Gambaran Darah Merah Domba Bunting yang Diberikan Superovulasi dan Penyuntikan Human Chorionic Gonadotropin (hCG) pada Hari ke-6 setelah Perkawinan.

Abstract

Superovulation is one of the reproduction technology used to increase the productivity of ewes. Physiological conditions of superovulated ewes are different from those of nonsuperovulated ewes. This research was conducted to observe the red blood cell (RBC) profiles of pregnant ewes superovulated and injected with hCG on the 6th day after mating. Twelf matures ewes weighing from 18-25 kg were dividied into 4 groups. The first group was not superovulated (control), the second group was superovulated before mating (SO1), the third group was injected with hCG 6 days after mating (SO2), and the fourth group was injected with PMSG and hCG before mating followed by injection of hCG 6 days post mating (S012). Estrus synchronization was done by injecting 5-15 mg of PGF2α with 11 days interval. The parameters measured were the total number of red blood cell, hematocrit value, and the hemoglobin concentration. The results obtained showed that the SO12 treatment group had higher red blood cells, hemoglobin, and hematocrit as compared to control. Based on these results it can be concluded that superovulation and added injected hCG on day-6 after mating (S012) increased red blood cell count, hemoglobin level, and hematocrit values to support maternal metabolism due to the increased fetal number and growth.
