Сравнительная оценка эффективности минерально-витаминных премиксов при выращивании ремонтных свинок

World experience has proved that the major factor of increasing reproductive qualities when growing replacement gilts is the use of complete mixed feeds and transition from mixed fodders confirmed by the State Standard to address individual formulas. At carrying out of comparative evaluation of mineral and vitamin premixes the best result was achieved when using complete mixed feed with the developed address formula along with introduction of iodine microelement in the form of injections of iodide starch. It proves to be true by increase by 19% of daily average gains of replacement gilts during the period of their growth. Livy index increases by 1.8 units, the amount of embryos by 27%, the amount of yellow bodies by 11%. The weight of ovaries increases by 36%, and embryonic death rate decreases by 11%. To obtain high productive and reproductive qualities of replacement gilts it is necessary to use complete mixed feeds, and iodine should be introduced twice in the form of injections of iodide starch solution. So, the first doze of iodine makes 12.7 mg/head at live weight of 40 kg, the second doze 24.2 mg/head at live weight of 70 kg.
