PENGARUH PEMBERIAN EKSTRAK DAUN JAMBU METE (Anacardium occidentale, L) MUDA TERHADAP KADAR HEMOGLOBIN DAN JUMLAH SEL DARAH MERAH (ERYTHROCYTE) PADA AYAM BROILER ABSTRAK Oleh: Ade Susanti 06308141003 Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak daun Jambu Mete (Anacardium occidentale, L) muda terhadap kadar hemoglobin dan sel darah merah (Erythrocyte) pada ayam broiler. Penelitian ini menggunakan rancangan acak lengkap (RAL) dan ulangan sebanyak 5 perlakuan. Sampel penelitian ini adalah ayam broiler umur 1 hari (DOC) sebanyak 30 ekor, yang dibagi dalam 5 perlakuan dan 1 kontrol. Variable bebas dari penelitian ini adalah variasi konsentrasi ekstrak daun Jambu Mete (Anacardium occidentale, L.) muda. Variabel tergayut dari penelitian ini adalah kadar hemoglobin darah dan jumlah sel darah merah (Erythrocyte) pada ayam broiler. Analisis kadar hemoglobin dilakukan dalam metode Sahli dan penghitungan jumlah sel darah merah dilakukan dengan alat Haemacytometer. Data yang diperoleh dianalisis menggunakan analisis Varian (ANOVA) jika ada perbedaan nyata dilanjutkan dengan uji DMRT (Duncan Multiple Range Test). Hasil penelitian menunjukkan bahwa tidak ada pengaruh nyata (p>0.05) pemberian ekstrak daun Jambu Mete muda terhadap kadar hemoglobin (Hb) pada ayam broiler dan jumlah sel darah merah (erythrocyte). Pemberian ekstrak daun Jambu Mete muda pada ayam broiler, mengalami kenaikan jumlah satuan sel darah merah (erythrocyte) seiring dengan kenaikan dari dosis. Kata kunci: daun Jambu Mete, ayam broiler, kadar hemoglobin, erythrocyte. INFLUENCES OF GIVING YOUNG CASHEW LEAF EXTRACTS (Anacardium occidentale, L) TOWARDS HEMOGLOBIN LEVELS AND THE NUMBER OF RED BLOOD CELLS (ERYTHROCYTE) IN BROILER CHICKENS ABSTRACT By: Ade Susanti 06308141003 This research aims at determining influences of giving young cashew leaf extracts (Anacardium occidentale, L) towards hemoglobin levels and red blood cells (erythrocyte) in broiler chickens. This research used Completely Randomized Design (CRD) and repetition as much as 5 treatments. The research sample was 30 one-year-old broiler chickens (DOC) divided into 5 treatments and 1 control. The independent variable of the research was variations on extract concentrations of cashew leaf (Anacardium occidentale, L.). The dependent variable of the research was hemoglobin levels of blood and the number of red blood cells (erythrocyte) in broiler chickens. Analysis of hemoglobin levels was done in the Sahli method and the red blood cell count was done with a Hemacytometer. Data gained were analyzed using Variant analysis (ANOVA) and if there was any real difference, it would be continued with the DMRT test (Duncan Multiple Range Test). Research results show that there is no real influence (p>0.05> of giving young cashew leaf extracts on hemoglobin levels (Hb) in broiler chickens and the number of red blood cells (erythrocyte). Giving young cashew leaf extracts in broiler chickens affects in raising the number of red blood cell units (erythrocyte) in line with the raising of doses. Keywords : cashew leaves, broiler chickens, hemoglobin levels, erythrocyte.
