Boar's cryptorchidism in the conditions of Pig-breeding complex

The aim of research work was to conduct a comprehensive analysis of the prevalence of cryptorchidism in young boars in the conditions of industrial pig-breeding complex. To achieve this goal we have analysed documents veterinary accounting and reporting, as well as the General clinical examination of animals, found that the creep-torism diagnosed of 32.00% of newly arrived pigs to the rearing site, and medium cyclic frequency of registration varies from 2.0% to 4.0%. Records of the seasons showed that in the preparation of young pigs from the farrowing in autumn to La cryptorchid is 42,93% (27799 pigs), in the winter of 32.70% (21190 pigs) in the summer of 13.70% (8877 pigs), in the spring of 10.70% (6934 pigs). Analysis of the studied pathology in the farrowing in identifying etiological factors has allowed to establish that the greatest number of sick animals is recorded in a litter of gilts at the first farrowing - 27,70% (3412 pigs) in young sows at the second farrowing - 10,80% (1331 pigs), and sows the sixth - 19,80% (2440 pigs) and the seventh farrowing - 22,50% (2773 pigs), in addition, as the number of animals in the litter sows decreases, there is a decrease in the rate of registration of accounted andrological pathologies in piglets postnatal period, i.e. the following trend is established: 12 piglets - 19,80% (2440 pigs), 10 piglets - 16,20% (1995pigs), 7 piglets - 14,20% (749 pigs).
