Evaluasi Nutrisi Pellet Ayam Pedaging Berbahan Kulit Ari Biji Kedelai Hasil Fermentasi Menggunakan Effective Microorganisme-4 dengan Penyimpanan Berbeda

Tujuan untuk mengetahui kualitas nutrisi pellet yang disimpan dengan bahan kulit ari biji kedelai yang difermentasi menggunakan EM4. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 5 ulangan. Peubah yang diamati adalah kualitas nutrisi pellet meliputi (kadar air, protein kasar, lemak kasar, serat kasar, abu dan bahan ekstrak tanpa nitrogen). Penelitian ini dilaksanakan di Laboratorium Ilmu Nurisi dan Kimia Fakultas Pertanian dan Peternakan Universitas Islam Negeri Sultan Syarif Kasim Riau dan Laboratorium Hasil Perikanan Universitas Riau. Hasil penelitian ini adalah semakin lama waktu simpan dapat mempertahankan kualitas nutrisi dilihat dari protein kasar, lemak kasar dan BETN dan tidak berpengaruh nyata (P>0.05) terhadap kadar air, serat kasar, dan abu yang dihasilkan. Kesimpulan dari penelitian ini menunjukkan bahwa lama penyimpanan 8 minggu merupakan perlakuan terbaik dalam meningkatkan kualitas nutrisi pellet dilihat dari kandungan protein kasar sebesar 20,70%

Nilai Nutrisi Silase Limbah Sayur Kol dengan Penambahan Dedak Padi dan Lama Fermentasi yang Berbeda

Limbah sayur kol memiliki kadar air yang tinggi sehingga cepat mengalami pembusukan maka salah satu alternatif penggunaannya dengan silase. Penelitian ini bertujuan untuk mengetahui nilai nutrisi yang terkandung dalam silase limbah sayur kol dengan penambahan dedak padi dan lama fermentasi yang berbeda. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Pola Faktorial (2x3) yaitu faktor A adalah level penambahan dedak padi 0% dan 35%. Faktor B yaitu lama fermentasi 0 hari, 7 hari dan 14 hari. Parameter yang diukur adalah Bahan Kering (BK), Protein Kasar (PK), Lemak Kasar (LK), Abu dan Bahan Ekstrak Tanpa Nitrogen (BETN). Hasil penelitian menunjukan pemberian substrat dedak padi 35% memberikan pengaruh sangat nyata (P0.05). Lama fermentasi tidak berpengaruh nyata (P<0.05) Terhadap Bahan Kering (BK), Lemak Kasar (LK), Serat Kasar (SK) dan Bahan Ekstrak Tanpa Nitrogen (BETN) dan memberikan pengaruh sangat nyata (P<0.01) terhadap kandungan penurunan Abu. Perlakuan terbaik terdapat pada level penambahan dedak padi 35% dan lama fermentasi 14 hari dilihat dari penurunan kandungan abu sebesar 11,38% Kata kunci: Kualitas nutrisi, silase, limbah sayur kol, fermentas

Peforma Burung Puyuh (Coturnix coturnix japonica) Periode Grower yang Diberi Pakan Berbahan Tepung Daun Ubi Kayu

Peforma burung puyuh yang baik membutuhkan pakan dan manajemen pakan yang baik. Penelitian ini bertujuan mengetahui performa burung puyuh periode grower yang diberi pakan berbahan tepung daun ubi kayu meliputi konsumsi ransum, pertambahan bobot badan, konversi ransum dan nilai IOFC (Income over feed cost). Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 Perlakuan (T0 = Ransum tanpa penambahan tepung daun ubi kayu, T1= 3% penambahan tepung daun ubi kayu, T2= 6% penambahan tepung daun ubi kayu dan T3= 9% penambahan tepung daun ubi kayu) dan 4 ulangan. Penelitian menunjukkan bahwa penambahan tepung daun ubi kayu dengan level 0%, 3%, 6% dan 9% berpengaruh nyata (P0,05) terhadap pertambahan bobot badan dan konversi ransum puyuh. Kesimpulan dari penelitian ini adalah penambahan tepung daun ubi kayu hingga level 9% mampu meningkatkan konsumsi ransum, tetapi belum mampu meningkatkan pertambahan bobot badan, nilai IOFC (Income over feed cost) dan menurunkan konversi ransum.

Kualitas Nutrisi dan Fraksi Serat Wafer Ransum Komplit Subtitusi Dedak Jagung dengan Level Persentase Ampas Sagu yang Berbeda

Sago waste is the result of agricultural waste whose use as feed is still very limited even though the amount is quite large but sago waste has a high crude fiber content, and low protein content so that is needs further processing, one of which is processing become a wafer complete ration. The study used the Complete Randomized Design (CDR), method with 4 treatments and 4 replications, which consisted of P0: complete wafer ration + 0% sago waste, P1: complete wafer ration + 10% sago waste, P2: complete wafer ration + 20% sago waste, P3: complete wafer ration + 30% sago waste. The parameters measured were the content of dry matter, crude protein, crude fat, crude fiber, ash content and nitrogen free extract, neutral detergen fiber, acid detergen fiber, acid detergen lignin, cellulosa and hemicellulosa. The result showed that the of the sago waste level to 30% can improve the dry matter, crude fiber, ash content and reduced the nitrogen free extract acid detergen fiber and acid detergen lignin. The addition of 30% sago waste level is the best treatment because can decrease neutral detergent fiber 74.09%-57.5%, acid detergent fiber 67.64%-54.23%, dan acid detergent lignin 39.03%-27.17%.

Effect of the COVID-19 pandemic on surgery for indeterminate thyroid nodules (THYCOVID): a retrospective, international, multicentre, cross-sectional study.

Since its outbreak in early 2020, the COVID-19 pandemic has diverted resources from non-urgent and elective procedures, leading to diagnosis and treatment delays, with an increased number of neoplasms at advanced stages worldwide. The aims of this study were to quantify the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic; and to evaluate whether delays in surgery led to an increased occurrence of aggressive tumours. In this retrospective, international, cross-sectional study, centres were invited to participate in June 22, 2022; each centre joining the study was asked to provide data from medical records on all surgical thyroidectomies consecutively performed from Jan 1, 2019, to Dec 31, 2021. Patients with indeterminate thyroid nodules were divided into three groups according to when they underwent surgery: from Jan 1, 2019, to Feb 29, 2020 (global prepandemic phase), from March 1, 2020, to May 31, 2021 (pandemic escalation phase), and from June 1 to Dec 31, 2021 (pandemic decrease phase). The main outcomes were, for each phase, the number of surgeries for indeterminate thyroid nodules, and in patients with a postoperative diagnosis of thyroid cancers, the occurrence of tumours larger than 10 mm, extrathyroidal extension, lymph node metastases, vascular invasion, distant metastases, and tumours at high risk of structural disease recurrence. Univariate analysis was used to compare the probability of aggressive thyroid features between the first and third study phases. The study was registered on ClinicalTrials.gov, NCT05178186. Data from 157 centres (n=49 countries) on 87 467 patients who underwent surgery for benign and malignant thyroid disease were collected, of whom 22 974 patients (18 052 [78·6%] female patients and 4922 [21·4%] male patients) received surgery for indeterminate thyroid nodules. We observed a significant reduction in surgery for indeterminate thyroid nodules during the pandemic escalation phase (median monthly surgeries per centre, 1·4 [IQR 0·6-3·4]) compared with the prepandemic phase (2·0 [0·9-3·7]; p&lt;0·0001) and pandemic decrease phase (2·3 [1·0-5·0]; p&lt;0·0001). Compared with the prepandemic phase, in the pandemic decrease phase we observed an increased occurrence of thyroid tumours larger than 10 mm (2554 [69·0%] of 3704 vs 1515 [71·5%] of 2119; OR 1·1 [95% CI 1·0-1·3]; p=0·042), lymph node metastases (343 [9·3%] vs 264 [12·5%]; OR 1·4 [1·2-1·7]; p=0·0001), and tumours at high risk of structural disease recurrence (203 [5·7%] of 3584 vs 155 [7·7%] of 2006; OR 1·4 [1·1-1·7]; p=0·0039). Our study suggests that the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic period could have led to an increased occurrence of aggressive thyroid tumours. However, other compelling hypotheses, including increased selection of patients with aggressive malignancies during this period, should be considered. We suggest that surgery for indeterminate thyroid nodules should no longer be postponed even in future instances of pandemic escalation. None
