Influence of Biologically Active Supplement “Gumelan-1” at Reproductive Traits of Cows
Abstract
A recipe of biologically active supplement “Gumelan-1” is developed and samples are prepared. It’s chemical composition is studied. Estimation of its influence in different dozes at growth and calves’ health under 3 months of age as well as at indexes reflecting reproductive system traits was carried out. More effective doze of “Gumelan-1” of 0,2 ml/kg per 1 kg of live weight was determined. The supplement promoted decrease of service-period of experimental cows at 13 days on average, decrease of insemination index at 0,7, birth of live young cattle with higher growth energy.
