다양한 발정유기 방법의 반복처리에 따른 분만율은 평균 로 나타났고 생시체중에 있어서 자연 발정구와 발정 유기구에서 차이를 거의 보이지 않았으며 송아지 육성율은 농가의 사육경험이 많을수록 우수한 경향이었고 발정 동기화의 반복처리가 차기번식에 미치는 영향은 확인할 수 없었다. 1. 발정 유기구와 자연 발정구에서 출생한 송아지의 생시체중은 암송아지에서 각각 23.9kg, 24.0kg이었고, 수송아지에서 26.2kg, 24.9kg로써 처리간 차이가 없었다. 2
This study was conducted to investigate the effects of repetition usage of various estrus synchronization and seasonal breeding in Hanwoo. Body weight(kg) at birth and weaning in calves produced by seasonal breeding are 24.0kg, 75.6kg in female, 24.9kg, 78.3kg in male, respectively.

Delivering rates by induced estrus methods in , PRID, CIDR and were , , and , respectively. Conception days of post-partum following to induced estrus methods in Control, PRID, CIDR and were 137.1, 147.6, 141.3, 116.6 and 118.0 days, respectively.
