Characteristics of the breed of pigs Dyurok


In the meat and bacon direction of the pig breeding, the Duroc breed has become very popular because of its tender marble meat, precociousness, and high productivity. As early as the 19th century, a modern species of these animals appeared as a result of crossing the pigs from New York and New Jersey. Pigs from America have spread around the world. Most of the representatives of this species concentrated on the American continent, in Europe and China.

Afro-American background

This type of pigs appeared as a result of breeding work with a huge variety of genetic material of pigs, imported from different countries to North America. Duroc is a breed of pigs, the base for the breeding of which became animals from African Guinea. They differed in large size, red color and short bristles.

Initially, they were crossed with pigs from Portugal and Spain. As a result of this breeding work, pigs with characteristic breed traits were originally obtained. It was on their basis that breeding work began to be carried out to improve the breed on a planned basis. In America, two lines were developed in parallel: Duroc and Jersey.

Jersey piglets grew and developed rather slowly, but in adulthood, these animals were large, rough powerful skeleton. Dyuroki of those times was characterized by thin bones, high fleshy. In addition, their main advantage was ripening. By combining the best qualities of these pig species, breeders received a new breed, which was registered in 1883 under the name "Duroc".

Appearance and characteristics

Due to the long-term work of breeders, initially greasy pork breeds from Africa, Spain, Portugal, England, as a result of crossing, acquired more and more meat, bacon traits. This met the needs of most consumers.

At the moment, the description of the Duroc breed has the following characteristics:

  • large oblong body up to 180 cm long;
  • live weight of adults from 240 to 350 kg depending on gender;
  • a relatively small head with forward-directed ears that have curved tips;
  • back in the form of a slightly arched arc;
  • body color of various shades of red;
  • massive high legs with well developed muscles in the field of ham.

With proper fattening, such an American gains weight over 100 kg in six months of life. In this case, the average weight gain per day ranges from 750 to 950 g. After slaughtering an adult animal, up to 70% of meat by weight of pork carcass is obtained. The sebaceous layer above the spine has a thickness of 12-18 mm.

Representatives of the Duroc breed in the warm season need to stay outdoors.

The advantages and disadvantages of the breed

Despite the breeders' best efforts over the years, the Duroc pigs, apart from the advantages, also have weak points.

The uniformity of the carcass, the highest quality of meat products after slaughter pay back the costs of raising animals. In addition, this pig breed is characterized by a high percentage of meat production. Duroki perfectly interbreed with such representatives of pig breeds as landrace, large white pigs. Metis are distinguished by rapid growth, endurance, and resistance to environmental pathogens.

On the other hand, the negative features of the Duroc breed are in the low fertility of animals (7-10 young), their particular demands on the protein diet. In addition, breeders are worried about pathological susceptibility to atrophic rhinitis, incorrect setting of the legs. The most favorable environment for growth, development and reproduction of durok are conditions of a dry warm climate. For more prolific animals, see the article "Growing Vietnamese low-fat pigs."

Active hunting of gilts lasts about 48 hours, but the boar is more likely to fertilize the female only on the second day.

Therefore, it is recommended that the first half of the hunting time not bother pigs, and in the remaining period to increase the likelihood of fertilization of the sow twice to carry out the mating with an interval of 12 hours. In industrial environments, two boars are often used for this.

In order to obtain high-quality offspring, it is necessary to ensure the mobility and good nutrition of the pregnant pig. It is recommended to provide her with the opportunity to stay in the open area for a long time. Despite the well-developed maternal instinct in sows of the Duroc breed and the high survival rate of piglets, from the first days of life, the young are introduced to feed. At the same time, iron-containing products, vitamins, and special additives should be added to the feed.

For farrowing you need to create conditions of warmth, dryness and comfort. The temperature inside the pigsty should not fall below 25 degrees Celsius. Walls and floors should be covered with thick dry bedding made from straw or sawdust.

Typical diseases of pork breed Duroc

These pigs are distinguished by good immunity and resistance to most diseases characteristic of representatives of other pig species. Draft, sudden changes in temperature, cold, overheating as a result of exposure to the sun often lead to rhinitis, rhinitis.

Infection is transmitted from one individual to another. If pathological manifestations are detected inside the herd, it is required to isolate the diseased mumps. After that, therapeutic measures are taken, which consist in washing the pig nose with a weak solution of potassium permanganate and the internal administration of antibiotics. In this case, drugs must be prescribed by a veterinarian.
