Une internaute qui a vu l’\u00e9mission Thema d’Arte du 23 octobre, consacr\u00e9e \u00e0 la PAC (La fin des paysans? <\/em>et On ne pr\u00eate qu’aux riches<\/em>) s’interroge sur une s\u00e9quence o\u00f9 l’on voit une vache laiti\u00e8re qui a dans le flanc gauche, au niveau de la panse, une esp\u00e8ce d’appareil en forme de tube dans lequel l’\u00e9leveur passe le bras.<\/p>\n

Elle nous dit, un peu surprise, semble t-il (et il y a de quoi), ce qu’elle a vu: \u00ab Un homme s\u2019approche du flanc d\u2019une vache avec \u00e0 la main une sorte de container. L\u2019homme plonge la main, puis le bras\u2026.! (jusqu\u2019au coude) dans le flanc de l\u2019animal, par une sorte de hublot taill\u00e9 \u00e0 m\u00eame la chair. Comme un hublot de machine \u00e0 laver, par lequel il introduit le container\u00a0\u00bb.<\/p>\n

Cette internaute nous demande ce que cette sc\u00e8ne a de r\u00e9el.<\/p>\n

R\u00e9ponse: cette sc\u00e8ne est bien r\u00e9elle mais pas courante du tout. Renseignements pris aupr\u00e8s du cabinet v\u00e9t\u00e9rinaire de Fitilieu (Is\u00e8re), il s’agit d’une intervention exp\u00e9rimentale, qui se pratique depuis longtemps \u00e0 l’INRA, notamment, dans le cadre d’exp\u00e9rimentations alimentaires, mais aussi dans certains tr\u00e8s grands \u00e9levages laitiers, soucieux de contr\u00f4ler au mieux et d’am\u00e9liorer la production laiti\u00e8re. Mais \u00e7a n’a rien d’ordinaire.<\/p>\n

\"vache_coupe.gif\"<\/p>\n

Que notre lectrice se rassure, donc. Ce qu’elle a vu ne se pratique qu’\u00e0 des fins exp\u00e9rimentales et scientifiques et ne concerne qu’un animal du troupeau, pris comme r\u00e9f\u00e9rence. Le but, rappelons-le, est de mesurer le taux de productivit\u00e9 de l’animal, son rendement en fonction de son alimentation. Les vaches \u00e0 lait sont prises… pour des vaches \u00e0 lait! Ca tombe sous le sens. Autrement dit, on fait tout ce qu’il faut pour que leur rendement soit optimum.<\/p>\n

Le syst\u00e8me digestif des ruminants est un sujet de recherche permanent. De nombreuses recherches ont \u00e9t\u00e9 effectu\u00e9es en rapport avec le rumen (la panse) des bovins; on essaie d\u2019en apprendre plus sur la vitesse de passage des aliments, le synchronisme \u00e9nergie-prot\u00e9ine, la digestibilit\u00e9 de diff\u00e9rents aliments, notamment pour combattre l’acidose lente qui a des effets d\u00e9favorables sur la valorisation de la ration et sur la qualit\u00e9 des produits. La biologie ruminale est un domaine qui devient de plus en plus pointu. Et la production laiti\u00e8re du XXIe si\u00e8cle de plus en plus efficace.<\/p>\n","protected":false},"excerpt":{"rendered":"
