Penyerapan Kadmium Pada Ayam Kampung Yang Diberi Dedak Padi Dalam Ransum – Cadmium Absorption In Native Chicken Fed Rice Bran

Fitat banyak terdapat dalam dedak padi. Senyawa ini dapat mengikat ion multivalensi. Penelitian bertujuan mempelajari penggunaan dedak padi untuk mengurangi penyerapan Cd dalam tubuh ayam kampung. Dua puluh empat ekor ayam kampung jantan umur ±3 bulan dialokasikan dalam rancangan acak lengkap dengan 6 perlakuan. Bobot badan yang digunakan rata-rata 422,08 ± 39 g. Dedak padi dalam ransum perlakuan sebanyak 0% (R0), 10% (R1), 20% (R2), 30% (R3), 40% (R4), 50% (R5) yang digunakan selama 8 minggu. Air minum diberikan ad libitum mengandung 100 ppm Cd. Hasil menunjukkan bahwa perlakuan memberikan perbedaan yang tidak nyata terhadap penyerapan Cd, kadar Cd dalam feses, ginjal dan hati serta bobot ginjal dan hati. Rata-rata Cd dalam ginjal dan hati adalah sebesar 284,24 dan 117,53 ppm. Kesimpulan, penggunaan dedak padi dalam ransum tidak mengurangi penyerapan Cd dalam tubuh. Penggunaan dedak padi dan pencemaran Cd dalam waktu lama dan jumlah besar akan berdampak negatif terhadap ayam kampung.

Phytate is commonly found in high concentration in rice bran. This compound can bind multivalency ions. The purpose of this study was to know the effect of rice bran in native chick diet on Cd absorption. Twenty four native male chicks aged 3 month were randomly divided into six group of treatments. The weight average of chick used in this experiment was 422.08 ± 39 g. The diet treatments were 0% (R0), 10% (R1), 20% (R2), 30% (R3), 40% (R4), 50% (R5) for 8 weeks. Drinking water was given ad libitum containing 100 ppm Cd. The results indicated that those treatments had no significant effect on Cd absorption, Cd concentration in feces, kidney, liver and weight of kidney and liver. Average of Cd in kidney and liver were 284.24 and 117.53 ppm. It was concluded that rice bran in the native chick diet did not reduce Cd absorption. The utilization of rice bran and Cd pollution in long term and in high concentration in the diet gave negative effect on native chick.
