L'outil le plus important pour \u00e9valuer le d\u00e9veloppement d'une race est constitu\u00e9 par les tendances g\u00e9n\u00e9tiques. Cela signifie que divers facteurs environnementaux susceptibles d'influencer les valeurs ph\u00e9notypiques ont \u00e9t\u00e9 corrig\u00e9s. L'analyse est men\u00e9e sur plusieurs ann\u00e9es. Les tendances g\u00e9n\u00e9tiques sont \u00e9valu\u00e9es chaque ann\u00e9e en avril, en liaison avec l'ajustement de la base lors de l'estimation de la valeur d'\u00e9levage.<\/p>\n\n\n

Tendances de l'objectif de s\u00e9lection 2026<\/h2>\n\n\n

Pour les caract\u00e8res \u00e0 faible h\u00e9ritabilit\u00e9, il faut plus de temps pour que les ajustements des objectifs de s\u00e9lection se refl\u00e8tent dans les tendances g\u00e9n\u00e9tiques. La fertilit\u00e9 des femelles a re\u00e7u un poids beaucoup plus important lors de la formulation de l'objectif de s\u00e9lection il y a cinq ans. Cependant, un effet fort sur les tendances g\u00e9n\u00e9tiques n'est pas encore \u00e9vident. D'autre part, la tendance est fortement positive pour la sant\u00e9 de la mamelle ainsi que pour les caract\u00e8res morphologiques, en particulier la mamelle. L'\u00e9volution de la disposition des trayons \u00e0 l'arri\u00e8re et de la position des trayons fait l'objet d'un suivi constant. La fonctionnalit\u00e9 des trayons pour la traite doit \u00e9galement \u00eatre garantie \u00e0 l'avenir, pas seulement dans les exploitations dot\u00e9es d'un syst\u00e8me de traite automatique.<\/p>\n\n\n\n
