Une première région n+ et une région de type p (64) sont situées dans le puits n (60). Les régions n+ et de type p sont éloignées les unes des autres et connectées électriquement, de façon à constituer l'anode du redresseur. Le dispositif de protection contre les décharges électriques comporte également des diodes de niveau (26, 27) entre les circuits d'alimentation périphériques et intérieurs, ainsi qu'une nouvelle résistance de puits permettant de répartir la résistance, afin d'augmenter la protection du circuit tampon de sortie.

Abstract: La présente invention concerne une méthode permettant d'obtenir un procédé plus efficace et plus économique d'alimentation de ruminants au moyen d'un régime faible en protéines brutes tout en réalisant le même taux de rendement laitier et de composants laitiers que pour des ruminants bénéficiant d'un régime protéique normal. Plus particulièrement, le procédé implique d'alimenter des ruminants avec un supplément de nourriture animale comprenant au moins une protéine soustraite à la dégradation ruminale en combinaison avec un régime plus faible en protéines brutes. Ce procédé permet d'obtenir une approche unique de formulation nutritionnelle en ce qu'il permet jusqu'à 50 % de réduction d'ingestion protéique brute tout en maintenant l'alimentation protéique intestinale et le taux de rendement en composants laitiers. Il en résulte alors une réduction des pertes azotées dans les urines animales et une réduction des coûts d'alimentation.
