Before the cartoon finished, it was time for dinner.
The children were allowed to watch it for a while longer. After watching this episode, they were happy. Although it was only five minutes, they were happy.
Li Yi and Li Longji stared at the food in a daze. They were not hungry, but they drank too much beer.
The prime minister and the others ate happily. Each of them only ate half of what they had eaten at noon.
They took a bite of each of the many dishes to maintain a balanced nutrition.
Nanqu's' big shots' also controlled their food to maintain their figures.
Princess Yongmu had a large plate of braised pork in front of her. "Xiao Lan, let's eat until we're 70% full at noon. We'll make up for it at night."
"Okay, let's not eat so many quail eggs, okay? We'll each have two. "
Xiao Lan was worried when she saw ten quail eggs on the plate.
Li Longji, Li Yi, and Li Chengqi continued to drink beer. Li Yi took six quail eggs from Princess Yongmu's plate.
Princess Yongmu chose braised pork and braised eggs. Fat and protein were both nutritious.
"For dinner tonight, I suggest that we don't ask Xiao Yi anything about economics, politics, military affairs, or people's livelihood."
Bi Goo might feel embarrassed to ask Li Yi so many questions every time he met him.
Everyone nodded. Okay, let's not ask those questions. Let's chat.
"Xiao Yi, it seems that you bought a lot of quail eggs in Zhuangzi. The people picked them up from the grass and sent them to you?" Bi Goo chose a casual topic.
"How many quail eggs can you pick up?" Li Yi gave Li Longji and Li Chengqi two quail eggs each.
"Quails are small. Why raise them?" Bi Goo asked.
"Raise them to lay eggs. This is already the ninth batch. Choose those that lay more eggs and incubate them."
Li Yi took a sip of beer and threw a quail egg into his mouth.
"Xiao Yi, you're wrong. It's better to raise chickens than to raise quails. Quails can fly, but eggs can't. Eggs are big, but quail eggs are small. It's not worth it."
Bi Goo gave his opinion according to Egg's novel.
Li Yi filled his glass with wine. "It usually takes seventeen days for a quail egg to hatch, while it takes twenty-one to twenty-three days for a chicken to hatch.
Quails lay eggs in less than 40 days, and chickens needed at least four months.
In the later stage of selection, the quail's egg production could exceed 260 eggs a year. If the chickens were not fed in a centralized manner, it would be considered good if they could lay an egg every two days.
A chicken egg weighed about five quail eggs. A newly laid chicken weighed seven or eight times more than a quail. It would grow bigger and bigger in the future.
The bigger they grow, the more food they eat. The overall weight ratio of the eggs they lay is far less than that of quails. "
Li Yi gave a bunch of data and came to a conclusion. Taking into account the incubation and laying cycle of quails, as well as the number of eggs and the ratio of food, it was more cost-effective than raising chickens.
Unless they used intensive breeding and fed antibiotics to the chickens, they would not be able to catch up with quails.
"So, in the future, we can raise quails for the common people?" Bi Goo was interested.
"Yes, we will produce a few more batches of quails and try to increase the number of eggs produced. Otherwise, we will have to fatten them up and sell them for meat in about a year." Li Yi admitted that he already had a plan.
Bi Goo nodded. "Quail eggs and quails are not as convenient to eat as chicken and eggs. How do we eat them?"
"The most suitable way to cook quail eggs is to boil and braise them. As for quails, we can braise them in soy sauce, stew them in soup, or barbecue them.
Quails are bigger than sparrows. Even sparrows can eat quails, let alone quails.
After dinner, you can go to the place where Zhuangzi raises quails. The north needs to warm the roads in winter, and the south is most suitable. Otherwise, it will affect the egg production. "
Li Yi explained patiently.
Bi Goo smiled. "Xiao Yi, you really think about the common people. In the time it takes to eat, you …"
As he spoke, he paused. Everyone was looking at him with a different gaze.
"Hmm!" Lu Huaishen coughed. "Just now, someone suggested that we should not talk about politics with Xiao Yi during dinner."
Everyone nodded. Yes, someone said that before.
"It's not me. Why are you looking at me? I only mentioned quail eggs. Xiao Yi said it herself. Who knew that when I mentioned quail eggs, everyone … "
Bi Goo felt wronged. I was just looking for a topic to talk about. Aiya, there are so many dishes. Why did I choose quail eggs?
It seems that it is best not to talk when eating with Xiao Yi.
"It's okay. We can talk about anything." Li Longji tried to smooth things over. He also did not expect that quail eggs would be related to the common people's livelihood.
So, everyone started talking about the song and dance. Li Yi did not continue to talk about it. During the day, he had talked about what to do when the children grew up.
After dinner, everyone formed a group and went to see the quails.
After walking for a long time, they arrived at their destination.
There were houses and cages here. The cages were made of bamboo and looked like fences. There was also a fenced shed on top of the cages. The quails stayed inside.
There was a big circle of cages with a lamp. The quails' eyes reflected the light. They were more active. They mainly ran around and drank water and ate food.
When they saw people coming, the quails immediately squeezed into the corner. Some of them went around the drinking area to hide. They did not drink enough water.
When more lamps shone on the cages, the situation in the cages became clearer.
The quails hid far away. They could see the quail eggs on the ground. There were patterns on them.
"Why is there a bamboo jar on top of the water basin?" Liu Chong noticed the situation.
"Don't worry about it. There is still food in another open jar.
When the quails drink water to a certain extent, the water level will be lower than the mouth of the jar. The water in the jar will flow out. When the water flows out and seals the mouth of the jar, the water will not flow out.
The other jar is higher. When the quails eat the food, the food will fall out. There will be a pile of food and they will stop eating.
It is a very simple automatic feeding device. If it is not handled this way, the quails will jump into the water basin and food basin and dirty the food and water. "
Li Yi introduced two small tools. In his opinion, they did not require much skill.
Wei Zhigu approached and squatted down to observe carefully. "I know the feeding device, but why doesn't the water flow out?"
Li Yi was surprised. The craftsmen of the Tang dynasty were very skilled. As the Minister of Works, how could you not know?
"I know, I know. It is the air pressure. The air pressure is holding back the water." The little girl jumped out. She knew because she had learned it from her master.
"Air pressure?" Several people pondered this term.
"It is the power of our breathing. I will go get something. I need a glass cup and a piece of hard paper." The little girl wanted to do an experiment for everyone.
"I have it." Qing Song, who was pulling the box, took the initiative to speak.
He opened the box and took out the cup and paper. It was the paper Li Yi used to draw.
The little girl used her hand to fold and cut the paper. It was square, and the length from the center to the edge was larger than the diameter of the mouth of the cup.
She added water to the cup. Seeing that the water level was higher than the mouth of the cup, she covered the cup with the paper. After a while, she carefully covered the paper and turned the cup upside down.
She slowly let go of the paper. The paper was stuck there, and the water in the cup did not fall.
"Look, this is the air pressure. The force of the air pressure is greater than the gravity of the water in the cup. The water is suppressed by the air pressure."
She was very satisfied with her operation. She had a sweet smile on her face as she succeeded in making it on her first try.
Everyone was curious, but Li Yi was indifferent. She could even make the Water Armillary Sphere. How could a small water feeder be a problem?
