Abstract

The identification of estrous signs is an important step in livestock reproduction to allow the appropriate mating time. This study investigated soybean oil as a source of vitamin E and its effect on thin-tailed ewes. Observation was performed in one-year-old, non-pregnant thin-tailed ewes with mean weight of ±30 kg. Reproductive factors registered included estrous signs (vulvar color, mucus secretion, vaginal temperature), estrous cycle length, and pregnancy rate. The experiment was conducted using a Completely Randomized Design (CRD) with three treatments and six replications (0 mL, 1.8 mL, 3.6 mL). Before observation, soybean oil was applied for seven days. Data were analyzed using Kruskal–Wallis test for vulvar color and mucus secretion, ANOVA for vaginal temperature and estrous cycle, and descriptive analysis for pregnancy rate. In conclusion, the results indicated a significant effect of soybean oil supplementation on estrous signs (P<0.05), as indicated by a vulvar color score of 2.83±0.40 (red), a vaginal temperature of 38.81±0.29°C, estrous cycle duration of 18.00±0.89 days, and a pregnancy rate of 83.33%. The mucus secretion score was not significantly affected by soybean oil supplementation (P>0.05). Soybean oil at a dose of 1.8 mL clarified estrous signs, shortened estrous cycle, and increased pregnancy rate in thin-tailed ewes.

Abstract

Asam pedas kikil sapi, dikenal secara lokal sebagai asam pedas belulang merupakan kuliner khas Kalimantan Barat yang tergolong low acid food dengan aktivitas air tinggi, sehingga rentan rusak pada suhu ruang. Sterilisasi menggunakan panci presto modifikasi pada produk dalam kemasan retort pouch berpotensi memperpanjang umur simpan sekaligus menjaga mutu produk. Penelitian ini bertujuan mengevaluasi karakteristik organoleptik dan fisiokimia asam pedas kikil sapi dalam kemasan retort pouch setelah sterilisasi menggunakan panci presto. Penelitian dilakukan secara eksperimen laboratorium menggunakan Rancangan Acak Lengkap dengan tiga perlakuan waktu sterilisasi, yaitu F₀=4 menit (P1), F₀=7 menit (P2), F₀=10 menit (P3) pada suhu 111°C dan tekanan 0,4–0,5 bar. Parameter yang dianalisis meliputi pH, mutu organoleptik, serta analisis proksimat pada perlakuan terbaik. Data dianalisis menggunakan ANOVA dan uji lanjut Duncan (α=0,05). Hasil menunjukkan pH produk berada pada kisaran 5,83–5,85 yang mengonfirmasi karakter low acid food. Waktu sterilisasi berpengaruh signifikan (p<0,05) terhadap warna, rasa, tekstur dan penerimaan keseluruhan, tetapi tidak berpengaruh signifikan (p>0,05) terhadap aroma. Perlakuan F₀ 4 menit (P1) menghasilkan skor organoleptik tertinggi dengan kadar air 84,68%, abu 1,01%, lemak 5,78%, protein 7,23%, dan karbohidrat 1,30%. Temuan ini menunjukkan bahwa sterilisasi berdurasi singkat mampu mempertahankan mutu sensori dan karakteristik fisikokimia asam pedas kikil sapi.

Abstract

Subsektor peternakan memiliki peran penting dalam penyediaan pangan hewani, agribisnis, dan penyerapan tenaga kerja. Salah satu komoditas yang berkontribusi besar dalam subsektor peternakan adalah unggas. Kabupaten Magelang merupakan salah satu daerah di Provinsi Jawa Tengah yang memiliki potensi besar dalam mengembangkan komoditas unggas. Peran komoditas unggas di kabupaten ini dianalisis dengan menggunakan data sekunder dari BPS periode tahun 2020-2024. Metode analisis yang digunakan adalah analisis Location Quotient (LQ) untuk mengetahui komoditas unggas basis, analisis shift share untuk melihat kinerja komoditas unggas, serta analisis tren produktivitas telur dan daging unggas di Kabupaten Magelang. Hasilnya adalah ayam kampung, ayam ras petelur, itik, itik manila, dan burung puyuh merupakan komoditas unggas basis di Kabupaten Magelang. Komoditas ayam ras petelur, ayam ras pedaging, dan burung puyuh termasuk dalam kelompok unggas dengan pertumbuhan cepat dan berdaya saing (Kuadran I, analisis shift share). Selain itu, tren produktivitas telur positif pada komoditas ayam ras petelur, itik, dan ayam kampung, sementara tren produktivitas daging positif pada komoditas itik. Dengan demikian, perlu adanya dukungan input-hilir agar produksi tetap stabil dan penguatan kebijakan untuk pengembangan komoditas unggas di Kabupaten Magelang.

Abstract

Kebutuhan daging sapi dalam negeri ditopang melalui produksi domestik dan impor. Impor daging sapi yang dilakukan Indonesia sebagian besar dalam bentuk daging sapi beku tanpa tulang Namun di sisi lain, Indonesia juga melakukan ekspor. Penelitian ini bertujuan untuk mengkaji apakah aktivitas impor atau ekspor yang mendominasi perdagangan daging sapi beku tanpa tulang Indonesia. Selain itu, penelitian ini juga mengkaji bagaimana tingkat ketergantungan impor Indonesia terhadap komoditas tersebut. Penelitian ini menggunakan data impor, ekspor, dan produksi di tahun 2021 hingga tahun 2024 yang diperoleh melalui UN Comtrade dan BPS. Data diolah dan dianlisis dengan menggunakan pendekatan Indeks Spesialisasi Perdagangan (ISP) untuk mengetahui peran Indonesia dalam perdagangan dunia. Selain itu untuk mengetahui tingkat ketergantungan impor, analisis yang digunakan adalah Import Dependency Ratio (IDR). Berdasarkan hasil analisis ISP dan IDR, Indonesia pada tahun 2024 merupakan negara dengan dominasi aktivitas ekspor dibandingkan dengan impor. Tingkat ketergantungan impor terhadap daging sapi beku tanpa tulang tergolong rendah selama empat tahun terakhir yang mengindikasikan bahwa produksi domestik masih mampu mencukupi kebutuhan dalam negeri. Hasil penelitian ini diharapkan dapat memberikan pandangan dan rekomendasi gagasan kepada pemerintah bahwa laju pertumbuhan impor daging sapi beku tanpa tulang dapat ditekan dengan peningkatan produksi dan penetapan harga optimal sehingga menguntungkan produsen daging sapi dan konsumen.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan tepung daun singkong fermentasi dalam ransum komersial terhadap persentase karkas, organ viseral, dan karakteristik fisikokimia daging paha ayam joper. Sebanyak 80 ekor DOC ayam joper dibagi secara acak ke dalam 20 petak pecobaan yang menggunakan rancangan acak lengkap. Perlakuan penelitian adalah level penambahan tepung daun singkong fermentasi dalam ransum komersil, yaitu 0%, 5%, 10%, 15%, dan 20%. Peubah yang diamati meliputi persentase karkas, persentase hati, persentase gizzard, pH, daya ikat air, dan susut masak daging. Hasil penelitian menunjukkan bahwa penambahan tepung daun singkong fermentasi berpengaruh nyata (P < 0,05) terhadap pH dan daya ikat air daging ayam joper, namun tidak berpengaruh nyata (P > 0,05) terhadap persentase karkas, persentase hati, persentase gizzard, dan susut masak. Perlakua 20% tepung daun singkong fermentasi menghasilkan daging ayam joper dengan pH tertinggi dan daya ikat air terendah. Kesimpulannya adalah tepung daun singkong fermentasi dapat digunakan dalam ransum komersil hingga 20% tanpa memberikan efek negatif pada persentase karkas, organ viseral. Namun, untuk stabilitas fisikokimia daging khususnya pH dan daya ikat air, penambahannya sebaiknya tidak lebih 15%.

Abstract

This study aims to evaluate the addition of Dieng carica seeds in complete feed. The parameters observed were slaughter weight, carcass, edible carcass, net viscera, edible viscera, and eight commercial cuts. The materials used were eighteen local lambs (3 months, 10.68 ± 1.30 kg), pellet feed consisting of carica seeds, pakchong grass, and concentrate. The study used a Completely Randomized Design with three treatments and six replications. The treatments consisted of A: 5%, B: 12.5% ​​and C: 20% carica seed level. Data were analyzed using analysis of variance. The results showed that the level of carica seeds had a significant effect on the slaughter and carcass weight, edible carcass, weight of leg, shoulder, shank, breast, and breast percentage, but relatively the same in other parameters. The slaughter weight of A was lower than B and C, but B was relatively the same with C. The carcass weight and edible carcass at A were lower than B and C, but B and C were relatively the same. The shoulder, shank, and breast weights at A were lower than B and C. The leg weight at A was lower than C, but B was relatively the same as A and C. The percentage of commercial breast cuts at A was lower than at B and C. From the research results, it can be concluded that feed containing 12.5-20% carica seeds can increase the edible carcass weight, the weight of shoulder, shank, breast and leg, and percentage of breast cuts. Keywords: Carica seeds, Carcass, Edible carcass, Viscera, Commercial cuts

Abstract

This study aimed to evaluate the effect of pollard as an additive on the physical quality of silage made from kepok banana (Musa paradisiaca) peel waste and to determine the optimum level of pollard inclusion. The study employed an experimental method using a Completely Randomized Design (CRD) consisting of four treatments and four replications. The treatments were P0 (banana peel waste without pollard), P1 (10% pollard), P2 (20% pollard), and P3 (30% pollard). The observed parameters included color, aroma, texture, mold occurrence, and silage pH. Organoleptic data were analyzed using the Kruskal Wallis test followed by the Mann–Whitney test, while pH data were analyzed using analysis of variance (ANOVA) followed by Duncan's Multiple Range Test. The results showed that the addition of pollard had a highly significant effect (P<0.01) on the color, aroma, texture, and pH value of the silage, but had no significant effect (P>0.05) on mold occurrence. The inclusion of pollard improved the physical quality of the silage, as indicated by a yellowish-green color, a fresh acidic aroma characteristic of fermentation, a denser texture, and lower pH values compared with silage prepared without pollard. The silage pH ranged from 4.13 to 4.65. The best treatment was obtained with 20% pollard inclusion (P2), which resulted in color, texture, aroma, and mold occurrence scores of 3.13, 4.00, 3.87, and 3.97, respectively, with a pH value of 4.13, indicating excellent silage quality. Therefore, the inclusion of 20% pollard is an effective additive for improving the physical quality of silage produced from kepok banana peel waste.

Abstract

To achieve meat self-sufficiency by 2026, increasing the production of forage the basal feed for ruminants is crucial. Pakchong grass, a promising forage crop, suffers from reduced productivity due to water limitations and climate change induced temperature rises and heatwaves. Mycorrhizae, through symbiosis with plant roots, have the potential to assist plants in coping with heat stress. This study aimed to examine the interaction between mycorrhizae and Pakchong grass and its impact on nutrient utilization and productivity. A completely randomized design was employed with four treatments: P0 (control), P1 (10 g mycorrhizae), P2 (20 g mycorrhizae), and P3 (30 g mycorrhizae). Data were analyzed using One-Way ANOVA, followed by DMRT if significant differences were found. The cultivation period lasted 40 days, followed by a 7-day drought stress treatment. Observed parameters included NPK levels in the growing medium, mycorrhizal infection rates, biomass productivity, plant height, number of leaves, number of tillers, dry matter (DM) content, and nutrient uptake efficiency. The results showed that mycorrhizal inoculation at various levels had a significant effect (P<0.05) on AMF infection in roots and Pakchong plant height, but no significant effect (P>0.05) on the number of leaves, number of tillers, DM content, or nutrient uptake efficiency. These findings indicate that while mycorrhizae can form a successful symbiosis with Pakchong roots, their effectiveness in enhancing grass productivity is limited under conditions of severe heat stress.

Abstract

High commercial feed costs necessitate the use of alternative feed ingredients such as Azolla pinnata. This study evaluated the inclusion of Trichoderma harzianum-fermented Azolla pinnata Meal (TAT) on growth performance, nutrient digestibility, and hematology of male Muscovy ducks (Cairina moschata). A total of 120 male ducks (4 weeks old) were assigned to 4 dietary treatments (P0: 0% TAT, P1: 7.5% TAT, P2: 15% TAT, and P3: 22.5% TAT) with 5 replications in a Completely Randomized Design (CRD). Parameters observed included body weight gain (BWG), feed intake, feed conversion ratio (FCR), dry matter digestibility (DMD), crude protein digestibility (CPD), and hematological profiles (RBC, WBC, Hb, Ht). Data were analyzed using ANOVA and Duncan's test. Results indicated that P2 (15% TAT) achieved the highest BWG (1842.30 ± 32.15 g) and best FCR (3.21 ± 0.08) compared to P0 control (BWG: 1685.12 ± 28.40 g; FCR: 3.65 ± 0.11). Crude protein digestibility reached its peak in P2 (74.82 ± 1.12%). Blood values remained within healthy normal ranges across all treatments. However, 22.5% TAT (P3) decreased growth due to high fiber content. It is concluded that replacing commercial feed with up to 15% TAT effectively improves growth performance and feed efficiency in Muscovy ducks.
