Фрагмент работы

This report will be about Holstein cows, which include:
Origin of the Breed;
Americans Build Their Own Breed;
Characteristics of Holsteins and another chapters.
The breed ir very important not only in United States, either in New Zealand, Holland and in another countries of Europe.
Holstein black-and-white cows are with a great productive, an average Holstein cow in the United States produces about 26,500 pounds of milk per year. This is about 12,000 kg of milk per year. European Holstein cows tend to average 7,000 – 8,000 litres per year. You can see the difference.
Basically farmers, who lives in Latvia, cannot produce 12,000 kg of milk per year with Holstein breed in Latvia. Their cows can achieve European’s level.
My report’s most important purpose is to initiate another students with my profession of future.
My report’s most important task is to initiate another students with Holstein’s cow breed.
The Holstein cow originated in Europe. The major historical development of this breed occurred in what is now the Netherlands and more specifically in the two northern provinces of North Holland and Friesland which lay on either side of the Zuider Zee. The original stock were the black animals and white animals of the Batavians and Friesians, migrant European tribes who settled in the Rhine Delta region about 2,000 years ago.
The Holstein breed has one of the biggest gene pools world – wide and thus genetic progress has been faster than in other dairy breeds.
For many years, Holsteins were bred and strictly culled to obtain animals which would make best use of grass, the area's most abundant resource. The intermingling of these animals evolved into an efficient, high-producing black-and-white dairy cow.
The Holstein is now the most common breed of dairy cattle around the world – in the United States Holsteins constitute 90% of the 10 million dairy cow population. The Holstein's most outstanding characteristic is its combination of a high volume of milk production at an acceptable milk fat percentage.
Although the ancestral Holstein and Friesian herds are merged in parts of the world, breeding records are often kept by the industry to indicate the percentage of Holstein and Friesian ancestry in a particular animal.…
