PRACTICAL SUBSTANTIATION OF THE EFFECTIVENESS OF OPERATIVE METHODS OF TREATMENT OF RENNET DISLOCATION

Abstract

Increased milk potential of animals often leads to disturbance of substance metabolism and appearance of various diseases. Displacement of rennet causes serious economic damage to livestock farms, including reduction of milk productivity, culling, attrition of sick animals, organization of preventive measures and treatment costs. Moreover, after treatment it is impossible to exclude completely the recurrence of this pathology, in some animals we can diagnose the displacement of the abomasum again. In this regard, the aim of our research was to study the comparative effectiveness of operative methods of treatment of rennet displacement. Two groups of 10 cows each with rennet displacement of different age were formed for the research. As a result of the conducted researches, we found out that application of the method of operative suturing of the rennet to the abdominal wall, in the area of the right hungry fossa, is the most effective and reduces the time of recovery of milk productivity in the cow, as well as minimizes the appearance of recurrences of the disease. Treatment efficiency was 80% in the 1st experimental group and 100% in the 2nd experimental group. Recovery in the 1st experimental group came on average on 12,2±1,4 days, in the 2nd experimental group on average on 10,3±1,2 days. The economic efficiency of using the puncture method of treatment, taking into account postoperative therapy amounted to 49,1 rubles, and the economic efficiency of using the surgical method of treatment by suturing the rennet through the right gluteal fossa, taking into account postoperative therapy amounted to 49,3 rubles.
