The extensive path for development in the country in the
twentieth century caused low competitiveness of
Russian pig production. The productivity of domestic
pig production was significantly lower than in Europe,
US, Canada and China. Feed costs per 1 kg of gain were
2-3 times higher with a low yield of piglets from a sow
per year: 14-16 with an average European 25-27 heads.
The country did not have enough meat; as a result, a
significant amount of meat products was imported to
Russia. Restrictions on imports in connection to the
imposition of embargoes contributed to the increase in
demand for domestic products and opened new
opportunities for Russian producers. One way to
increase the production of pork is to use pigs with a high
genetic potential for productivity, imported for breeding
from Canada and Europe. Based on the conducted
studies, it has been established that pigs of foreign
breeding have high reproductive qualities, which proves
the expediency of their application in commercial pig
production to increase the efficiency of the industry
development and reduce the import of pedigree
youngsters from abroad. The implementation of two
breed gilts will help increase productivity in the
industrial pig production
In recent years, many pigs of specialized breeds,
characterized by increased meat qualities, have been
brought to Russia from Canada and a number of
European countries. The article presents the results of
the assessment of slaughter and meat qualities of pigs
of different genotypes. Danish pig meat was used as
research objects: purebred landrace (CHL), benthic
hybrid Landrasx yorkshire (LxY), three-breed hybrid
landrace hyorkshire x dyurok (LxXxD), removed from
control fattening, and developed prototypes of delicacy
products. The commission evaluation of meat and
broth showed that the boiled meat from the three breed
animals received the highest score, and the quality of
the broth significantly exceeded the samples of
purebred landrace and two-breed animals. As a result
of the tasting evaluation of the Voronezh ham, it was
established that the samples of meat from threebreeded
pigs, in comparison with the samples from
purebred meat, show the most pronounced flavor,
aroma and soft consistency
A comprehensive assessment was made of the own productivity of repair pigs and the quality of sperm production of boars of different breeds. Imported boars and mumps had thin bacon 13-15 mm, high early ripeness 145-153 days and a depth of "muscular eye" 53-53.9 mm, indicating an increase in the content of lean meat in the carcass. However, the length of the trunk of the animals was 120 cm, which corresponds to the first class of the instructions for bonitation. There was a significant difference in the growth rate of repair young (about 300 g), which indicates the individual characteristics of animals and the possibility of selecting the best animals for reproduction of the herd. Assessment of pigs by phenotype is an important element of breeding work on complexes. It is established that the quality of sperm production is affected both by the breed and the season of the year: the volume of ejaculate and the concentration of spermatozoa in all breeds are greatest in the autumn-winter period. Boars Maxgro were distinguished by an increased volume of ejaculate, but a low concentration of sperm compared to a large white breed and landrace. During the year, the greatest fluctuations in sperm concentration in large white breed boars were observed ± 133 million / ml, the smallest - Landrace ± 29 million / ml, which contributes to the uniform production of semen doses for insemination
