As a new Myrhorod breed, the work of breeders from Poltava was approved in 1940. As the main population groups for breeding, females of the Ukrainian short-haired pigs were taken, and males of the Berkshire breed and thawvors were taken as males. The works of breeders were led by Professor AF Bondarenko.
Pigs of the Myrhorod breed are fairly easy to recognize by external signs. Firstly, it is a pig of a unique suit – a mixture of black and white, although for the sake of justice it should be noted that there are individuals with absolutely black and black-red coloration. In length, the body of the boars of Mirgorod breed can reach 180 centimeters, while females reach a maximum of 170 centimeters in length. One of the main features of the breed is the girth of the trunk behind the shoulder blades, this value is practically equal to the length of the body or 6-8 centimeters less than the body length of the individual.
The very body of the pigs of the Myrhorod breed is quite wide and massive. The head is not large, but rather of medium size with a slightly concave inward profile. The ears of the Mirgorod pigs are inherited from the parental form, they are small sticking up, sometimes there are individuals with slightly saggy ears. Legs of representatives of Mirgorod breed of medium height, hams large, well developed. The skin of animals is smooth, without wrinkles, covered with a uniformly thick medium length of stubble.
In the period when it is possible to slaughter, the pigs of Mirgorod breed have an average weight of about 220 kilograms (adult boars reach a greater weight of up to 330 kilograms). Uterus of the Myrhorod breed is very prolific, at a time the uterus can produce 10 or even more piglets, which are born on average about 1.2 kilograms, and after six months weigh up to a centner.
The average weight gain of piglets of Mirgorod breed with rational feeding and care is 670-700 grams per day. After slaughtering in the carcass, about 54-55% of meat and 37-38% is fat. Bumper has a thickness of about 28 millimeters. The fat of the Myrhorod breed of pigs is very tasty and is considered to be the standard standard.
It is believed that the Myrhorod breed of pigs is one of the most common breeds in Ukraine, this breed is especially widespread in the central (Poltava, Cherkasy) and northern regions (Zhytomyr, Sumy, Rovenskaya). The Myrhorod breed is also very widespread in the neighboring Belarus. For Russia, this breed is not typical, except for some southern regions of the country. However, by the mid-1990s, the number of pigs of the Myrhorod breed in Ukraine was significantly reduced, as the breed began to lose its productive qualities to other breeds.
As a support for the breed, a number of crossings were conducted with the pigs of landrace, hampshire, thyme and large white pigs. Without carrying out this selection work, the Myrhorod breed would completely disappear by the beginning of the 2000s. As shown by modern studies on the basis of the Myrhorod breed, it is entirely possible to create new lines with the results of different productivity.
Among the positive features of the Myrhorod breed, its unpretentiousness to fodder and its adaptability to pasture content, which is characteristic of the forest-steppe zone, should be noted. Also, this breed is popular with pig producers due to the fact that very quickly gain weight and save fat.
The minus of the rock lies in the relatively high percentage of fat content in the carcass. The second disadvantage is the heat-loving nature of the rock. Pigs of Myrhorod breed badly tolerate the cold and in unheated pigsties in winter greatly reduce daily weight gain.
