About the Book

Une expérience en plein champ a été menée à la station expérimentale agricole de Gizeh, ARC, Égypte, pendant les saisons 2012 et 2013 afin d'étudier l'effet de différentes sources et doses d'engrais azotés sur le rendement en fourrage frais et sec du sorgho du Soudan, les composants chimiques et l'accumulation de nitrate et de nitrite dans la plante. Il peut être recommandé de fertiliser les plants de sorgho du Soudan avec 100 kg N/fed sous forme de sulfate d'ammonium afin de maximiser leur rendement fourrager et de réduire l'accumulation de nitrate et de nitrite dans la plante dans les conditions environnementales du gouvernorat de Gizeh, en Égypte. Une expérience biologique a été menée pour étudier l'effet de différents niveaux de nitrate dans l'alimentation des lapins mâles Rex. En conclusion, les lapins soumis à ces études peuvent tolérer 0,73 % de nitrate (1 % de nitrate de sodium) dans leur alimentation sans effet négatif significatif. La plupart des résultats obtenus avec 1,46 % de nitrate (2 % de nitrate de sodium) et tous les résultats obtenus avec 2,19 % de nitrate (3 % de nitrate de sodium) ont eu un effet toxique sur la croissance, la digestibilité des nutriments, les paramètres sanguins et la structure histologique des organes internes des lapins.
