Effect of «Erakond» Preparation on Increase of Colostrum Immune Qualities of Cows and Immune System of Calves
Abstract
As a result of researches the method of biological effect on immune competence of colostrums and natural resistance of the young cattle was developed. The perfects doze of immune stimulator “Erakond” is determined for cows and first-calve heifers - 7,5 and 6,5 mg/kg of live weight once a day during 15 days. It is determined that usage of “Erakond” preparation for grown cows and first-calve heifers lets us increase the immune qualities of colostrums components. It is necessary to indicate as well that biological adequacy of colostrums is definitely influenced by the way of this preparation usage (it is better to use liquid preparation “Erakond”). Immune components of colostrum influence newly born calves’ traits of unspecific immunity, it let us decrease the sickness rate at 80% and increase the live weight gains.
