En élevage ovin-lait, la réussite à l’insémination artificielle (IA) est un facteur clé pour la maîtrise de la reproduction et la mise en œuvre des schémas de sélection. Elle a été évaluée : 1) par dosage de la PAG plasmatique vingt huit jours après l’insémination ; 2) par l’analyse des résultats de mise bas (MB). La différence entre ces deux valeurs permet d’estimer le niveau de pertes embryonnaires et avortements. L’étude porte sur quatre-vingt cinq lots d’insémination (8841 brebis de races Manech / Latxa tête rousse et tête noire principalement) réalisés de mai à août 2007, dans trois centres d’insémination (CIA) transfrontaliers : Navarre, communauté autonome d’Euskadi et Pyrénées Atlantiques. Les données de contrôle laitier et des CIA ont été mobilisées pour étudier les facteurs de variation de la fertilité individuelle. Un deuxième volet de l’étude, à l’échelle des lots, traite des conduites d’élevage pendant la période de lutte. Il s’appuie sur des enquêtes (alimentation, chantiers d’IA, sanitaire). La fertilité à vingt huit jours s’élève à 61,3 % et celle à la MB à 55,2 %. Les pertes sont en moyenne de 6,2 %. Pour 2/3 des lots elles sont inférieures à 7 %. L’analyse des facteurs individuels, tant pour la fertilité à vingt huit jours qu’à la MB, confirme les effets classiques des facteurs de variation de la fertilité à l’IA : intervalle IA-MB précédente, âge des femelles, mode de reproduction de la campagne précédente, production laitière au moment de l’IA, qualité de la semence. Les niveaux de pertes sont plus élevés pour les jeunes ou lorsque l’intervalle est court. Au niveau des conduites d’élevage, on observe une interaction forte race*région associée à des périodes d’IA et des conduites alimentaires différentes, mais avec des effets peu ou pas significatifs de ces conduites. Les enquêtes sanitaires font apparaître des niveaux de risques et des pathologies comparables d’une région à l’autre et élevés. Pour les lots à pertes élevées, celles-ci ont pu être reliées à des problèmes pathologiques particuliers, mais non prévisibles. Une telle approche, assez complète et globale des conduites, aura permis de renouveler le conseil en élevage et d’élargir les capacités d’intervention des techniciens. [less ▲]

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 days associated with estradiol valerate, prostaglandin F2alpha (PGF2alpha) and pregnant mare serum gonadotropin (PMSG) injections. Treatment 2 (T2, n = 6) consisted in two PGF2alpha injections 11 days apart, followed by the administration of PMSG two days after the second prostaglandin injection. Blood samples were collected every three hours during five days after implant removal (T1) or PMSG injection (T2) for LH measurements. The proportion of induced estrus was higher in T2, but the difference was not significant. In general, the elapsed time until the estrus onset tended to be shorter in norgestomet-treated animals (35.9 ± 3.9 h) than in prostaglandin-treated ones (49.5 ± 5.8 h). Seven out of nine norgestomet-treated cows, and only two out of the six treated with PGF2alpha, presented a peak of LH. The mean interval from the end of treatments to LH peak tended to be longer in PGF2-treated females than in norgestomet-treated ones. One female presenting abnormally high LH concentrations after implant removal did not show a peak of LH during the observation period. [less ▲]
