Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh perendaman larutan daun sirsak (Annona muricata) terhadap penurunan kadar lemak total dan kolesterol pada beef abomasum serta menentukan konsentrasi optimalnya. Penelitian menggunakan rancangan acak lengkap (RAL) dengan lima perlakuan dan tiga ulangan, yaitu P0 (kontrol, aquades), P1 (larutan daun sirsak 5%), P2 (10%), P3 (15%), dan P4 (20%). Setiap perlakuan menggunakan 100 gram beef abomasum yang direndam selama 60 menit. Hasil penelitian menunjukkan bahwa perendaman dengan larutan daun sirsak berpengaruh nyata terhadap kadar lemak total dan kolesterol. Nilai rata-rata kadar lemak total tertinggi diperoleh pada kontrol (P0) sebesar 7,44 ± 0,039 dan terendah pada perlakuan P4 sebesar 6,15 ± 0,042. Demikian pula kadar kolesterol tertinggi terdapat pada P0 sebesar 179,40 ± 2,19 dan terendah pada P4 sebesar 122,74 ± 2,69. Konsentrasi 20% (P4) merupakan perlakuan paling efektif dalam menurunkan kadar lemak total dan kolesterol pada beef abomasum.  ABSTRACTThis study aims to determine the effect of soaking beef abomasum in soursop leaf (Annona muricata) solution on the reduction of total fat and cholesterol levels and to determine the optimal concentration. The study used a completely randomized design (CRD) with five treatments and three replicates, namely P0 (control, distilled water), P1 (5% soursop leaf solution), P2 (10%), P3 (15%), and P4 (20%). Each treatment used 100 grams of beef abomasum soaked for 60 minutes. The results showed that soaking in soursop leaf solution had a significant effect on total fat and cholesterol levels. The highest average total fat level was obtained in the control (P0) at 7.44 ± 0.039 and the lowest in treatment P4 at 6.15 ±0.042. Similarly, the highest cholesterol level was found in P0 at 179.40 ± 2.19 and the lowest in P4 at 122.74 ± 2.69. A concentration of 20% (P4) was the most effective treatment in reducing total fat and cholesterol levels in beef abomasum.

Abstract

ABSTRACTThe increasing demand for chicken meat requires strategic efforts to improve the carcass quality of broiler chickens. One approach to achieve this objective is through effective feed management. This study aimed to evaluate the effects of feeding two different commercial concentrates on carcass quality (carcass percentage and abdominal fat) and economic efficiency (feed cost per gain) of broiler chickens. The experiment was conducted using a Completely Randomized Design (CRD) and analyzed by analysis of variance (ANOVA), consisting of three dietary treatments with four replications, each replication containing three broiler chickens. The treatments included P1: broilers fed 100% commercial concentrate A; P2: broilers fed 100% commercial concentrate B; and P3: broilers fed a mixture of 50% commercial concentrate A and 50% commercial concentrate B. The optimal results were observed in P1, with a carcass percentage of 73.92%, abdominal fat percentage of 1.05%, and feed cost per weight gain of IDR 13,790. In contrast, the lowest results were recorded in P3 (50% commercial concentrate A and 50% commercial concentrate B), with a carcass percentage of 70.87%, abdominal fat percentage of 1.16%, and feed cost per weight gain of IDR 13,873. It can be concluded that the use of different commercial concentrates significantly affected carcass quality, particularly carcass percentage, but had no significant effect on abdominal fat percentage or feed cost per gain in broiler chickens.Keywords: abdominal fat, broiler chicken, feed cost per gain, carcass, commercial feed

Abstract

This study aimed to evaluate the effect of different doses of MA-11 on the physical quality, pH, and dry weight of a fermented mixture of banana pseudostem and Indigofera forage with molasses addition. Fermentation was applied as a method to improve the utilization of local feed resources with low physical quality. The experiment was conducted using a Completely Randomized Design with three treatments and four replications. The treatments consisted of P0: banana pseudostem + Indigofera forage + molasses (control), P1: banana pseudostem + Indigofera forage + molasses + 1 cc MA-11, and P2: banana pseudostem + Indigofera forage + molasses + 2 cc MA-11. Fermentation was carried out for 12 days. The observed variables included physical quality (color, aroma, and texture), pH value, and dry weight. Data were analyzed using analysis of variance followed by Duncan’s Multiple Range Test. The results showed that MA-11 supplementation significantly improved the physical quality of the fermented mixture, as indicated by higher scores for color, aroma, and texture compared to the control. In addition, MA-11 significantly reduced the pH value of the fermented product. However, the application of MA-11 had no significant effect on dry weight. It can be concluded that the fermentation of banana pseudostem and Indigofera forage using MA-11 effectively improved physical quality and fermentation characteristics, although it did not affect dry weight.

Abstract

Commercial concentrates have different nutrient formulations, which may potentially affect body tissue growth and the development of internal organs in broiler chickens, ultimately influencing the percentage of carcass parts and internal organs. This study aimed to determine the effect of feeding two different types of commercial concentrates on the percentage of carcass parts and internal organs of broiler chickens. The experimental design used was a Completely Randomized Design with a one-way pattern consisting of three treatments and four replications. The treatments were P1: 100% commercial concentrate A; P2: 100% commercial concentrate B; and P3: 50% commercial concentrate A + 50% commercial concentrate B. The observed variables included the percentages of thigh, wing, and breast parts, as well as the percentages of heart, gizzard, and liver. The obtained data were statistically analyzed using analysis of variance (ANOVA), and when significant differences were detected, Duncan’s Multiple Range Test was applied. The results showed that the percentages of breast and thigh parts among P1, P2, and P3 did not differ significantly; however, the percentage of wing parts in P1 was significantly lower than in P2 and P3. The percentages of heart and liver in P1, P2, and P3 did not show significant differences, whereas the gizzard percentage in P1 was significantly different compared to P3. It can be concluded that feeding two different types of commercial concentrates significantly affected the percentages of wing and gizzard parts but did not significantly affect the percentages of breast, thigh, heart, and liver.

Abstract

Mycotoxin contamination in poultry feed is a major concern in broiler production because it can reduce feed quality, impair nutrient absorption, and negatively affect growth performance. This study aimed to evaluate the effect of anti-mycotoxin (toxin binder) supplementation in the diet on broiler chicken performance, including feed intake, average daily gain (ADG), and feed conversion ratio (FCR). The study lasted for 28 days and involved day-old broiler chicks set up in a completely randomized design (CRD) with three treatments and three replications. The treatments were P0 (a control diet lacking a toxin binder), P1 (a diet with a toxin binder added), and P2 (a diet with the highest amount of toxin binder). Data analysis was carried out using analysis of variance (ANOVA), followed by the least significant difference (LSD) test at a 5% significance level. Findings indicated that adding a toxin binder had a significant impact (P<0.05) on the feed intake, average daily gain (ADG), and feed conversion ratio (FCR) in broiler chickens. The P2 treatment achieved the best results, exhibiting the lowest FCR value, whereas the P1 treatment did not display any significant difference when compared to the control group.
