Chapter 258 Cold Matching
There are three main ways of breeding bulls and cows.

The first is natural mating, which is a relatively common method of mating. It is enough for cows and bulls to mate autonomously. It is not necessary to conduct estrus identification for cows, but it cannot do a good job in the prevention of reproductive tract diseases.

The second is artificial assisted mating.When the size difference between male and female cows is too large, and the bull cannot be mated with the cow normally, then at this time, artificial assistance is needed to assist the male and female cows to breed.

As for the third method, it is also the mainstream breeding method in the international community-cold breeding.

Artificial insemination of cows using frozen sperm is called "cold mating"!
Frozen artificial insemination of cattle is a major revolution in the history of cattle breeding, which can maximize the utilization of excellent breeding bulls.

The application of frozen sperm insemination can increase the breeding rate by 100 to 200 times compared with natural mating.

The sperm collected once can be made into 1-200 insemination doses.

The efficiency of natural mating is too low, and similar to all the [Anxi Bulls] and [Anhong Bulls] in Wu Siyuan's [Shennongjiao Space], it may not be possible for these mature cows to complete the mating work.

Although [Anxi Cattle] and [Anhong Cattle] have been in the [Shennongjiao Space], each has formed a group of thousands of heads, scattered on [-] acres of land, eating spiritual pastures, and living a life called A comfort.

But it is impossible for Wu Siyuan to take out all the cattle breeds.

The target is too big, Wu Siyuan can't explain the source.

But for these two breeds of cattle, Wu Siyuan took out [-] or [-] bulls and cows from the [Shennongjiao Space], and said that they were found in the wild, which is barely justified.

These dozens of cows are what Wu Siyuan intends to use for breeding.

Yongyuan Animal Husbandry Development Co., Ltd. has recruited a large number of professional and technical personnel.

After the bulls enter the barn, they use their professional skills to [extract sperm] from these bulls.

Then artificial insemination is used to artificially breed the cows that have entered estrus.

After several months of hard work, they finally completed the breeding work of nearly [-] cattle.

Because Wu Siyuan has the skill of [Detection], some cows with reproductive diseases, or cows with poor physique, have already been eliminated by him, and the remaining cows are all very healthy.

In the end, the conception rate of the cows was also very good, reaching 95%!

9-10 months later.

[Anxi Cattle] After mating with Chinese native yellow cattle, they successfully gave birth to more than 38.5 calves, with a newborn weight of 85kg, a body height of 71cm, a body oblique length of 83cm, a bust of [-]cm, and a yellow-brown coat color.

Its growth rate is very fast, and its weight generally reaches 450-480 kg in about half a year.

Although it is not as exaggerated as [Anxi cattle], [Anxi cattle] can reach a weight of 580 kilograms after half a year of breeding, a full weight of 100 kilograms, which is 200 catties.

But it is also much stronger than the current mainstream Simmental beef in the world.

Simmental cattle are bred for 10 to 12 months before they generally reach a weight of 500-550 kg.

And 【Anxi cattle】after one year of breeding, the weight reaches 1200 kg.

This new breed of cattle crossed with [Anxi cattle] has been bred for a year, and its average weight has reached 850 kg, which is 300-350 kg more than that of Simmental cattle in the same period.

At this time, the national average price of beef was 19.83 yuan/jin, and the price of beef in Shanghai, Guangzhou and other places was even higher, exceeding 21 yuan/jin.

But let's take the price of 20 yuan/jin to calculate.

Breeding beef cattle at the same time, Wu Siyuan's beef cattle bred with [Anxi cattle] can grow 300-350 kilograms more meat, and without considering other conditions, the economic benefits can be 12000-14000 yuan more.

Ten heads are 12-14 yuan, and one hundred heads are 120 million-140 million yuan.

What's even more rare is that the beef cattle produced by this kind of hybrid grow more meat, are not picky eaters, and inherit the advantages of the mother cattle's strong disease resistance.

Taken together, it may be lower than the cost of breeding Simmental cattle.

What's even more exaggerated is that the meat quality of this breed of cattle bred with [Anxi cattle] is still very good. The cut beef is mixed with white fat, forming a beautiful marble pattern, although it does not have the snow pattern pattern of Japanese Wagyu. So beautiful, but also has its own unique aesthetic.

It tastes tender and juicy. It is an exaggeration to say that it melts in the mouth, but it can be regarded as a lingering fragrance.

This kind of beef is completely up to the standard of American special-grade beef, even if it is used as a raw material for high-end steaks in high-end restaurants, it is more than enough.

Wu Siyuan named this hybrid cattle breed [Chinese Anxi Cattle] after the country!
On the other hand, a new type of dairy cow was also bred through crossbreeding with [An Hongniu] as the male parent and Chinese black-and-white dairy cows as the female parent.

Its body size is larger than that of the Chinese black-and-white cow as the female parent, and a little smaller than [An Hongniu]. Its body color is black, white and red.

This kind of cow, Wu Siyuan named it "Sancai Cow", and the staff of the ranch sometimes referred to them as "Colorful Cow".

As dairy cows, unlike beef cows, they are bred at one and a half years, and their calves start to produce milk after nine months, and it will take a little more than two years at the earliest.

Although by visual inspection, the growth speed of this hybrid cow inherits the advantages of the male parent, but it will take about two years at the fastest to complete breeding and then produce milk.

And now, only a year has passed.

In one year, beef cattle can be slaughtered, but dairy cows have to continue to be raised.

However, although it is still impossible to see the milk production of this hybrid cow, the staff of the ranch are very confident in it. This confidence comes from their intuition formed after years of immersion in this industry, a kind of Seeing the appearance of a cow, I have a vague intuition about its milk production.

And that intuition is often accurate.

Milk production is still uncertain, but some things are clear at a glance.

China's black-and-white cows, or cows all over the world, are livestock that are resistant to cold and not drought.

This is mainly determined by its own biological characteristics.

Dairy cows mainly use roughage, which not only has high crude fiber content in the diet, but also has a large feed intake, which increases heat consumption and heat dissipation load; dairy cows are compound stomach animals, and the feeding fermentation in the rumen not only produces methane, but also produces Heat; the milk production of dairy cows generally reaches 20-50 kg/day at present, and the increased heat production of synthetic milk is quite large. A cow with a daily lactation of 1 kg has 20% more calories than dry cows.

The so-called higher output, more heat production is the truth.

Of course, this hybrid [Tricolor Cow] cannot change this point.

However, it is more drought-tolerant than other breeds of cows. It is conservatively estimated that it is at least [-] percent higher.

This means that if this [three-color cow] is raised in the sultry south, the cost of the ventilation and heat dissipation system can be reduced a lot.
