Short-term goal Of this research was to find a method of determining the design model of plastic progesterone implants, while the long-term goal was to support programs for improving the genetic quality of sheep and increase productivity through estrus induction technology and treatment of infertility without waiting for the occurrence of natural estrus. Methods of investigation were carried out on experimental animals as many as 20 healthy, non pregnant, adult female of sheep in a state of lust. Experimental design used was completely randomized design which is divided into four treatment groups. Each group consisted of 5 sheep. Data were analyzed by Analysis of Variance and followed with the least significant difference test. The groups consisted of P0 as a control group receiving injections of 7 mg PGf2a, PI group received 50 mg progesterone, P2 60 mg, and P3 70 mg. Subsequent diagnosis of estrus was performed start from day 11. The results showed that the administration of PGf2a and plastic implant had effect on time of estrus onset. The use PGf2a results in slower estrus onset (p<0.05) compared to the use of plastic progesterone implants. Estrus induction and synchronization with a dose of 50 mg MPA in the form of plastic progesterone implants has no significant difference with 60 mg or 70 mg and still effective to induce sstrus. This dose, therefore, can be regarded as the most efficient one compared to treatment with other doses
