Comme le rappelle la figure annex\u00e9e, l\u2019obtention d\u2019une gestation implique une cascade optimale de variations hormonales et d\u2019\u00e9v\u00e8nements physiologiques que bon gr\u00e9 mal gr\u00e9 le protocole OvSynch capable de reproduire.\u00a0 L\u2019obtention d\u2019une concentration en progest\u00e9rone aussi faible que possible au moment de l\u2019\u0153strus est un des facteurs essentiel d\u2019une fertilit\u00e9 optimale. Or le manque de lut\u00e9olyse concernerait 12 \u00e0 21 % des vaches trait\u00e9es.<\/p>\n

Une metaanalyse r\u00e9cente relative \u00e0 11 publications concernant 9.735 vaches confirme l\u2019int\u00e9r\u00eat de l\u2019injection d\u2019une seconde dose de PGF2\u03b1 administr\u00e9e au jour 8 d\u2019un protocole Ovsynch de 7 jours.<\/p>\n

Le % de gestation s\u2019est trouv\u00e9 augment\u00e9 significativement de 5,6 % et s\u2019est traduit par une am\u00e9lioration \u00e9conomique de 8 \u00e0 28 dollars du b\u00e9n\u00e9fice par gestation ainsi obtenue malgr\u00e9 l\u2019augmentation des frais hormonaux et du travail n\u00e9cessaire. Cet effet positif a davantage \u00e9t\u00e9 observ\u00e9 chez les pluripares (+ 5,3 %) que les primipares (+4,2 %).
