Abstract

The objective of the study was to determine the effects of feeding Lactobacillus species (Lactobacillus sp.) and inulin derived from dahlia tuber powder on antioxidant activity, calcium mass, and protein mass of crossbred kampong chicken meat. A total of  168 birds of 21 days old crossbred kampong chickens were randomly allocated into 6 treatments with four replications per treatment. The present experiment was assigned in  a completely randomized design with 2 x 3 factorial scheme. The first factor was levels of dahlia tuber powder, namely 0.8% (A1) and 1.2% (A2), and the second factor was levels of Lactobacillus sp., namely none (B0), 1.2 mL (108 cfu/mL/B1) and 2.4 mL (108 cfu/mL/B2). The parameters measured were antioxidant activity, meat calcium and protein mass. Data were subjected to analysis of variance and followed by Duncan multiple range test (P

Abstract

Ringkasan Ayam Kedu sebagai plasma nutfah Jawa Tengah dianggap mempunyai potensi genetik yang lebih baik jika dibandingkan dengan ayam lokal pada umumnya Namun, kajian ilmiah yang ada sangat terbatas. Kenyataan menunjukkan bahwa angka mortalitasnya cukup tinggi dan kemampuan produksinya masih rendah, baik pada pemeliharaan in situ maupun ex situ. Penelitian tentang perkembangan fungsi fisiologis alat pencernaan, dilihat dari aktivitas enzim protease pada usus halus dan pankreas, dan perubahan bobot dan panjang usus halus, dilakukan pada ayam Kedu berasal dari pemeliharaan in situ. Perkembangan alat pencernaan merupakan indikator dari kemampuan memanfaatkan nutrisi untuk hidup pokok, produksi, dan kesehatan. Pengamatan terhadap perkembangan alat pencernaan mengikuti pola perbedaan umur (time course), mulai umur 2 minggu (interval waktu 2 minggu) dan berakhir pada umur 10 minggu. Jumlah ayam yang diamati sebanyak 100 ekor dengan dekapitasi sebanyak 20 ekor setiap 2 minggu (dibagi menjadi 4 kelompok sebagai unit percobaan atau ulangan). Waktu/umur pengamatan merupakan perlakuan. Aktivitas enzim protease total pada usus halus dan pankreas, bobot dan panjang usus halus merupakan parameter penelitian. Aktivitas enzim protease total ditentukan menurut metode Colowick dan Kaplan (1985). Data diolah statistik menurut analisis ragam dan dilanjutkan dengan uji Duncan untuk membandingkan antarwaktu/umur pengamatan. Data aktivitas enzim diuji dengan perhitungan regresi (Sudjana, 1983), untuk menentukan saat perkembangan alat pencernaan paling maksimal. Hasil penelitian menunjukkan bahwa aktivitas protease total, sebagai indikator dari perkembangan fisiologis saluran pencernaan, meningkat pesat (P<0,05) baik pada usus halus maupun pankreas seiring dengan bertambahnya umur. Bobot dan panjang usus halus tampak semakin meningkat (P<0,05) dengan bertambahnya umur sampai 10 minggu, kecuali panjang usus antara umur 2 dan 4 minggu tidak berbeda. Peningkatan aktivitas protease total berkisar antara 3 - 3,5 kali dan 4 - 4,5 kali lebih tinggi masing-masing untuk usus halus dan pankreas pada umur 8 atau 10 minggu dibandingkan dengan umur awal (2 minggu). Secara umum, percepatan perkembangan fisiologis usus halus meningkat, tetapi pertambahan panjang agak tersendat pada umur awal.

Abstract

Indonesian Indigenous poultry originated from the central part of Java Island, called Kedu chick-en, given diet added with inulin of dahlia tuber extract (IDTE) to evaluate body resistance and protein deposition. The experimental animals were 150 birds of 14-day-old Kedu chicken (initial body weight was 148 ± 16.4 g) until 12 weeks old. Dietary treatments were T1: farmer’s diet with protein concen-trate; T2: T1 + 1.2% inulin of IDTE, and T3: modified diet with common protein sources + 1.2% IDTE. A completely randomized design was assigned with 3 treatments (5 replications with 10 birds each). Parameters observed were rate of passage, protein and fiber digestibilites, Nitrogen (N) and Cal-cium (Ca) retentions, body resistance (plasma concentration of corticosterone/CTC, level of immuno-globulin A/IgA, and heterophyl-lymphocyte/H/L ratio), protein metabolism (fecal Nτ–methylhistidine/Nτ–MH and muscle protein mass), feeds consumption, feed conversion ratio (FCR), and body weight gain (BWG). Analysis of variance and Duncan’s test were applied to analyze data. Rate of passage, N and Ca retentions, BWG, IgA level, and muscle protein mass increased; in contrast, FCR, fecal Nτ–MH, and plasma CTC decreased due to the feeding effect of the T3 diet. All parameters, except IgA level, between treatment T1 and T2 indicated similar values. It can be concluded that a modified diet added with IDTE (T3) can modulate the increase in N retention and immune status, with the decrease in muscle protein degradation indicated by low fecal Nτ–MH excretion, and finally, brings about a bet-ter growth rate, with higher muscle protein deposition.

Abstract

This study aimed to evaluate the effects of encapsulated dahlia tuber extract and Bacillus subtilis (EdteBs) on intestinal morphology, protein digestibility, and broiler performance. A total of 200 eight-day-old Ross 308 broilers (initial body weight: 194.60 ± 3.46 g) were divided into four dietary treatments with five replications. The treatments were: T0 – basal diet (control) without EdteBs supplementation; T1 – T0 + 0.1% EdteBs; T2 – T0 + 0.2% EdteBs; and T3 – T0 + 0.3% EdteBs. Variables measured included potential hydrogen (pH), lactic acid bacteria (LAB) population, coliform count, villus height, crypt depth, intestinal segment weight and height, protein digestibility, feed intake, body weight gain (BWG), feed conversion ratio (FCR), and income over feed cost (IOFC). Data were analyzed using analysis of variance, followed by Duncan’s test at a 5% significance level (p<0.05). Results showed that EdteBs supplementation at higher levels (T2 and T3) significantly (p<0.05) increased LAB population, villus height, crypt depth, and intestinal segment weight and height, while pH and coliform counts decreased. Protein digestibility and BWG also significantly improved (p<0.05) in T2 and T3. Both feed intake and BWG increased, particularly in T3, contributing to lower FCR and higher IOFC. In conclusion, EdteBs supplementation enhances intestinal morphology, protein digestibility, and broiler performance, with the most effective level at 0.3%.
