Abstract

A study was carried out to determine the effect of Pregnant Mares Serum Gonadotrophin (PMSG) on the weigth of ovary, the number of developing follicles and the onset egg production in ducks with delayed egg production. In this study, as many as 40 Bali ducks were used and they were divided into 4 groups in a completelty randomized design i.e. control group (TO) treated with NaCl 0,9%, group T1 treated with PMSG dose 5 IU per duck, group T2 treated with PMSG dose 10 IU per ducks and group T3 treated with PMSG dose 20 IU per duck intramuscularly. The weight of ovary increased significantly with the increasing dose of PMSG, i.e dose 0 IU (21,04 + 3,90 gram), dose 5 IU (25,40 + 5,31 gram), dose 10 IU (49,52 + 5,05 gram) and dose 20 IU (59,30 + 4,66 gram). The number of developing folilicles also increased significantly with the increasing dose of PMSG, i.e dose 0 IU (1,4 + 0,5 follicles), dose 5 IU (2,4 + 1,34 follicles), dose 10 IU (5,8+2,07 follicles) and dose 20 IU (8,6+1,67 follicles). In addition, the onset of egg production was shortened significantly with the increasing dose of PMSG, i.e. dose 0 IU (19,0+1,58 days), dose 5 IU (16,8+1,3 days), dose 10 IU (14,2+1,92 days) and dose 20 IU (9,6+14 days). PMSG treatment was proven to increase the egg production capability of ducks with delayed egg production.

Abstract

This study aims were to determine the proper time for insemination and the progesterone level ofpregnant Bali cattle. Complete randomized design method was used in this study. The study consisted ofthree treatment groups i.e. Group I, animals were inseminated at 0 hour (on estrus), group II, inseminatedat 12 h post-estrus and group III inseminated at 24 h post-estrus. Estrus was observed two times a day ie.in the morning (6:00 to 8:00 am) and afternoon (16:00 to 18:00 pm) which was characterized by transparentvaginal discharge. The results showed that the highest percentage of pregnancy occurred when the cattlewere inseminated at 24 h post-estrus (100%), however, statistically this was not significant different (P>0.05) to animals that were inseminated at 12 h post-estrus (75%). Moreover, no pregnancy (0%) wasobserved in cattle that were inseminated at estrus. The progesterone level of pregnant bali cattle increasedas the period of gestation increased, being 15.43 ± 0.50 ng/mL at 30 days of gestation, 17.16 ± 0.34 ng/mLat 60 days of gestation and 20.78 ± 0.59 ng/mL at 90 days of gestation. In conclusion, the best time forinsemination in Bali cattle is at 24 h post-estrus and progesterone level seems to increase as the older thegestation period.
