Des conditions plus favorables attendues <\/strong><\/h1>\n
<\/pre>\n
La fraicheur a ralenti la pousse sur les plateaux et plus en altitude, tandis qu’en plaine, les croissances sont actives avec des valeurs sup\u00e9rieures aux moyennes de saison. En sols non portants, les conditions pluvieuses ont compliqu\u00e9\/retard\u00e9 le tour de p\u00e2turage. Parcelles non portantes = p\u00e2turage de 3 heures par jour et abandon si dactyle\/f\u00e9tuque \u00e0 plus de 10 cm.<\/strong><\/span><\/h2>\n
D\u2019importantes pr\u00e9cipitations accompagn\u00e9es de fraicheur ont perturb\u00e9 ou retard\u00e9 les mises \u00e0 l\u2019herbe. Des conditions plus favorables \u00e0 la croissance et \u00e0 la valorisation de l\u2019herbe tardent \u00e0 arriver. En sol peu portant, limiter le temps d\u2019acc\u00e8s au p\u00e2turage \u00e0 4-5 heures\/jour. Pour la rotation au p\u00e2turage tournant : rappel des hauteurs d\u2019herbe entr\u00e9e de parcelle : 10-12 cm herbom\u00e8tre, soit hauteur du bas mollet ; sortie \u00e0 5-6 cm herbom\u00e8tre, \u00e9quivalent talon de botte. Respecter les d\u00e9lais de retour sur les parcelles (18 \u00e0 21 jours au printemps).<\/p>\n

Point de vue de l\u2019\u00e9leveur\u00a0: Fabrice BERNE, \u00e9leveur sur le plateau de \u00ab\u00a0la Vrine\u00a0\u00bb<\/span><\/strong><\/p>\n
“La sortie des vaches au p\u00e2turage doit s\u2019effectuer dans la semaine, A 900 m\u00e8tres d\u2019altitude, la m\u00e9t\u00e9o n\u2019a pas \u00e9t\u00e9 tr\u00e8s favorable depuis un mois (temp\u00e9ratures basses avec des gel\u00e9es, neige et pr\u00e9cipitations). Il a fallu viser juste pour finir les travaux des champs. Les p\u00e2tures n\u2019ont m\u00eame pas \u00e9t\u00e9 hers\u00e9es, mais en l\u2019absence de taupini\u00e8res c\u2019est moins g\u00eanant. L\u2019herbe pousse gentiment avec 30 kg de croissance de MS\/ha\/jour. La parcelle la plus avanc\u00e9e est presque \u00e0 8 cm herbom\u00e8tre.\u00a0 \u00c0 la mise \u00e0 l\u2019herbe la journ\u00e9e, les 40 vaches auront encore 10 kg de foin en p\u00e9riode de transition. Mais finalement, il n\u2019y aura pas de report de stock de foin sortie hiver. La lutte raisonn\u00e9e contre le campagnol terrestre \u00e0 l\u2019automne dernier a permis de retrouver des parcelles propres ce printemps.”<\/p>\n
T\u00e9moignage recueilli par Jean-Marie CURTIL de la Chambre d\u2019Agriculture 25\/90.<\/em><\/p>\n

T\u00e9moignage du GAEC de la Ch\u2019tite famille \u00e0 Cornod<\/strong><\/span><\/p>\n
“Les 40 vaches sont sorties d\u00e9but mars sur les parcelles proches de l\u2019exploitation, avec un acc\u00e8s au b\u00e2timent. Depuis fin mars, le tour sur les autres parcelles a commenc\u00e9. Les vaches ont acc\u00e8s \u00e0 27 parcelles dimensionn\u00e9es pour 2 ou 3 repas selon la p\u00e9riode. Certaines seront \u00e9cart\u00e9es pour la fauche si les croissances deviennent trop importantes.<\/p>\n
La m\u00e9t\u00e9o actuelle complique le choix des parcelles pour sortir les vaches. Les \u00e9leveurs ont choisi la strat\u00e9gie de p\u00e2turer sur les parcelles les plus portantes de l\u2019exploitation afin ne pas d\u00e9grader les autres. Actuellement, il reste une dizaine de parcelles non p\u00e2tur\u00e9es qui atteignent 8 \u00e0 10 cm \u00e0 l\u2019herbom\u00e8tre. La croissance reste encore faible : autour de 23 kg de MS\/ha\/j cette semaine. Les \u00e9leveurs esp\u00e8rent que la m\u00e9t\u00e9o des prochains jours permettra l\u2019acc\u00e8s aux parcelles plus humides et favorisera la croissance dans les semaines \u00e0 venir.<\/p>\n
A ce jour, les vaches ont encore 7,5 kg de foin \u00e0 l\u2019auge, 2,5 kg de regain et environ 4 kg de VL 20. La production moyenne est de 23,9 kg de lait, \u00e0 33.7 g\/kg de TB et 31.3 g\/kg de TP.”<\/p>\n
