RESPONS ESTRUS SAPI RESIPIEN FH YANG DISINKRONISASI DENGAN HORMONE GnRH, ESROGEN, PROGESTERON DAN PROSTAGLANDIN
ABSTRACT: This study was aimed
to test the effectiveness injection of several combination hormone of GnRh, estrogen,
progesterone and prostaglandin e to the response of estrus, onset estrus and
duration of estrus Friesian Holstein dairy cows recipient. This study was used
fifteen dairy cows recipient not pregnant, which were divided into three
treatment method of synchronization of estrus. The three tatments were P1:
injection 137,5/5 ml prostaglandin hormone (Capriglandin) on day- 0 and repeat
on day-11, P2: injection GnRh (Fertagyl) 100 µg/ 2 ml on day-4 and injection prostaglandin
hormone (Prostavet) 2 ml on day-11, and P3: injection progestere hormone (Potahormon)
250 g/ 40 ml and estrogen hormone (Ovalumon) 40,000 IU/ 2 ml on day-5 an
injection prostaglandin hormone (Capriglandin) 137,5 mg/ 5 ml on day-11. Data
was analyzed by Chi-Square Analysis for all of the parameters, IE: estrus
response, onset estrus and duration of estrus, The results showed that
presentage of response estrus FH cow recipient after injection of a hormone estrus combination
overall reaches 100%, onset estrus 72 hours (60%) and duration of estrus 72
hours. The treatments were effective way for synchronization of estrus FH cows
recipient. It was concluded that synchronization of estrus FH cows recipient using
GnRH hormone, estrogen, progesterone and prostaglandin as good in all of the
parameters. Recommendation for synchronization of estrus using injection
progesterone hormone (Potahormon) 250 g/ 40 ml and estrogen hormone (Ovalumon)
40,000 IU/ 2 ml on day-5 and injection prostaglandin hormone (Capriglandin)
137,5 mg/ 5 ml on day-11.
