Thus, the use of sexed semen generally increases the cost of raising the heifer and a delayed entry into the lactating herd.mong the 14 herds that used â¥ 50 doses of sexed semen in heifers, conception risks were 47% Â± 3.2% (range 33 to 68%). Ten of these herds reported the use of â¥ 50 doses of conventional semen in heifers and had conception risks of 43% Â± 3.6% (range 29 to 61%).
