"A little bit, but it's not a big problem. The existing Friesian dairy cows in China are basically the product of breeding several Dutch Friesian dairy cows with local cows in the 19th century. The milk production is pretty good, and they are resistant to rough feeding. The disadvantage is
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 pure 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 I walked past the corrals of several cows. In addition to pregnant cows, there were also cows of various breeds. The bull semen of several different breeds in the liquid nitrogen tanks were now mixed with local cows. Some of them were pure meat.
There are also dual-purpose models.
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 adapted to being raised in captivity. From time to time, rams try to
Hit the fence.
After these sheep are prepared to be raised for a period of time, better quality ewes will be selected for artificial insemination. The Agricultural Committee also has semen from several fine-bred goats and sheep. However, Yang Guigui is not sure whether sheep are suitable for Lingao.
――It’s better to occupy areas with higher latitudes and then breed them.
The shepherd dog nearby ran out and barked 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 Baogui 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 to guard the door." Wu Nanhai thought about it, "Are there native dogs in the local area? I might as well catch a native dog to guard the door."
"Of course there is. I have caught a few 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 Baogui said, "Although cats and dogs do not produce benefits themselves, they are of great help to agricultural production. When the size of the flock expands, I will arrange for herding, which requires dogs.
Helped."
Yang Guigui suggested that in addition to raising poultry, sheep raising is also a good project in the promotion plan. Sheep are resistant to rough feeding, 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 practice in poverty alleviation.
s project.
Wu Nanhai shook his head: "Sheep cause too much damage to the vegetation."
"It is an arid and semi-arid area in northwestern 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's easy to deal with eating 10 chickens, but it will be difficult to eat a few of our sheep."
If he is held accountable, he will go bankrupt. 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 rabbits were very unhappy living here at first - it was too hot. Among the livestock in the entire farm at that time, the rabbit building had the best cooling conditions - it was built directly under the big tree, but the rabbits still
They were listless and refused to breed, which made Yang Guoguo scratch his head - should we get them an air conditioner or something? In the late autumn of Lingao, they finally showed signs of spring. The reproductive rate of rabbits is very strong, and they can come into heat and mate at any time.
, the gestation period is only one month, and a mature rabbit can give birth to 6 to 10 rabbits in one litter. In the 20th century, Australia was overrun with rabbits, and the government and farmers killed them incessantly. They are just the descendants of five pairs of European rabbits bred in 100 years.
Rabbits are herbivorous animals and have low feed requirements, making them a very suitable and fast meat provider.
Now, there are more than 30 rabbits in this rabbit house that has been expanded once, 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."
"Let's do an autopsy for the Ministry of Health first. After the autopsy is done, it will be 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. Moreover, the hare tape may carry viruses, which would be disastrous if it spreads."
Finally they came to the wasteland near the river, which 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, exuding
The smell. Wu Nanhai knew that this was the biochemical sewage treatment system built by Tian Jiujiu. The breeding farm is a large consumer of sewage. Washing the cages will produce a large amount of wastewater rich in organic matter. It is useless to treat it with a biogas pool alone, so he built a biochemical sewage treatment system.
In the treatment system, the sewage is first sedimented in the sedimentation tank, and then put into the treatment tank. The excess nitrogen and phosphorus in the water are absorbed by planting aquatic plants.
There are densely packed green algae floating on several ponds, and workers are fishing the 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 farm.
"The green apples in the pond are also a source of feed." Yang Guogui asked Wu Nanhai seriously: "The Committee of Agriculture 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 is prepared to expand sweet potato cultivation. It includes the sweet potato itself and the 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, there is not even corn, but alfalfa and other leguminous fodder are used.
Crops include sweet potato leaves. In addition, high-yielding vegetables such as pumpkins and zucchini grown on scattered land such as "Shibian" can also provide part of the feed.
The most important protein feeds are, firstly, the cultivation of earthworms and fly maggots, and secondly, by recycling the by-products of oil extraction operations, such as soybean cakes, peanut cakes, and coconut oil cakes. The seafood factory in Bopu can also provide some trash fish and fish scraps.
Fishmeal made from raw materials.
As additives in the feed, calcium can be made directly from eggshells and bones, or stone powder can be added. Salt is not lacking in them, and if necessary, some trace elements can be supplemented from kelp and seaweed.
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 the estimates of Fa Shilu and others, the feed supply will be quite abundant after the sweet potato harvest in the second half of the year, which is just right.
Catch up with the peak of livestock calving in autumn 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 there are. They are common plants everywhere. Graminaceae weeds such as thrift grass, foxtail grass, horseshoe grass, alkali grass, barnyard grass and so on are used to make pulp and feed silage to pigs, and the effect is good. Weeds from the leguminous family are not used.
As I said, everyone knows that wild vegetables such as gray cabbage, balsam pear, thorngrass, 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 it cannot be said that they are everywhere, they are not uncommon. You can also get a lot of them by mobilizing students and semi-laborers in the commune as a side job.
"
"To be honest, I really wanted to bring water hyacinth at that time. Tons of water hyacinth can be fished out of rivers, and it can pile up into dams when it breaks out in summer. 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, the consequences will be endless. Let's not make the mistakes of our predecessors again. The green duckweed is enough. I originally planned to bring tilapia and crayfish, but I rejected it later.
"
This issue caused great controversy during the material preparation stage before the time travel, including tilapia, crayfish and the like. They all fell out of the debate. In the end, it was decided not to bring these controversial species because they all exist on the earth anyway.
, just breed it on the spot when needed.
"The crayfish is pretty good, what a pity. Everyone loves it."
