Avec le retour des pr\u00e9cipitations et de temp\u00e9ratures plus \u00e9lev\u00e9es, bien que fluctuantes\u2026, les croissances d\u2019herbe au p\u00e2turage sont relanc\u00e9es et doivent permettre de reprendre une rotation plus adapt\u00e9e sur les parcelles (retour tous les 18 \u00e0 21 jours au printemps). Pour bien valoriser l\u2019herbe, rappelons les hauteurs d\u2019entr\u00e9e (10-12 cm herbom\u00e8tre, \u00e9quivalent bas-mollet) et celles de sortie\u00a0 de parcelle (5-6 cm herbom\u00e8tre, \u00e9quivalent talon de la botte). En conditions tr\u00e8s humides, pensez \u00e0 pr\u00e9server le potentiel des p\u00e2tures pour la saison (chemins d\u2019acc\u00e8s, points d’eau, temps de pr\u00e9sence plus restreint si besoin\u2026).<\/p>\n\"\"\n

“J’ai loup\u00e9 le cr\u00e9neau en mars pour l\u00e2cher donc les 90 VL sont sorties d\u00e9but avril. La transition a \u00e9t\u00e9 courte puisqu’elles \u00e9taient dehors jour et nuit au bout de 2-3 jours \u00e0 l’herbe. J’avais peur d’\u00eatre d\u00e9bord\u00e9 par l’herbe mais la p\u00e9riode de gel a bien calm\u00e9 la pousse. Le 14\/04 on \u00e9tait \u00e0 32 kg de lait\/VL (mois moyen du troupeau : 5 mois), on a diminu\u00e9 l’ensilage d’herbe progressivement (plus du tout dans la ration depuis le 15\/04). Elles ont 8 kg brut de ma\u00efs ensilage, 4 kg brut de ma\u00efs \u00e9pi, 4 kg de concentr\u00e9s et 1 kg de tourteau en plus des 30 ares\/VL au p\u00e2turage. On a perdu en TB (moins de 38) et en TP (moins de 36) pendant la p\u00e9riode de froid d’o\u00f9 l’importance de maintenir de la fibre.”<\/p>\n

“Mes 40 vaches p\u00e2turent sur\u00a0une vingtaine d\u2019hectare, d\u00e9coup\u00e9s en parcelles de 0.7 ha, en fonction du potentiel de pousse. Chacune d\u2019elle permettent de faire 2 repas. Je garde les plus proches du b\u00e2timent en parcelles de nuit pour permettre aux vaches de rentrer si elles le souhaitent. Les plus \u00e9loign\u00e9es sont celles de jours. Du foin reste accessible dans le b\u00e2timent et un minimum de concentr\u00e9 est distribu\u00e9 aux animaux, le but \u00e9tant d\u2019\u00eatre le plus \u00e9conomique possible sur la p\u00e9riode de p\u00e2turage. L\u00e2ch\u00e9es fin mars, les vaches produisent en moyenne 27 kg pour moins de 3kg de concentr\u00e9s distribu\u00e9s actuellement.<\/p>\n

Si la pousse de l\u2019herbe a eu du mal \u00e0 se faire en d\u00e9but de saison, le prochain d\u00e9fi sera de ne pas se laisser d\u00e9passer. Des parcelles actuellement p\u00e2tur\u00e9es vont probablement sortir du circuit de p\u00e2turage pour rejoindre les champs de foin, si la m\u00e9t\u00e9o le permet\u00a0!”.<\/p>\n
