Abstract
This study was conducted to investigate the effects of disregarding of heat detection on embryo production in superovulation of Hanwoo cows. Donors which showed 1 or 2 times of normal heat and had no abnormality of reproductive tract were selected The superovulation was performed injection of 2.5 mL FSH (Antorin R-10, Japan) 2 times on 5 days before next heat and continuously with the reduction of dose to 0.5 mL of first injection 2 times in a day for next 3 days. Otherwise, the donors of CIDR group were inserted CIDR plus (with the capsule of estradiol benzoate 10 mg) on Day 10 from standing heat for 9 days. On 6 days from insertion of CIDR, FSH was injected above same manners. The response according to the natural heat and CIDR were $82.2\%,\;89.7\%$, respectively. There were no difference between both treatments. The recovery rates of embryos were 7.7, 10.5, respectively and transferable embryos were 3.4, 3.8. There showed significant difference between both treatments (p<0.05). These results suggested that disregarding of heat detection in superovulation could be produced transferable embryos for embryo transfer and preserve the donors from the excess hormonal administration and maintain the economical lift span of genetically available Hanwoo donors.
