난포자극호르몬(Follicle Stimulating Hormone) 투여 농도가 칡소 수정란의 생산과 이식에 미치는 영향 Effect of Follicle Stimulating Hormone Dosage on the Production and Pregnancy of Embryos Derived from Korean Brindle Cows원문보기
한우는 털색에 따라 황소, 칡소 또는 흑소로 분류되고, 칡소는 1,700여두만 전국에 사육되고 있어 보존과 증식이 절실히 요구되고 있으나, 연구는 아주 부족하다. 본 연구에서는 칡소의 보존과 대량증식을 위하여 follicle stimulating hormone(FSH) 용량이 수정란 생산 및 이식에 미치는 효과를 조사하였다. FSH 240 mg과 280 mg을 각각 처리하여 회수수정란, 이식가능한 수정란은 차이가 없었으나, 임신율이 280 mg이 46%로 유의하게 높았다(p<0.05). 칡소 송아지의 생시체중이 인공수정 방법은 평균 25.6 kg, 수정란이식 방법은 평균 24.8 kg으로 비슷하였다.

Korean native cattles (Han woo) are divided yellow, tiger(blinder), and black by coat color. Chikso has tiger coat color, which cultured about 1,700 heads within Korea. However there were a few researches reported about preservation and production. This study was conducted to investigated that the effect of follicle stimulating hormone (FSH) dosage(240 mg and 280 mg) on the embryo production, pregnancy and calf birth weights. There were no difference total embryo and transferable embryo between FSH 240 mg or 280 mg treatment, but pregnancy rate was increased 46% in embryos derived from 280 mg group than 240 mg group's 29.6%. The birth weight of Chikso calves was similar between artificial insemination(25.6 kg) and embryo transfer(24.8 kg) groups.
