Croissance soutenue<\/strong><\/h1>\n

Foins fin mai, regains d\u00e9but juillet !<\/strong><\/span><\/h2>\n
Avec des temp\u00e9ratures plus \u00e9lev\u00e9es sur des sols encore humides et quelques \u00e9pisodes orageux, les croissances d\u2019herbe au p\u00e2turage restent soutenues et favorables \u00e0 la production laiti\u00e8re. Le calcul des jours d\u2019avance au p\u00e2turage permis par l\u2019application \u00ab HappyGRASS \u00bb avec des mesures d\u2019herbe herbom\u00e8tre apporte une aide \u00e0 la gestion des surfaces pour d\u00e9brayer des parcelles.\u00a0 La fenaison a d\u00e9marr\u00e9 et devrait se poursuivre si les conditions m\u00e9t\u00e9o sont propices.<\/p>\n

Rep\u00e8res conduite du troupeau : du 15 au 22 mai 2023<\/strong><\/p>\n\"\"\n

Point de vue des \u00e9leveurs SCEA des Coteaux \u00e0 Lavigny (290 m\u00e8tres d\u2019altitude)<\/strong><\/span><\/p>\n
“Il faut bien l\u2019admettre, on s\u2019est fait d\u00e9passer par l\u2019herbe. La pousse a \u00e9t\u00e9 extr\u00eamement rapide cette ann\u00e9e, en l\u2019espace de 4 jours tout est monter \u00e0 \u00e9pi. Le p\u00e2turage de ces derniers jours a \u00e9t\u00e9 un peu compliqu\u00e9 et les refus importants. Le lait au tank a baiss\u00e9 ; en revanche le TB \u00e0 41,4 et le TP \u00e0 35 restent bon. Les vaches sont compl\u00e9ment\u00e9es avec 3 kg de foin.<\/p>\n
Heureusement, la m\u00e9t\u00e9o nous a permis de r\u00e9aliser des fauches pr\u00e9coces afin de remettre rapidement des parcelles dans le circuit de p\u00e2turage. La croissance est bonne et nous permet aujourd\u2019hui de repartir sur de bonnes repousses.”<\/p>\n
Propos recueillis par Julie Petiteau, conseill\u00e8re \u00e0 la Chambre d\u2019Agriculture du Jura.<\/em><\/p>\n

T\u00e9moignage des \u00e9leveurs du GAEC Beguiot \u00e0 Cosges<\/span><\/strong><\/span><\/p>\n
“Aujourd’hui, le GAEC Beguiot, situ\u00e9 en plaine jurassienne, produit 26 Kg de lait par vache par jour \u00e0 8100 kg de potentiel.<\/p>\n
<\/div>\n
\n
On d\u00e9nombre un chargement instantan\u00e9 tr\u00e8s fort depuis le d\u00e9but de saison avec les croissances folles de ce printemps ! L’exploitation se situe aujourd’hui sur un chargement de 21 ares\/VL avec un temps de retour tr\u00e8s faible de 14 jours de moyenne. N\u00e9anmoins, avec la bise de la semaine derni\u00e8re, on observe un net recul de la croissance avec un sol tr\u00e8s sec qui nous apporte une faible croissance de 35 kg MS\/ha\/Jr.<\/p>\n
Malgr\u00e9 \u00e7a, l’\u00e9levage travaille avec un m\u00e9lange fermier \u00e0 14.5 % de MAT avec une valorisation des fourrages \u00e0 17.6 kg de lait\/VL\/jr et 148 g de concentr\u00e9 par kg de lait. Le stade avanc\u00e9 des plantes et les forts stades de lactation \u00e9galement ne permettent pas d’optimiser plus ces performances technico-\u00e9conomiques, mais qui sont plut\u00f4t bonnes dans ces conditions. Une des cl\u00e9s est probablement d’avoir sorti les animaux tr\u00e8s t\u00f4t dans la saison (mi-f\u00e9vrier).<\/p>\n
De plus, la souplesse va nous venir de la fauche en foin des pr\u00e9s destin\u00e9s au p\u00e2turage r\u00e9alis\u00e9e la semaine derni\u00e8re, ce qui va permettre \u00e0 l’\u00e9leveur d’assurer pleinement le p\u00e2turage des vaches pour les prochaines semaines !”<\/p>\n
