Accumulation of Sex Steroids in Preimplantation Pig Blastocysts and Their Importance for an UndisturH-progesterone was 132 . 18 cpm (x . SEM) and apparently was nonspecific since no significant inhibition could be determined in the presence of a 100-fold excess of unlabelled progesterone or estradiol-17ß. After 6 hrs. of incubation, the uptake of H-estradiol-17ß was 134 . 25 cpm, but apparently wa

Periovulatory Hormone Profiles in Relation to Embryonic Development and Mortality in Pigsobserved approximately 1Oh after the onset of oestrus, although large variations from 20h before to more than 24h after the onset of oestrus were noticed. The time interval between the LH peak and ovulation, however, was rather constant and so a large variation with regard to the time interval betwe

The Influence of Progesterone Profile on Embryo Survival in Eweshat low pre-luteal levels are required from immediately after oestrus until the level increases to luteal phase levels on Day 4 or 5. In intact, mated ewes, differences in embryo survival were associated with variation in the progesterone profile. Embryo survival was lower in ewes with lower levels

Embryo Loss Following Embryo Transfer in Cattle and Swines are transferred non-surgically giving rise to an average pregnancy rate of 58.8% (4638/7882) on day 60–90 following ipsilateral transfer of a single embryo to synchronized recipients. It is believed that interfarm variation and recipient quality contribute to the variation. The percentage of recip

Genetic Constitution of Early Stage Pig Embryos and Embryo Mortalitys such as mouse, Chinese hamster and rabbit, and with man. It can be concluded that of the categories of chromosome mutants that are mostly of concern for embryonic death, aneuploidy and polyploidy, man has the highest incidence of both. For the other species, levels of both types of abnormalities g
