Chapter 255 Breeding a New Breed of Cattle (Happy New Year's Day, Happy 2022)
1999年荷兰全国荷斯坦牛平均年产奶量为8016千克，乳脂率为4．4%、乳蛋白率为3.42%。

The average milk yield of Holstein cattle registered in the United States in 2000 reached 9777 kg, with a milk fat rate of 3.66% and a milk protein rate of 3.23%.

The world's highest individual record is a cow named American, who milked twice in 1997 days in 365, and the milk production was as high as 30833 kg.So far, more than 37 Holstein cows in the United States have produced more than 18000 kilograms of milk per year. The highest lifetime milk production record is a cow in California, which produced a total of 4796 kilograms of milk within 189000 days of lactation.

China's "Holstein cattle", also known as black-and-white cows, is a breed formed by crossing various types of Holstein cattle imported from abroad with Chinese cattle, and after a long period of selective breeding, it is also the only one in my country. Dairy breeds.

Compared with the huge output of foreign dairy cows, my country's black-and-white dairy cows have a low milk fat rate and are not resistant to rough feeding. Under good feed conditions and feeding management, the average milk production in 305 days can reach 6500-7500 kg, and the milk fat rate is 3.5 %about.

The unit milk production is far inferior to that of others, that is to say, under the same breeding conditions, the production cost of domestic milk is much higher than that of foreign countries.

Not to mention a large agricultural country like the United States, where the cost of forage and feed is much lower than that in China, and the breeding method is scientific, clustered, and large-scale farming, and the cost of breeding is also lower than that of domestic scattered.

Not to mention the various nutritional indicators of milk.

Taken together, the cost of domestic milk far exceeds that of foreign countries, and the quality is not as good as others.

Only with good cows can there be good milk.

This is also the reason why a large number of breeding cattle are imported every year in China!

We have to breed domestic cows!

In fact, this is not only the case in the dairy industry, but also in the chicken and pig industries.

Especially in the era that the male protagonist Ju An is in now, the era when Nokia and Motorola are still used!

Wu Siyuan came from a later life and knew that China has been making progress in this area, but there was too much homework before, and it took time to catch up.

And Wu Siyuan has a golden finger, and he is willing to shorten this period of time for the country, but also 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 [-] head of [American Holstein cattle].

In the dairy industry in the United States, the stock of [American Holstein cattle] is the highest, reaching as high as [-]%.

As long as it is not exported but only circulated locally, Wu Siyuan can easily buy these [American Holstein cattle] as much as he wants.

Then Wu Siyuan quietly sent dozens of bulls and cows of the best quality into [Shennongjiao space].

At the same time, Wu Siyuan frequently travels to and from China or other countries, using some secret means to send many high-quality cattle breeds from various countries to [Shennongjiao Space].

He Youman has established his own biological research institute in [Shennongjiao Space], and has purchased a lot of sophisticated instruments.

And the newly added [Subsidiary Space] after the upgrade of [Shennongjiao Space] is her research place.

Twenty times the speed of time, giving her a lot of space to use things, coupled with the [Shen Nong Corner Space]'s own [Gene Optimization] ability, Wu Siyuan believes that she will soon bring results to Wu Siyuan.

In addition to dairy cows, Wu Siyuan also bought many high-quality beef cattle in the United States through the purchased ranch.

For example, Angus cattle.

Angus cattle are one of the oldest beef cattle breeds in the United Kingdom. They are native to Aberdeen, Kincardine and Angus County in northern Scotland. They are the main cattle breeds 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 small in size, and their coat is mostly black and shiny. A few individuals have white spots on the abdomen, umbilicus and breasts.The head is small and square, without horns, the neck is medium and long, the back and waist are straight, the waist is plump, the body is deep and wide and cylindrical, and the limbs are short and straight, with typical characteristics of beef cattle.

Angus cattle are precocious and easy to mate, with short calving intervals, good continuous production, and rarely dystocia.Strong disease resistance, cold resistance, but poor heat resistance.

Angus cattle are small early-maturing breeds. Bulls weigh 700-750 kg, cows 600-700 kg, and gain 800-1000 grams per day. The meat production performance is good. The general slaughter rate is 60%-65%, and the net meat rate is 48%. ~52%.Mild temperament and easy to manage, it is recognized as the best female line in the international beef cattle hybrid system.

There are also Hereford cattle. Hereford cattle are also one of the oldest beef cattle breeds in the UK. They are native to Hereford County in the west of the Isle of England. They are divided into horned and hornless horns.

Good adaptability, drought resistance, cold resistance and heat resistance.Adult bulls weigh 900-1100 kg, cows 520-620 kg, with a daily gain of more than 1000 grams. After fattening, the slaughter rate can reach 67%, the highest is 70%, and the net meat rate is 60%.

Wu Siyuan will not miss the world-recognized economic hybrid male parent - Charolais cattle.

Charolais is the largest beef cattle breed in Europe. It originated in the Charolais and Nievres regions in central France. It is one of the modern large-scale meat breeding breeds.

Charolais cattle are tall and muscular, belonging to a large breed of beef cattle.The whole body is creamy white or light creamy yellow in coat, and the skin is fleshy red.Wide forehead, short face, round and long horns, extending forward, medium-length neck, deep chest and round ribs, deep and wide back and waist, plump buttocks, barrel-shaped body, thick limbs, well-developed hind legs, with double muscle characteristics.

Charolais cattle are resistant to rough feeding, cold and heat.The early growth is rapid, the lean meat rate is high, the weight of adult bulls is 900-1200 kg, and the weight of cows is 670-790 kg.The slaughter rate is 65%~70%, the net meat rate is 55%, and the daily gain before 15 months is very high.

In addition, Limu cattle, Belgian blue cattle, Japanese Wagyu, Piedmontese cattle, Simmental cattle and other high-quality beef cattle breeds were all collected by Wu Siyuan in [Shennongjiao Space] and handed over to He Youman for research .

The breeding process of new livestock breeds is often time-consuming, labor-intensive and a test of luck.

But in [Shennongjiao Space], all this is not a problem.

To be honest, if you throw a batch of cattle into [Shennongjiao Space], you don’t need to do anything, let them multiply 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] has its own [Gene Optimization], and the air is rich in aura, all plants in it can undergo a radical change, and this change will be passed down from generation to generation.

But Wu Siyuan still wants to select the best from the best and breed better cattle breeds.

　Good luck to my readers in 2022.
