Economic efficiency of castration of boars using different methods on the background of immunocorrection under the conditions of industrial technology

Abstract

The article presents the results of determining the economic efficiency of the use of two immunocorrectors — thymogen and mikovit (ribav) during castration of boars in industrial technology.The studies were performed on 49 boars (aged 5 months), divided into seven groups — two control and five experimental ones (n=7 in each).All animals were castrated: in the 1st control, 1st, 2nd, 3rd and 4th experimental groups — using open method; in the 2nd control and the 5th experimental groups — using closed method. Preoperative support was carried out according to the methodology used to the farm.The boars of the experimental groups were additionally treated with immunomodulators: in the first one — with thymogen (five-day course before surgery), in the second one — with mycovit (ribav), according to the scheme of the first group with local application after surgery, in the third — according to the scheme of the first group, but after the surgery; in the 4th and 5th — only with the working solution of mikovit (ribav) according to the method of the 2nd experimental group.The economic effect of the developed schemes was defined as the difference between the damage prevented as a result of veterinary measures and veterinary costs, taking into account the additional cost obtained by increasing the quantity of manufactured products and improving their quality. As an additional method, the total index of the effectiveness of veterinary measures was used, which was calculated by multiplying the economic damage by veterinary costs (per animal in each group) and then dividing the resulting number by their minimum multiplication.It was shown that the inclusion of thymogen at a dose of 100 μg/cm3 into the basic regimen of intramuscular injections with a five-day course after surgery using an open castration method or irrigation of the wound surface according to the above scheme with the solution of mycovit (ribav) can significantly increase the economic effect of veterinary measures. In the conditions of industrial pig breeding (taking into account the higher manufacturability of the application), preference should be given to thymogen.
