Chapter 8 Breeding New Cattle Breeds (Happy New Year’s Day, Happy 2022)

In 1999, the average annual milk production of Holstein cattle in the Netherlands was 8,016 kilograms, with a milk fat rate of 4.\n4% 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 an American cow named Cow, which produced 30,833 kilograms of milk after two milkings in 365 days in 1997. So far, more than 37 Holstein cows in the United States have an annual milk production of more than 18,000 kilograms. The highest lifetime milk production record is a cow in California, 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 imported from abroad with 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 «out.

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 a major agricultural country like the United States, where the cost of pasture and feed is much lower than in China. The breeding method is scientific, clustered, and large-scale. The cost of breeding is also lower than that of domestic free-range farming.

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 for the dairy industry, but also for 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 the [Shennongjiao Space] and purchased many high-tech instruments.

The newly added [auxiliary space] after the upgrade of [Shennongjiao Space] is the place where her research is produced.

Twenty times the speed of time gave her a lot of room for use. Coupled with the [Gene Optimization] ability of [Shennongjiao Space], Wu Siyuan believed that she would 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 the 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. The breed is now raised in most cattle-raising countries in the world.

Angus cattle are smaller in size, and their coats are mostly 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, the waist and spine are plump, the body is deep and wide and cylindrical, and the limbs are short and straight, which are typical characteristics of beef cattle.

Angus cattle mature early and are easy to mate, have short calving intervals, good calving continuity, and rarely have dystocia. It has strong disease resistance and cold resistance, 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%. It has a gentle temperament and is 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, with waxy or white horns.

Good adaptability, drought resistance, cold resistance and heat resistance. 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 are tall and muscular and are a large breed of beef cattle. The coat on the whole body is milky white or light milky yellow, and the skin is fleshy red. The forehead is wide, the face is short, the corners are round and long, stretching forward, the neck is medium long, the chest is deep and the ribs are round, the back and waist are deep and wide, the buttocks are plump, the whole body is barrel-shaped, the limbs are thick, the hind leg muscles are very developed, and have the characteristics of double muscles.

Charolais cattle are resistant to rough feeding, cold and heat. It grows rapidly in the early stage and has a high lean meat rate. The weight of adult bulls is 900~1200 kg and that of cows is 670~790 kg. The dressing rate is 65%~70%, the clean meat rate is 55%, and the daily weight gain before 15 months of age is very high.

In addition, high-quality beef cattle breeds such as Limousin cattle, Belgian Blue cattle, Japanese Wagyu cattle, 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 breeding 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] and let them reproduce and grow naturally without doing anything, 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 comes with [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.
