In 1999, the average annual milk production of Holstein cattle in the Netherlands was 8016 kilograms, with a milk fat rate of 4.4% and a milk protein rate of 3.42%.
The average milk production of Holstein cattle registered in the United States in 2000 was 9,777 kilograms, with a milk fat rate of 3.66% and a milk protein rate of 3.23%.
The world's highest individual record is set by a cow in the United States. In 1997, it produced 30,833 kilograms of milk after two milkings in 365 days. To date, more than 37 Holstein cows in the United States have an annual milk production of more than 18,000 kilograms, setting a new record.
The record for the highest lifetime milk production is a cow in California, USA, which produced 189,000 kilograms of milk in 4,796 days of lactation.
China's [Holstein cattle], also called Friesian cows, are a breed formed by crossing various types of Holstein cattle introduced from abroad and Chinese cattle, and after a long period of selective breeding. This is also the only breed in my country. Dairy breeds.
Compared with the huge output of foreign dairy cows, my country's Friesian cows have a low milk fat rate and are intolerant to rough feeding. Under good feed conditions and feeding management, the average milk production in 305 days can reach 6500-7500 kg, with a milk fat rate of 3.5 About %.
The unit milk production is far inferior to that of others. That is to say, under the same breeding conditions, the cost of domestic milk production is much higher than that of foreign countries.
Not to mention that in a major agricultural country like the United States, the cost of pasture and feed is much lower than in China. The breeding adopts scientific breeding methods, clustering and large-scale breeding, and the breeding cost is also lower than that of domestic free-range farming.<
/p>
Not to mention the various nutritional indicators of milk.
To sum up, the cost of domestic milk is far higher than that of foreign countries, and the quality is not as good as others.
Only with good cows can we have good milk.
This is also the reason why China imports a large number of breeding cattle every year!
We have to breed domestic dairy cows!
In fact, this is not only true in the dairy industry, but also in the chicken and pig industries.
Especially the era in which the male protagonist Ju An is still using Nokia and Motorola!
Wu Siyuan came from later generations and knew that China has been making progress in this aspect, but there was too much work that was lacking before, and it took time to catch up.
Wu Siyuan has a golden finger and is willing to shorten this period of time for the country in order to increase his influence in the industry.
………………………………………………………………………………………………………………………………
………
After Wu Siyuan bought the ranch, he recruited a few honest and dedicated cowboys locally, and through them, purchased 5,000 [American Holstein cattle].
In the American dairy industry, the number of [American Holstein cattle] is the highest, reaching 94%.
As long as they are not exported and are only circulated locally, Wu Siyuan can easily buy these [American Holstein cattle] as much as he wants.
Then Wu Siyuan quietly sent dozens of the best quality bulls and cows into the [Shennongjiao Space].
At the same time, Wu Siyuan frequently traveled between China and other countries, using some secret means to send many high-quality cattle breeds from various countries into the [Shennongjiao Space].
He Youman has established his own biological research institute in [Shennongjiao Space] and purchased many high-tech instruments.
The newly added [annexed space] after the upgrade of [Shennongjiao Space] is her research place.
Twenty times the flow rate of time gives her a lot of room for use. Coupled with the [Gene Optimization] capability of [Shennongjiao Space], Wu Siyuan believes that she will be able to bring results to Wu Siyuan soon. In addition to dairy cows, Wu Siyuan also purchased many high-quality beef cattle in the United States through purchased pastures.
For example, Angus cattle.
Angus cattle are one of the oldest beef cattle breeds in the UK. They originate from Aberdeen, Kincardine and Angus counties in northern Scotland. They are the main cattle breed in the United States, Canada, the United Kingdom, Argentina and New Zealand.
This breed is now raised in most cattle-raising countries in the world.
Angus cattle are smaller in size, and their coats are mostly all black and shiny. A few individuals have white spots on their abdomen, navel and breasts. The head is small and square, without horns, the neck is medium long, the back and waist are straight, and the waist and spine are plump.
, the body is deep and wide and cylindrical, the limbs are short and straight, with typical characteristics of beef cattle.
Angus cattle are early-maturing and easy to mate, have short calving intervals, good succession, and rarely dystocia. They have strong disease resistance and cold tolerance, but poor heat resistance.
Angus cattle are small and early-maturing breeds. The weight of bulls is 700-750 kg, and the weight of cows is 600-700 kg. The daily weight gain is 800-1000 grams. They have good meat production performance. Generally, the slaughter rate is 60%-65% and the clean meat rate is 48%.
~52%. Mild in temperament and easy to manage, it is recognized as the best maternal line in the international beef cattle hybrid system.
There are also Herford cattle, which are also one of the oldest beef cattle breeds in the UK. They originate from Herford County in the west of the island of England. They are divided into horned and hornless horns, with waxy or white horns.
It has good adaptability and is resistant to drought, cold and heat. The weight of adult bulls is 900-1100 kg, and that of cows is 520-620 kg. The daily weight gain exceeds 1000 grams. The slaughter rate after fattening can reach 67%, up to 70%, and the clean meat rate is 60%. Wu Siyuan will not miss the world-recognized economic hybrid male parent - Charolais cattle.
Charolais cattle are the largest beef cattle breed in Europe. They originate from the Charolais and Nièvre regions in central France. They are one of the modern large-scale beef breeds.
Charolais cattle have tall bodies and well-developed muscles, and are a large breed of beef cattle. They have milky white or light milky yellow hair all over their bodies, and fleshy red skin. They have a wide forehead, short face, long rounded horns, stretching forward, a medium-long neck, deep chest, and round ribs.
The back and waist are deep and wide, the buttocks are plump, the whole body is barrel-shaped, the limbs are thick, and the hind leg muscles are very developed, with the characteristics of double muscles.
Charolais cattle are resistant to rough feeding, cold and heat. They grow rapidly in the early stage and have a high lean meat rate. The weight of adult bulls is 900~1200 kg, and that of cows is 670~790 kg. The slaughter rate is 65%~70%, and the clean meat rate is 55%.
%, the daily weight gain before 15 months of age is very high.
In addition, high-quality beef breeds such as Limousin cattle, Belgian Blue cattle, Japanese Wagyu, Piedmont cattle, Simmental cattle, etc. were all collected by Wu Siyuan into the [Shennongjiao Space] and handed over to He Youman for research.
.
The process of cultivating new livestock breeds is often time-consuming, labor-intensive and a test of luck.
But in [Shennongjiao Space], none of this is a problem.
To be honest, if you throw a batch of cattle into the [Shennongjiao Space] without doing anything and let them reproduce and grow naturally, after a period of time, Wu Siyuan will get a batch of cattle whose quality is far superior to the previous generation.
Because [Shennongjiao Space] itself has [Gene Optimization], and the air is rich in spiritual energy, plants can be transformed inside, and this change can be inherited and weakened from generation to generation.
But Wu Siyuan still wants to select the best from the best and breed better cattle breeds.
