Les \u00e9valuations g\u00e9n\u00e9tiques permettent d\u2019estimer la valeur g\u00e9n\u00e9tique des animaux en prenant en compte toutes les informations collect\u00e9es \u00e0 leur sujet. Ce sont \u00e0 la fois les performances r\u00e9alis\u00e9es par l\u2019animal, ses liens de parent\u00e9s et son ADN qui sont pris en compte pour calculer sa valeur g\u00e9n\u00e9tique.<\/p>

ISET<\/summary>

L\u2019index de s\u00e9lection totale (ISET) repr\u00e9sente l\u2019objectif principal de s\u00e9lection de la race Holstein en Suisse. Depuis 2015, l\u2019index est commun aux deux organisations d\u2019\u00e9levage avec des animaux Holstein. L\u2019ISET est r\u00e9guli\u00e8rement adapt\u00e9 aux changements sur le march\u00e9 afin de permettre la s\u00e9lection de vache r\u00e9pondant aux conditions actuelles de production.<\/p>

L\u2019ISET est form\u00e9 de trois composants principaux qui ont \u00e9galement leurs index propres\u00a0:<\/p>

  • La production \u2013 IPL<\/li>
  • La conformation \u2013 ITP\u00a0<\/li>
  • Les crit\u00e8res fonctionnels \u2013 IFF<\/li><\/ul>

    La pond\u00e9ration des crit\u00e8res sp\u00e9cifique dans l\u2019ISET tient compte de la corr\u00e9lation entre eux. Le but est d\u2019am\u00e9liorer directement ou indirectement les qualit\u00e9s demand\u00e9es de la race Holstein (production, conformation, sant\u00e9) sans porter pr\u00e9judice \u00e0 d\u2019autres crit\u00e8res importants (d\u00e9roulement du v\u00ealage, persistance, etc.)<\/p>

    Les pond\u00e9rations actuelles sont pr\u00e9sent\u00e9es ci-dessous ainsi que l\u2019effet attendue sur l\u2019\u00e9volution g\u00e9n\u00e9tique de la race Holstein.<\/p>

    \"\"<\/figure>

    L\u2019ISET est publi\u00e9 sous la forme d\u2019un index avec une moyenne de 1000 et un \u00e9cart-type de 100. Cela signifie que les animaux \u00e0 1200 ISET et plus repr\u00e9sentent approximativement le top 2% de la race.<\/p>

    Les composants de l\u2019ISET (IPL, ITP, IFF) sont publi\u00e9 avec une moyenne de 100 et un \u00e9cart-type de 10.<\/p><\/details>

    IPL<\/summary>

    L\u2019IPL regroupe les VE de production laiti\u00e8re. Il tient compte des quantit\u00e9 de mati\u00e8re grasse et de prot\u00e9ine produite. Le but de l\u2019IPL est de continuer \u00e0 augmenter la teneur en prot\u00e9ine, stabiliser la teneur en mati\u00e8re grasse tout en augmentant la production.<\/p><\/details>

    ITP<\/summary>

    L\u2019ITP est un index morphologique qui pr\u00e9dit la note de classification en 1re<\/sup> lactation. Il tient compte de tous les \u00e9l\u00e9ments de la description lin\u00e9aire. Dans le calcul de l\u2019ISET, seuls les valeurs pour les membres et pour le syst\u00e8me mammaire sont prise en compte.<\/p><\/details>

    IFF<\/summary>

    L\u2019index pour les crit\u00e8res fonctionnels (IFF) contient les valeurs d\u2019\u00e9levage pour la sant\u00e9 (cellules), la long\u00e9vit\u00e9, la fertilit\u00e9, la stabilit\u00e9 m\u00e9tabolique (BCS) et la stature.<\/p><\/details>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
