EFFECTIVENESS OF TREATMENT OF SPONTANEOUS MIXED COURSE OF ISOSPOROSIS AND CRYPTOSPORIDIOSIS IN PIGLETS

Abstract

Intestinal coccidiosis, in particular isosporosis and cryptosporidiosis, lead to significant economic losses in the global pig industry. Piglets become infected immediately after birth through ingestion of sporulating oocysts from previously infected litter, as sows are considered a secondary source of infection for them. Proper housing and hygiene, which reduce the accumulation of oocysts in the environment and exposure of piglets to sporulation oocysts, are key to disease prevention. The goal of the work. To determine the effectiveness of eimeriostatics for the mixed course of isosporosis and cryptosporidiosis in piglets. The effectiveness of the drugs was determined on 14-day-old piglets of the breed ''Velika Bila''. The piglets of the first experimental group were given the drug Turil 5%, the second experimental group - Brovitacoccid, the third experimental group - Amprolev-plus." The dynamics of the infestation of piglets with isospores and cryptosporidia after the use of the drugs and their effectiveness were determined on the 7th, 14th and 28th days by counting the number of oocysts in 10 fields of view of the microscope according to the method of N.P. Orlova (1956). After treatment of piglets with the drug Turil 5% on the 14th day, the release of I. suis decreased to 3.9 ± 0.1 oocysts, and on the 28th day they were not recorded, while on the 28st day C. suis was at the level 7.4±0.2 oocysts in 10 fields of view of the microscope. When using Brovitacoccide on the 14th and 28th days, I. suis was not recorded, and the infestation of piglets by C. suis was 3.5±0.2 oocysts. The best indicators regarding the reduction of oocyst excretion were obtained in the group of piglets treated with the drug Amprolev-plus. On the 14th day, only the release of I. suis oocysts was recorded (5.1±0.1 oocysts in 10 fields of view of the microscope), and on the 28th day, the release of C. suis and I. suis oocysts was not recorded. On the 14th day, the effectiveness of Brovitacoccsid against I. suis and Amprolev-plus against C. suis was 100%, and already on the 28th day, 100% effectiveness of Amprolev-plus also showed against I. suis.
