Abstract

This study was conducted to investigate the effect of different level of energy and crude fiber in diets containing sawdust on carcass quality of broilers. A total of 120 broilers were used for the research. The experiment utilized a completely randomized design in 2 x 3 factorial arrangement of treatments consisting of two dietary concentrations of energy and three dietary concentrations of crude fiber. Each treatment consisted of 4 replications (5 birds each) was reared during 35 days. The birds were housed in battery cages with ad libitum access to feed and water. During the experiment, feed intake, carcass yield, abdominal fat, blood LDL-cholesterol and HDL-cholesterol were measured. Data were subjected to the analysis of variance test followed by least significant difference test (LSD). Results showed that the diet with 3,100 Kcal/kg ME and 11% crude fiber significantly decreased feed intake, abdominal fat percentage, and blood LDL-cholesterol, but did not affect final body weight and the value of blood HDL-cholesterol and had the good value of carcass percentage. The diets containing sawdust with higher level of energy content decreased feed intake and the higher level of crude fiber decreased final body weight, carcass percentage and abdominal fat. Optimum broiler performance and carcass quality was obtained by diet formulated to contain 3100 Kcal/kg ME and 11% crude fiber.

Abstract

The study was conducted to evaluate the effect of level of banana (Musa paradisiaca) leaves fermented with Trichoderma viride at different days on the carcass yield of broiler chickens. A hundred and eighty 3-weeks-old broiler chicks were used in this present experiment based on factorial design (3×4). The birds were randomly allocated into three experimental diets containing of 5, 10 and 15% of banana leaves fermented within 0, 5, 10 and 15 days. Each treatment was divided into three replicates of five chicks in each. The experiment was terminated after 4 weeks or when the birds were 7-weeks-old. Feed intake, body weight gain, feed efficiency and carcass yield were measured during the study. The data were subjected to the analysis of variance test followed by least significant difference (LSD) test. Results showed that daily feed intake was significantly affected (P˂0.01) by the dietary treatments, in which feed intake was highest in broilers fed diet containing 10% banana leaves fermented for 10 days. The daily weight gain, feed efficiency and carcass yield were significantly affected (P˂0.01) by the treatments, in which the highest values of daily weight gain, feed efficiency, and carcass yield were observed in birds fed diet containing 10% banana leaves fermented for 10 days. It can be concluded that diet containing 10% banana leaves fermented for 10 days can be included in broiler ration without detrimental effects on the performance and carcass yield.

Abstract

ABSTRAKPenelitian ini dilakukan untuk menguji pengaruh pemberian kombinasi herbal dengan mineral zink dalam ransum broiler yang diinfeksi Escherichia coli (E. coli). Dua ratus ekor d.o.c (day old chick) dibagi secara acak ke dalam lima perlakuan, masing-masing perlakuan diulang empat kali sehingga terdapat 20 unit percobaan, setiap unit percobaan terdiri dari 10 ekor d.o.c. Anak ayam percobaan dipelihara selama 35 hari. Ransum perlakuan terdiri dari R1 = Pakan basal/ ayamsehat (kontrolnegatif); R2 = Pakan basal/ ayamdiinfeksiE.coli (kontrolpositif); R3= Pakan basal + serbukkunyit 1.5% + ZnO 180 ppm/ ayamdiinfeksiE.coli; R4 = Pakan basal + serbukbawangputih 2.5% + ZnO 180 ppm/ ayamdiinfeksiE.coli; R5 = Pakan basal + antibiotik/ ayamdiinfeksiE.coli.Penelitian menggunakan rancangan acak lengkap. Peubah yang diamati konsumsi ransum, pertambahan bobot badan, dan konversi ransum. Hasil dari penelitian ini menunjukkan bahwa pemberian kombinasi kunyit 1.5% dengan ZnO 180 ppm dan kombinasi bawang putih 2.5% dengan zink 180 ppm dalam ransum mampu memperlihatkan performa yang lebih baik.Kata Kunci:Daun ubi jalar, Pertambahan berat badan, Konsumsi ransum, Konversi ransum, Ayambroiler.ABSTRACTTHE EFFECT OF SUPPLEMENTA-TION SWEET POTATO LEAVES MEAL (Ipomea batatas) ON BROILER PERFORMANCE.This experiment was conducted to study the combination of herbal with zink in poultry diet on the performance of Escherichia coli – challenged broiler. Two hundred d.o.c unsexed were devided into five treatments and four replications, with ten chicks in each replicates. The treatments were R1 (basal diet as a negative control/ healhty chickens), R2 (basal diet as a positive control/ Escherichia coli challenged), R3 (basal diet +1.5% turmeric powder + ZnO 180 ppm/ Escherichia coli challenged), R4 (basal diet + 2.5% garlic powder + ZnO 180 ppm/ Escherichia coli challenged), and R5 (basal diet + antibiotic/ Escherichia coli challenged). Data were collected during 35 days, diet and water were offered ad libitum. The results of this research indicated that chickens fed basal diet + 1.5% turmeric powder + ZnO 180 ppm/ challenged Escherichia coli and chickens fed basal diet + 2.5% garlic powder +ZnO 180 ppm/ challenged Escherichia coli showed performances better than control .Keywords: Sweet potato leaves, Body weight, Consumtion ration, Convertion ration, Broiler
