Study of relations between nutritional value of rations and success in embryo transfer in heifers.
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.
