Hematological Blood Values of Store Pigs According to the Automated Analysis Data

Pig breeding, as an independent livestock sector in Russia, has been developing steadily since 2008. This was facilitated by the adoption of the agricultural development program, which assumed an increase in state support for the agro-industrial complex. However, the intensification of pork production places high demands on the quality of livestock, which necessitates the use of breeds, types and lines that can withstand the loads of modern industrial technology without reducing productivity.

Selection of parent pig pairs by resistency indexes

In 2015, 18 sows of a large white breed, 72 piglets obtained from these sows and 18 boars from another farm, whose sperm was taken for fertilization of sows, were examined in the Kislov individual entrepreneur farm by resistance indicators. On the basis of blood indices, a new selection index of resistance was developed, which includes bactericidal, complementary and lysozyme activity of blood serum, phagocytic activity and index, taking into account the coefficients of heritability of each feature. Parent pairs were selected for resistance indices, which had a positive effect.

Methods of estimation and selection of pigs by resistance indices

The article deals with the study carried out on the sows of a large white breed and their offsprings. It has been established that the sow resistance is positively associated with their reproductive qualities. A new breeding resistance index is developed. Selecting of one-month old replacement gilts of a large white breed by the new methods of resistance has had a positive result.
