Investigation of the levels of nitra te, nitrite, tannin and eyanide which are im portant from the po int of view of animal health and productivity in domestic and imported feed and feedstuff samples

Öz

The levels of nitrate, nitrite, tanin and cyanide which may cause deleterious effects to livestock, were determined in feeds and feedstuffs . The determined levels of nitrate, nitrite in feeds and feedstuffs for livestock, and tannin for large animals would not to cause health problems However, same of the feeds and feedstuffs, which were contained harmful levels of tannin, would exceeded the tolerance limits ( 10 ppm for chick feeds, 50 ppm for other feeds and feedstuffs) the determined levels of cyanide in some feeds and feedstuffs which would result any hazard to animals, but levels of cyanide in 3 cotton seed bagasses would give rise health problems for animals (above 200 ppm cyanide).

Türkiye'de Üretilen veya İthal Edilen Yem ve Yem Hammaddelerinin Hayvan Sağlığı ve Verimliliği Yönünden Önem Taşıyan Nitrat-Nitrit, Tannik Asit ve Siyanür İçerikleri Üzerinde Araştırmalar

Öz

Bu çalışmada, yem ve yem hammaddelerinde, hayvanlarda istenmeyen etkilere yol açan olumsuzluk faktörlerinden nitrat, nitrit, tanen ve siyanür düzeyleri ölçülmüştür. Yem ve yem hammaddelerinde ölçülen nitrat ve nitrit düzeyleri tüm hayvanlarda, tanen düzeyleri de büyükbaş hayvanlarda sağlık problemi oluşturacak boyutta bulunmamıştır. Bununla beraber, bazı yem ve yem hammaddelerinde bulunan tanen düzeylerinin kanatlılarda istenmeyen etkilere yol açabilecek seviyede olduğu tespit edilmiştir. Bazı yem ve yem hammaddelerinde ölçülen siyanür düzeyleri tolerans limitlerini (civciv yemi için lüppm, diğer yem ve yem hammaddeleri için 50 ppm) aştığı halde, hayvanlar yönünden tehlikeli olabilecek seviyelerde olmadığı , bununla beraber sadece 3 pamuk tohumu küspesinde ölçülen siyanür düzeylerinin (200ppm' in üzerinde) hayvanlarda sağlık sorunlarına yol açabileceği sonucuna varılmıştır.
