title: Study of relations between nutritional value of rations and success in embryo transfer in heifers.
abstract: Experimental observations on the influence of composition and nutritional value of rations upon the success of transfer of early embryos were realized in 134 recipients-heifers. Greater success of embryo transfers (66.0%) was observed in recipients at the age 18-22 months, live weight 330-380 kg at rations with 85-95% share of high quality roughage with moderately increased content and concentration of energy, good state of health and condition.
