Wang You can't find any words to describe the shock in his heart, this is simply a miracle, only one acre of land can raise 5,000 chickens, if this is not a miracle, there will be no miracle under the sky.

"No......!"

Wang You immediately realized a problem that he had overlooked, what about feed? Doesn't it take a lot of feed to raise so many chickens? Where does this feed come from, and sheep and cattle and horses need to be fodder, can so much livestock be fed in a small valley? And what about the people in the valley? It's not okay if you don't eat or drink, do you all drink the northwest wind to live?

"Da Lang...... It seems that raising livestock requires a lot of feed, can it be supplied in the valley? And it's winter, where to find feed for cattle and sheep? ”

"That's a good question!" Zhen Qian nodded approvingly, "You are very smart and very good at finding out the problem, there are 20,000 chickens, 10,000 ducks, 3,000 sheep, 1,000 pigs, 500 cattle and 100 horses in the entire valley, so many livestock is not enough to turn the entire valley into pasture, there is not so much feed in the valley at all, what if it is you?" ”

This question is a bit difficult, Wang You racked his brains and couldn't come up with the right answer, "There is really no way, you can only transport feed from outside the valley, but Da Lang just said that the valley should be self-sufficient, so there is no way!" ”

"I just said that I am self-sufficient in food, but I didn't say that we should also be self-sufficient in feed......

Wang You found out that he was tricked by Zhen Qian, what is this called self-sufficiency, what is it that is not transported, can you transport feed but not grain?

"I don't understand!"

Of course, Wang You can't understand, "Why can you transport feed but not grain, is there a difference between the two?" ”

"Of course there is a difference, and the difference is very big", Zhen Qian said patiently: "Think about it, if one day the grain outside the valley cannot be transported in, or in order to prevent the outside world from discovering this valley, do you say there is a difference?" ”

It seems to make some sense, Wang You understands what Zhen Qian means, since it is a paradise, he doesn't want people to find out, it doesn't matter if there are no chickens, ducks, cattle and sheep in the valley, but once the food is cut off, it will be over, and Wang You still understands that the valley is Zhen Qian's lifeblood.

But Wang You still has a question: "Da Lang, just now mentioned winter feed, I'm afraid this is not a problem that transportation can solve?" ”

"You asked very well, winter is the difficult period for cattle and sheep to raise, even the nomads can not solve the problem of winter cattle and sheep feed for the winter, but you don't forget the wisdom of the working people, there is nothing that can't be done, only the way to think of it, autumn is the fat period of cattle and sheep, why? Because the grass is abundant in autumn, is there a way to preserve the grass until the winter? ”

Wang You's eyes lit up and then darkened, "This is impossible, everything in the world grows according to its own operating laws, and the grass in autumn is not bad in winter, even if it is not bad, there is no nutrition?" ”

"I'm still too narrow-minded, follow me!" , Zhen Qian patted Wang You on the shoulder, Wang You is very smart, he has accompanied him for eight years, and he can master the Four Books and Five Classics and arithmetic without any teacher, if he is not a slave, it is not much of a problem to take a show, which is also the reason why he attaches importance to Wang You.

The two walked downstairs to the door, "Uncle Wang, open the cellar!" ”

Wang Lun stretched out his hand to lift an iron plate on the open space, Wang You smelled a strong smell of grass coming from the underground shop, with the torch in Wang Lun's hand, Wang You saw that the cellar was full of pasture, and the grass was neatly packed into a pile, although it didn't look very fresh, but it could be inferred from the taste that the grass should be edible.

"As long as you find a way to store pasture, that is, to solve the problem of livestock losing fat in winter, if you add some grains, livestock will not only not lose fat in winter, but can be raised better!"

"This ......", Wang You believes that what Zhen Qian said is true, and Zhen Qian has no need to lie to himself.

"In fact, this principle is very simple, think about how the meat we usually eat is preserved, many foods have a shelf life, after the shelf life can not be eaten, even food is no exception, can the grass not use the same technology to store more when the water and grass are abundant, and wait until the green and yellow are not taken out to eat, this is not a miracle, but Gewu!"

Wang You already roughly understood what Zhen Qian was going to say, this method seemed very simple, and it was not difficult to do, the key was that no one thought of it.

Forage grass has a wide range of sources, and the nutritional value is still high after processing and adjusting into hay, which is an important source of phosphorus, calcium, vitamins and trace elements for grass-fed livestock. However, the nutritional value of hay has a lot to do with the harvesting period and the drying and storage method.

The nutritional value of grass varies greatly at different stages of growth, and generally as the grass matures, the crude fiber content will continue to increase, the protein and sugar content will decrease, and the digestibility of crude fiber will also decrease. Therefore, when drying hay, it should be harvested at the right time. Generally, grasses are harvested at the beginning of heading, and leguminous grasses are harvested at the budding stage and early flowering.

There are many ways to prepare hay, and there are two commonly used methods: the first is the ground drying method. Choose sunny and hot weather and spread the harvested grass on the grass for a few hours in the sun to form small piles before the leaves start to fall off. The other party is packed together, and the volume should not be too large. When the moisture in the grass drops to one or two percent (it can be bundled and stored in large stacks.

The second is the straw rack drying method. In wetter areas or rainy seasons, hay preparation can be done on specially made straw racks. Drying on a rack can greatly increase the drying speed of the hay and ensure the quality of the hay. Place the grass on the grass stand from top to bottom, the thickness is not too thick, and keep it fluffy and a certain slope to facilitate lighting and drainage.

Leguminous forage grasses such as alfalfa and grass clover are easy to fall off after drying, so it is best to mix them into grass powder and store them. Poaceous grass can be stacked and stored after drying, the bottom of the stack is padded with wood, artemisia stalks, etc., high above the ground, and the top should be sealed with plastic film or straw and corn straw after stacking to prevent rain. Half a month after stacking, the temperature in the stack should be checked frequently, if the temperature rises, it should be turned over and dried in time according to the situation, so as to avoid mildew.

Generally, each mu of pasture produces about 20,000 kg of green fodder per year, and cattle are multi-stomach livestock that can digest and utilize plant fiber. Non-pungent odor, tender and juicy pastures can be used to feed cattle, sheep, etc., and these grasses are mostly monocotyledonous grasses. When feeding leguminous pasture white clover and alfalfa, the same amount of ryegrass must be mixed to prevent bloating caused by cattle and sheep's greed.

The origin of alfalfa is not in the Central Plains, it was introduced to the Central Plains from the "Western Regions" in the Han Dynasty. The original name of goldenrod is alfalfa, which is a ...... leguminous plant.

Wang You found out that Zhen Qian had become a skilled shepherd, "These are all things that Da Lang came up with?" ”

"Of course not...... do you think I look like a shepherd?" How could Zhen Qian have such ability, I had seen people do this in the countryside before, but it took a lot of twists and turns to operate, mainly because it was difficult to grasp the details, but fortunately, with Zhen Qian's general directional guidance, he did not take many detours.
