ABSTRAK:Penelitian ini bertujuan untuk mengkaji pengaruh lama waktu pemberian Spirulina platensis. sebagai prebiotik terhadap profil darah merah ayam broiler. Materi yang digunakan pada penelitian ini adalah 240 ekor day old chick (DOC) ayam broiler dengan bobot awal rata-rata 42,015 ± 0,219 g. Percobaan dirancang berdasar Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Perlakuan yang diterapkan yaitu T0 (Pakan Basal + 0,04% Zinc Bacitracin), T1 (Pakan Basal + 1% Spirulina platensis selama 7 hari pemberian), T2 (Pakan Basal + 1% Spirulina platensis selama 21 hari pemberian) dan T3 (Pakan Basal + 1% Spirulina platensis selama 35 hari pemberian). Variabel yang diukur meliputi total eritrosit, kadar hemoglobin, persentase hematokrit, serta nilai indeks eritrosit (MCV, MCH, MCHC). Data dianalisis dengan uji ragam (uji F) dan apabila terdapat perbedaan nyata maka dilanjutkan dengan uji wilayah ganda Duncan. Hasil penelitian menunjukkan adanya pengaruh (P<0,05) antar perlakuan terhadap rataan total eritrosit, serta tidak ada pengaruh (P>0,05) antar perlakuan terhadap kadar hemoglobin, persentase hematokrit, serta nilai indeks eritrosit (MCV, MCH, MCHC). Kesimpulan dari penelitian ini yaitu, pemberian Spirulina platensis selama 35 hari dalam ransum dapat menurunkan total eritrosit ayam broiler. Pemberian S. platensis sebagai prebiotik yang diberikan selama 7 atau 21 hari pemeliharaan memberikan hasil yang sama dengan pemberian AGPs (Antibiotics Growth Promoters) dilihat dari profil darah merah ayam broiler.

ABSTRACT:The study was conducted to evaluate the effect of duration feeding of Spirulina platensis as a prebiotic in ration on the red blood cells of broiler chickens. The material used in this study was 240 day old chick (DOC) with average of initial weight 42.015 ± 0.219 g. The experiment was designed based on Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treated treatments were T0 (Feed Basal + 0.04% Zinc Bacitracin), T1 (Basal diet + 1% Spirulina platensis for 7 days administration), T2 (Basal diet + 1% Spirulina platensis for 21 days of administration) and T3 (Feed Basal + 1% Spirulina platensis for 35 days of administration). Measured variables include total erythrocytes, hemoglobin, percentage of hematocrit, and erythrocyte index values (MCV, MCH, MCHC). Data were analyzed by variance test (F test) and if there was a significant difference then continued with Duncan's multiple range test. The results showed that there was significant differences (P <0.05) between treatments on total erythrocytes, and no significant differences (P> 0.05) between treatments on hemoglobin levels, hematocrit percentage, and erythrocyte index values (MCV, MCH, MCHC). It concluded that the feeding of Spirulina platensis for 35 days in ration can reduce total broiler erythrocytes and feeding S. platensis as a prebiotic given for 7 or 21 days of administration gives the same result as giving AGPs (Antibiotics Growth...
