Using X-ray Fluorescence Technique Propagation of Chromium (Cr) from Poultry Feeds to Different Parts of Chicken including her Eggs†

Abstract

This paper presents the detection and propagation of heavy metals, particularly Chromium (Cr), in poultry in the Rajshahi area using the X-ray fluorescence (XRF) technique. The investigation was done to assess the possible transfer of heavy metals from poultry feeds to chicken meat. The study was carried out in the Rajshahi including collection feeds to chicken. It was found that a considerable amount of Cr was confirmed in all four locally produced poultry feeds and also assured that the Cr contained in chicken propagates to the chicken meat and egg. Among the four most widely used feeds in the Rajshahi region, “Adorsho Feed (Pabna)” shows a maximum Cr concentration of 17.3 ppm. Six different parts of the chicken for different ages which were grown by “Adorsho Feed” were considered for further study. About 4.3 ppm of Cr was found in Yolk whereas a little small about 2.7 ppm was found in the albumin. The average value of Cr in six parts of chicken remains almost the same, which is 3.74 ppm, irrespective of age. It is found that about 21.6% of Cr was propagated from the poultry feed to chicken flesh and also about 90% of Cr was propagated from the chicken to egg. The experimental results indicate that the investigation of the transmission of heavy metals like Cr from feed to egg and poultry is efficiently evaluated by using X-ray Fluorescence Technique.
