Dedak padi merupakan salah satu bahan pakan yang digunakan untuk pakan ternak, namun terdapat kendala dalam penggunaannya, salah satunya adalah rendahnya daya simpan. Penelitian ini bertujuan untuk menentukan pengaruh waktu penyimpanan dan jenis kemasan terhadap perubahan kadar air dan kualitas sifat fisik dedak padi. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan pola faktorial 3 x 4 dan 4 ulangan. Faktor-faktor yang diteliti terdiri dari A: waktu simpan (0, 30, 60 hari) dan B: jenis kemasan (karung plastik polipropena, karung goni, karung plastik polietilena, dan karung hermetik). Parameter yang diamati adalah perubahan kadar air (KA), kerapatan tumpukan (KT), kerapatan pemadatan tumpukan (KPT) dan berat jenis (BJ). Data dianalisis dengan uji sidik ragam dan bila terjadi perbedaan (p0,05) dilanjutkan dengan uji Tukey. Jumlah serangga yang tumbuh dianalisis secara deskriptif. Hasil penelitian menunjukkan semua perlakuan berpengaruh nyata (p0,05) dengan interaksi nyata (p0,05) terhadap semua peubah. Waktu simpan nyata (p0,05) menaikkan kadar air dan nyata (p0,05) menurunkan nilai KT, KPT dan BJ dedak padi. Jenis karung hermetik seiring waktu penyimpanan nyata (p0,05) merupakan karung terbaik dan karung polipropena merupakan karung terburuk dalam hal mempertahankan kualitas dedak padi. Jumlah serangga semakin meningkat seiring waktu simpan dengan jumlah paling sedikit ditemukan pada karung hermetik. Dapat disimpulkan penggunaan kemasan hermetik lebih baik dalam mempertahankan kandungan kadar air dan nilai sifat fisik dengan waktu optimal penyimpanan kurang dari 60 hari.  (Effect of storage time and packaging type on moisture content and physical properties of rice bran) ABSTRAK. Rice bran is a valuable feed ingredient for animal feed, but its low storage stability poses challenges for its long-term utilization. This study investigates the effects of storage time and packaging type on moisture content and the quality of physical properties of rice bran. A Completely Randomized Design (CRD) factorial design (3 x 4) with 4 replications was employed. Factor A examined storage time (0, 30, 60 days), and factor B explored different packaging types (polypropylene sack, burlap sack, polyethylene sack, and hermetic sack). The observed variables were moisture content, bulk density, tapped density, and specific gravity. Insect infestation was also assessed descriptively. ANOVA was used to analyze the data, and the Tukey test was applied in cases of significant differences (p0.05). The results revealed that both treatments and their interaction had significant effects (p0.05) on all measured parameters. Storage time significantly (p0.05) increased moisture content and decreased (p0.05) bulk density, tapped density, and specific gravity of rice bran. Insect populations increased with storage time, with the lowest infestation observed in the hermetic sack.

The present study evaluated the effect of feed additives containing Averrhoa bilimbi L. fruit filtrate, wheat bran, and Saccharomyces cerevisiae on egg production and blood parameters of laying hens during post-peak production. The experiment was carried out according to a completely randomized design with 224 hens (80 weeks old). The hens were randomly distributed to 4 treatments and 7 replications. The treatments included T0 (basal feed), T1 (basal feed + 0.25% additive), T2 (basal feed + 0.5% additive), T3 (basal feed + 1% additive). Feed intake was recorded daily, body weight was determined weekly, and blood was collected on day 35 of the experiment. The variables measured included feed intake, feed conversion ratio, hen day production, egg weight, yolk index, albumin index, eggshell thickness, yolk color, and complete blood counts. Results showed that hen-day production decreased (P0.05) as the level of additives increased in the feed. Dietary inclusion of additive at 0.25% increased (P0.05) eggshell thickness. The feed conversion ratio tended (P=0.08) to be better in hens receiving additives at 0.25%. Compared to control, additive at 0.5% decreased (P0.05) red blood cell distribution width-standard deviation (RDW-SD) and red blood cell distribution width-coefficient variation (RDW-CV) of laying hens. In conclusion, novel feed additives containing A. bilimbi L. fruit filtrate, wheat bran, and S. cerevisiae, particularly at 0.25% of the diet improved hen day egg production, eggshell thickness, and feed conversion ratio.  (Pengaruh novel feed additive terhadap produksi telur dan parameter darah ayam petelur pasca puncak produksi) ABSTRAK.

The heightened demand for domestic beef has emerged in response to an expanding populace and heightened public interest in meat consumption. The principal objective of this investigation was to assess cardiac activity, as inferred from heart rate data, through the application of rigorous statistical methodologies and meticulous sampling techniques. The study comprised 70 Bali cattle sourced from the Samarinda Slaughterhouse (RPH), with statistical analysis facilitated by the utilization of the Z Test. Examination of the heart rate data indicated a notable degree of variability. Upon conducting the Z Test, a statistically significant finding was ascertained with p0.05, signifying the acceptance of H1. This, in turn, signified that the heart rate data exhibited an elevation in stress levels. Conversely, H0 was categorically refuted, implying an absence of heightened heart rate between the enclosure environment and the site of slaughter. Further observations centered on urination and defecation within the sample, yielding an average incidence of 11.425% amongst the 70 Bali cattle, serving as an indicator of stress or discomfort. The evaluation of stress levels in cattle within the Tanah Merah Samarinda Animal Slaughterhouse, situated in East Kalimantan, corroborated a significant surge in stress during the transition of cattle from the enclosure zone to the slaughter and dispersal area. This phenomenon is attributed to the deficiency in knowledge among stockpersons concerning optimal livestock handling and the principles of animal welfare.  (Pengukuran tingkat stres pada sapi pra dan pasca penyembelihan di rumah potong hewan Tanah Merah Samarinda, Provinsi Kalimantan Timur, Indonesia) ABSTRAK. Permintaan yang meningkat untuk daging sapi dalam negeri muncul sebagai respons terhadap pertumbuhan penduduk yang terus meningkat dan minat publik yang tinggi dalam konsumsi daging. Tujuan utama dari penelitian ini adalah untuk menilai aktivitas jantung, seperti yang disimpulkan dari data denyut jantung, melalui penerapan metodologi statistik yang ketat dan teknik pengambilan sampel yang cermat. Penelitian ini melibatkan 70 ekor sapi Bali yang diperoleh dari Rumah Potong Hewan (RPH) Samarinda, dengan analisis statistik dilakukan dengan menggunakan Uji Z. Pemeriksaan data denyut jantung mengindikasikan tingkat variasi yang signifikan. Setelah melakukan Uji Z, temuan yang signifikan secara statistik ditemukan dengan p0,05, menunjukkan penerimaan H1. Ini, pada gilirannya, menunjukkan bahwa data denyut jantung menunjukkan peningkatan tingkat stres. Sebaliknya, H0 secara tegas ditolak, mengimplikasikan ketiadaan peningkatan denyut jantung antara lingkungan kandang dan lokasi pemotongan.

Hasil penelitian menunjukkan bahwa R2 =65,3 yang artinya sebesar 65,3% variabel yang diamati memengaruhi angka kebuntingan sedangkan 34,7% dipengaruhi oleh faktor lain. Jumlah sapi betina di tiap lokasi penelitian secara signifikan (P0,05) memengaruhi keberhasilan inseminasi buatan. Berdasarkan uraian tersebut maka dapat disimpulkan bahwa secara nyata jumlah sapi betina memengaruhi keberhasilan IB dan secara simultan bersama variabel pengetahuan peternak dalam mendeteksi berahi, ketepatan waktu IB, jarak lokasi peternak dengan petugas IB serta BCS sebesar 65,3% memengaruhi keberhasilan IB di Kabupaten Deli Serdang.  (Analysis of successful factors for artificial insemination cattle in the reproduction optimization program in Deli Serdang Regency, North Sumatera) ABSTRAK. Artificial Insemination is one of the biotechnology in field of livestock reproduction that allows humans to inbreed female livestock without needed of male cattle. The method of this research was survey method, using primary data and secondary data. Primary data was obtained by distributing questionnaires and interviews directly to farmers as additional information, while secondary data obtained from inseminators related to the results of artificial insemination in the Deli Serdang District. The questionnaire used included questions about cattle characteristics such as pregnancy status, knowledge of breeders in detecting heat, body condition scores, number of cows, location distance and breeder profiles with 95 respondent breeders from three districts. Data were analyzed using multiple linear regression tests. The results showed that as many as 5 variables were observed simultaneously only 65.3% affected the pregnancy rate while 34.7% were influenced by other factors. The conclusion of the study is that the factors that influence the success of artificial insemination in cattle in Deli Serdang Regency are the number of cows in the sub-districts studied.","PeriodicalId":30910,"journal":{"name":"Jurnal Agripet","volume":"148 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139327329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brachiaria humidicola merupakan jenis rumput utama di padang penggembalaan Unit Pendidikan dan Penelitian Peternakan Jonggol (UP3J) Fakultas Peternakan, IPB University. Diperlukan strategi untuk meningkatkan produksi biomassa tanaman sesuai potensi genetiknya. Tujuan penelitian adalah upaya peningkatan produktivitas rumput Brachiaria humidicola di padang penggembalaan UP3J melalui suplementasi pupuk feses ayam yang ideal. Penelitian di desain dengan rancangan acak lengkap (RAL) yang terdiri dari 5 perlakuan K = urea 150 kg ha-1, FA05 = 5 ton ha-1 pupuk organik + urea 75 kg ha-1, FA10 = 10 ton ha-1 pupuk organik + urea 75 kg ha-1, FA15 = 15 ton ha-1 pupuk organik + urea 75 kg ha-1, FA20 = 20 ton ha-1 pupuk organik + urea 75 kg ha-1. Hasil Penelitian menunjukkan bahwa perlakuan FA20 sangat nyata (p0,01) meningkatkan tampilan morfologi tanaman dan produksi biomassanya. Kesimpulan dari penelitian adalah suplementasi pupuk feses ayam hingga dosis 20 ton ha-1 tidak mengubah status pH tanah. Suplemantasi pupuk feses ayam dosis 20 ton ha-1 adalah yang terbaik dalam meningkatkan pertumbuhan morfologi rumput Brachiaria humidicola (jumlah tunas, jumlah stolon, panjang stolon dan tinggi tanaman) dan produksi biomassa tanaman. Suplementasi pupuk feses ayam ≥ 10 ton ha-1 menghasilkan dominasi warna daun hijau muda sebagai visualisasi dari daun muda.  (Improvement of grass production Brachiaria humidicola in grazing fields through supplementation of organic fertilizer poultry manure) ABSTRAK. Brachiaria humidicola is one of grass that predominantly grown at pasture at Jonggol Animal Science Teaching and Research Unit (Jastru), Faculty of Animal Science, IPB University. Improvement strategy should be done to increase biomass production of the grass. The objective of the research was to improve Brachiaria humidicola grass productivity with supplementation of fertilizer from broiler chicken manure. Completely randomized design with five different treatments, namely K = urea 150 kg ha-1, FA05 = 5 ton ha-1 of organic fertilizer + urea 75 kg ha-1, FA10 = 10 ton ha-1 of organic fertilizer + urea 75 kg ha-1, FA15 = 15 ton ha-1 of organic fertilizer + urea 75 kg ha-1, FA20 = 20 ton ha-1 of organic fertilizer + urea 75 kg ha-1. Result shows that FA20 treatment produce the highest production of biomass and improve plant morphology appearance compare to another treatment (P0,01). Supplementation of organic fertilizer up to 20 ton ha-1 did not change soil pH status. In addition, it can improve growth of the Brachiaria humidicola morphology (number of shoots and stolons, stolons length and plant height) and biosmass production. Furthermore, Supplementation of organic fertilizer more than 10 ton ha-1 produce leaf with predominantly light green color as a visualization of the young leaves.","PeriodicalId":30910,"journal":{"name":"Jurnal Agripet","volume":"132 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139329701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
