INDICATORS OF MINERAL AND VITAMIN METABOLISMS IN SOWS WITH INFLAMMATORY PROCESSES IN REPRODUCTIVE ORGANS
The article presents the results of the study of mineral and vitamin metabolisms in sows with inflammatory processes in reproductive organs, and the risk of their development at various stages of the reproductive cycle. The researches were carried out in a specialized pig-breeding farm in the Voronezh region on 25 sows of cross-breed of large white breed and Landrace, which were divided into 3 groups. The first group (n=7) is represented by sows, which remained clinically healthy after farrowing and did not have hidden endometritis at the excitement stage of the sexual cycle. The second group (n=9) included sows with a normal course of the postpartum period and the presence of hidden endometritis in the excitement stage of the sexual cycle. The third group (n=9) consisted of sows with a post-parturient complication and latent endometritis. In order to evaluate the mineral metabolism in each group the blood samples were taken for laboratory tests 10 days before farrowing, and before weaning piglets from sows. It was found out that 10 days before the expected farrowing in sows of all experimental groups the indices of mineral and vitamin metabolism were within the lower limit of the normal, except for magnesium. Before weaning piglets in clinically healthy sows and in animals with latent endometritis the indicators of mineral and vitamin metabolism did not change and were within the normal range. During this period, the amount of magnesium in all animals increased to the lower limit of the normal. The changes in the mineral and vitamin status of sows with inflammatory processes in reproductive organs and the risk of their development can be used as additional diagnostic tests.
