Chapter 384 Feed

"Will it degenerate after breeding like this?"

"There is one point, but it's not a big problem. The existing black-and-white dairy cows in China are basically the products of a few Dutch black-and-white dairy cows bred with local cows in the 19th century. The milk production is not bad, and they are resistant to rough feeding. The disadvantage is that The milk fat content is low." Yang Baogui said with a smile, "Some people often say that domestic milk tastes bland and not as rich as foreign milk. In addition to adulteration, this is also a factor."

"With a lot of cows, we can implement the 'school milk' plan, which will greatly improve the physical fitness of the next generation! At least every time traveler can have milk to drink every day."

"In fact, I think dairy products, such as cheese, are more promising." Yang Baogui said, "Chinese people are not very tolerant to lactose, so dairy products are fine. Besides, dairy products are easy to preserve—the conditions here are harsh. , I’m afraid it won’t work to preserve fresh milk.”

Then I walked past the corrals of several cows, of various breeds besides pregnant cows.Bulls** of several different breeds in liquid nitrogen tanks are now mated to native cows.Some are for pure meat, and some are for dual use.

Behind the cowshed is the sheep pen, and there are very few sheep in the pen, only a few dozen.These are Changhua sheep that were recently shipped from Changhuabao.It seems that they are not well adapted to captivity, and the rams try to hit the fence from time to time.

After these sheep are ready to be raised for a stage, ewes with better quality are selected for artificial insemination. The Council of Agriculture also has several fine breeds of goats and sheep.However, Yang Baogui was not sure whether sheep were suitable for Lingao—it was better to occupy areas with higher latitudes and then breed them.

The nearby shepherd dog ran out and barked loudly to restore order to the flock.

"Beibei stop barking!" Yang Baogui yelled, and suddenly a group of dogs ran over and wagged their tails at him, some of them were puppies.

"Look, 'Huanhuan', 'Yingying', and 'Nini' are all hero mothers. They gave birth to more than 20 puppies in just half a year." Seeing Wu Nanhai grab one and couldn't put it down, "I'll give you one. "

"Forget it, everyone has a bad impression of having a dog." Although Wu Nanhai felt reluctant, he let it go.

"That's right, several girls asked me for dogs, but I didn't give them." Yang Baogui said, "They must be domesticated and distributed to various departments. Ma Qianju also wants to set up a military dog ​​team or something. The General Guard wants it too."

"Having a dog guarding the gate makes me feel more at ease." Wu Nanhai thought about it, "Are there local dogs? I might as well catch a dog and guard the gate."

"Of course there are. I caught a few and wanted to see if I could make a localized hybrid. This is a typical Chinese pastoral dog. The level of domestication is very low. I'm afraid it may be more likely to be eaten as a meat dog. Big cats are better.” Yang Baogui said, “Although cats and dogs do not produce benefits by themselves, they are of great help to agricultural production. When the size of the flock expands, I will arrange for them to be herded, which requires dogs. Helped."

Yang Baogui suggested: In addition to raising poultry in the promotion plan, promoting sheep raising is also a good project.Sheep are resistant to rough feeding, easy to care for, do not require special feed, and require little labor.Both women and children can herd sheep, which is the most common project in poverty alleviation.

Wu Nanhai shook his head: "The sheep have caused too much damage to the vegetation."

"It is an arid and semi-arid area in Northwest China, where there is abundant rainfall and vegetation on the ground, which cannot be destroyed by a few sheep. Besides, a farmer can raise a dozen sheep at most, and 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 him-it's easy to deal with eating 10 chickens, but it's difficult to eat a few of our sheep. If he is pursued, he will go bankrupt, if he is not pursued, this activity will not 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 whole farm, the rabbit building had the best cooling conditions - it was built directly under the big tree, but the rabbits were still listless and refused to reproduce, which made Yang Baogui scratching his head - should we give them an air conditioner or something? ?In the late autumn of Lingao, they finally sprouted in spring.Rabbits have a high reproductive rate, and they can estrus and mate at any time. The pregnancy period is only one month, and mature rabbits can give birth to 6 to 10 in one litter. In the 20th century, the rabbits in Australia were overrun, and the government and farmers killed them endlessly. They were nothing more than the descendants of five pairs of European rabbits bred in 100 years.

Rabbits are herbivorous animals with low feed requirements and are very suitable fast meat providers.

Now, there are more than 30 rabbits in this once-expanded rabbit building, 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 Hairy.

"Rabbits don't breed in summer, so we have to wait until autumn." Yang Baogui said, "I think we will be able to eat rabbit meat by the end of the year. Our Ministry of Health also needs rabbits."

"Dissect it to the Ministry of Health first, and then serve it to everyone."

"It's okay to use it for physiological anatomy, but not for pathological experiments."

"Naturally." Wu Nanhai suddenly remembered, "I remember there are wild rabbits in Lingao, but you never thought of using local wild rabbits to improve and expand the population."

"It's not very suitable. And the rabbit belt may carry the virus, and it will be miserable if it spreads."

Finally, they came to the wasteland near the river, which was already close to the highest water level of the Wenlan River in summer. Peanuts and watermelons were planted in the sandy soil. stench.Wu Nanhai knew that this was Tian Jiujiu's biochemical sewage treatment system.The farm is a large sewage household, and washing the cages will produce a large amount of waste water rich in organic matter, which can only be treated with a biogas digester, so a biological treatment system has been set up. The sewage is first settled in a sedimentation tank, and then put into a treatment tank. The method of planting aquatic plants absorbs excess nitrogen and phosphorus in water.

There are dense green stalks floating on several ponds, and the laborers are fishing for green stalks from the ponds-green stalks are a good source of green fodder and compost.Not far from here is the silo of the farm.

"The green duckweed in the pond is also a source of feed." Yang Baogui asked Wu Nanhai seriously: "The Council of Agriculture seems to have great expectations for the breeding industry. I just want to know if you have considered the feed? Know that there is no farming without food.”

"Of course I did."

Wu Nanhai talked about the feed solution and planned to solve it through three links.

The main starchy feed is ready to use to expand the settlement of sweet potato cultivation.Including the sweet potato itself and the by-products produced in the deep processing of sweet potatoes, such as starch water and powder residue.

The second is green fodder. In modern agriculture, corn silage is mainly used.Because food is precious in China, the corn stalk silage method is implemented.In the Lingao Agricultural Committee, there is no corn at all, but silage, alfalfa and other leguminous fodder crops, as well as sweet potato leaves.In addition, high-yield vegetables such as pumpkins and zucchini on scattered land such as "Ten Sides" can also provide part of the feed.

The most important protein feed, one is to cultivate earthworms and fly maggots, and the other is to recycle by-products in oil extraction operations, such as bean cakes, peanut cakes, and coconut oil cakes.The seafood factory in Bopu can also provide fishmeal made from some miscellaneous fish and fish scraps.

As an additive in the feed, calcium can be directly recycled from eggshells and bones, or stone powder can be added.They don't lack salt, and if necessary, they can get some trace elements from kelp and seaweed.

The by-products of agricultural product processing such as rice straw, rice bran, and sweet potato skin are not ideal as feed, but they can be used as a supplement, especially after processing, they can also be better absorbed and utilized by livestock.

In this way, the sources of feed are still quite extensive, and under the current scale of farming, there will not be a shortage of feed.According to the estimates of Fa Shilu and others, the feed supply will be quite abundant after the sweet potatoes are harvested in the second half of the year, which also happens to catch up with the peak of livestock calving in autumn of that year.

"Last time, Fa Shilu told me that we should use our brains and not always think about corn and sweet potatoes. You can also get a lot of supplements from wild plants-in the past, children in rural areas had to pluck grass to feed pigs."

"Is there such a plant in Lingao?"

"Of course there are. They are all common plants in various places. Weeds of the grass family, such as thrift grass, foxtail grass, horseshoe grass, alkali grass, and barnyard grass, are used for beating and silage to feed pigs, and the effect is good. Weeds of the leguminous family are not used. Having said that, everyone knows that wild vegetables such as gray vegetables, pig hair vegetables, spiny vegetables, purslane, wild amaranth, chicory, beef tongue, and Lara vine can all be fed raw or fermented. There are green leaves, such as poplar leaves, willow leaves, elm leaves, mulberry leaves, etc. Although it cannot be said that they are everywhere, it is not uncommon. You can also get a lot of them by mobilizing students and semi-labor forces in the commune as side jobs. "

"To be honest, I really wanted to bring water hyacinths here at the time. Tons and tons of these things can be picked up in the river, and they can be piled up into dams when they erupt in summer. It is much more efficient than your human sea tactics to collect fodder. .”

"Forget about this invasive species. In the long run, there will be endless troubles. Let's not repeat the mistakes of the past. Green duckweed is enough. I originally planned to bring tilapia and crayfish. Later, it was rejected. "

This issue has caused great controversy in the material preparation stage before the crossing, including tilapia, crayfish and the like have fallen out of the debate.In the end, it was decided not to bring any of these controversial species. Anyway, they all exist on the earth, and they can be raised on the spot when they are needed someday.

"Crayfish are good, what a pity. Everyone loves them."
