The present study aims at finding the use of CIDR and PGF2on the rate of pregnancy in Holstein Friesian. The study was performed on 20 Holstein Friesians. Controlled group (P0) consist of five Holstein Frisians and 15 Holstein Friesians in treatment group (P). Treatment group was further divided into three groups (P1, P2 and P3) where each group consisted of 5 Holstein Friesians. For controlled group, artificial insemination was done at 72 hour after second prostaglandin injected. Holstein Friesians in P1 group was artificial inseminated two days after CIDR removal at 9 hour. Holstein Friesians from P2 group was artificial inseminated two days after CIDR removal at 15 hour while Holstein Friesians in P3 group was artificial inseminated two days after CIDR removal at 24 hour. At Day 30 after artificial insemination, pregnancy was diagnosed using ultrasonography. The percentage of pregnancy of the cows in all the groups was then recorded to compare the effect of the treatments. The result showed that Holstein Friesian in controlled group (P0) yield a pregnancy rate of 80 %, while all Holstein Friesian from P1, P2 and P3 yield a percentage of 100 %. Therefore, this research showed a positive feedback, consistent with the objective.
