PENGARUH DOSIS GnRH (Gonadotropin Releasing Hormone) TERHADAP LAMA ESTRUS DAN KUANTITAS KORPUS LUTEUM SAPI PESISIR
Abstract: This study aims to
determine the effect of giving prostaglandin F2α (PGF2α) combined hormone GnRH
with different doses of the length of estrous and quantity of the corpus
luteum. The material in this study using 12 head Pesisir Cattle age of 3-4
years with a body weight 140,6,87±5.51 kg. The treatment in this study
consisted of 3 treatment. A treatment that injection of the hormone GnRH dose
of 50 μg PGF2α 48 hours after injection of 5 ml, treatment B injection of the
hormone GnRH dose of 100 μg 48 hours after PGF2α injection of 5 ml, treatment C
injection of the hormone GnRH dose of 200 μg 48 hours after injection of PGF2α
5 ml. The resulting data were analyzed using Completely Randomized Design with
4 replications. The results showed that the average length of estrous treatment
A (18.31±1.22 hours), B (18.50±0.34 hours) and C (17.81±1.28 hours) showed
nodiffer significantly (P>0,05) between treatments. The average quantity of
the corpus luteum treatment A is with 3.75±1.50; B 5.00±1.55 and C 4.50±0.58
fewer fruits not significantly different (P>0.05) by treatment. From the
study it can be concluded that the hormone GnRH 50 μg - 200 μg after injection
of PGF2α positive influence on the length of estrous, and the number of corpus
luteum.
