Judul: Supplementation of Chaya Leaves  (Cnidoscolus aconitifolius) infusion on the Productivity and Egg Quality of Quail  17-20 Weeks Old
Abstrak: Pepaya jepang (Cnidoscolus aconitifolius) merupakan tanaman yang memiliki daun mirip daun pepaya namun dengan warna daun hijau tua, tanaman ini mengandung senyawa fitokimia yang dapat berfungsi sebagai antibakteri, antioksidan, dan antiimflamsi. Penelitian ini bertujuan untuk untuk mengevaluasi suplementasi infusa daun pepaya jepang terhadap produtivitas dan kualitas telur puyuh jepang petelur (Coturnix coturnix japonica) umur 17-20 minggu. Infusa daun pepaya jepang diberikan melalui air minum dan diharapkan dapat meningkatkan produksi dan kualitas telur puyuh. Peubah yang diamati terdiri atas produktivitas puyuh petelur (konsumsi air minum, konsumsi pakan, bobot telur, Quail Day Production, massa telur, konversi pakan, mortalitas), kualitas telur (bobot dan persentase kuning telur, putih telur, dan kerabang telur, indeks telur, indeks kuning telur, indeks putih telur, tebal kerabang, warna kuning telur, dan haugh unit), organ dalam dan imunitas, organ reproduksi, serta kandungan Malondialdehid (MDA) dalam kuning telur. Penelitian ini dianalisis menggunakan Uji T dengan 2 perlakuan dan 4 ulangan: P0 = kontrol dan P1 = pemberian infusa daun pepaya jepang dengan konsentrasi 10%. Hasil menunjukan suplementasi infusa daun pepaya jepang berpengaruh signifikan (p<0,05) terhadap peningkatan produktivitas yaitu quail day production, massa telur, konversi pakan dan tidak berpengaruh signifikan (p>0,05) terhadap konsumsi air minum, konsumsi pakan, bobot telur, dan mortalitas. Suplementasi infusa daun pepaya jepang berpengaruh signifikan (p<0,05) terhadap peningkatan indeks putih, warna kuning telur, dan tidak berpengaruh signifikan (p>0,05) terhadap bobot dan persentase kuning telur, putih telur, dan kerabang telur, indek telur dan indeks kuning telur, tebal kerabang telur, serta haugh unit. Selain itu, suplementasi infusa daun pepaya jepang tidak berpengaruh signifikan (p>0,05) terhadap bobot dan persentase organ dalam (hati, jantung, proventrikulus, dan ventrikulus) dan organ imunitas (limpa dan kelenjar timus). Suplementasi infusa daun pepaya jepang berpengaruh signifikan (p<0,05) terhadap persentase ifundibulum dan panjang isthmus namun tidak berpengaruh signifikan (p>0,05) terhadap bobot dan panjang infundibulum; bobot, persentase, dan panjang magnum; bobot dan persentase isthmus; bobot, persentase, dan panjang uterus; serta bobot, persentase, dan panjang vagina. Suplementasi infusa daun pepaya jepang berpengaruh signifikan (p<0,05) terhadap penurunan kandungan MDA kuning telur. Oleh karena itu, penggunaan infusa daun pepaya jepang 10% dalam air minum dengan pemberian dua kali seminggu dapat meningkatkan produktivitas dan kualitas telur puyuh jepang petelur umur 17-20 minggu sehingga dapat meningkatkan pendapatan selama pemeliharaan., Chaya (Cnidoscolus aconitifolius) is a plant that has leaves similar to papaya leaves but with dark green leaf color. This plant contains phytochemical compounds that can function as antibacterial, antioxidant and anti-inflammatory. This study aimed to evaluate supplementation of chaya leaf infusion on the productivity and egg quality of quail (Coturnix coturnix japonica) 17-20 weeks old. Chaya leaf infusion was given through drinking water and is expected to increase the production and quality of quail eggs. The variables observed consisted of productivity (water intake, feed intake, egg weight, quail day production, egg mass, feed conversion ratio, mortality), egg quality (yolk, albumen, eggshell weight and percentage, egg index, yolk index, albumen index, shell thickness, yolk color, and haugh units), internal and immunity organs, reproductive organs, and Malondialdehid (MDA) content in yolk. This study was analyzed using the T test with 2 treatments and 4 replications: P0 = control and

Abstrak: Tectone leaf is plant perennial who had the chance very large for use as fodder. The availability and its abundant known was selected as one alternative plant a source of materials local feed. Generally of tecton trees used to be taken wood as major commodity logistics. Hence in the study is done the utilization of waste in the form of tecton leaf meal in diet laying quail. Active ingredients that was found in the leaves of flavonoid tecton namely. A compound phytochemistry is able to inhibit the growth of pathogenic bacteria in the digestive tract so that the absorption of nutrient could be optimal and no mortality on experiment. The supplementation tecton leaf can improve balance the necessary of feed nutrient quails and increase productivity of egg quail. This study aimed to analyze supplementation meal and extract tectone leaf in quails diet on antimicrobial activities such as bacteria pathogen E.coli and S.typhimurium on digestive tract so it could improve the quail performance and egg quality. This research used the laying Japanese quail (Coturnix coturnix japonica) aged 4-12 weeks as many as 180 bird given the supplementation tecton meal in diet and extract tecton leaf in drinking water. A method of research is experiment with design random complete (CRD) consist of six treatments and three replications. Treatments consist of : R0 = commercial rations, R1 = commercial rations + Vitachick, R2 = commercial rations + 6% meal tecton leaf, R3 = commercial rations +6% extract tecton leaf, R4= commercial rations+ 9% meal tecton leaf, R5 = commercial rations + 9% esxtract tecton leaf in drinking water. Parameters observed were feed consumption, water consumption, egg production, egg weight, egg mass, feed conversion, yolk weight and albumin weight, egg yolk colour score, eggshell weight, eggshell thickness, haugh unit, total of colonies bacteria, and analysis of Income Overfeed Cost. The analysis showed that meal tecton leaf proximate containing crude protein 11.01%, crude fat 3.80%, crude fiber 22.01%, and ash 8.11%. Active compound of flavonoid that was found in extract and meal tecton leaf is 0.241% and 0.643%. The result showed that the addition of meal and extract tecton leaf didn’t affect significantly (P>0.05 ) of feed consumption, water consumption, egg production and feed conversion. There was no mortality during this experiment. The addition of meal tecton leaf 6% and 9% could be increase a score of yolk colour to 8 with a yellow color. Supplementation extract tectone leaf 9% to reduce the total bacteria colonies E.coli and S. typhimurium. Flavonoids were able to inhibit the growth of pathogenic bacteria with the concentration of the medium. The conclusion of this research was supplementation 6% tecton leaf was able to increase the egg yolk color score while was able to reduce the total population of the colonies of pathogenic bacteria of the digestive tract quail can be given the addition of 9% extract tecton leaf. The content of flavonoid that serves as the meal contained in the antibacterial meal and extract tecton leaf is 0.643% and 0.24%.
