"Will it degrade after breeding like this?"
"A little bit, but it's not a big problem. [No pop-up novel website] The existing Friesian dairy cows in China are basically the product of breeding several Dutch Friesian dairy cows and local cows in the 19th century. The milk production is pretty good. It is also resistant to rough feeding. The disadvantage is that the milk fat content is low." Yang Guogui said with a smile, "Some people often say that domestic milk has a bland taste and is not as pure and honest as foreign milk. In addition to adulteration, this is also a factor."
"With a lot of cows, we can implement the 'school milk' program, which will greatly improve the physical fitness of the next generation! At the very least, every time traveler can have milk to drink every day."
"Actually, I think dairy products, such as cheese, are more promising." Yang Baobao said, "Chinese people are not very intolerant to lactose, so dairy products are no problem. And dairy products are easy to preserve - the conditions here are harsh. , I’m afraid it’s not possible to preserve fresh milk.”
Then we walked past the corrals of several cows, not only those carrying suckling cows, but also those with other breeds. Semen from several different breeds of bulls in tanks of liquid nitrogen is now paired with local cows. Some are purely for meat, and some are for dual use.
After the cowshed is the sheep pen. There are very few sheep in the pen, only a few dozen. These are Changhua sheep that were recently transported from Changhua Fort. It seems that they are not quite used to being kept in captivity, and from time to time, rams try to hit the fence.
After these sheep are prepared to be raised for a period of time, ewes with better quality will be selected for artificial insemination. The Agricultural Committee also has semen from several high-breed goats and sheep. However, Yang Baobao was really not sure whether sheep were suitable in Lingao - it would be better to occupy areas with higher latitudes and then breed them.
The nearby shepherd dog ran out, barking loudly, to restore order to the flock.
"Beibei, stop barking!" Yang Guogui shouted, and suddenly a group of dogs ran over and waggled their tails at him, some of them puppies.
"Look, 'Huanhuan', 'Yingying', and 'Nini' are all heroic mothers. They have given birth to more than 20 puppies in just six months." Wu Nanhai grabbed one and couldn't put it down, "I'll give you one as a gift." .”
"Forget it, raising a dog will give everyone a bad impression." Although Wu Nanhai felt reluctant to let go, he still let it go.
"Yes, several girls asked me for dogs but I didn't give them to them." Yang Guogui said, "They need to be domesticated and then distributed to various departments. Ma Qianzhu also wants to set up a military dog team or something. The General Security Administration wants it too.”
"It will make you feel more at ease if you have a dog at the door to watch the door." Wu Nanhai thought about it, "Are there native dogs in the local area? I might as well catch a native dog to watch the door."
"Of course there is. I caught a few of them and wanted to see if I could make a localized hybrid. These are typical Chinese pastoral dogs. The level of domestication is very low. I'm afraid they are more likely to be beaten and eaten as meat dogs. Bigger. Cats are better." Yang Guigui said, "Although cats and dogs do not produce benefits themselves, they are of great help to agricultural production. When the size of the sheep herd expands, I will arrange for herding, which requires dogs. Helped."
Yang Baoguo suggested: In addition to raising poultry, it is also a good project to promote sheep raising in the promotion plan. Sheep are resistant to rough feeding, are easy to care for, do not require special feed, and require very little labor. Women and children can herd sheep, which is the most common project in poverty alleviation.
Wu Nanhai shook his head: "Sheep cause too much damage to the vegetation."
"It is an arid and semi-arid area in northwest China. It has abundant rainfall and rich surface vegetation, which cannot be destroyed by a few sheep. Besides, a farmer can only raise a dozen sheep at most, so the land carrying capacity is very small."
Wu Nanhai was moved and said: "Let's wait until the promotion of this batch of chickens is successful. Only responsible farmers can give it to them - it is easy to handle 10 chickens, but it is difficult to handle a few of our sheep." He will go bankrupt if he is held accountable, and if he is not held accountable, this activity will not be able to continue in the future.”
The last part of the livestock farm is the rabbits. The rabbit was not happy living here at first - it was too hot. At that time, among the livestock in the entire farm, the rabbit building had the best cooling conditions - it was built directly under the big tree. However, the rabbits were still listless and refused to breed. This made Yang Guigui scratch his head - should we get them an air conditioner or something? ? In the late autumn of Lingao, they are finally in spring mood. The reproductive rate of rabbits is very strong. They can mate at any time. The pregnancy period is only one month, and a mature rabbit can give birth to 6 to 10 children. In the 1st century, rabbits in Australia were overrun. The government and farmers killed them incessantly, but only five pairs were killed. They are just descendants of European rabbits bred over the past 100 years.
Rabbits are herbivorous animals and do not require high feed requirements, making them a very suitable and fast meat provider.
Now, there are more than 30 rabbits in this once-expanded rabbit house, 10 of which are long-haired rabbits - Wu Nanhai recognized them at a glance. In order to let the long-haired rabbits spend the summer safely, these rabbits were shaved Got hairy.
"Rabbits don't breed in summer, so we have to wait until autumn." Yang Guogui said, "By the end of the year, we will probably be able to feed everyone with rabbit meat. Our Ministry of Health also needs rabbits."
"We'll do an autopsy for the Ministry of Health first. After the autopsy is done, we'll have it ready for everyone to eat."
"It can be used for physiological anatomy, but not for pathological experiments."
"Of course." Wu Nanhai suddenly remembered, "I remember there were hares in Lingao, but you have never thought of using local hares to improve and expand the population."
"It's not very suitable. And the hare tape may carry viruses, which would be disastrous if it spreads."
Finally, they came to the wasteland near the river. It was close to the highest water level of the Wenlan River in summer. Peanuts and watermelons were planted in the sandy soil. There were several large pools a little further away, connected by channels and scattered. Stink. Wu Nanhai knew that Tian Jiujiu had created the biochemical sewage treatment system. The breeding farm is a large consumer of sewage, and flushing the cages will produce a large amount of wastewater rich in organic matter. The biogas digester alone cannot handle it, so a biological treatment system was built. The sewage is first settled in the sedimentation tank, and then put into the treatment tank. The method of planting aquatic plants absorbs a large amount of nitrogen and phosphorus in the water.
There are densely packed green algae floating on several ponds, and workers are fishing for green algae from the ponds - green algae is a good source of green fodder and compost. Not far from here is the silage pond of the breeding farm.
"The green apples in the pond are also a source of feed." Yang Guogui asked Wu Nanhai seriously: "The Agricultural Committee seems to have great expectations for the breeding industry. I just want to know, have you considered the feed? Yes. We know that without food, there would be no farming industry.”
"Of course I've considered it."
Wu Nanhai talked about the feed solution and planned to solve it through three links.
The most important starchy feed preparation is the solution for expanding sweet potato cultivation. Including sweet potatoes themselves and by-products produced during the deep processing of sweet potatoes, such as starch water and flour residue.
Next is green fodder. In modern agriculture, corn silage is mainly used. In China, because food is precious, the corn straw silage method is promoted. In the Lingao Agricultural Committee, we don’t even have corn. We use alfalfa silage and other leguminous feed crops, as well as sweet potato leaves. In addition, growing high-yield vegetables such as pumpkins and zucchini on scattered land such as "Shibian" can also provide part of the feed.
The most important protein feeds are, first, the cultivation of earthworms and fly maggots, and second, by recycling by-products from oil extraction operations, such as soybean cakes, peanut cakes, and coconut oil cakes. The seafood factory in Bobu can also provide fishmeal made from some trash fish and fish scraps.
As an additive in feed, calcium can be directly recycled from eggshells and bones, or stone powder can be added. They have no shortage of salt to begin with, and if necessary, they can get some trace element supplements from kelp and seaweed.
The by-products of agricultural product processing such as rice straw, rice bran, and sweet potato peels are not ideal as feed, but they can be used as a supplement, especially after processing, and can be better absorbed and utilized by livestock.
Calculated in this way, the sources of feed are still quite wide, and there will not be a shortage of feed under the current scale of breeding. According to estimates by Fashilu and others, the feed supply will be quite abundant after the sweet potato harvest in the second half of the year, which will coincide with the peak of livestock calving in the autumn of that year.
"Fa Shilu told me last time that we need to use our brains and don't always think about corn and sweet potatoes. We can also get a lot of supplements from wild plants - in the past, children in rural areas had to collect grass to feed pigs."
"Is there such a plant in Lingao?"
"Of course. They are common plants everywhere. Graminaceae weeds such as thrift grass, foxtail grass, horseshoe grass, alkali grass, barnyard grass and other grasses are used for pulping and silage feeding to pigs, and the effect is good. Weeds from the leguminous family are not used. I have said it, everyone knows it. Wild vegetables such as gray cabbage, balsam pear, spinach, purslane, wild amaranth, chicory, ox tongue, and radish can all be fed raw or fermented. Also, There are green leaves, such as poplar leaves, willow leaves, elm leaves, mulberry leaves, etc. Although they cannot be said to be everywhere, they are not uncommon. Students and semi-laborers in communes can also get a lot of them as side jobs. "
"To be honest, I really wanted to bring water hyacinth at that time. Tons of water hyacinth can be collected from rivers. When it explodes in summer, it can pile up into dams. It is much more efficient than using the human sea tactic to collect feed. .”
"It's better to forget about this invasive species. In the long run, there will be endless consequences. Let's not make the mistakes of our predecessors again. Green duckweed is enough. I originally planned to bring tilapia and crayfish, but later rejected them. "
This issue caused great controversy during the material preparation stage before the crossing, including tilapia, crayfish, etc., which were lost in the debate. In the end, it was decided that these controversial species would not be brought. Anyway, they all exist on the earth, and they can be cultivated locally when needed.
“The crayfish is pretty good, what a pity. Everyone loves it!~!
