Abstract

ABSTRACT. 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 hermetic sack consistently outperformed other packaging types in maintaining moisture content and the quality of physical properties of rice bran throughout the storage period. The polypropene sack exhibited the poorest performance, suggesting an optimal storage time of less than 60 days for rice bran stored in this type of packaging.

A study was conducted aimed at comparing the growth and production of three species of legumes: Indigofera zollingeriana, Leucaena leucocephala and Gliricidia sepium at a complete randomized design with three treatments (species of tree leguminosae) and 4 replications. The data observed included plant growth (height, number of branches, leaf width); fresh production (total, stem, leaf, leaf/stem ratio) for three cuts and nutrient content (dry matter, crude protein, organic matter, NDF, ADF, crude energy) for two harvests. Plant growth data were analysed by linear regression, while production total and crude protein content were analysed by analysis of variance (ANOVA). The results showed that among the three species of tree legumes, Indigofera zollingeriana was the best in terms of production and nutritional quality. Average production (1,643 g/tree/defoliation) and crude protein content (23.26%) of I. zollingeriana significantly higher than L. leucocephala and G. sepium.

Abstract

ABSTRACT. 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. Pengamatan lebih lanjut terkait dengan buang air kecil dan buang air besar dalam sampel menghasilkan insiden rata-rata sebesar 11,425% dari 70 ekor sapi Bali, yang berfungsi sebagai indikator stres atau ketidaknyamanan. Evaluasi tingkat stres pada sapi di Rumah Potong Hewan Tanah Merah Samarinda, yang terletak di Kalimantan Timur, mengkonfirmasi peningkatan signifikan dalam stres selama proses pemindahan sapi dari zona kandang ke area pemotongan dan penyebaran. Fenomena ini dikaitkan dengan kurangnya pengetahuan di antara peternak tentang penanganan ternak yang optimal dan prinsip kesejahteraan hewan.

Hasil penelitian menunjukkan bahwa penyuntikan enzim papain sangat nyata (P0,01) meningkatkan nilai susut masak daging, nilai terendah terhadap susut masak diperoleh pada perlakuan P0 yaitu 30,9% sedangkan nilai tertinggi terhadap susut masak diperoleh pada perlakuan P1 yaitu 36,6%. Hasil analisis statistik menunjukkan bahwa penyuntikan enzim papain pada ayam jantan petelur memberikan pengaruh nyata (P0,05) terhadap nilai pH daging, nilai pH tertinggi diperoleh pada perlakuan P3 yaitu 5,72 dengan pemberian dosis sebanyak 20 ml enzim papain. Nilai terendah pada perlakuan P0 yaitu 5,54 tanpa pemberian enzim papain.(The antemortem injection effect of papain enzyme on cooking losses and pH values in laying roosters)ABSTRAK. Laying roosters as meat producers have not been used optimally, due to the low tenderness value. Increasing the proportion of shrinkage cooked using enzymes will increase the value of tenderness. This study used a completely randomized design (CRD) with 4 treatments and 4 replications. The treatments used were as follows P0 = control, P1 = 10 ml of papain enzyme, P2 = 15 ml of papain enzyme, and P3 = 20 ml of papain enzyme. The parameters observed in this study were cooking losses and pH. The results showed that the injection of the papain enzyme significantly (P0.01) increased the value of cooking loss in meat, where the lowest value for cooking loss in treatment P0 was 30.9%, while the highest value for cooking loss in treatment P1 was 36.6%. The statistical analysis results showed that the injection of the papain enzyme in laying roosters had a significant effect (P0.05) on the pH value of the meat, where the highest value for the pH level was in the P3 treatment, namely 5.72 with a dose of 20 ml of papain enzyme. The lowest value was in the P0 treatment, namely 5.54 without the administration of the papain enzyme.

Abstract

ABSTRACT. 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. Penelitian ini mengevaluasi pengaruh imbuhan pakan yang mengandung filtrat buah belimbing wuluh, dedak gandum dan S. cerevisiae terhadap produksi telur dan parameter darah ayam petelur selama pasca produksi puncak. Penelitian dilaksanakan berdasarkan rancangan acak lengkap (RAL) menggunakan 224 ekor ayam petelur (umur 80 minggu). Ayam-ayam tersebut didistribusikan ke 4 kelompok perlakuan dan 7 ulangan. Perlakuan tersebut meliputi T0 (pakan basal), T1 (pakan basal + aditif 0,25%), T2 (pakan basal + aditif 0,5%), T3 (pakan basal + aditif 1%). Konsumsi pakan dicatat setiap hari, bobot badan ditimbang setiap minggu dan darah diambil pada hari ke-35 penelitian. Parameter yang diamati dalam penelitian meliputi konsumsi pakan, rasio konversi pakan, produksi telur harian, berat telur, indeks kuning telur, indeks albumin, ketebalan cangkang telur, warna kuning telur dan profil darah lengkap. Hasil penelitian menunjukkan bahwa hen day production menurun (P0,05) seiring dengan peningkatan level aditif dalam pakan. Aditif pakan pada level 0,25% meningkatkan ketebalan cangkang telur (P0,05). Rasio konversi pakan cenderung lebih baik (P=0,08) pada ayam petelur yang menerima aditif sebesar 0,25%. Dibandingkan dengan kontrol, aditif 0,5% menurunkan RDW-SD dan RDW-CV (P0,05) ayam petelur. Sebagai kesimpulan, imbuhan pakan yang mengandung filtrat buah belimbing wuluh, dedak gandum dan S. cerevisiae khususnya pada level 0,25% meningkatkan produksi telur ayam, ketebalan cangkang telur dan rasio konversi pakan.

Penelitian ini menggunakan rancangan acak lengkap yang terdiri atas 3 perlakuan dan 6 ulangan. Materi yang digunakan ialah MNB terdiri dari 50% molases, 30% jerami padi fermentasi, 6% tepung cangkang kerang, 3% garam, 4% urea dan 7% bentonit. Penambahan daun sirih hijau pada MNB sebanyak 0% pada T0, 3% pada T1 dan 6% pada T2. Pemberian pakan terdiri atas konsentrat komersil 65%, rumput gajah 25% dan MNB 10%. Hasil penelitian menunjukkan bahwa penambahan jus daun sirih hijau pada MNB tidak berpengaruh nyata (P0.05) terhadap konsumsi nutrien dan energi, fermentabilitas nutrien pakan serta pemanfaatan energi. Pemberian jus daun sirih hijau sebesar 6% pada MNB tidak berdampak pada proses fermentabilitas dan performa ternak domba.(The biological quality of multi nutrient block with addition of green betel leaf juice on energy utilization of thin tailed sheep)ABSTRAK. Multi Nutrient Block (MNB) is supplement with a high moisture content and classified as intermediate moisture, so it is necessary to add ingredients that have preservative properties, such as green betel leaf. Green betel leaf also has antiprotozoal compound, so it has an impact on the fermentation process in the rumen. The purpose of this study was to examine the biological quality of MNB with green betel leaf to Thin Tailed Sheep in terms of dry matter consumption, daily body weight gain, feed conversion, fermentability and energy utilization. This study used a completely randomized design consisting of 3 treatments and 6 replications. The material used MNB consisting 50% molasses, 30% fermented rice straw, 6% clamshell flour, 3% salt, 4% urea and 7% bentonite, while the addition of green betel leaf was 0% at T0, 3% at T1 and 6% at T2. Feeding consisted of 65% commercial concentrate, 25% elephant grass and 10% MNB. The parameters observed in this study were dry matter consumption, average daily gain, feed conversion, fermentability and energy utilization. The results showed that the addition of green betel leaf juice to MNB had no significant effect (P0.05) on nutrient and energy consumption, fermentability and energy utilization. The conclusion of the study is the addition of green betel leaf juice to MNB until 6% did not impact on the process of fermentability and performance of sheep.
