Chapter 1279 Let's Do It Ourselves
Song Yunhui, like Professor Liu, also puts the main energy on large-scale projects such as synthetic ammonia, and pig feed also involves nutrition, food science and other disciplines, and the knowledge learned by the Department of Chemical Engineering is really not enough.
"Brother Dongbao, I just realized now that it's really difficult to do something in the countryside!" Song Yunhui didn't understand. This is obviously a good thing for both parties, so why didn't anyone agree? It is estimated that if a large state-owned enterprise came to seek cooperation, they would definitely agree immediately, right?
"Hey, our Xiaolei family is too small, and there is no reason for its reputation." If you were to seek cooperation from Dazhai Village or Huaxi Village, it probably wouldn't be like this, would it?
"But don't worry, we don't eat hairy pigs without Butcher Zhang. I don't believe it. Without them, this matter can't be done!" These things have long been expected by Shen Long, and now College students are the pride of heaven, not to mention these university teachers, there are probably very few who can look up to village-run enterprises.
"I'll go out for a while. After a while, you will call everyone in your dormitory, and I will treat you to a meal!" Shen Long left without waiting for Song Yunhui to agree.
When he came back, he carried a lot of things, including ham sausages, snacks, Teresa Teng's tapes, lipsticks, etc., stuffed a few bags in a mess, and he distributed the ham sausages and snacks to Song Yunhui's roommate Yu Shanqing, Ding Jianguo and Tian Jiachang, "Thank you for helping take care of Xiaohui."
"No, no, no, speaking of it, although we are a bit older than Xiaohui, it is Xiaohui who helps us with homework!" Several people continued to be polite, but in the end they couldn't hold back Shen Long. Accepting it with embarrassment, Yu Shanqing glanced at the remaining ham sausage, snacks, and those tapes and lipsticks. What are they going to do?
Shen Long didn't keep him curious for long, a few people drank a few glasses, and after Song Yunhui told the problems he encountered, he revealed the answer, "I just thought about it, this is not a difficult subject for me, those The teacher doesn't want to help, so I'll ask a few students to help me make some recipes, it shouldn't be difficult, right?"
"I won't let them help for nothing. These ham sausages and snacks can be taken back to the dormitory to eat by myself, and tapes and lipsticks can be given to my girlfriend." At this time, universities do not recommend students to fall in love, but so many young people How can the big girl and the young man not talk about it when they get together?
"Hey, you have a good idea! These are hard currency in our school!" Yu Shanqing has many ideas and a quick mind, and he immediately understood the benefits of Shen Long's doing this. Most of the current students are not in good financial conditions. These things that Long brought out are extremely popular hard currency in the university, and they will definitely attract people to come to help.
"I know a few food science students, I'll help you ask!" He immediately offered to help, and Ding Jianguo and Tian Jiachang also quickly agreed.
In addition to Song Yunhui, the four roommates in the 209 dormitory walked around with their things together. When they came back, their things were gone, but there were a few more college students behind them.
"I have been exposed to this subject, but I 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, etc. Pig feed, medium pig feed, etc.; according to the raw materials, it can be divided into bran-based feed, cake-based feed, grain-based feed..." Zhang Weidong, a senior student who wears eyes like Song Yunhui, popularized it as soon as he came up Some feed science knowledge, but also specifically explained to them.
The functional division and raw material division can be understood from the literal meaning, while the full-price feed refers to the compound material composed of four parts: protein feed, energy feed, roughage and additives. It is made into granules by machine, and pigs can only eat this.
Concentrated feed is made of premixed protein raw materials and additives. Energy feeds such as corn and pigweed need to be added when feeding; the premixed feed is made of multiple additives of the same type or different types of additives according to a certain ratio. The homogeneous mixture formed, now some veteran pig farmers know to add some fishmeal and the like when raising pigs, which is considered the most primitive premix.
"Brother Lei, what kind of feed does your village plan to make?" Zhang Weidong asked. There are so many types of feed, if they come up with the formula for each of them, they will not be able to do it.
"According to my opinion, it is best to make premixed feed for piglets first. The full-price feed costs too much money, and I am afraid that even large state-owned farms can't afford it, let alone ordinary people." The volume is too large, and the transportation is inconvenient. When it becomes bigger, it will involve the large-scale purchase of corn and other grains, which is impossible right now.
"Concentrate is convenient, but from what you said, the price is definitely not low, and it is more troublesome to make; premix is much cheaper, and it is not difficult to produce. Farmers have used it before, and it is more acceptable. , let’s start with this first! We’ll consider the other two in the future.” As for why we choose to make feed for piglets, it’s even simpler. Piglets have different feeds every day, and the feed can be used for quick results, which is easy for farmers to accept.
Moreover, farmers now attach great importance to piglets. When they were young, they tried to take good care of them. They were afraid that the piglets would not grow well or get sick. When they grow up, they will be more at ease. They may not be willing to ask them to buy pig feed for big pigs. , but I would rather buy it for Xiaozhu.
"I have studied this topic. Generally speaking, the feed formula required for piglets weighing 1 to 10 kilograms is: 60% corn, 10.5% wheat bran, 15% peanut cake (bean cake), 10% domestic fish meal, 3% yeast powder, Bone meal 1%, salt 0.5%. This formula contains 3101 kcal of digestible energy per kilogram, 18% of crude protein, 2.9% of crude fiber, 0.7% of calcium, 0.62% of phosphorus, 0.79% of lysine, 0.7% of egg + cystine Add 5 grams of copper sulfate, 10 grams each of ferrous sulfate, nitrofurazone, oxytetracycline, and multivitamin to every 100 kilograms of the mixture." Zhang Weidong was relieved after hearing this, and this is not difficult.
"However, we must also consider the grain production situation in Jinling County and the preferences of local farmers for feeding pigs. We do not produce corn there, and few farmers are willing to use corn to feed pigs; in addition, the chemical raw materials you mentioned just now , I’m thinking about some of them, and I’m afraid it’s hard to find.” Theory alone is not enough, you have to combine reality.
"Brother Lei, what you said makes sense. Tell me about the situation in Jinling County. I will discuss it with a few classmates." Zhang Weidong pushed his glasses, and I just said, these tapes, lipsticks and so on are really not good take it.
