Anti-PMSG antibody levels in sheep subjected annually to oestrus synchronisation

Anti-PMSG antibody levels in sheep subjected annually to oestrus synchronisation.

Estimation of the long-term consequences on reproduction performance of the oestrus synchronisation treatments that are annually applied to ewes was carried out on nine officially controlled dairy flocks in the Roquefort region of France. A hormonal treatment combining the insertion of a vaginal fluoro-gestone acetate (FGA) sponge for 14 days and the injection of about 500 IU of pregnant mare s...

Haemoglobin genotype, reproductive performance and response to PMSG in sheep.

ewes to superovulatory doses of PMSG. A subsequent report of a similar study of Welsh mountain ewes found no association between Hb type and response to PMSG (Trounson, Willadsen, Moor & Tucker, 1976). Egg-transfer experiments with Finnish Landrace (Finn) and Galway donors provided an op¬ portunity to extend the findings of Pant & Pandey (1975) and Trounson et al (1976). In addition to typing a...

Synchronisation of Ewes at the Second Oestrus after Progestagen Treatment

To determine the change in distribution of ewes exhibiting oestrus at the first and second oestrous cycles after progestagen treatment, data were examined from six experiments in which 430 ewes received progestagens but experienced no fertile mating at the first post-treatment oestrus. Three progestagens, three breeds and two seasons were involved. In all experiments there were more silent heat...

Anti-cholesterol antibody levels in hereditary angioedema

Hereditary angioedema (HAE) is a rare disorder caused by the deficiency of the C1-inhibitor gene (C1INH) and characterized by recurrent bouts of angioedema. Autoimmune disorders frequently occur in HAE. Previously we found, that danazol has an adverse effect on serum lipid profile: reduced high-density lipoprotein (HDL) and elevated low-density lipoprotein (LDL) cholesterol levels are associate...
