The article presents the results of studies on the effect of commercial food on the processes of free radical oxidation of lipids in the body of cats with urinary tract pathology. It has been found that the concentration of diene conjugates in the blood serum of sick animals increases significantly by 15.1 - 36.7% relative to healthy ones. The MDA content in the blood serum of healthy animals was 6.05 ± 0.28 nmol / g. In animals with urolithiasis, this indicator increased by about 2 times. When feeding with commercial food and homemade food, LPO processes normalize, which is most pronounced on the 21st day. The average activity of catalase in the blood serum of sick animals was increased from 30.6% to 40.2% relative to healthy ones (15.15 ± 0.61 ?mol / ml). After feeding with therapeutic and prophylactic fodders, by the 7th day, the catalase activity did not significantly decrease compared to the initial level, but remained higher than in control animals by 19.6% - 37.1%. On the 14th day, the catalase activity did not change significantly compared with the 7th day and was higher than the control values by 21.5% - 27.5%.
For the study, two groups of cats were formed at the age of 1 to 4 years in the amount of 6 animals each. According to research it was found that cats are more likely to suffer from urolithiasis than cats. At the same time, in the percentage ratio of the difference between castrated and non-castrated cats with urolithiasis, it was not expressed explicitly (29.01% and 31.49%, respectively, of the total number of sick animals). The highest percentage of incidence of urolithiasis was recorded in sterilized cats (23.98%). It was found that after feeding animals with commercial feed in the studied time there is a decrease in the number of struvites in the urine. The greatest decrease in struvite count was determined after feeding cats with Hills prescription diet urinary care c/d multicare. There is also a change in the acid-base state of urine when feeding Hills prescription diet urinary care c/d multicare by 10.9% and 13.1% and Hills prescription diet urinary care c/d multicare by 12.3% and 9.5% to 3 and 6 months, respectively. Significant differences in urine density after feeding with commercial feed and homemade food have not been established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
