Le retour des pr\u00e9cipitations a donn\u00e9 un coup de fouet \u00e0 la croissance jusqu\u2019alors p\u00e9nalis\u00e9e par le froid et le manque d\u2019eau.

Les \u00e9ventuels exc\u00e8s d\u2019herbe \u00e0 venir en plaine n\u00e9cessiteront de d\u00e9brayer des parcelles destin\u00e9es \u00e0 la fauche (hauteur > 15 cm herbom\u00e8tre) Rappelons qu\u2019avec une ration \u00e0 l\u2019herbe suffisante et de qualit\u00e9 offrant un potentiel 20 \u00e0 25 litres de lait autonome, des \u00e9conomies de concentr\u00e9s sont possibles (objectif\u00a0: 90 \u00e0 120 g\/litre).<\/p>\n

“Les vaches sortent depuis le 25 mars et p\u00e2turent encore\u00a0aujourd’hui uniquement la journ\u00e9e. En effet, les gel\u00e9es sont encore bien pr\u00e9sentes sur la commune avec encore -2\u00b0C\u00a0ce lundi\u00a0matin. Les stocks de fourrages cons\u00e9quents sur l\u2019exploitation permettent de maintenir un niveau de compl\u00e9mentation en fourrages \u00e0 l\u2019auge important (surtout en d\u00e9but de saison) pour s\u2019adapter \u00e0 la disponibilit\u00e9 en herbe et aux conditions climatiques.<\/p>\n

Les vaches consomment actuellement 8kg de fourrages \u00e0 l’auge (50% de foin et 50% de regain de s\u00e9chage). Elles sont toutes compl\u00e9ment\u00e9es avec 2 kg d\u2019orge ainsi qu\u2019une VL 18 et une VL 22 pour les fra\u00eeches (jusqu\u2019\u00e0 3kg selon le niveau de production). La production de lait est de 32kg en moyenne, avec un TB de 37g\/L et un TP de 33,5g\/L.<\/p>\n

La pousse de l\u2019herbe s\u2019est intensifi\u00e9e avec de 44 kg MS\/ha\/jour cette semaine. Cela va permettre un temps de s\u00e9jour un peu plus long sur les parcelles (2 \u00e0 3 jours). Les semaines pr\u00e9c\u00e9dentes, le p\u00e2turage \u00e9tait g\u00e9r\u00e9 \u00ab\u00a0au large\u00a0\u00bb en tournant rapidement.<\/p>\n

Nous esp\u00e9rons pouvoir d\u00e9marrer la campagne de fauche rapidement car 12Ha de p\u00e2ture ont \u00e9t\u00e9 d\u00e9tourn\u00e9s en foin. Une fois fauch\u00e9es, ces parcelles r\u00e9int\u00e8greront le circuit de p\u00e2turage des vaches, ce qui nous permettra plus de flexibilit\u00e9 au p\u00e2turage”.<\/p>\n
