Pengaruh Penggunaan Minyak Ikan Lemuru dan Minyak Sawit pada Taraf Berbeda terhadap Kadar Kolesterol dan Malondialdehid (MDA) Ayam Broiler

Abstract

Penelitian bertujuan menganalisis pengaruh penggunaan minyak ikan dan sawit dalam pakan terhadap kadar kolesterol dan malondialdehid (MDA) daging broiler. Penelitian menggunakan 200 ekor ayam broiler yang dipelihara selama 5 minggu dan dibagi ke dalam 20 petak kandang. Pola penelitian menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Taraf perlakuan ransum adalah P0 (minyak ikan 0% dan minyak sawit 3%), P1 (minyak ikan 1% dan minyak sawit 2%), P2 (minyak ikan 2% dan minyak sawit 1%) dan P3 (minyak ikan 3% dan minyak sawit 0%). Peubah yang diamati adalah kadar kolesterol dan malondialdehid daging dada. Hasil penelitian menunjukkan penggunaan minyak ikan 2% dan minyak sawit 1% (P2) menghasilkan kadar kolesterol daging dada paling rendah. Kadar MDA berkisar 0,647 ± 0,044 mg kg-1 sampai dengan 0,726 ± 0,064 mg kg-1. Simpulan hasil penelitian menunjukkan bahwa penggunaan 2% minyak ikan dan 1% minyak sawit (P2) dalam ransum menurunkan kadar kolesterol 38,85% dari P0 dan keempat perlakuan tidak berpengaruh terhadap kadar MDA ayam broiler.

The research aimed to analyze utilization of fish oil and palm oil in feed on broiler meat cholesterol and malondialdehyde (MDA) content. Research used 200 broiler chickens reared for 5 weeks and divided to 20 units of experiments. Research design using complete random design with 4 treatments and 5 replications. Levels of ration experiments were P0 (palm oil 3% and fish oil 0%), P1 (palm oil 2% and fish oil 1%), P2 (palm oil 1% and fish oil 2%) and P3 (palm oil 0% and fish oil 3%). Observed variables were breast meat cholesterol and malondialdehyde content. Results showed that utilization of fish oil 2% and palm oil 1% (P2) had the lowest breast meat cholesterols content. The MDA content ranges around 0.647 ± 0.044 mg kg-1 to 0.726 ± 0.064 mg kg-1. In conclusion the utilization of 2% fish oil and 1% of palm oil (P2) on feed decreases cholesterol content 38,85% than P0 and all of the treatments have no effect against broiler MDA content.
