摘要: La note d’embonpoint chez la vache laitiere : variabilite genetique et lien avec fertilite (synthese bibliographique). (BCS) est une mesure subjective de quantite d’energie metabolisable un animal vivant. Les changements BCS donnent des indications quant a l’importance duree balance energetique negative postpartum laitiere. Bien que perte au cours lactation presente faible heritabilite, l’heritabilite du varie en moyenne entre 0,20 0,50. De plus, le plus heritable milieu lactation, ce qui indique les differences genetiques sont davantage liees maniere dont vaches reviennent positive. mesures hautement correlees sein travers lactations. correlations rendements lait, matiere grasse proteines defavorables suggerent genetiquement hautes productrices ont tendance avoir faible, particulierement lactation. moderees favorables presentent eleve, d’une part, chances concevoir apres l’insemination d’autre nombre jours ou elles ne pas gestantes. Etant donne selection directe pour peut etre compliquee par serie facteurs, niveaux eleves BCS, apparait comme bonne option ameliorer indirectement laitieres.
