Rep\u00e8res conduite du troupeau : du 8 au 15 mai 2023<\/strong><\/p>\n\"\"\n
 <\/p>\n
Point de vue des \u00e9leveurs du GAEC de la BARRE \u00e0 la Barrre<\/strong><\/span><\/p>\n
“Le GAEC compte 82 vaches trayantes qui p\u00e2turent sur 42 ha, depuis fin mars. Cette surface est d\u00e9coup\u00e9e en 7 parcelles, en cl\u00f4ture fixe, qui font entre 5ha et 8ha soit p\u00e2turable en 3 \u00e0 5 jours. En ce moment, les vaches rentrent dans la parcelle \u00e0 12 cm puis ressorte \u00e0 6 cm. La pousse d\u2019herbe pr\u00e9coce est un atout majeur pour avancer la date \u00e0 la mise \u00e0 l\u2019herbe et g\u00e9rer les stocks fourrager.<\/p>\n
Pour effectuer un p\u00e2turage pr\u00e9coce, l\u2019acc\u00e8s aux p\u00e2tures est tr\u00e8s important, les chemins mis en place ont permis d\u2019\u00e9viter une destruction des parcelles et des boiteries \u00bb. Les vaches produisent 27,1 kg au contr\u00f4le r\u00e9alis\u00e9 le 15 mai. Elles consomment en plus de l\u2019herbe p\u00e2tur\u00e9e, 1 kg de foin, 4,6 kg de VL et 1 kg de tourteau. Ceci correspond \u00e0 292 g de concentr\u00e9s par litre de lait produit.”<\/span><\/p>\n
Propos recueillis par L\u00e9a STACHOWSKI, conseill\u00e8re d\u2019\u00e9levage \u00e0 GEN\u2019IAtest.<\/em><\/p>\n

T\u00e9moignage de Cl\u00e9mence au GAEC des Hortensias \u00e0 Saint-Laurent-en-Grandvaux<\/strong><\/span><\/p>\n
“Les 41 vaches p\u00e2turent jour et nuit sur 25 ha d\u00e9coup\u00e9s en 16 parcelles. Elles produisent 30.6 kg de lait avec 3.8 kg de VL16. D\u00e8s le d\u00e9but de la saison, la croissance de l\u2019herbe a \u00e9t\u00e9 exceptionnelle : lors du d\u00e9primage, pour la premi\u00e8re fois, les vaches n\u2019ont pas pu passer dans toutes les parcelles car l\u2019herbe poussait trop rapidement.<\/p>\n
Deux grandes parcelles ont \u00e9t\u00e9 \u00e9cart\u00e9es imm\u00e9diatement pour la fauche. Actuellement, la pousse de l\u2019herbe est toujours excellente (96 kg de MS\/ha\/j). Avec cette croissance, l\u2019enjeu pr\u00e9sent est de d\u00e9cider s\u2019il faut \u00e9carter d\u2019autres parcelles pour la fauche, afin de ne pas se laisser d\u00e9passer et d\u2019avoir du regain \u00e0 faire p\u00e2turer plus tard dans la saison ; ou s\u2019il vaut mieux conserver l\u2019herbe pour la p\u00e2ture afin d\u2019anticiper un \u00e9ventuel manque.<\/p>\n
Par ailleurs, la gestion des parcelles est compliqu\u00e9e car les grandes quantit\u00e9s d\u2019eau re\u00e7ues font que celles-ci s\u2019abiment plus vite.Il n\u2019est pas possible de laisser les vaches plus de trois jours dans une m\u00eame parcelle.”<\/span><\/p>\n
