“…The result showed that percentage of abdominal fat significantly decreased although dietary energy level increased, and that was due to high crude fiber level. This result was similar to Shahin and Abdelazim (2006), who reported that abdominal fat, carcass fat and total body fat yields greatly decreased by feeding birds with high fiber diets and produces less abdominal fat depots. At the other side, Mourao et al (2008) reported that birds fed diets containing insoluble fiber produced lighter carcasses with lower levels of abdominal fat compared with control.…”

ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh level energi dan serat kasar dalam ransum yang mengandung serbuk gergaji terhadap kualitas karkas ayam pedaging. Sebanyak 120 ekor ayam pedaging digunakan dalam penelitian ini. Percobaan menggunakan rancangan acak lengkap pola factorial 2 x 3 dengan 4 ulangan. Perlakuan terdiri dari 2 level energi dan 3 level serat kasar. Ayam dipelihara selama 35 hari dalam kandang baterei, dan pemberian pakan dan air minum dilakukan ad libitum. Variabel yang diamati adalah konsumsi pakan, produksi karkas, lemak abdominal, LDL dan HDL-kolesterol darah. Data dianalisis dengan analisis keragaman dan dilanjutkan dengan uji beda nyata terkecil. Hasil penelitian menunjukkan bahwa perlakuan 3100 Kkal/kg ME dan 11% serat kasar nyata menurunkan konsumsi pakan, persentase lemak abdominal dan LDL-kolesterol darah, tetapi tidak mempengaruhi berat badan akhir dan nilai HDL-kolesterol darah serta tetap mempertahankan nilai persentase karkas yang baik. Dapat disimpulkan bahwa kombinasi perlakuan 3100 Kkal/kg ME dan 11% serat kasar pada ransum yang mengandung serbuk gergaji dapat digunakan dalam pakan ayam pedaging.Kata Kunci: ayam pedaging, energi, kualitas karkas, serat kasar, serbuk gergaji ABSTRACTThis 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.

The objectives of this research was to study the effect and level of using purslane flour (Portulaca oleracea L) which was substituted in broiler feed to performance, had been done in chicken coop owned by National Animal Husbandry Training Centre Kupang. The experimental used was Completely Randomized Block Design (CRBD) with 4 (four) treatments, 5 (five) blocks and 5 (five) replications, each replication consist of 5 (five) broilers, so the total of the broiler were 100 heads. The treatments were Kr0 = commercial feed without purslane flour, Kr5= commercial feed contained 5% purslane flour, Kr10= commercial feed contained 10% purslane flour and Kr15= commercial feed contained 15% purslane flour. Parameters measured were feed intake (dry matter, crude protein, and crude fiber), weight gain, feed conversion and weight of abdominal fat. Data were analyzed using Analysis of Variance (ANOVA). The results of the study showed that the use of purslane flour in broiler feed had a very significant effect (P<0.01) to feed intake, weight gain and feed conversion but had no significant effect (P>0.05) to weight of abdominal fat. The use of purslane flour in broiler feed up to 15% does not improve performance of broiler.Key words: broiler, purslane flour, performance. ABSTRAKPenelitian ini dengan tujuan mengetahui pengaruh dan level penggunaan tepung krokot (Portulaca oleracea L) yang disubtitusi dalam ransum ayam broiler terhadap performans, telah dilakukan di kandang ayam milik Balai Besar Pelatihan Peternakan Kupang. Rancangan yang digunakan adalah Rancangan Acak Lengkap Berblok (RAL B) yang terdiri dari 4 perlakuan, 5 blok dan 5 ulangan dengan masing-masing ulangan sebanyak 5 ekor sehingga total ayam adalah 100 ekor. Perlakuan tersebut yaitu Kr0= Ransum komersial tanpa tepung krokot, Kr5= Ransum komersial yang mengandung 5% tepung krokot, Kr10= Ransum komersial yang mengandung 10% tepung krokot dan Kr15= Ransum komersial yang mengandung 15% tepung krokot. Parameter yang diukur adalah konsumsi (bahan kering, protein kasar dan serat kasar), pertambahan berat badan, konversi ransum dan berat lemak abdomen. Data yang diperoleh dianalisis menggunakan Analysis of Variance (ANOVA). Hasil penelitian menunjukkan bahwa penggunaan tepung krokot dalam ransum berpengaruh sangat nyata (P<0,01) terhadap konsumsi, pertambahan bobot badan dan konversi ransum tetapi tidak berpengaruh nyata (P>0,05) terhadap berat lemak abdomen. Penggunaan krokot dalam ransum hingga level 15% tidak memperbaiki performans ayam broiler.

Excessive fat in modern broiler strains is one of the major problems faced by the broiler industry. This experiment was conducted to study the effect of feed restriction at early age on broiler chicken performance, meat quality, abdominal fat content, and serum lipid profile. Two hundred, Cobb500 day-old broiler chicks were randomly assigned into five treatments; T1: ad-libitum feeding (control), T2 and T3: 75 and 50% of ad-libitum feeding from day 8-14, respectively, T4 and T5: 75 and 50% of ad-libitum feeding from day 15-21, respectively. All birds were fed with ad-libitum before and after the completion of the respective restriction periods. Total feed intake was significantly lower (p<0.05) in T3 and T5 compared to the birds in the control group. However, no differences (p>0.05) were observed in weight gain, feed conversion ratio, and dressing percentage among the treatments. Abdominal fat and muscle crude fat contents in birds fed with restricted diets from day 8-14 were significantly lower (p<0.05) compared to the control. There was no influence (p>0.05) of treatments on organ weights, muscle protein contents, and serum lipid profile. In conclusion, 50% feed restriction during day 8-14 is a better solution to reduce the fat deposition without interfering on growth performances of broiler chicken with lower cost.
