En secteur plaine o\u00f9 la croissance d\u00e9marre, il conviendra d\u2019avoir des conditions m\u00e9t\u00e9o favorables avec une portance des sols suffisante pour assurer de bonnes conditions de mise \u00e0 l\u2019herbe.\u00a0 Au 14 mars, le rep\u00e8re des 300 degr\u00e9s cumul\u00e9s au 1er<\/sup> f\u00e9vrier pour la mise \u00e0 l\u2019herbe \u00e9tait presque atteint avec 298 \u00b0C \u00e0 Besan\u00e7on, mais seulement 265 \u00b0C \u00e0 Rioz.

Point de vue des \u00e9leveurs\u00a0: GAEC QUIROT \u00e0 Chassey (Lait Standard), zone de plaine (39)<\/strong><\/span><\/h3>\n

Le Gaec Quirot est en syst\u00e8me lait standard avec des Montb\u00e9liardes \u00e0 plus de 8\u00a0000kg de potentiel ainsi qu\u2019une ration ensilage de ma\u00efs et enrubann\u00e9. En ce d\u00e9but de saison, les vaches sont sorties (uniquement la journ\u00e9e) du 22 f\u00e9vrier au 10 mars. La quantit\u00e9 d\u2019herbe disponible \u00e9tait encore assez faible (4.7 cm en moyenne sur les parcelles le 02\/03). Seule la quantit\u00e9 d\u2019enrubann\u00e9 a \u00e9t\u00e9 diminu\u00e9e lors de la sortie (4 kg bruts au lieu de 7.5 kg). \u00c0 la suite des pr\u00e9cipitations et en raison de la non-portance des sols, les vaches sont de nouveau \u00e0 l\u2019int\u00e9rieur depuis une semaine. Elles disposent en moyenne de 23kg de ma\u00efs ensilage, d\u2019enrubann\u00e9, de foin et d\u2019environ 8 kg de concentr\u00e9s.<\/p>\n

\u00ab\u00a0Le syst\u00e8me de p\u00e2turage tournant a \u00e9t\u00e9 mis en place au printemps dernier (mars 2020), \u00e0 la suite d\u2019un AGRILEAN (diagnostic technico-\u00e9conomique r\u00e9alis\u00e9 par le CER, la chambre d\u2019agriculture et EVAJURA). Celui-ci \u00e9tait un moyen de diminuer les co\u00fbts alimentaires mais aussi la part de ma\u00efs ensilage dans la ration en p\u00e9riode estivale. Cela nous a \u00e9galement permis de remettre l\u2019alimentation au centre du syst\u00e8me d\u2019\u00e9levage\u00a0\u00bb.<\/p>\n

\u00ab\u00a0Les objectifs pour cette ann\u00e9e seront d\u2019am\u00e9liorer notre gestion du p\u00e2turage gr\u00e2ce aux mesures d\u2019herbe et \u00e0 l\u2019accompagnement du technicien. Cela nous permettra d\u2019acqu\u00e9rir plus de connaissances dans cette pratique qui reste nouvelle pour nous, en sachant que nous nous faisons rapidement d\u00e9border par l\u2019herbe au printemps et que la s\u00e9cheresse est vite arriv\u00e9e. Sur le long terme, le but est de diminuer la part de ma\u00efs distribu\u00e9 pour mieux valoriser l\u2019herbe sur une p\u00e9riode plus importante.\u00a0\u00bb<\/p>\n
