Penambahan Minyak Ikan Lemuru dan Suplementasi Antioksidan Terhadap Respon Stress Domba Jantan Masa Pertumbuhan

Abstract

Penelitian ini bertujuan menganalisis respon stress panas pada domba lokal jantan masa pertumbuhan yang diberi minyak lemuru, vitamin E, dan selenium. Ternak yang digunakan sebanyak 21 ekor domba jantan ekor tipis dengan rata-rata bobot badan 25±2,58 kg dan berumur 9-12 bulan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 7 ulangan. Perlakuan RK = konsentrat kontrol, RL = konsentrat mengandung 6% minyak lemuru, RE- SE = konsentrat mengandung 6% minyak lemuru + Vitamin E 500 IU + Selenium 0,5 ppm. Parameter yang diukur adalah konsumsi nutrien, respon fisiologis, kadar MDA dan kadar SOD. Perlakuan RL dan RE-SE memberikan pengaruh yang sangat nyata lebih rendah (P<0,01) dibandingkan RK pada konsumsi bahan kering, protein kasar, BETN, laju denyut jantung, suhu rektal, kadar MDA, namun memberikan hasil yang lebih tinggi (P<0,01) pada konsumsi lemak kasar dan kadar SOD. Kesimpulan dari penelitian ini bahwa penambahan 6% minyak lemuru yang dikombinasikan dengan suplementasi vitamin E dan selenium menurunkan konsumsi bahan kering, protein kasar, BETN, respon fisiologis dan kadar MDA, namun meningkatkan konsumsi lemak kasar dan kadar SOD pada domba lokal jantan.

This study aimed to analyze the heat stress response of local rams during growth period feed containing lemuru oil, vitamin E, and selenium. The livestock used were 21 rams with an average body weight of 25±2.58 kg and aged 9-12 months. This study used a randomized block design (RCBD) with 3 treatments and 7 replications. Treatment RK = concentrate control, RL = concentrate containing 6% lemuru oil, RE- SE = concentrate containing 6% lemuru oil + Vitamin E 500 IU + Selenium 0.5 ppm. The parameters measured were nutrient consumption, physiological responses, MDA levels and SOD levels. RL and RE-SE treatments had a very significantly lower effect (P<0.01) than RK on dry matter consumption, crude protein, BETN, heart rate, rectal temperature, MDA levels, but gave higher results. (P<0.01) on crude fat consumption and SOD levels. The conclusion of this research is that the addition of 6% lemuru oil combined with vitamin E and selenium supplementation reduced dry matter consumption, crude protein, BETN, physiological responses and MDA levels, but increased crude fat consumption and SOD levels in local rams
