"I guess I heard you say there are 600 cows here, right?" Geng Jingzhong turned his head and asked Steward Zhu behind him. Steward Zhu nodded hurriedly, indicating that it was right. "Six hundred is indeed a lot, and this is not a grassland dedicated to cattle breeding. Uncle Gu, help me remember it, and go back and let Luzon also increase cattle breeding. Speaking of which, the cow is a good helper for the people, and he is inseparable from anywhere! Geng Jingzhong was right, in this era, the use of animal power is the most widespread and indispensable.

"Written down!" Gu Ping replied.

"By the way, looking at the farm here, in addition to these kinds of poultry and livestock, this king remembers that there is another animal that can be raised, and its breeding speed is not slower than that of poultry, and the meat is also very delicious!" Geng Jingzhong said to the people around him with a smile. Seeing that everyone was looking at him curiously, he continued to say, "Rabbit! The taste of rabbit meat is good, and the braised rabbit meat is even more delicious, definitely not worse than ordinary braised pork! ”

The guards around him were all nodding in agreement, and Steward Zhu showed a hint of joy on his face in addition to nodding in agreement. "Back to the prince, my subordinates have just opened up a small area on the farm to try to raise rabbits, but now the number is still very small, less than a hundred!"

"Oh, you've got rabbits! Very good, take this king to see! Geng Jingzhong signaled.

Steward Zhu hurriedly took two steps forward, took the lead in one direction, and made a gesture of please at the same time. "Lord Wang, please go this way!"

Sure enough, the last part of the farm is the rabbit nest. Rabbits are an animal with a strong reproductive rate. Estrus and mating at any time. The pregnancy is only one month. Mature rabbits can give birth to six to ten in a litter. Twentieth-century Australia was plagued with rabbits, which were killed by governments and farmers, but they were just the descendants of five pairs of European rabbits that had been bred in less than a hundred years. Rabbits are herbivorous animals with low feed requirements, making them suitable for quick meat providers.

There are already hundreds of rabbits in this rabbit building in front of me, and they are quite cute when they jump up. "Well, the sanitary conditions are good, but the surrounding smell is not very good." Geng Jingzhong looked around, and saw several large pools twenty or thirty meters away. The smell came from inside. These large pools, connected to each other by channels, emit a stench. Geng Jingzhong suddenly understood that this was used to discharge poultry and livestock manure on the farm. Because the pond is very large, the farm is a large excrement household, and when washing the cage, it will also produce a large amount of wastewater rich in organic matter, although there is also a biogas digester here, but the methane digester is nothing more than treatment, so digging these large ponds, it is equivalent to a biological treatment system. Sewage and feces are first deposited in a sedimentation tank and then put into a treatment tank. Excess nitrogen and phosphorus in the water can be adsorbed by planting aquatic plants.

Of course, Steward Zhu didn't understand any of this, but there were indeed dense greenweeds floating on top of several ponds, from which workers were scooping up greenweeds, which were a good source of green fodder and compost. "Back to the prince, these pools are used for composting, and the green weeds in the ponds are also one of the sources of feed." Steward Zhu saw Geng Jingzhong staring at a few pools, so he immediately explained: "After these green weeds are chopped, the poultry like to eat them. And this thing grows fast, and his subordinates have already ordered the workers to clean it up regularly. ”

"It's okay, but it tastes a little bigger. By the way, what kind of feed is on the farm now? ”

"That's the case, there are several, now the most here are sweet potatoes and sweet potato vines, and the other is a part of corn and rice bran, and there are more and more rice bran in recent days." Steward Zhu replied.

This Geng Jingzhong is understandable, now a large amount of rice has been transported back, and the large hulling machine is constantly shelling it into rice, and the remaining large amount of rice bran has become feed in the farm. This has become a constant source of feed on the farm, and it is also readily available. "Sweet potatoes are better than rice bran, it is better to feed these livestock or use starch feed, sweet potatoes are the best choice, this thing is too yielding, and it is the most cost-effective to grow this!" Even if it is not used to raise these livestock, it can be eaten by humans, and it tastes really good. In addition, the value of sweet potatoes includes by-products produced in the deep processing of sweet potatoes, such as starch water and powder residue. Geng Jingzhong smiled and said to Steward Zhu and the others.

"You don't know this, sweet potatoes processed into vermicelli is one of the king's favorite dishes, slippery and refreshing, and you can hand it over to the palace workshop for production when you turn around." Geng Jingzhong said with a smile, for sweet potato vermicelli, he thought of it two days ago, and it was still associated with crushing sugarcane, but he didn't think about letting it be produced in the workshop, and ignored it for a while!

Considering the breeding of livestock, in addition to starch feed, another very important item is green fodder, which is mainly engaged in corn silage in modern agriculture. But at this time, because food is precious, what can be implemented is the corn stalk silage method. At present, the area of corn cultivation is not very large, but if all the land belonging to Wangzhuang is planted with corn and sweet potatoes, it is enough for these farms to consume.

"These feeds are very important for breeding, and must not be ignored, and good feed has a considerable role in promoting the growth of these livestock. Sweet potatoes have now been popularized, and there will probably be no shortage in the future. However, the king will let the farm plant some more alfalfa, which will be supplied to the various farms on a regular basis, and alfalfa is also an excellent fodder. In addition to these, the most important thing to raise livestock is protein feed, which may not you understand, but I mean such as soybean cake, peanut cake, coconut oil cake, and fishmeal made from trash fish and fish scraps to promote the growth of livestock. ”

Geng Jingzhong finally thought that there seemed to be a lot of protein powder in the feed of later generations, and grinding fish bones or bones of other animals into powder was an excellent feed. For now, Geng Jingzhong thought of wanting to make better feed, and the additives in these feeds, including calcium, can be directly recycled from eggshells and bones, and stone powder can also be added. In addition, there is no shortage of salt in it, a salt farm is not far from this side. If necessary. You can also fish for a lot of kelp and seaweed from the sea. Get some trace element supplements from this.

By-products of agricultural product processing such as straw, rice bran, and sweet potato skins are of course not as strong as real feed as feed, but they can be used as a supplement, especially after processing, and can also be better absorbed and utilized by livestock. At this time, the more I think about it, the more I feel that the source of feed is still quite extensive, and there will be no shortage of feed under the current scale of breeding.

Geng Jingzhong said as he walked, and Steward Zhu was afraid that he would not be able to remember. Hurriedly took out a small notebook and a pencil and kept recording. These are the golden rules of the prince, and if you implement them carefully, you will be able to be ahead of other stewards, and you will go further, so you can count on this little book!

The trip to the farm was only delayed for one morning, and after lunch at the farm, I came to the branch of the trading company in Houyu Port in the afternoon. In fact, the staff in the headquarters are not as many as the staff in this department, after all, this is in the port, and it is very busy. Anyway, it's all about inspecting everywhere. Just take a look, and maybe I'll have to go somewhere else later. When the interest is there, it doesn't matter where you go.

Geng Jingzhong entered the company, and saw a large number of "new products" on a table, which are said to be made by the workshop under the palace. It doesn't matter if you engage in trial production now, it's a big deal to sell it and eat it for yourself, but once it is put into mass production and unsalable, it means a huge waste, but Geng Jingzhong is not worried about this now, in order to cultivate his own talents, it is nothing to waste some money.

The most popular commodities in Houyu and Yuegang are those few items, among which glass products - including large pieces of flat glass mirrors, glassware and perfumes from Wangfu Princess Fang - are the hottest sellers. Now there is a certain amount of sales every month, and for a huge market, their production is still less.

Geng Jingzhong suddenly saw a box of things in a pile of items that he was very interested in - matches, matches are not complicated in terms of technology, people have already been able to produce red phosphorus in large quantities, originally not to make matches, but for the army's signal flares, and there is also a real room to use. Originally, the people of this era used fire sickles and flints when making fire, and they simply kept fire in the hearth all year round, so it was not difficult to use. But in comparison, matches are more used, mainly because of convenience! Matches have been around for a long time, but this one is just better.

In addition to seeing a box of matches, what interested Geng Jingzhong was a few boxes of snacks with very good packaging. This thing is also something that is exported to the outside world, and it is a local specialty, and it sells well. Geng Jingzhong tasted two pieces, and the taste was indeed very good, but Geng Jingzhong immediately thought of a problem, food hygiene, before the later generations crossed by themselves, the people of the country were most worried about the food safety, but there are no additives in this era, even if you want to eat Sudan dyes, you can't find it. But Geng Jingzhong still wants to go to the food processing workshop to have a look, don't be like the small workshop in later generations, dirty and messy, and then let yourself vomit!

When Geng Jingzhong came to the nearest food factory, the starch workshop was in operation. Obviously, this is a workshop specializing in starch processing, and the main ingredient is sweet potatoes. The huge machine in front of me is specially used to wash sweet potatoes, and the two mules are constantly turning in circles. The structure of this machine is also very simple, but it is the latest product applied to the military workshop. The machine is still tumbling, and hundreds of catties of sweet potatoes are also floating in the water with the rollers fluctuating up and down in the cement tank. Not far from the potato washing machine, there are several different machines installed, all of which are rumbling. In the morning, he also said that he was going to let the workshop below produce sweet potato flour, there is already a workshop for processing sweet potato flour here, and the machine in it is still so advanced, at least in Geng Jingzhong's opinion, it is ahead of this era.

It seems that the town cannot underestimate the ancients, who said that the Chinese are not good at inventing, this machine in front of you is already very good! There are two new products in the latest military workshop. Actually, it really counts. There is only one. It's the bearing. The other is gears, which have been widely used for a long time. Gears may seem simple, but they are actually very technical and can be said to be a sign of industrial society. Ancient societies also had gears, whether in China or Europe, there are records of gear systems. But gears in the modern sense originated from the gear involute proposed by the mathematician Euler in 1765. With the basic law of involute gears and tooth profile meshing, high-speed gearing is possible without involute gears. There can be no high-speed transmission, there can be no gearbox, and without a gearbox, it is impossible to use any kind of powerful kinetic energy efficiently.

There was no suitable steel for gears before, but after the No. 1 special steel came out, the R&D personnel have successively developed several high-performance special steels, and these special steels are used to make gears, which have indeed become more durable.

Not far from the drum where the sweet potatoes are washed is a potato mill. This is a big guy with a wooden drum on the Taiwan Railway Shaft, and the wooden drum is densely covered with iron half-split eyes. The upper grinding knife is detachable. In order to change the knives of different sizes at any time, the thickness of the potato pulp can be controlled. This machine may not look good, but it can process six or seven hundred kilograms of sweet potatoes per hour. The sweet potato pulp that comes out of the potato mill should be washed and sifted, this kind of thing is called a trommel sieve, and the material of the sieve cloth is silk, which has relatively fine pores, but has superior water seepage performance.

After sifting, the starch in the potato pulp flows out with the water to become starch milk, and the rest is potato residue. Potato residue has a number of utilization values, mainly used to make alcohol, the residue after the preparation of alcohol can also be used as fermented feed, and the starch milk can be precipitated to obtain starch finished products. Further inside are the sedimentation tanks, all of which are cement tanks, each tank is 20 meters long, and can process 1,000 kg to 1,500 kg of sweet potatoes every eight hours, and the efficiency is very good.

The starch slurry entering the sedimentation tank needs to be "slurred", which is actually the traditional Chinese soil method of starch making. The sour pulp mixed into the starch slurry is obtained by fermentation of natural lactic acid bacteria in the starch production process, and the appropriate amount of sour slurry added to the starch milk can promote the rapid condensation and deposition of starch. Starch sinks quickly, deposited at the bottom, and above is a conglomerate of fiber and protein, and the two are clearly demarcated. This process not only accelerates the separation of starch from impurities, but also inhibits the activity of other impurities with lactic acid bacteria.

What is precipitated is starch, and the upper layer is a sticky yellow starch that contains a lot of impurities. The middle layer of starch is of the best quality, and after taking it out, it is dehydrated and dried to make it the best starch. The lower layer contains more soil and impurities, and the starch of the first layer is mixed with water and slurry after filtration and precipitation, and the second grade of starch can be prepared.

The clarifier in the upper layer of the sedimentation tank is taken out and placed in the water tank, and allowed to ferment into "old pulp", which can be used the next day. The remaining wastewater contains a small amount of starch, and the crude fiber and protein sediment in the wastewater are deposited in the wastewater pond to become potato yoshi. The starch can be extracted after the potato yolk is sieved and precipitated again, and the remaining potato yolk can be used like potato residue. The process and process flow of the entire starch workshop are so close to the methods of processing sweet potatoes in later generations, Geng Jingzhong was stupid for a while, which reminded him of his childhood, when he made this at home, and he couldn't be more familiar!

Geng Jingzhong watched the processing of sweet potatoes, and his original intention of checking the health situation also faded, and he kept thinking back to the past. I was in no mood so I turned to other places to relax, just by the sea, the palace had already built a seaside manor according to his instructions, and in the future it would be a luxurious sea-view villa. Geng Jingzhong sat in the carriage, although the carriage shook a little when it ran over some obstacles on the road, it did not slow down at all, and the shock-absorbing leaf springs creaked under the body, but it withstood the test. The carriage drove all the way to a small cove surrounded by sand dunes, and behind the bay was a small fishing village called Xingzhuang.

Looking out of the boats and grass huts perched on the beach, there are only two brick and stone buildings near the fishing village, one a church and the other a two-storey villa on the slope of the harbour, surrounded by a wooden fence. This building is completely Western-style, against the seaside, standing higher to feel more beautiful, a water of floor-to-ceiling windows, looking at the beautiful scenery of the seaside, and a pot of wine, is really a good place to relieve worries, is the lack of a beauty massage here, otherwise it will be more beautiful!

The trip to the farm was only a morning delay. Had lunch at the farm. In the afternoon, I came to the branch of the trading company in Houyu Port. In fact. Now the staff in the headquarters is not as many as the staff in this branch, after all, this is in the port, and it is very busy.

Geng Jingzhong entered the company and saw a large number of "new products" on a table. It is said that these are all made by the workshops under the royal palace, and it seems that the things that he had asked those "modern scientists" to try to develop have been made into real things, and the things that Geng Jingzhong asked the guys in the real room to develop are all things that "may be used". It doesn't matter if you engage in trial production now, it's a big deal to sell it and eat it for yourself, but once it is put into mass production and unsalable, it means a huge waste, but Geng Jingzhong is not worried about this now, in order to cultivate his own talents, it is nothing to waste some money.
