PERFORMA DAN KUALITAS SUSU INDUK DOMBA PASCA BERANAK YANG DIBERI RANSUM MENGANDUNG JENIS MINYAK BERBEDA

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh suplementasi minyak ikan lemuru dan minyak biji bunga matahari terhadap performa induk dan kualitas susu pasca beranak. Sebanyak 12 ekor induk domba fase akhir kebuntingan dengan Body Condition Score (BCS) 3,00 dan bobot rata-rata 39,49±4,99 kg digunakan dalam penelitian. Rancangan Acak Kelompok (RAK) diterapkan dengan tiga perlakuan dan empat ulangan, yaitu P0 = ransum konsentrat tanpa minyak, P1 = ransum dengan 6% minyak ikan lemuru, dan P2 = ransum dengan 6% minyak biji bunga matahari. Variabel yang diamati meliputi konsumsi nutrien, pertambahan bobot badan, dan kualitas susu. Hasil menunjukkan suplementasi minyak menurunkan konsumsi lemak kasar dan BETN secara nyata (P<0,01), tetapi tidak berpengaruh (P>0,05) terhadap konsumsi bahan kering, protein kasar, dan serat kasar. Suplementasi meningkatkan persentase recovery bobot badan (P<0,05), namun tidak memengaruhi kualitas susu (P>0,05). Disimpulkan bahwa suplementasi minyak ikan lemuru atau minyak biji bunga matahari 6% mampu memperbaiki recovery bobot badan tanpa menurunkan kualitas susu.

This study aimed to evaluate the effect of lemuru fish oil and sunflower seed oil supplementation on ewe performance and milk quality after lambing. A total of 12 late-pregnant ewes with an average Body Condition Score (BCS) of 3.00 and body weight of 39.49 ± 4.99 kg were used. A Completely Randomized Block Design (CRBD) with three treatments and four replications was applied: P0 = concentrate ration without oil, P1 = concentrate with 6% lemuru fish oil, and P2 = concentrate with 6% sunflower seed oil. Observed variables included nutrient intake, body weight change, and milk quality. The results showed that oil supplementation significantly (P<0.01) reduced crude fat and nitrogen-free extract intake, but had no effect (P>0.05) on dry matter, crude protein, and crude fiber intake. Supplementation significantly improved body weight recovery (P<0.05) compared with the control, while milk quality parameters (fat, SNF, lactose, protein, and specific gravity) were not affected (P>0.05). It is concluded that supplementation of 6% lemuru fish oil or sunflower seed oil in the ration improves postpartum body weight recovery of ewes without compromising milk quality.
