Abstract

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 Il then observed in the onset of symptoms estrus and thus to artificial insemination performed. Pregnancy examinations performed 30 days after artificial insemination by ultrasound and blood serum progesterone levels. The results snowed that the administration of PGf2a and plastic implant had effect on time of estrus onset. On examination progesterone eels after 30 days after artificial insemination, progesterone levels are highest in the P2 treatment (60 mg), but not significantly different from the P3 treatment (70 mg dose). While P3 treatment was not significantly different with PI treatment (dose of 50 m). Low progesterone levels occur in treatment PO is significantly different from other treatments. For pregnancy test results indicate that all Fat Tailed Sheep experienced pregnancy, either by ultrasound or blood serum progesterone levels
