Abstract

Efficacy of oestrous synchronization and post-treatment fertility was studied in a herd of 149 dairy goats (Swiss breed no.=104, indigenous Greek breed no.=45) kept under an extensive farming system. All does were synchronized during the transitional period (during July prior to the breeding...

Abstract

The objective of the study was to evaluate the use multiple ovulation and embryo transfer (MOET) techniques in an indigenous Greek dairy breed of sheep. We stimulated selected donor ewes of the Karagouniko breed to produce large numbers of embryos after the induction of multiple ovulations by...

Abstract

A total of 2567 indigenous Greek ewes (Chios, Vlachiki and Vlachiki × Chios breeds) were used to determine the optimum time for insemination, following synchronization of oestrus with MAP (Veramix)-impregnated intravaginal sponges and PMSG (Intergonan) during non-breeding season. Within each breed...

Abstract

The objective of this field trial was to compare the odds of pregnancy at 25 days (P25) and at 60 days (P60), of embryonic death (ED) between 25 and 60 days, and of non-pregnant cows returning to heat 20-25 days after artificial insemination (AI). Three fixed-time insemination protocols involving...

Abstract

4109 goats were synchronized in oestrus with intravaginal medroxyprogesterone acetate and PMSG, and inseminated. Insemination was done once (50-55 h after sponge withdrawal) or twice (36 and 60 h after sponge withdrawal) with fresh semen collected during the non-breeding season (June-August) and...

Abstract

The reproductive performance of 1250 Mytilini [Mytilene] ewes after oestrus synchronization and AI was studied in the Evros region of Greece. All ewes were treated with progestogen-impregnated sponges which were removed after 14 days; ewes were then injected with PMSG. 48 and 60 h after sponge...

Abstract

The effect of oestrus synchronization was studied in 75 flocks of 6689 adult goats of an unspecified Greek breed, under extensive range conditions, and in 50 flocks of 2057 adult Saanen goats, housed in the Evros area of Greece. All animals were synchronized for oestrus during the summer with...

Abstract

The effect of fertilization by 2 methods after oestrus synchronization was studied in 90 housed flocks of 3180 adult Saanen goats, in the Evros region of Greece. All goats were treated during the summer with progestogen-impregnated sponges which were removed after 17 days; goats were then injected...

Abstract

Plasminogen-activator activity (PAA), plasminogen-activator inhibitor (PAI) and plasmin inhibitor (PI) were studied in the cervical mucus of Friesland, Chios, Serrai and Karagouniko ewes during natural oestrus, synchronized oestrus and the 1st oestrus after synchronized oestrus. PAA increased by...

Abstract

The concentrations of oestradiol-17β and progesterone in the blood were studied during natural oestrus, synchronized oestrus and the 1st oestrus after synchronized oestrus in Friesland, Chios, Serrai and Karagouniko sheep. During natural oestrus, significant variations in oestradiol-17β...
