There are three main ways of breeding bulls and cows.
The first is natural mating, which is a relatively common breeding method that allows cows and bulls to mate independently. There is no need to identify the cows for estrus, but it cannot prevent reproductive tract diseases. p>
The second type is artificial assisted mating. When the size difference between male and female cows is too large and the bull cannot mate with the female cow normally, then artificial assistance is needed to mate the male and female cows.
As for the third method, it is also the mainstream breeding method in the international community today - cold breeding.
Artificial insemination of cows using frozen eggs is called [cold breeding]!
Cattle cryopreservation and artificial insemination 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 in one session can be used to produce 200-400 insemination doses.
The efficiency of natural mating is too low, and all the [Anxi Bulls] and [Anhong Bulls] in Wu Siyuan's [Shen Nongjiao Space] may not be able to complete the mating work of these mature cows.<
/p>
Although [Anxi cattle] and [Anhong cattle] are already in the [Shen Nongjiao Space], they have each formed a group of thousands of cattle, scattered on 2,500 acres of land, eating grass full of spiritual energy, and living a life called
A comfort.
But it is impossible for Wu Siyuan to take out all the breeds of cattle.
The target was too big, and Wu Siyuan could not explain the source.
But for these two types of cattle, Wu Siyuan took out twenty or thirty bulls and cows from [Shennongjiao Space] and said that they were found in the wild. This is barely justified.
These dozens of cows are what Wu Siyuan plans to use for breeding.
Yongyuan Animal Husbandry Development Co., Ltd. has recruited a large number of professional technical personnel.
After the cattle enter the cowshed, they use their professional skills to [collect semen] from these cattle.
Then artificial insemination is used to artificially breed the cows that have entered the estrus period.
After working hard for several months, they finally completed the breeding of nearly 20,000 cattle.
Because Wu Siyuan has the skill of [Detection], some cows with reproductive diseases or cows with poor physical condition have been eliminated by him, and the remaining cows are all very healthy. p>
In the end, the pregnancy rate of the cow was also very good, reaching 95%!
9-10 months later.
[Anxi Cattle] successfully gave birth to more than 8,600 calves after mating with Chinese local fine-bred cattle. The birth weight is 38.5kg, the body height is 85cm, the body length is 71cm, the chest circumference is 83cm, and the coat color is yellowish brown.
It grows very quickly, and its weight generally reaches 450-480 kilograms in about half a year.
Although not as exaggerated as [Anxi cattle], the weight of [Anxi cattle] after half a year of breeding can reach 580 kilograms, which is a full weight of 100 kilograms, which is 200 pounds.
But it is much more powerful than Simmental cattle, the current mainstream beef cattle in the world.
Simmental cattle generally reach a weight of 500-550 kilograms after 10 to 12 months of breeding.
If [Anxi cattle] are bred for one year, their weight will reach 1,200 kilograms.
After one year of breeding, this new breed of cattle was hybridized with Anxi cattle, and its average weight reached 850 kilograms, which was 300-350 kilograms more than the Simmental cattle in the same period.
At this time, the national average price of beef is 19.83 yuan/jin, and the price of beef in Shanghai, Guangzhou and other places is even higher, exceeding 21 yuan/jin.
But let’s use the price of 20 yuan/jin to calculate.
At the same time, beef cattle are bred, and beef cattle like Wu Siyuan's crossbred Anxi cattle can grow 300-350 kilograms more meat. Without considering other conditions, they can achieve more economic benefits.
Ten heads are worth 120,000-140,000 yuan, and one hundred heads are worth 1.2 million-1.4 million yuan.
What’s even more rare is that the cross-bred beef cattle have a lot of meat, are not picky eaters, and inherit the advantages of their parent cattle’s strong disease resistance.
Taken together, the cost may be lower than raising Simmental cattle.
What’s even more exaggerated is that the meat quality of this type of cattle bred from [Anxi cattle] is quite good. The cut beef is mixed with white fat, forming a beautiful marble pattern, although it does not have the snowflake pattern of Japanese Wagyu beef.
So beautiful, but also has its own unique beauty.
It tastes tender and juicy. It's an exaggeration to say it melts in your mouth, but it can still be said to leave a lasting flavor in your teeth.
This kind of beef is completely up to the standard of American special grade beef. Even if it is used as the raw material for high-end steaks in high-end restaurants, it is more than enough.
Wu Siyuan named this cross-breed cattle [Chinese Anxi cattle] after the country!
On the other hand, using [Anhong Niu] as the male parent and Chinese black and white cows as the female parent, a new type of dairy cow was also bred through crossbreeding.
The body size is larger than the Chinese black and white cow as the female parent, and smaller than the [Anhong cow]. The body color is black, white and red.
Wu Siyuan named this kind of cow [three-color cow], and the ranch employees sometimes call them [color cow] for short.
As dairy cows, unlike beef cattle, they are bred every year and a half, and their calves begin to produce milk nine months later, which can take a little more than two years at the fastest.
Although visual inspection shows that the growth rate of the hybrid cows inherits the advantages of the male parent, it will take about two years at the fastest to complete breeding and produce milk.
And now, only one year has passed.
In one year's time, beef cattle can be put out for slaughter, but dairy cows must continue to be raised.
However, although it is not yet possible to tell the milk production of this kind of hybrid cow, the ranch staff are very confident in it. This confidence comes from their many years of immersion in this industry and they have formed an intuition and a kind of
When I see the appearance of a cow, I have a vague intuition about its milk production.
And this intuition is often very accurate.
Milk production cannot be determined yet, but some things are clear at a glance.
China’s black-and-white cows, or cows all over the world, are livestock that are cold-tolerant but not drought-tolerant.
This is mainly determined by its own biological characteristics.
Dairy cows mainly feed on roughage, which not only contains high crude fiber content in the diet, but also consumes large amounts of feed and consumes a lot of heat, which increases the heat dissipation load. Cows are animals with multiple stomachs, and the fermentation of feed in the rumen not only produces methane, but also produces
Heat; the milk production of dairy cows currently generally reaches 20-50 kilograms per day, and synthetic milk increases heat production considerably. A cow that produces 20 kilograms of milk per day has 50% more calories than a dry cow.
This is the saying goes that the higher the yield, the more heat is produced.
Of course, this kind of cross-bred [three-color cow] cannot change this.
However, it is more drought-tolerant than other breeds of cows. A conservative estimate is that it is at least 30 percentage points higher.
This means that if this kind of [three-color cows] are raised in the sweltering south, the cost of ventilation and cooling systems can be reduced a lot.
