Suplementasi Vitamin E dan Selenium dalam Pakan Mengandung Minyak Ikan Lemuru terhadap Organ Dalam Ayam Broiler

Abstract

Penelitian ini bertujuan mengevaluasi efek suplementasi vitamin E dan selenium terhadap persentase bobot organ dalam, saluran pencernaan, dan organ imunitas ayam broiler. Sebanyak 200 ekor ayam broiler strain Cobb digunakan dalam Rancangan Acak Lengkap terdiri atas 4 perlakuan dan 5 ulangan. Perlakuan terdiri atas P0 = Pakan kontrol, P1 = P0 + 200 ppm vitamin E + 0,3 ppm selenium, P2 = P0 + 300 ppm vitamin E + 0,6 ppm selenium, dan P3 = P0 + 400 ppm vitamin E + 0,9 ppm selenium. Hasil penelitian menunjukkan suplementasi 400 ppm vitamin E dan 0,9 ppm selenium dalam pakan mengandung minyak ikan lemuru tidak mempengaruhi (P>0,05) persentase bobot hati, jantung, empedu, pankreas, usus halus, dan sekum. Namun, perlakuan tersebut menghasilkan panjang relatif kolon lebih rendah (P<0,05) dibandingkan perlakuan lainnya. Perlakuan tersebut menghasilkan bobot dan panjang relatif sekum di atas normal serta bobot organ imunitas di bawah normal. Kesimpulan penelitian ini adalah suplementasi 400 ppm vitamin E dan 0,9 ppm selenium dalam pakan mengandung minyak ikan lemuru (P3) tidak berpengaruh negatif terhadap organ dalam, saluran pencernaan, dan organ imunitas. Perlakuan tersebut dapat menurunkan panjang relatif kolon.

This study aimed to evaluate the effects of vitamin E and selenium supplementation on the percentage of internal organ weight, digestive tract, and immune organs in broiler chickens. A total of 200 Cobb strain broiler chickens were used in a Completely Randomized Design with four treatments and five replications. The treatments were P0 = control feed, P1 = P0 + 200 ppm vitamin E + 0.3 ppm selenium, P2 = P0 + 300 ppm vitamin E + 0.6 ppm selenium, and P3 = P0 + 400 ppm vitamin E + 0.9 ppm selenium. Results showed that supplementation with 400 ppm vitamin E and 0.9 ppm selenium in feed containing lemuru fish oil did not affect (P>0.05) the weight of the liver, heart, gallbladder, pancreas, small intestine, and cecum. This treatment resulted in a lower relative colon length (P<0.05) than other treatments. It also caused relatively higher cecum weight and length than normal, and lower immune organ weights. In conclusion, supplementation of 400 ppm vitamin E and 0.9 ppm selenium in feed containing lemuru fish oil (P3) did not negatively affect internal organs, digestive tract, or immune organs. However, this treatment may reduce the relative colon length of broiler chickens.
