Ovulation and LH secretion in the goat after intravaginal progestagen sponge--PMSG treatment

Synchronization of oestrus in goats: dose effect of progestagen.

A trial was conducted to test the efficiency of different doses of intravaginal progestagen in the synchronization of different goat breeds, in the breeding season. Sixty Multiparous Boer and 60 Indigenous feral does were allocated to three treatment groups. The groups consisted of a control group (natural oestrus) (n=20/breed); 60mg MAP sponge groups inserted for 14 days plus 300IU PMSG at spo...

Ovulation and Endocrine Response after Lh-rh in Domestic Animals

cows 2 weeks after parturition and in diestrous and proestrous heifers. Serum LH concentrations increased after LH-RH treatment and the greatest response was observed in cows with ovarian follicular cysts. Serum progesterone concentrations were increased at 6 hours after LH-RH in animals which had functional luteal tissue in the ovaries but serum estradiol and estrone were unchanged. Ovarian fo...

Effects of LH-RH analogue on the ovulation rate and embryo quality in heifers superovulated with PMSG and PGF2 alpha.

Effect of Progestagen/PMSG Treatment for Oestrus Synchronization of Tuj Ewes to be Bred after the Natural Breeding Season

Ucar O. , M. Kaya, S. Yildiz , F. Onder , M. Cenesiz , M. Uzun: Effect of Progestagen/PMSG Treatment for Oestrus Synchronization of Tuj Ewes to be Bred after the Natural Breeding Season. Acta Vet. Brno 74, 2005: 385-393. The aim of this study was to investigate the effect of pregnant mare serum gonadotrophin (PMSG) and progestagen sponge on oestrus synchronization of Tuj ewes mated after breedi...

Pmsg Response in Ewes of Different Breeding Value for Reproductive Rate as an Aid to Selection

One hundred and fifty ewes with lifetime records of ovulation rate and lambing were divided into two groups on the basis of age, live weight and reproduction index (calculated from reproductive performance data). Both groups were synchronised in oestrus with progestagen sponges inserted for 14 days. At sponge removal one group received no PMSG while the other group received 400 i.u. PMSG. Eight...
