Un dosage radioimmunologique a été utilisé pour mesurer les concentrations de progestérone chez les zébus “Azawak” (Bos indicus, n = 6) et taurins Gourunsi (Bos taurus, n = 5) après induction de l'œstrus. Les observations ont été menées sur 11 vaches non gestantes (groupe I composé de 3 zébus Azawak et 3 taurins Gourunsi; groupe II composé de 3 zébus Azawak et 2 taurins Gourunsi), soumises à un traitement hormonal reposant sur l’administration d’un implant de progestagène, d’une injection de prostaglandine F2alpha et, pour une partie des femelles (groupe I), d’une injection de PMSG. Les implants ont été placés sous la peau de la face externe de l’oreille et maintenus pendant une période de 10 jours. Au 8e jour du traitement, les femelles ont reçu une injection intramusculaire de prostaglandine F2 (5 mg/100 kg) et au 10e jour, au moment du retrait, une injection de PMSG (400 UI/300 kg de poids vif) a été pratiquée sur les animaux du groupe I. Chez les taurins Gourunsi et chez les zébus Azawak ayant reçu l’injection de PMSG, le traitement a été suivi d’un œstrus dans 2 cas sur 3. Chez les animaux appartenant au groupe II, l’œstrus ne fut observé chez aucun taurin et seulement chez 1 des 3 zébus. Les concentrations de progestérone mesurées au cours des phases lutéales qui ont suivi sont restées faibles chez les taurins Gourunsi. Chez les zébus Azawak, les concentrations se sont révélées plus élévées chez les femelles ayant reçu l’injection de PMSG (6,0 +/- 1,2 ng/ml) que chez celles qui n’avaient pas reçu (3,2 +/- 0,8 ng/ml).

La synchronisation des chaleurs et la fertilité en insémination artificielle des zébus ‘Azawak’ (Bos indicus, n = 66) et des taurins ‘Gourunsi’ (Bos taurus, n = 20) ont été appréciées en zone périurbaine soudano-sahélienne de Ouagadougou au Burkina Faso. La synchronisation a été effectuée avec des implants sous cutanés de progestagène placés sous la peau de l’oreille pendant 10 jours. Le traitement a été complété par l’injection de prostaglandine F2 et de PMSG, respectivement au 8ième et au 10ième jours de la pose de l’implant. Le taux d’œstrus induits observés par l’éleveur était de 94,2% dans les 48 heures qui suivaient le retrait de l'implant. Il variait significativement (P<0,05) selon les groupes zébus ‘Azawak’ et taurins ‘Gourunsi’ (100% et 75%, respectivement). Les taux de fertilité, déterminés par palpation rectale chez les zébus ‘Azawak’ et les taurins ‘Gourunsi’, ont été respectivement 24,2% et 10%. La fertilité a varié selon le moment de l’insémination: lorsque les femelles étaient inséminées 36 à 48 heures après le retrait de l’implant, les taux de fertilité ont été faibles (0 à 12,5% chez les taurins ‘Gourunsi’ et les zébus ‘Azawak’, respectivement). Par ailleurs, lorsque les inséminations étaient réalisées 24 à 36 heures après le retrait de l’implant, les taux de fertilité ont été respectivement de 50% et 42,3%. [less ▲]

This study is carried out to determine ovine pregnancy associated glycoprotein (oPAG) levels in the serum of Berrichone ewes throughout gestation and the first month post partum. The levels were determinated with heterologous RIA using bovine PAG as standard and tracer and rabbit antiserum against oPAG. The level of oPAG increased from the 4th week of pregnancy till 12-13th week and decreased slowly till 17th week, when increased rapidly and reached the highest level (around 600-700 ng/ml). In the sheep carrying twins, we observed higher levels of oPAG than in the uniparous sheep. After lambing, oPAG decreased rapidly in 4 week to basal values. The oPAG concentrations in the animals carrying twins was higher when comparised to single lamb. We concluded that the oPAG level depends on the number of lambs and term of pregnancy. The estimation of oPAG concentrations in the blood can be used as a indicator for pregnancy diagnosis. [less ▲]

Pregnancy diagnosis is a critical procedure for monitoring goat reproductive performance. In the present investigation, pregnancy-associated glycoprotein (PAG) profiles during pregnancy and first month postpartum, as well as progesterone (P4) concentrations throughout pregnancy, were determined in native goats from the north-east of Brazil. A total of 30 goats (Moxoto, n = 19 and Caninde, n = 11) were used. Peripheral blood was collected on days 0 (Day 0 = AI), 11, 16, 18, 20, 24 and 30 after AI. Samples were subsequently collected every 2 weeks until day 145, and weekly during the first month postpartum. The levels of PAG and P4 were determined by radioimmunoassay (RIA). The profiles of PAG were not different between the breeds throughout pregnancy. However, a significant effect of the week of pregnancy (p < 0.01) and the number of fetuses (p < 0.05) in PAG concentrations were found. Lower concentrations of PAG were observed during weeks 1 and 3, compared to the rest of the gestation. Thereafter, there was a significant (p < 0.05) increase in PAG concentrations from week 5 to 7 and a significant decrease (p < 0.05) in week 9. The PAG concentrations remained relatively constant until week 17, and finally decreased slowly until parturition. After parturition, PAG concentrations decreased rapidly, and continued to decrease until week 4. During pregnancy, mean P4 concentrations had weekly variations among the animals (p < 0.01) and the period of pregnancy (p < 0.01), but P4 was not affected by the breed or number of fetuses. These results indicate that PAG and P4 concentrations were similar for Caninde and Moxoto goats and that, for both the breeds, the stage of pregnancy and the number of fetuses could influence PAG production.
