Abstract (2. Language): 
The nitrate contents of forages can increase enought to kill livestocks in some circumstance. High nitrat content of forage important interm of the crops used as forage as well. The most important factors increasing the nitrat content of plants are the excees nitrogen in soil and negative climatic conditions. Nitrate accumulation in plant tissue varied with species to a large extent. Drying process do not decrease the nitrat content of fresh plant materials. But, it is possible to decrease the nitrat contents of forage in 50% percentage with sillage process. The forages with high nitrat contents has acute and chronic effect on livestock health. Therefore, maximum attention should be paid while the forage up to 1000 ppm nitrat contents are used.
Abstract (Original Language): 
Bazı durumlarda yem bitkilerinin nitrat içerikleri, hayvanları öldürecek düzeye çıkabilir. Yüksek nitrat problemi, yem kaynağı olarak kullanılan sap-saman açısından da önem taşımaktadır. Bitkilerdeki nitrat içeriğini artıran en önemli faktörler, toprakta aşırı azot varlığı ve büyümeyi engelleyen olumsuz hava şartlarıdır. Nitrat biriktirme açısından bitki türleri arasında büyük farklılık vardır. Yeşil materyalin kurutulması ile nitrat içeriği azalmaz. Ancak silolama ile yemin nitrat içeriği yarı yarıya düşürülebilir. Yüksek nitrat içeren yemler, hayvanlarda akut ve kronik etki yaparlar. Bu nedenle, nitrat içeriği 1000 ppm'den daha fazla olan yemlerin hayvanlara verilmesinde çok dikkatli olmak gerekir.
