Influence of “Chelavite” Mineral Supplement Use on Cadmium and Lead Content in Blood, Wool and Milk of Heavy Cows

Abstract

The purpose of this research was to study the influence of this supplement use on the concentration of cadmium and lead in blood serum, wool and milk of heavy cows. The cows of milking herd of black-and-white breed, of 3-5 years old were the object of research. Their yearly milk production was 6 thousand litters (control and experimental group, each having 15 heads). The cows have been fed according to the balanced ration for heavy cows. The mineral supplement dose was determined according to the instruction for application for cows of experimental group with feed. The curative dose was 0.6 ml for 10 kg of body mass 1 time a day during 30 days. The samples were taken before giving the mineral supplement “Chelavite” and after the course had finished. The device Unicam AAS-939 was used to determine the cadmium and lead content in blood, wool and milk by way of atomic absorption spectrophotometry. It has been found that the cadmium level reduced by 2.35 times, the lead level reduced by 1,5 times in cows blood, the cadmium level reduced by 1.33 times, the lead level reduced by 4.34 times in cows wool, the cadmium level reduced by 2.2 times, the lead level reduced by 3.7 times in cows milk after giving them mineral supplement “Chelavite”. Thus, the application of chelate compounds in form of “Chelavite” for cows reduces concentration of heavy metals such as cadmium and lead. Then this is one of the ways to improve the milk quality.

“Chelavite” Mineral Desteği Kullanımının Kilolu İneklerin Kan, Yapağı ve Sütlerindeki Kadmiyum ve Kurşun İçeriği Üzerindeki Etkisi

Abstract

Bu çalışmanın amacı destek katkı kullanımının kilolu ineklerin kan serumu, yapağı ve sütlerindeki kadmiyum ve kurşun düzeyleri üzerindeki etkisini araştırmaktır. Siyah alaca ırkı, 3-5 yaşlarında sütçü inekler bu çalışmada kullanıldı. Bunların senelik süt üretimleri 6 bin litredir (kontrol ve deney grupları, her birinde 15 baş olmak üzere). İnekler, kilolu inekler için hazırlanan dengeli rasyonlarla beslendi. Mineral destek dozu, deneysel grup inekler için verilen uygulama talimatı doğrultusunda belirlendi. Tedavi edici doz 10 kg’lık vücut ağırlığı için 30 gün süreyle günde bir kez 0,6 ml’idi. Örnekler mineral desteği “Chelavite” verilmeden önce ve tedavi sona erdikten sonra alındı. Kan, yapağı ve sütte kadmiyum ve kurşun miktarlarını atomik absorpsiyon spektrofotometresi yoluyla belirlemek için Unicam AAS-939 cihazı kullanıldı. Mineral desteği “Chelavite” verildikten sonra ineklerin kanındaki kadmiyum düzeyinin 2,35 misli, kurşun düzeyinin 1,5 misli; ineklerin yapağılarındaki kadmiyum düzeyinin 1,33 misli, kurşun düzeyinin 4,34 misli, ineklerin sütlerindeki kadmiyum düzeyinin 2,2 misli, kurşun düzeyinin 3,7 misli azaldığı saptandı. Sonuç olarak, “Chelavite” formundaki şelat bileşiklerinin uygulanması ineklerde kadmiyum ve kurşun gibi ağır metallerin düzeylerini azaltmaktadır. Bu da süt kalitesini iyileştirme yollarından biri olmaktadır.
