Chapter 1279: Let's do it ourselves

Like Professor Liu, Song Yunhui also put his main focus on large-scale projects such as synthetic ammonia, and pig feed also involves many disciplines such as nutrition and food science. It is really not enough to learn that knowledge by the Department of Chemical Engineering.
"Brother Dongbao, I realized now that it's really difficult to do something in the countryside!" Song Yunhui didn't quite understand it. This is obviously a good thing for both parties. Why didn't anyone agree? It is estimated that if they are replaced by large state-owned enterprises to find cooperation, they will definitely agree immediately?
"Hey, our small Lei family's scale is too small, there is no reason for fame." If you switch to Dazhai Village and Huaxi Village to seek cooperation, it is estimated that it will not be like this?
"But don't worry about it. Without Zhang Tufu, we don't eat pigs with hair. I don't believe it. Without a few of them, this can't be done!" These have long been expected by Shen Long. Today's College students are the arrogants of the heavens, not to mention these university teachers, and few village-run enterprises can be expected.
"I'm going out, and after a while you call all the people in your dormitory, I invite you to have a meal!" After Song Yunhui agreed, Shen Long left.
When he came back, he mentioned a lot of things, such as ham sausages and dim sums, as well as Teresa Teng ’s tapes, lipsticks, etc., and stuffed up a few bags. He distributed the ham sausages and dim sums to Song Yunhui ’s roommate Yu Shanqing, Ding Jianguo and Tian Jiachang, "Thank you for helping Xiaohui."
"No, don't use it. Although we are a little bigger than Xiaohui, we usually help Xiaohui with our homework!" Accepted embarrassingly, Yu Shanqing glanced at the remaining ham sausage, snacks, and those tapes and lipsticks, what are they going to do?
Shen Long did not make him curious for a long time. After a few people had a few drinks, when Song Yunhui said the problems he encountered, he revealed the mystery. "I was thinking about it. I am not a difficult subject. Those The teacher is not willing to help. I asked some students to help me get a few formulas out, should n’t it be difficult? "
"I wouldn't let them help. These ham sausages and snacks can be taken back to the dormitory and eaten by myself. Tapes and lipsticks can be given to my girlfriend." At this time, the university does not recommend students to fall in love, but so many young people How can the elder girl and the young man get together?
"Hey, you are good! These are hard currencies in our school!" Yu Shanqing, who has many ideas and active mind, understood the benefits of Shen Long's doing so. Most of the current students are not in good economic conditions, Shen. These things that Long took out are hard currency that is very popular in college, and it will definitely attract people to help.
"I know a few food science students, I will help you to ask!" He immediately offered to help, Ding Jianguo and Tian Jiachang quickly agreed.
Coupled with Song Yunhui, the four roommates in the 209 dormitory took things around and wandered around. When they came back, the things in their hands were gone, but there were a few more college students behind them.
"I have touched on this subject, 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 premix; according to the function, it can be divided into piglet feed and mother. Pig feed, pig feed, etc .; according to the raw materials, it can be divided into bran feed, cake feed, grain feed ... "Zhang Weidong, a senior student who wears his eyes like Song Yunhui, first popularized Some knowledge of feed science was also explained to them.
The function division and raw material division can be understood literally, while the full-price material refers to the compound material composed of four parts of protein feed, energy feed, roughage and additives, which are made into granules by the machine, and the pigs only need to eat this.
Concentrated materials are made by premixing protein raw materials and additives, and corn, hogweed and other energy materials need to be added when feeding; the premix is ​​made of multiple additives of the same type or different types of additives according to a certain ratio The homogenous mixture is now some pig veterans who know that adding some fish meal and other things when raising pigs is the most original premix.
"Brother Lei, what kind of feed do you plan to make in your village?" Zhang Weidong asked. There are so many types of feed, and if each one comes with a formula, they can't make it.
"According to my ideas, it is best to make premixes for piglets first. The full price of the material costs too much. I am afraid that large state-owned farms cannot afford it, let alone ordinary people." And this kind of feed accounts for The size is too large, and transportation is not convenient. After it is enlarged, it will involve large-scale acquisition of corn and other grains, which cannot be done right now.
"Concentrated materials are convenient, but listening to you, the price is certainly not low, and it is more troublesome to make; the premix is ​​much cheaper, it is not difficult to produce, and the farmers have used it before, and the acceptance is higher. Let ’s start with this one! Let ’s consider the other two in the future.
As for why we choose to make piglet feed, it ’s even simpler. Piglets are used every day. The effect of using feed is quick and easy for farmers to accept.
Moreover, the current farmers 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 become ill. When they grow up, they can rest assured that they may not be willing to buy pig feed for the piglets. , But it would be more desirable to buy a piggy.
"I have studied this subject ~ EbookFREE.me ~ Generally speaking, the feed formula required for piglets of one to ten kilograms is: corn 60%, wheat bran 10.5%, peanut cake (bean cake) 15%, domestic fish meal 10% , Yeast powder 3%, bone meal 1%, table salt 0.5%. This formula contains 3101 kcal of digestive energy per kg, crude protein 18%, crude fiber 2.9%, calcium 0.7%, phosphorus 0.62%, lysine 0.79, egg + Cysteine ​​0.7%. 5 grams of copper sulfate, ferrous sulfate, nitrofurazone, oxytetracycline, and multivitamin each 10 grams per 100 kilograms of mixture. "Zhang Weidong breathed a sigh of relief after hearing this. what.
"But we still have to take into account our food production situation in Jinling County and the preference of local farmers for feeding pigs. We do n’t produce corn there, and few farmers are willing to use corn to feed pigs; in addition, you just said those chemical raw materials I am thinking about a few things that might be hard to find. "You can't do theory alone, you have to combine it with reality.
"Brother Lei, what you said makes sense. You talk about your situation in Jinling County. I will discuss it with a few classmates." Zhang Weidong pushed his glasses, so I said, these tapes and lipsticks are not good. Take it.
