhang Weidong asked. There are so many types of feed, and if each of them comes out with the recipe, they can't do it.

"According to my idea, it is best to make piglet premix first. The full price of the food costs too much. I am afraid that large state-owned farms cannot afford it, let alone ordinary people." Moreover, this kind of feed occupies too large volume and is not convenient to transport. After it grows, it will also involve large-scale purchases of corn and other grains, which cannot be made at present.

"Concentrated ingredients are convenient, but after you say that, the price is definitely not low, and it is more troublesome to make; premixed ingredients are much cheaper and not difficult to produce. Farmers have used them before and have a higher acceptance. Let's start with this! Let's consider the other two in the future." As for why you choose to make piglet feed, it is even simpler. Piglets are the same every day, and the feed is used quickly, which makes farmers easily accept.

Moreover, farmers nowadays attach great importance to piglets. When they were young, they tried every means to take good care of them, for fear that the piglets would not grow well or get sick, so they would feel much more at ease when they grew up. They might not be willing to ask them to buy pig feed for big pigs, but they would be much more willing to buy it for pigs.

"I have studied this topic. Generally speaking, the feed formulas required for one to ten kilograms of piglets are: 60% corn, 10.5% wheat bran, 15% peanut cake (bean cake), 10% domestic fish meal, 3% yeast powder, 1% bone meal, and 0.5% salt. This formula contains 3101 kcal of digestive energy per kilogram, 18% crude protein, 2.9% crude fiber, 0.7% calcium, 0.62% phosphorus, 0.79% lysine, and 0.7% egg + cystine. 5 grams of copper sulfate, ferrous sulfate, furoxillin, 10 grams each of multivilinear." Zhang Weidong breathed a sigh of relief after hearing this. It was not difficult.

"But we also have to consider the grain production situation in Jinling County and the preferences of local farmers to feed pigs. We don't produce corn, and few farmers are willing to use corn to feed pigs. In addition, I think there are a few chemical raw materials you just mentioned, and I'm wondering how difficult it is to find." It's not enough to just have theory, you have to combine it with reality.

"Brother Lei, what you said makes sense. Tell me about the situation in Jinling County. I will think about it with a few classmates." Zhang Weidong pushed his glasses and said, "These tapes, lipsticks and so on are really not easy to take.
