Abstract

The aim of this research was to evaluate the effect of the addition of bio-herbal as a feed additive on feed consumption, hen day production, feed egg ratio and mortality of laying hens. The materials in this experiment used 200 laying hens of the Hyline strain age 28 to 36 weeks (reared for 60 days). The method used in this study was an in vivo experimental method using a Completely Randomized Design (CRD) with treatments consisting of P0 = drinking water without bio-herbals (control treatment), T1 = control treatment + bio-herbal yellow, P2 = control treatment + bio-herbal green, and T3 = control treatment + bio-herbal combination yellow and green (alternately every one week). Data were analyzed using Analysis of Variance (ANOVA) and if there was a significant effect, then tested with Duncan's Multiple Range Test. The observed variables were feed consumption, Hen Day Production (HDP), feed egg ratio and mortality. The results showed that the addition of bio-herbals had no significant effect (P > 0.05) on the feed consumption, hen day production, feed egg ratio and mortality. It can be concluded bio-herbal green gives the best results in improving egg quality. Due to the bioactive compounds of bio-herbal green, they consist of probiotic and phytobiotic.

Abstract

Bioherbal, a feed additive made from rhizome extract, exhibited promising capabilities in eradicating pathogenic bacteria residing within the digestive tracts of broiler chickens. The LpxC protein, a biosynthetic regulator of lipid A (a critical component of gram-negative bacterial cell walls), was the focus of this research. Our primary objective was to assess the bioactive potential of bioherbal as a prospective inhibitor of UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine (LpxC) by employing in silico methods. Computational analyses were employed to scrutinize the interactions between the LpxC protein and various ligands on Bioherbal. Molecular docking served as the initial screening process, evaluating 48 bioactive compounds based on energy affinity, conformation values, and interactions with protein residues. The three compounds exhibiting the lowest binding affinities were subjected to molecular dynamics simulations. Molecular docking analysis revealed that most of the screened compounds exhibited low binding affinity for LpxC. Elephantorrhizol, zedoraldehyde, glechomanolide, demethoxycurcumin, curcumin, hexahydrocurcumin, gweicurculactone, germacrone, and 1,2-dihydrocurcumin exhibited lower binding affinities (<-7 kcal/mol). Elephantorrhizol, curcumin, and hexahydrocurcumin were selected for further analysis via molecular dynamics due to their similarity to native ligands. Molecular dynamics simulations revealed stable interactions of LpxC. In summary, these findings suggested that Bioherbal possesses the potential to function as an LpxC inhibitor, thereby offering a promising avenue for preventing the proliferation of gram-negative bacteria within the digestive tracts of broiler chickens. This computational study paves the way for further experimental investigations in this domain.

Abstract

The overuse and continuous administration of antibiotics have led to the emergence of resistance, posing challenges in eradicating pathogenic bacteria in poultry digestive tracts. This concern has prompted breeders to seek alternatives, such as turmeric. Turmeric, known for its ability to combat disease-causing microorganisms in the digestive tract and improve livestock performance, is one such herb. This study aimed to assess the impact of fermented turmeric on the phytobiotic content and production performance of laying hens. In the initial phase, turmeric underwent anaerobic fermentation at room temperature for seven days, followed by analysis of curcuminoids and flavonoids. An in vivo study was subsequently conducted with 120 laying hens aged 50 weeks divided into five experimental groups: P0 (basal feed without fermented liquid turmeric) and T1--T4 (basal feed supplemented with fermented liquid turmeric). The results revealed a significant decrease in the curcumin and flavonoid contents after fermentation. Feed consumption increased significantly (P<0.05) but had no significant effect (P>0.05) on hen-day production, egg mass, FCR, or IOFC. numcially decreased FCR values. This study demonstrated that incorporating liquid turmeric into basal feed enhanced production performance while reducing FCR in laying hens. The effect of fermented liquid turmeric on feed consumption was sixty-four percent, and the feed conversion ratio was twenty-four percent. These findings suggest that fermented turmeric can effectively serve as a feed additive in poultry production systems, offering a natural alternative and potentially contributing to sustainable and healthy poultry farming practices

Abstract

The Sugar Factory of Tjoekir Jombang is one of the sugar factories located in Jombang, East Java under PT Perkebunan Nusantara X. Sugarcane waste, also known as bagasse causes pollution of the environment. Some microorganisms are able to degrade cellulose-containing bagasse, because of cellulolytic enzymes produced by cellulolytic bacteria. This study aims to obtain cellulolytic bacteria isolates, screen the highest cellulolytic activity, identify the highest cellulolytic activity isolates, and optimize conditions (pH and temperature) for the highest cellulase activity. Cellulolytic bacteria from bagasse were grown on a medium containing 1% CMC. Several additional minerals were other than those in the CMC medium. The cellulase activity was assayed semi-quantitatively with the addition of 0.1% Congo red and quantitatively using the 3,5-Dinitro Salicylic Acid (DNS) method. Bacterial isolates with high cellulolytic activity were identified based on the 16S rDNA sequence. This research obtained 20 bacterial isolates, where isolate A1T4 had the highest cellulolytic index of 1.18 mm. Measurement of cellulase activity using the DNS method showed that isolate A2T2 had the highest cellulase activity of 2.19 U/mL. Hemolysis assay showed that from 12 isolates, only two isolates have γ-hemolysis activity (isolates A1T6 and A3T3). Those isolates were optimized in a CMC broth medium with temperatures of 30°C and 37°C and pH 5 and pH 6 to produce the highest cellulase activity. Isolate A1T6 and A3T3 were grown optimally at 30oC and pH 6. Isolate A1T6 was identified as Citrobacter amalonaticus with a similarity of 99.80%, and isolate A3T3 was identified as Pseudomonas mendocina with a similarity of 98.83%.

Abstract

Buah Pare merupakan salah satu tumbuhan dengan banyak manfaat. Tujuan dari penelitian ini adalah untuk mengevaluasi penambahan tepung buah pare (Momordica charantia) pakan terhadap penampilan produksi ayam pedaging. Penelitian ini merupakan penelitian percobaan lapang pada 150 ekor ayam pedaging, dengan menggunakan 6 perlakuan (P0: Pakan basal + antibiotik Zink bacitracin; P1: Pakan basal + 0% tepung Buah Pare; P2: Pakan basal + 0.25% Tepung Buah Pare; P3: Pakan basal + 0.5% Tepung Buah Pare; P4: Pakan basal + 0.75% Tepung Buah Pare; P5: Pakan basal + 1% Tepung Buah Pare) dan 5 ulangan. Setiap unit percobaan terdiri dari 5 ekor ayam pedaging unsex strain Lohmann. Evaluasi pada penelitian dilakukan berdasarkan konsumsi pakan, Pertambahan Bobot Badan, Konversi Pakan, Income Over Feed Cost (IOFC), dan Indeks Produksi ayam pedaging. Penambahan tepung buah pare tidak menunjukkan pengaruh yang nyata terhadap konsumsi, konversi pakan, deplesi, indeks produksi, dan IOFC ayam pedaging, namun memberikan pengaruh yang nyata terhadap pertambahan bobot badan (P<0.05). Penambahan 0.5% tepung buah pare pada pakan menghasilkan konversi pakan dan IOFC terbaik.

Abstract

ABSTRACT. The purpose of this research was to investigate the use of candlenut powder (Aleurites mollucana (L.) Willd.) as feed additive on blood profile and meat cholesterol content of broilers. Materials used in this research were 200 day-old broiler chicks. Research method was in vivo on Completely Randomized Design with 5 treatments (P0 = basal diets only, P1 = basal diets + 0.25% candlenut powder, P2 = basal diets + 0.5% candlenut powder, P3 = basal diets + 0.75% candlenut powder, P4 = basal diets + 1% candlenut powder), each treatment was replicated 5 times. Variables measured were blood profile (erythrocyte, hemoglobin, mean corpuscular volume, and mean corpuscular hemoglobin) and meat cholesterol content. Data were analyzed by using Analysis of Variance. Data with significant different effects were further analyzed by using Duncans Multiple Range Test. The results showed that candlenut powder usage as feed additive had a highly significant effect on (P0.01) erythrocyte and hemoglobin levels. Candlenut powder also significantly affect (P0.05) mean corpuscular hemoglobin (MCH), but did not significantly affect (P0.05) mean corpuscular volume (MCV) levels. Broilers fed candlenut powder had lower (P0.01) meat cholesterol content compared to those fed basal diets only. It might be concluded that the use of candlenut powder as feed additive at the level of 1% is safely recommended to give better blood profile and reduce meat cholesterol content of broilers.Pengaruh penambahan tepung biji kemiri terhadap profil darah ayam pedaging dan kandungan kolesterol dagingABSTRAK.

Abstract

Pakan merupakan salah satu faktor yang mempengaruhi keberhasilan usaha peternakan. Faktor ini menyumbang persentase terbesar dibandingkan breeding dan managemen. Penyediaan pakan yang berkualitas, murah, mudah didapat, tidak bersaing dengan manusia tetapi memiliki kandungan nutrisi yang sesuai dengan kebutuhan sangat diperlukan untuk menunjang keberhasilan usaha peternakan. Salah satu upaya dalam peningkatan efisiensi pakan adalah dengan menggunakan natural growth promotor sebagai pengganti antibiotic growth promotor yang berasal dari ampas jamu. Ampas jamu dengan kandungan senyawa aktifnya mampu berperan sebagai antibakteri, antioksidan, dan antiinflamasi sehingga dapat menjaga kesehatan ayam. Ampas jamu yang difermentasi, ditambahkan probiotik, serta dibuat dalam ukuran nano memiliki daya serap lebih tinggi sehingga senyawa aktif di dalamnya mampu bekerja secara maksimal. Penelitian ini bertujuan untuk menganalisis pemberian nanopartikel ampas jamu dan probiotik sebagai feed additive ayam petelur terhadap produksi telur yang dihasilkan. Metode yang digunakan adalah kuantitatif dengan menguji ayam petelur secara in vivo menggunakan Rancangan Acak Lengkap (RAL). Level penambahan dalam pakan terdiri atas 4 perlakuan dan 4 ulangan dengan 5 ekor ayam untuk setiap ulangan. Perlakuan yang diberikan pada ayam petelur meliputi P0 (pakan basal), P1 (pakan basal + probiotik + nanopartikel ampas jamu 0,25%), P2 (pakan basal + probiotik + nanopartikel ampas jamu 0,50%), dan P3 (pakan basal + probiotik + nanopartikel ampas jamu 0,75%). Variabel yang diamati adalah produksi telur. Hasil penelitian menunjukkan bahwa penambahan nanopartikel ampas jamu dan probiotik pada pakan ayam petelur memberikan pengaruh sangat nyata (P<0,01) pada produksi telur. Terdapat peningkatan produksi telur yang dihasilkan pada perlakuan yang diberikan. Perlakuan penambahan nanopartikel ampas jamu dan probiotik terbaik terdapat pada P2. Kesimpulan dari penelitian ini adalah nanopartikel ampas jamu dan probiotik dapat dijadikan sebagai feed additive dalam menunjang performans produksi khususnya produksi telur pada ayam petelur.
