Abstract

This research aimed to study long-term addition natural herbal: mangosteen pericarp meal and non-herbal: vitamin E in the diet on digestive organs, accessory organs, reproductive organs, and carcass of laying hens. A total of 160 laying hens of Lohman strains (24-wk-old) the observation was conducted for 11 weeks. Designs used are a completely randomized design with four treatments and four replications (10 birds each). The treatments consisted of R0 (control diet), R1 (R0 + 1 g MPM/kg ration), R2 (R0 + 2 g MPM/kg ration) and R3 (R0 + 200 mg VE/kg ration). The variabel observation were digestive organs (percentage of crop, heart, gizzard, spleen, kidney, small intestine), accesory organs (percentage of liver and bile), reproductive organs, body weight and carcass of laying hens. The results showed that all of treatments (RO, R1, R2, and R3)  did not affect (P>0.05) internal organs (percentage of crop, heart, gizzard, spleen, kidney, small intestine), accesory organs (percentage of liver and bile), reproductive organs, body weight and carcass of laying hens. In conclusion, long-term addition of mangosteen pericarp meal 1-2 g/kg ration and vitamin E 200 mg/kg in the diet no adversed effect on digestive organs, accesory organs, reproductive organs, body weight and carcass of laying hens.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh suplementasi tepung kulit manggis (TKM) dan Vitamin E (VE) di dalam ransum ayam ras petelur terhadap kualitas fisik telur selama penyimpanan pada waktu dan suhu yang berbeda. Ayam petelur diberi perlakuan pakan yaitu : R0 (ransum kontrol), R1 (R0 +1 g TKM/Kg ransum), R2 (R0 + 2 g TKM/Kg ransum) dan R3 (R0 + 200 mg VE/Kg ransum). Rancangan yang digunakan adalah rancangan acak lengkap pola faktorial 4 x 3 x 2 dengan 4 ulangan. Faktor pertama yaitu ransum, faktor kedua yaitu: waktu penyimpanan (1, 2 dan 3 minggu) dan faktor ketiga yaitu suhu penyimpanan pada refrigerator (4,13oC dan 22,50%) dan suhu ruang (27, 47oC dan 76,17%). Variabel yang diamati adalah: berat telur, persentase kerabang telur, persentase kuning telur, persentase putih telur, tebal kerabang, warna kuning telur dan Haught unit (HU). Hasil penelitian menunjukkan bahwa interaksi antara ransum, waktu dan suhu selama penyimpanan sangat nyata (P<0,01) menurunkan warna kuning telur. Waktu dan suhu penyimpanan sangat nyata (P<0,01) menurunkan HU dan meningkatkan persentase kuning telur. Interaksi waktu dan suhu penyimpanan nyata (P<0,05) menurunkan persentase putih telur. Tebal kerabang nyata (P<0,05) meningkat dipengaruhi oleh ransum dan sangat nyata (P<0,01) meningkat dipengaruhi oleh waktu penyimpanan. Berat telur dan persentase kerabang telur tidak dipengaruhi oleh ransum, waktu dan suhu penyimpanan. Kesimpulan penelitian adalah suplementasi tepung kulit manggis dan Vitamin E di dalam ransum ayam ras petelur strain Lohmann secara umum tidak mempengaruhi kualitas fisik telur (kecuali warna kuning telur dan tebal kerabang) yang disimpan pada waktu dan suhu yang berbeda. Kualitas fisik telur lebih utama dipengaruhi oleh waktu dan suhu penyimpanan yang berbeda. Suhu dan kelembaban terbaik untuk penyimpanan telur adalah 4,13oC dan 22,50% pada refrigerator, pada kondisi ini telur dapat disimpan selama 21 hari.

Abstract

Plantation by-products can be used as livestock feed with proper processing, optimizing the feed efficiency of palm kernel cake (PKC), empty oil palm bunch (EOPB), and acacia sawdust (AS). This study aimed to improve the usability of the byproducts as alternative feed through the Pleurotus ostreatus fermentation process. To this end, a 3×3 factorial, completely randomized design was applied. Factor A was the type of substrate, P1 = PKC, P2 = EOFB and P3 = AS. Factor B was the fermentation period, T1 = 0 d, T2 = 30 d and T3 = 60 d. The collected data were analyzed using analysis of variance (ANOVA), and the significantly different result was further tested using Duncan Test. The observed variables include Neutral Detergent Fiber (NDF), acid detergent fiber (ADF), hemicellulose, pH value, dry matter digestibility (DMD), organic matter digestibility (OMD), N-NH 3 , and volatile fatty acids (VFA). The study result showed that P.ostreatus mushroom in various substrate types did not significantly affect the fiber fraction of NDF, ADF, and Hemicellulose. This study also found that the interaction of substrate type and fermentation duration significantly affects dry matter digestibility, organic matter digestibility, N-NH 3 production, and VFA values. This study concluded P. ostreotus increased the nutritional value and digestibility of the by- product from plantation processing. The best fermentation duration was 60 d PKC was found to have the highest digestibility value, and the best interaction was found in PKC with 60 d of fermentation.

Abstract

Pakchong elephant grass (PEG) is a super fodder with significant nutritional content and high production levels. The purpose of this research is to quantify the growth and yield of PEG through nitrogen fertilizer engineering with different dosages and repeated fertilization methods. A completely randomized design (CRD) was employed in the investigation, with 4 different levels of urea dosage (100; 200; 300; and 400 N kg/ha). And 10 replicates. ANOVA was used to evaluate the data, and Duncan's Multiple Range Test was then used to determine whether the treatments were substantially different (P<0.05). The findings demonstrated that the addition of nitrogen fertilizer at dosages of 200–400 N kg/ha was better compared to 100 N kg/ha at the end of maintenance (8 weeks after planting) for the quantity of leaves, leaf length, the height of plant, production of both fresh and dry biomass of PEG. There were no significant effect (P>0.05) in nitrogen fertilizer levels at the end of maintenance (8 weeks after planting) for leaf width, leaf chlorophyll content, stem sugar content, quantity of tillers, and the leaf-to-stem ratio of PEG. The research's conclusion indicates that adding nitrogen fertilizer up to 400 N kg/ha is generally safe and feasible for the growth and production of PEG. A nitrogen fertilizer dosage of 200 N kg/ha is optimal to meet PEG's growth and production needs.
