Pemberian Minyak Kelapa Sawit dan Minyak Ikan Lemuru dalam Ransum Terhadap Profil Darah dan Persentase Organ Dalam Ayam Broiler

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian minyak kelapa sawit dan minyak ikan lemuru terhadap profil darah dan persentase organ dalam ayam broiler. Penelitian ini menggunakan 200 ekor day old chick (DOC) broiler strain Ross yang dibagi dalam 4 perlakuan dan 5 ulangan. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan perlakuan P0 = ransum mengandung minyak kelapa sawit 3% dan minyak ikan lemuru 0%, P1 = ransum mengandung minyak kelapa sawit 2% dan minyak ikan lemuru 1%, P2 = ransum mengandung minyak kelapa sawit 1% dan minyak ikan lemuru 2%, P3 = ransum mengandung minyak kelapa sawit 0% dan minyak ikan lemuru 3%. Data yang diperoleh dianalisis menggunakan analisis varians (Anova) dan dilakukan uji lanjut Duncan. Peubah yang diamati adalah profil darah, persentase bobot organ dalam, persentase bobot saluran pencernaan dan panjang relatif saluran pencernaan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P>0.05) terhadap jumlah hematokrit, eritrosit, leukosit, dan deferensiasi leukosit (monosit, eosinofil, basofil), persentase bobot jantung, ginjal, empedu, pankreas, bursa fabricius, thimus, proventrikulus, gizzard, panjang relatif duodenum, persentase bobot dan panjang relatif jejunum, ileum, sekum, serta kolon. Pemberian minyak ikan lemuru 3% berpengaruh nyata (P<0.05) meningkatkan nilai hemoglobin, diferensiasi leukosit (heterofil dan limfosit), persentase bobot hati, persentase bobot limfa, serta menurunkan persentase bobot duodenum dan nilai rasio H/L. Disimpulkan bahwa pemberian ransum mengandung minyak ikan lemuru 3% dalam ransum memberikan dampak positif terhadap profil darahm ayam broiler, dapat meningkatkan kadar hemoglobin, limfosit, dan menurunkan tingkat stress dari taraf tinggi ke taraf rendah.

The purpose of this study was to evaluate the effect of giving palm oil and lemuru fish oil on the blood profile and the percentage of internal organs in broiler chickens. This study used 200 Ross broilers day old chick (DOC) is divided into 4 treatments and 5 replications. This research used a completely randomized design (CRD), where the treatments level of palm oil and lemuru fish oil were respectively P0 = rations containing 3% palm oil and 0% lemuru fish oil, P1 = rations containing 2% palm oil and 1% lemuru fish oil, P2 = rations containing 1% palm oil and 2% lemuru fish oil, P3 = rations containing 0% palm oil and 3% lemuru fish oil. The data obtained were analyzed using analysis of variance (Anova) and Duncan's further test was carried out. Some of the observed variables included blood profile, percentage of internal organ weight, percentage of digestive tract weight and relative length of digestive tract. The results showed that the treatment had no significant effect (P>0.05) on the number of hematocrits, erythrocytes, leukocytes, and leukocyte differentiation (monocytes, eosinophils, basophils), the percentage of weight of the heart, kidneys, bile, pancreas, bursa of Fabricius, thymus, proventiculus, gizzard, relative length of duodenum, percentage of weight and relative length of jejunum, ileum, cecum, and colon. Giving 3% lemuru fish oil significantly (P<0.05) increased hemoglobin value, leukocyte differentiation (heterophile and lymphocyte), liver weight percentage, spleen weight percentage, and decreased duodenal weight percentage and H/L ratio value. It was concluded that the provision of rations containing 3% lemuru fish oil in the ration had a positive impact on the blood profile of broiler chickens, could increase hemoglobin, lymphocyte levels, and reduce stress levels from high to low levels.
