Effective species conservation efforts require insight into whether a species’ extent of occurrence may shift due to changing climate, habitat loss, or both. The extent of occurrence of the threatened boreal population of woodland caribou (Rangifer

The percentage of estrus induction and plasma LH concentrations were examined in 15 Azawak zebu cows submitted to two different estrus synchronization protocols. In the first treatment (T1, n = 9), the cows received a norgestomet ear-implant for 10 d

The aim of this experiment was to study the kinetics of anti-eCG (equine chorionic gonadotrophin) antibodies in relation to eCG dose (8 or 25 IU) and number of injections (n = 11) in comparison with a control group (no injection), and to relate antib

The aim of the present study was to characterize the plasmatic profiles of pregnancy-associated glycoproteins (PAG) and progesterone during gestation and two weeks postpartum in Ouled Djellal ewes. Twenty-five ewes were sampled weekly after estrus sy

Previous studies carried out in sheep (Chupin et al., 1985) and in goats (Nowshari et al., 1995; Martemucci et al., 1996) have underlined the importance of both FSH and LH to induce a good superovulatory response, but the results on the LH amount nec

This study was designed to establish the factors, if any, which could affect plasma pregnancy-associated glycoprotein-1 (PAG-1) expression in a study population of 87 pregnant, high-producing dairy cows. The factors examined were: semen providing bre

This paper describes the first identified chorionic PAGs in the European bison (Eb), named EbPAGs, predominantly expressed during early and mid-pregnancy (45–120 day post-coitum ; dpc). Many EbPAGs were extracted from various cotyledonary tissues,
