L\u2019agriculteur choisit de nourrir son troupeau avec le r\u00e9gime \u00ab\u00a0herbe\u00a0\u00bb. Il a environ 43 vaches et donc 13 g\u00e9nisses et 26 veaux. Il cultive 26 ha de bl\u00e9, 4 ha de ma\u00efs et 19 ha de prairie. Toute sa production de bl\u00e9 est vendue.<\/p>\n

V\u00e9rifications du nombre d\u2019animaux pr\u00e9sents et des taux de renouvellement et de r\u00e9forme :<\/strong><\/p>\n

0.3 * 42.857\u00a0 = 12.857
\n0.6 * 42.857 = 25.714<\/p>\n

V\u00e9rifications si les besoins alimentaires sont bien couverts par la production des surfaces cultiv\u00e9es :<\/strong><\/p>\n

Avec les 19ha de prairie il produit\u00a0:

Pour nourrir ses animaux il a besoin de\u00a0:
