Nous l'avons d\u00e9j\u00e0 dit et nous le r\u00e9p\u00e9tons : le colostrum est le repas le plus important dans la vie d'un veau laitier. Les veaux naissent sans un syst\u00e8me immunitaire pleinement fonctionnel et d\u00e9pendent exclusivement du transfert passif de l'immunit\u00e9 provenant de la consommation de colostrum au cours de la premi\u00e8re ou des deux premi\u00e8res t\u00e9t\u00e9es apr\u00e8s la naissance. Cela permet au veau de lutter contre les maladies et autres probl\u00e8mes immunitaires pendant les trois ou quatre premi\u00e8res semaines de sa vie.<\/p>\n\n\n\n

En savoir plus : Importance du colostrum pour les veaux<\/em><\/a><\/em><\/p>\n\n\n\n

Pour obtenir un transfert passif, les veaux doivent consommer au moins 150 grammes d'immunoglobuline G (IgG). Le fait que les veaux n'obtiennent pas un transfert passif de l'immunit\u00e9 en ne consommant pas suffisamment d'immunoglobulines G (IgG) provenant du colostrum a plusieurs cons\u00e9quences \u00e0 court et \u00e0 long terme :<\/p>\n\n\n\n

  1. Ils sont plus susceptibles de tomber malades ou de mourir.<\/li>
  2. Ils ne grandiront pas aussi bien pendant les premiers mois de leur vie.<\/li>
  3. Elles ont moins de chances de vivre jusqu'\u00e0 la fin de leur deuxi\u00e8me lactation.<\/li>
  4. Elles produisent moins de lait pendant la premi\u00e8re et la deuxi\u00e8me lactation.<\/li>
  5. Vos factures de v\u00e9t\u00e9rinaire peuvent augmenter d'environ $10 par veau.<\/li><\/ol>\n\n\n\n

    Pour augmenter la probabilit\u00e9 que vos veaux b\u00e9n\u00e9ficient d'un transfert passif de l'immunit\u00e9, la premi\u00e8re \u00e9tape consiste \u00e0 tester la qualit\u00e9 du colostrum de votre vache apr\u00e8s la premi\u00e8re traite suivant le v\u00ealage. Cela ne prend que 30 secondes et tout ce dont vous avez besoin est un r\u00e9fractom\u00e8tre Brix ou un colostrom\u00e8tre. Une fois que vous connaissez la qualit\u00e9 du colostrum de votre vache, vous pouvez d\u00e9cider si vous pouvez le donner en toute s\u00e9curit\u00e9 ou si vous devez le compl\u00e9ter ou le remplacer par une poudre de colostrum, telle que Premolac\u00ae<\/sup><\/a>. En d'autres termes, nous devons savoir \u00e0 quoi nous avons affaire !<\/p>\n\n\n\n

    Une nouvelle approche pour obtenir un transfert passif de l'immunit\u00e9<\/strong><\/h2>\n\n\n\n
    1. Autrefois, le transfert passif de l'immunit\u00e9 chez les veaux laitiers \u00e9tait consid\u00e9r\u00e9 comme un test de r\u00e9ussite ou d'\u00e9chec. \u00c0 l'\u00e9poque, nous testions le colostrum \u00e0 l'aide d'un r\u00e9fractom\u00e8tre Brix avant la premi\u00e8re t\u00e9t\u00e9e du veau afin de prendre l'une des deux d\u00e9cisions suivantes : Brix > ~24% - le colostrum est de bonne qualit\u00e9 et a \u00e9t\u00e9 donn\u00e9 aux veaux.<\/li>
    2. Brix < ~24% - votre colostrum n'\u00e9tait PAS de bonne qualit\u00e9 et a \u00e9t\u00e9 jet\u00e9 ou utilis\u00e9 \u00e0 d'autres fins et un substitut de colostrum contenant 150 g d'IgG peut avoir \u00e9t\u00e9 utilis\u00e9.<\/li><\/ol>\n\n\n\n

      Toutefois, au cours de l'ann\u00e9e \u00e9coul\u00e9e, l'USDA a publi\u00e9 lignes directrices<\/a> qui recommandent une approche plus diff\u00e9renci\u00e9e pour d\u00e9terminer le statut immunitaire du veau et ont augment\u00e9 le seuil \u00e0 atteindre pour obtenir un transfert passif optimal.<\/p>\n\n\n\n

      Les nouvelles lignes directrices peuvent sembler d\u00e9courageantes, mais elles peuvent entra\u00eener des am\u00e9liorations massives de la mortalit\u00e9 et de la morbidit\u00e9 dans les exploitations agricoles. Il existe une nouvelle option pour aider les producteurs \u00e0 respecter ces nouvelles normes : compl\u00e9ter le colostrum maternel avec de la poudre de colostrum.<\/p>\n\n\n\n

      Maintenant que la suppl\u00e9mentation en poudre de colostrum en plus du colostrum maternel est reconnue comme une option viable pour aider les veaux \u00e0 obtenir un transfert passif, vous pouvez utiliser un r\u00e9fractom\u00e8tre Brix pour faire l'un des trois choix suivants :<\/p>\n\n\n\n

      \"\"<\/figure>\n\n\n\n

      Comme vous pouvez le constater, si votre r\u00e9fractom\u00e8tre Brix indique entre 18% et 24%, ce colostrum n'est plus jet\u00e9, mais plut\u00f4t am\u00e9lior\u00e9 avec un suppl\u00e9ment de colostrum. Cette approche pr\u00e9sente deux avantages principaux :<\/p>\n\n\n\n

      1. Le colostrum qui \u00e9tait auparavant jet\u00e9 peut d\u00e9sormais \u00eatre utilis\u00e9 d\u00e8s la premi\u00e8re t\u00e9t\u00e9e, ce qui rend l'utilisation du colostrum plus efficace dans l'exploitation.<\/li>
      2. Les veaux qui auraient auparavant re\u00e7u un substitut de colostrum re\u00e7oivent d\u00e9sormais un suppl\u00e9ment de colostrum (avec moins d'IgG), ce qui r\u00e9duit le co\u00fbt par veau.<\/li><\/ol>\n\n\n\n

        Il a \u00e9t\u00e9 d\u00e9montr\u00e9 que cette strat\u00e9gie aide les veaux \u00e0 atteindre des niveaux plus \u00e9lev\u00e9s de transfert passif de l'immunit\u00e9. En fait, des donn\u00e9es r\u00e9centes de l'universit\u00e9 de Penn State ont montr\u00e9 qu'un suppl\u00e9ment de colostrum de \"qualit\u00e9 moyenne\" am\u00e9liorait de mani\u00e8re significative le statut immunitaire et aidait les veaux \u00e0 atteindre les nouvelles attentes en mati\u00e8re de transfert passif. En adoptant cette strat\u00e9gie, vous avez plus de chances d'obtenir un transfert passif \"bon\" ou \"excellent\" tout en utilisant une plus grande partie de votre colostrum et en gardant plus d'argent dans votre poche.<\/p>\n\n\n\n

        Compl\u00e9ter avec le colostrum en poudre Premolac<\/strong><\/h2>\n\n\n\n

        Toutes les poudres de colostrum ne se valent pas. De nombreuses poudres de colostrum contiennent de la graisse et de la cas\u00e9ine en plus des IgG, ce qui entra\u00eene un taux d'alimentation beaucoup plus \u00e9lev\u00e9. La graisse et la cas\u00e9ine rendent \u00e9galement le m\u00e9lange plus difficile, vous obligent \u00e0 ajouter de l'eau et peuvent m\u00eame interf\u00e9rer avec l'absorption des IgG par les veaux.<\/p>\n\n\n\n

        En revanche, le colostrum Premolac utilise la technologie PathWhey\u2120 qui \u00e9limine la graisse et la cas\u00e9ine pour en faire un concentr\u00e9. Il en r\u00e9sulte un produit qui passe en solution beaucoup plus facilement et permet un taux d'alimentation plus faible, ce qui en fait une solution plus rentable pour vos veaux. Nous avons constat\u00e9 que le colostrum Premolac, lorsqu'il est utilis\u00e9 comme suppl\u00e9ment, am\u00e9liore de mani\u00e8re significative les IgG s\u00e9riques \u00e0 24 heures et augmente l'efficacit\u00e9 avec laquelle les IgG sont absorb\u00e9es.<\/p>\n\n\n\n

        Une ferme am\u00e9ricaine avec laquelle j'ai r\u00e9cemment travaill\u00e9 n'utilisait pas une grande partie de son colostrum. Elle donnait son colostrum de haute qualit\u00e9 et jetait tout ce qui \u00e9tait de qualit\u00e9 moyenne ou inf\u00e9rieure. En introduisant le concept de suppl\u00e9mentation du colostrum maternel de qualit\u00e9 moyenne avec Premolac, nous avons pu les aider \u00e0 r\u00e9duire leurs co\u00fbts et \u00e0 am\u00e9liorer la sant\u00e9 des veaux presque du jour au lendemain.<\/p>\n\n\n\n

        Une autre ferme avec laquelle j'ai travaill\u00e9 en Asie avait une tr\u00e8s mauvaise gestion du colostrum. Elle perdait environ 20% de ses veaux chaque ann\u00e9e. Outre la mise en \u0153uvre de nouvelles mesures de bios\u00e9curit\u00e9 et de nettoyage, nous leur avons demand\u00e9 de commencer \u00e0 administrer du Premolac. Lorsque nous avons revu la ferme six mois plus tard, elle n'avait pas perdu un seul veau au cours de cette p\u00e9riode.<\/p>\n\n\n\n

        Prenez 30 secondes pour am\u00e9liorer la gestion du colostrum d\u00e8s aujourd'hui<\/h2>\n\n\n\n

        La nouvelle approche de la suppl\u00e9mentation en colostrum ne demande pas beaucoup de travail suppl\u00e9mentaire, mais plut\u00f4t un nouveau processus de r\u00e9flexion. En prenant 30 secondes pour v\u00e9rifier la qualit\u00e9 du colostrum de vos vaches \u00e0 l'aide d'un r\u00e9fractom\u00e8tre Brix, vous pouvez d\u00e9terminer les prochaines \u00e9tapes de votre strat\u00e9gie en mati\u00e8re de colostrum, ce qui pourrait vous permettre d'\u00e9conomiser de l'argent et d'am\u00e9liorer la sant\u00e9 de vos veaux.<\/p>\n\n\n\n
