Abstract

CARCASS PERFORMANCE OF BROILER FED RATION CONTAINING COFFEE (Coffea sp) HUSK WASTE PRODUCT TREATED BY SIMPLE PROCESSING AND SUBSTITUTING PARTS OF CORN WITH DIFFERENT LEVELS. Broilers had rapid growth rate and need high nutrient protein and energy balance in the diet. This study was conducted to evaluate the use of coffee husk waste product treated by simple processing substituted with part of corn in ration on carcass percentage of broiler. Study was applied at Faculty of Animal Science, Sam Ratulangi University during 35 days. Total of 144 day old chick unsexed broilers, strain of CP 707, involving 36 experimental units of battery pens were used in this study. Each unit of pen was filled 4 birds under completely randomized design on factorial patter of 3x4. Factor A was focused on three processing treatments including coffee husk heated under sun light (A1), coffee husk immersed in the water (A2), and coffee husk boiled under water (A3). Factor B was focused on four treatments of substitution levels including ration containing corn without coffee husk substitution (B0), ration containing corn substituted with 25% coffee husk (B1), ration containing corn substituted with 50% coffee husk (B2), ration containing corn substituted with 75% coffee husk (B3). Variables observed were including percentages of thigh, wing, breast and back part. Analysis of variance showed that interaction of processing treatments did not affect significantly on the percentages of thigh, wing, breast and back part. This study indicated that simple processing of coffee husk were not affected the carcass percentages of broiler. The substitution levels significantly affected carcass percentage of broiler. Percentages of thigh, wing, breast and back part were 28.92%-30.98%, 10.38%-12.68%, 35.10%-38.55% and 19,68%-22,71%, respectively. This study showed that utilization of coffee husk waste product by above simple processing could substitute part of corn in ration of 25% producing high carcass percentage of broiler.Keywords: Coffee husk by product, broiler part of carcass percentage

Abstract

Penelitian bertujuan untuk mengetahui penerapan biosekuriti pada peternakan ayam ras petelur Mantiri’s Farm di Kelurahan Pangolombian. Penelitian ini adalah observasi lapangan, menggunakan pendekatan deskriptif kualitatif dengan metode survey yang fokus pada metode sampel, pengamatan serta wawancara. Menggunakan skala Likert dengan empat alternatif dan dilanjutkan dengan uji Friedman. Komponen biosekuriti yang dinilai meliputi aspek lingkungan yang terdiri dari  biosekuriti sumber ayam, hewan pengganggu, tamu dan pekerja, dan limbah peternakan. Berdasarkan hasil penelitian pengetahuan dan fasilitas menunjukkan bahwa penerapan biosekuriti sumber ayam dengan rata-rata 3,4 dan nilai Sig. 1>0,05, hewan pengganggu 3,3 dan nilai Sig. 0,094>0,05, tamu dan pekerja 3,83 dan Sig. 1>0,05,  limbah ternak 3,5 dan Sig. 0,093>0,05 maka Mantiri’s Farm mampu menunjang pelaksanaan biosekuriti. Berdasarkan hasil dan pembahasan dapat disimpulkan bahwa penerapan biosekuriti pada Mantiri’s Farm di Kelurahan Pangolombian dilihat dari aspek lingkungan sudah mampu menunjang penerapan biosekuriti. Kata Kunci:  Biosekuriti, ayam petelur, lingkungan peternakan
