Çok Yönlü Hayvan Yetiriciliğinde Karma Yem ve Yem Hammaddelerinden Kaynaklanan Olumsuzluk Faktörlerinin Araştırılması. 3. Türkiye'de Üretilen Veya İthal Edilen Yem veYem Hammaddelerinde Toksik Etkili Mineral Madde İçeriklerinin Araştırılması

Çalışmada Türkiye'de üretilen veya ithal edilen bazı yem hammaddeleri ve karma yemlerde zehirliliği bulunan bazı mineral madde miktarlarının ortaya konulması amaçlandı. Bunun için, Nisan 1993-Nisan 1996 dönemi arasında Türkiye'nin 7 bölgesinde faaliyette bulunan 48 yem fabrikasından düzenli aralıklarda 420'si karma yem ve 780'i yem hammaddesinden oluşan toplam 1200 örnek sağlandı. Bu maddelerde kurşun, bakır, demir, manganez, magnezyum ve nikel yönünden analiz yapıldı. Organik madde kısmının kuru külleştirmeyle yıkımianmasını takiben, örneklerin mineral madde düzeyleri ASS ile ölçüldü . Analiz edilen yem hanunaddelerinde 0.17-11 .24 ppm arasında kurşun, 0.21-17.10 ppm arasında bakır, 2 . 64-127.80 ppm arasında demir, 1.05-53.08 ppm arasında manganez, 601-ı994 ppm arasında mağnezyum ve 0.05-7.07 ppm arasında nikel; karma yemlerde O. 14-14.87 ppm arasında kurşun, 0.40-19.25 ppm arasında bakır,l.34- ıo9 . 93 ppm arasında demir, 1.35-51.77 ppm arasında manganez, 613-2023 ppm arasında magnezyum ve O. ı4-6.46 ppm arasında nikel bulunduğu belirlendi. Analiz bulgulannın değerlendirilmesi ile yem ve yem hammaddelerindeki mineral madde düzeylerinin hayvanlar için kısa veya uzun süreli dönemde herhangibir zehirlenıneye yol açacak boyutta olmadığı ; aslında, özellikle bakır,demir vemanganez yönlerinden yemierin desteklenmesi gerektiği sonucuna varıldı.

Investigation Of Unfavourable Factors Occurıng In Feedstuffs and Mixed Feeds In Multipurpose Animal Rearing: 3. Investıgatıon Of Toxic Mineral Content In Feedstuffs and Mixed Feeds Produced Or Imported In Turkey

The study was performed to determine the amounts of toxic minerals in certain feeds and feedstuffs, imported or produced in Turkey. Therefore, 1200 samples consisting of 420 mİxed feeds and 780 feedstt_ıffs were obtained regularly from 48 factory working in 7 region ofTurkey, between April 1993 to April 1996 . The samples were subjected to the level of lead, iron, cop per, manganese,magnesium and nickel. Following the buming of organic matter of the samples in the dry ash oven, the mineral levels were determined by ASS. Among feedstuffs, level oflead in between 0 .17-11.24 ppm, copper in between 0 .21-17.1 O ppm, iron in between 2.64-127.80 , manganese in between 1.05-53.08 ppm. magnesium in between 601-ı994 ppm and nickel in between 0.06-7.07 ppm were observed. As for mİxed feeds those levels in the same order were also observed as follows: 0 . 14-14 . 87 ppm, 0.40-ı9.25 ppm, 1.34-109.93 ppm, 1.35-51.77 ppm, 613-2023 ppm and 0.14-6.46 ppm. Interpretation of the results, ıt was concluded that the levels of mineral substances had not been hazardous in short and long period, and those feeds should have been suplemented with copper, iron and manganese.
