Mrs. You didn't say anything.

A copy of the pig feed formula customized according to the various growth stages of Chinese black soil pigs has been mailed by her to the Animal Husbandry Department under the Ministry of Agriculture.

Speaking of which, the high-tech power of the eleventh level civilization was used, and in the end, the main raw material of the recipe turned out to be - straw!

Straw is a general term for the stems and leaves (spikes) of mature crops.

Usually refers to the remainder of wheat, rice, maize, potatoes, canola, sugarcane and other crops (usually coarse grains) after harvesting seeds.

When the straw is not ripe, part of the stem and leaf can be used to feed cattle and sheep.

However, the straw after the grain is ripe can only be dried and used as firewood!

Among the materials, the title of straw biological feed formula is very eye-catching in a blink of an eye.

The commissioner who opened the letter went directly to the signature at the end of the material.

Sure enough, as expected, patriots again!

The commissioner didn't look at the specific content of the materials, and was so excited that he grabbed the letter and rushed to the leader's office.

After a while, the entire Animal Husbandry Division was boiling!

The leader immediately grabbed the phone and shook people.

Professors of biology and zoology at Jingcheng Agricultural University were invited to the Animal Husbandry Department for tea that afternoon.

The kind that really drinks.

The leader of the Animal Husbandry Division, who did not have a few hairs left on the top of his head, had a slight trilling voice in his high-pitched voice:

"Professors, please help me evaluate the feasibility of the straw biological feed formula! If this formula can be widely used in pig breeding, it can help the majority of farmers to greatly reduce the cost of raising pigs. ”

Where do professors not know this?

They only feel that the feed formula in their hands is as heavy as a thousand gold!

Among the people who came, the most senior biology professor is also the vice president of Agricultural University.

He was most emotional:

"From the principle of this formula, by inoculating a certain amount of specific non-toxic microorganisms to ferment and enzymatically hydrolyze the straw, the straw is partially converted into sugars, lipids, proteins and other substances that can be used by animals.

This is a very forward-looking and economically valuable silage project! The food has been fed to our mouths, but there is no reason not to eat it! ”

Other professors from the Faculty of Biology joined the conversation.

A professor who has studied abroad talked eloquently:

In fact, the technology of using straw as feed can be traced back to 1900, when a well-known German chemist and professor conducted special research.

He used the straw of wheat and barley as the main fodder for cattle, horses, and sheep.

At the beginning of the experiment, even if the straw was cut to a length of two or three centimeters and eaten into the stomachs of cows, horses, and sheep, it could cause abdominal cramps and rumination was also very difficult. Later, he added the sodium hydroxide solution to the straw in a certain proportion, cooked it, and then let the cows, horses and sheep eat it.

After comparison, it was found that the digestibility of the alkalized straw after being eaten by livestock increased by 14%-17.5%. In his writings, he systematically discusses the nutrition of various straw feeds and their feeding potential"

The leaders of the Animal Husbandry Department were a little anxious when they heard this: "More than 60 years have passed, why has straw feed not been vigorously promoted in the world?" ”

The professor who returned from studying abroad shook his head and said: "Although the alkalized straw improves the digestibility, it can only maintain the growth of a specific period without concentrate. To put it bluntly, there are not many nutrients in the straw feed, and cattle, sheep and horses will not last long after eating!

The Dean of the School of Biology pointed to the formula materials and laughed:

"Straw is fermented by microorganisms, which not only solves the problem of digestibility, but also improves its palatability and nutritional value to a certain extent. In the formula, spirulina powder is used to increase protein nutrition factors for straw feed. ”

Professors of biology are naturally no strangers to spirulina.

It is a single-celled herbaceous algae that has lived on Earth for 3.5 billion years and is widely distributed in freshwater and saline lakes in tropical and subtropical regions.

The dean immediately decided: "Our agricultural conference will immediately send experts to Yunnan Province to investigate, if we can really find high-quality protein from spirulina, then the value of spirulina is not limited to feed." It's a nutritious and healthy food that can be eaten by humans. ”

The value of this project is quite far-reaching!

Professors of biology and zoology, after discussion, were very positive.

The possibility of making a highly nutritious, low-cost feed according to this pig feed formula is quite large.

Moreover, it is not confined to pig feed.

Cattle, sheep, horses, chickens, ducks, and fish can all benefit.

The leader of the Animal Husbandry Department couldn't suppress a smile on his face, and after sending off a professor, he laughed heartily.

"Hahaha, great, really good!"

Isn't that great!

In less than half a month, good news came back from Yunnan.

Experts have found a protein with a special pigment from spirulina - phycocyanin.

And the content is as high as 60%-70%, which is 2 times that of soybeans, 3.5 times that of beef, and 4 times that of eggs!

In addition to phycocyanin, spirulina is also rich in raditene, amino acids, vitamins B1, B2, B6, B12, E and K, and even zinc, iron, potassium, calcium, magnesium, phosphorus, selenium, iodine and other trace elements.

It is preliminarily judged that the chemical composition of spirulina has the characteristics of high protein, low fat and low sugar, and contains a variety of vitamins and trace elements.

Extremely nutritious.

Medical value to be developed!

The microbiology laboratory of the Agricultural University has also invested in the cultivation of specific non-toxic microorganisms.

When the straw microbial feed is baked, it will be in May and June at the earliest.

It's still spring.

Where does the straw come from?

Mrs. You does not know the feed research and development process of the Animal Husbandry Division, and she is still squatting on the pig farm.

Not only Guxian, but also the remaining seven counties of Shencheng, all major pig farms have come.

Free artificial insemination technology training, who doesn't want to learn?

Thirty sows, in the midst of all the attention, are finally mated.

All the concern is, how many cubs can a sow carry in this way of worker fertilization?

They can't see it, and they can't guess it.

You veterinarians have nanobots in hand, and everything is under control.

Within five days of breeding, the fertilized eggs in the sow have begun to divide.

This is one of the hallmarks of successful breeding!

Through internal diagnosis, the sow with the weakest physique in this pig farm is pregnant with eight cubs!

One of the best sows even conceived fifteen baby pigs.

100% success rate!

On average, each sow can give birth to ten cubs.

This probability is quite explosive.

The veterinarian has good news to share, and during the observation period, he also has to give the trainees a lesson on sow pregnancy preparation from time to time:

"In the process of pig raising, the feeding management of sows before and after breeding is a key link to ensure the healthy reproduction of sows. Today, I will talk in detail about how to feed the sows before and after breeding, and how much to feed."
