Production of interferon by red deer (Cervus elaphus) conceptuses and the effects of roIFN-tau on the timing of luteolysis and the success of asynchronous embryo transfer

Autor: K J, Demmers, H N, Jabbour, D W, Deakin, A P, Flint

Publikováno v: Reproduction. :387-395

The role of interferon in early pregnancy in red deer was investigated by (a) measuring production of interferon by the conceptus, (b) testing the anti-luteolytic effect of recombinant interferon-tau in non-pregnant hinds, and (c) treatment of hinds

Production of interferon by the conceptus in red deer Cervus elaphus

Autor: D. W. Deakin, H. N. Jabbour, Anthony P.F. Flint, K. J. Demmers, S. Kaluz

Publikováno v: Reproduction. 115:59-65

A type I interferon secreted by early sheep and cow conceptuses is responsible for the maternal recognition of pregnancy in these species. Interferon-tau (IFN tau) acts locally on the maternal endometrium to prevent luteolysis and prolong progesteron

Effect of age, weight, and sire on embryo and fetal survival in sheep

Autor: P R, Shorten, A R, O'Connell, K J, Demmers, S J, Edwards, N G, Cullen, J L, Juengel

Publikováno v: Journal of animal science. 91(10)

The goal was to estimate the heritabilities and genetic variances for embryo and fetal survival (ES) in sheep along with the effect of premating ewe weight, age, and bilateral or unilateral ovulation on ES. The data consisted of 11,369 records on ovu

Intravaginal progesterone devices in synchronization protocols for artificial insemination in beef heifers

Autor: M F, Martinez, G, de Nava, K J, Demmers, D, Tutt, M, Rodriguez Sabarrós, B, Smaill, M, Corti, J, Juengel

Publikováno v: Reproduction in domestic animals = Zuchthygiene. 47(2)

Two experiments were designed to investigate the administration of intravaginal progesterone in protocols for oestrus and ovulation synchronization in beef heifers. In Experiment 1, cyclic Black Angus heifers (n = 20) received an Ovsynch protocol and

Expression of the insulin-like growth factor (IGF) system in the bovine oviduct at oestrus and during early pregnancy

Autor: P G A, Pushpakumara, R S, Robinson, K J, Demmers, G E, Mann, K D, Sinclair, R, Webb, D C, Wathes

Publikováno v: Reproduction (Cambridge, England). 123(6)

Early mammalian embryo development in vitro can be enhanced by co-culture with oviductal cells and by the addition of insulin-like growth factors (IGFs). This study examined the expression patterns of the oviductal IGF system in cattle in relation to
