Mei Yiqi was a little embarrassed and said, "Mr. Zhou, your idea is very good, but the actual operation is a little difficult. Nowadays, during the war, supplies are in short supply, and a large amount of grain is needed to open a chicken farm, and I am afraid that these chickens will be at a loss of cost when raised. ”

Just like raising cattle and horses only needs to feed grass, it is a misunderstanding that many people have about the breeding industry. Raising cattle and horses need to be fed concentrate and coarse material, and raising chickens and ducks also need to be fed with grain, especially before modern feed was not popularized, the consumption of grain was greater.

The problem is that people can't eat enough now, so how can there be food to feed the chickens? Coarse grains are also rushed to eat!

Zhou Hexuan explained: "I mean, let's open a modern scientific chicken farm. ”

In these years, science is very sacred, and everyone is interested in hearing "scientific chickens", and they are busy asking: "What kind of scientific method?" ”

Before Zhou Hexuan crossed, his uncle's family opened a chicken farm, which was not large, and he lost all his money after an avian flu, so he changed to pig farming. Although he didn't know the details very well, he still knew some key points under the influence of his ears and eyes, and explained in combination with the situation at this time: "The first step is industrial incubation; The second step is the identification of males and females; The third step is feed allocation. ”

Fei Xiaotong said: "I know that industrial incubation is available in the UK, and it doesn't seem to be difficult. But what is the identification between male and female, and is there a male and female division of chickens? ”

Zhou Hexuan explained: "First, roosters can't lay eggs, they can only be eaten by broilers; Second, roosters grow fast and strong, and like to grab food, which will affect the growth of other chicks. Therefore, scientific chicken raising must raise hens, and roosters need to be abandoned at birth. ”

Jin Yuelin said with a smile: "The chickens are all the same when they are born, how can they distinguish between male and female?" ”

Zhou Hexuan said: "In ancient times, Chinese farmers could distinguish between male and female chickens, and experienced farmers could easily distinguish male and female by the differences in the appearance of chickens, their voices, bowel movements, and walking. But this observation method is very crude, and the accuracy rate is only seven or eight percent. More directly, you can press and turn open the anus of the chick, the rooster with the bulge, the hen without the protrusion, the accuracy of this method is close to 100%. ”

Zhou Hexuan's method of distinguishing between male and female was widely used by small and medium-sized chicken farms in China in later generations. Despite its seemingly simple appearance, it has changed the recipe of the human table, bringing hundreds of millions of economic benefits every year.

Before the advent of chick identification technology, it was impossible to achieve large-scale farming because the cost of raising chickens was too high. It was not until 1950 that the Japanese Takeo Kisawa invented the chick male and female discriminator, and the chicken industry around the world developed rapidly.

However, the male and female identification technology invented by Takeo Kisawa is very problematic, and it is easy to cause chick infection and death, which is far less safe and effective than the butt breaking recognition that Zhou Hexuan said.

Zhou Hexuan himself is a master of breaking his ass to know his parents, when he was in elementary school, he had to go to his grandmother's house every summer vacation to play. His grandmother and aunt often took him to break the butt of a chick, and he could identify one in a few seconds, which was not much slower than the speed of machine recognition.

With this technology alone, if Zhou Hexuan switches to raising chickens, he will soon become a capitalist and belong to the only chicken raising secret in the world.

Zhu Ziqing exclaimed: "The world is full of knowledge, and I can't imagine that Mingcheng also has in-depth research on raising chickens!" ”

Zhou Hexuan continued: "After identifying the male and female chicks, we must also configure feed. Purely feed rice, beans, and wheat, chickens will not grow well, and the egg production will not be very high, so they need to add a little meat. ”

Mei Yiqi smiled bitterly: "I haven't seen meat for half a year, how can there be meat for chickens." ”

"Meat is not necessarily meat, you can grind bones into powder, and you can also use earthworms," Zhou Hexuan said with a smile, "especially earthworms, which use human and animal manure to fertilize the soil, so that earthworms can reproduce in large numbers in a short period of time." If the chicken farm is large-scale, it is more convenient to cultivate earthworms directly with chicken manure. ”

"That's a good way," Wen Yiduo nodded, "Manure and earthworms are common, and they don't waste food when used to raise chickens." ”

Zhou Hexuan said: "Food is still needed, and if you only feed chickens with earthworms, it will affect the appetite of chickens and lead to a decrease in egg production." ”

Liu Wendian listened to what Zhou Hexuan said, and was surprised: "Mingcheng used to raise chickens? ”

Zhou Hexuan said casually: "When I was a child, I was wandering in the United States and couldn't eat, and I once went to a farm to do child labor. What I just mentioned is the farmer's chicken raising secrets, and I don't teach them to the public. So I only know the approximate, but the detailed feed ratio is not clear. How to use manure to make earthworms reproduce healthily; How to mix and prepare chicken feed to make chickens grow the fastest and best requires repeated trials and tests by teachers and students of the College of Agriculture. ”

This thing really needs students from the College of Agriculture, so that there are fewer detours. Let's talk about breeding earthworms, the College of Agriculture has a soil science department, and they will definitely get twice the result with half the effort.

Mei Yiqi spread her hands and said: "Southwest Associated University does not have an agricultural college. ”

Zhou Hexuan said: "I will go to Chengdu again and invite the teachers and students of the Agricultural College of Central University and Jinling University to come over. Through experiments and explorations, they should be able to develop a set of scientific methods for raising chickens, so as to promote them to the whole country. This chicken farm should not only be opened in the Southwest Associated University, but also in the entire rear of the Anti-Japanese War. As long as it is promoted effectively, it will certainly reduce the price of chicken and eggs and provide nutrition for more poor people. ”

"This is a great thing for the benefit of the country and the people!" Fei Xiaotong, who also majored in political economy with a Ph.D. in sociology at the University of London, immediately anticipated the enormous impact of Mr. Zhou's project.

All of you are smart people, how can you not understand it?

Not to mention anything else, if this scientific method of raising chickens can be successful, at least they will be able to eat eggs every once in a while.

Mei Yiqi immediately made a decision and said: "Mr. Zhou, I will help you choose a piece of land near the school, preferably far away from the city, so as not to be bombed by Japanese planes." I will organize the best architects to design the factory for the chicken farm! ”

Zhou Hexuan joked: "Sicheng and Huiyin are very good, let them design a chicken farm." ”

Mei Yiqi laughed: "That's a little difficult, the couple is inspecting Chuankang." Even if they come back, I'm afraid they won't agree. When I asked Sicheng to design the earthen wall school building, he also lost his temper, saying that Liang Sicheng was not needed to build the earthen house and thatched house. ”

"Haha, I'm just joking, Principal Mei doesn't have to take it seriously." Zhou Hexuan was overjoyed.

Jin Yuelin couldn't wait to raise his hand and said, "I want to participate, I won't grow on the spot, just give me a position as a breeder." ”

"No problem." Zhou Hexuan immediately agreed.

The wild male classmate held the rice bowl and asked excitedly, "Is it possible to see eggs in the cafeteria in the future?" ”

"Of course there are eggs," Zhou Hexuan saw that he was a little familiar, and asked casually, "What's your name?" ”

The wild male classmate said, "My name is Yang Zhenning. ”

Zhou Hexuan: "......"
