Abstract

ABSTRAK. Penelitian ini bertujuan untuk mengoptimalisasi produksi protein mikroba rumen melalui suplementasi ekstrak tepung daun sengon (ETDS) yang mengandung condensed tannin (CT). Penelitian disusun dalam Rancangan Acak Lengkap (RAL) yang terdiri dari 7 perlakuan 5 ulangan menggunakan uji in vitro. Ransum yang digunakan dalam penelitian ini berupa rumput kolonjono (Brachiaria mutica) dan konsentrat. Perlakuan yang diberikan terdiri dari P0 = Ransum tanpa suplementasi ETDS (kontrol); P1 = Ransum + ETDS 1%; P2 = Ransum + ETDS 2%; P3 = Ransum + ETDS 3%; P4 = Ransum + ETDS 4%; P5 = Ransum + ETDS 5%; P6 = Ransum + ETDS 6%. Peubah yang diamati adalah pH, populasi protozoa, dan produksi protein mikroba (PPM). Hasil penelitian menunjukkan perlakuan taraf suplementasi ETDS yang mengandung condensed tannin (CT) tidak berpengaruh (P0.05) terhadap nilai pH, namun berpengaruh nyata (P0.05) terhadap populasi protozoa dan PPM. Terdapat pola hubungan antara taraf suplementasi ETDS dengan populasi protozoa dan produksi protein mikroba dengan model persamaan Y= -0,2896 x2 + 1,2583 x + 8,1633 (R2 = 0,84) dan Y= -0,0764 x2 + 0,41x + 0,8257 (R2= 0,67). Suplementasi ETDS di atas taraf 3% memperlihatkan terjadinya penurunan populasi protozoa. Sementara itu, produksi protein mikroba terus meningkat sampai level suplementasi ETDS pada taraf 3 % dan selanjutnya mengalami penurunan. Dari penelitian ini disimpulkan bahwa suplementasi ETDS pada taraf 3% mampu menghasilkan produksi protein mikroba yang tertinggi. Populasi protozoa mengalami penurunan pada suplementasi ETDS pada taraf di atas 3%.(Optimizing the production of rumen microbial protein through supplementation sengon leaf extracts (Albizia falcataria) containing condensed tannin)ABSTRACT. This study aimed to optimize the rumen microbial protein production through supplementation of sengon leaf extract (SLE) which contains condensed tannin (CT). The study arranged in completely randomized design (CRD) consisting of 7 treatments and 5 replications using in vitro test. The ration used was kolonjono grass (Brachiaria mutica) and concentrate. The treatments consisted of P0 = Ration without supplementation of SLE (control); P1 = Ration + 1% SLE; P2 = Ration + 2% SLE; P3 = Ration + 3% SLE; P4 = Ration + 4% SLE; P5 = Ration + 5% SLE; P6 = Basic Ration + 6% SLE. The observed variables were pH, protozoa population, and microbial protein production (MPP). The results showed that the supplementation of SLE containing CT did not affect (P0.05) the pH value, but significantly (P0.05) affected the protozoa population and MPP. There was a relationship pattern between the supplementation level of SLE with the population of protozoa and MPP with an equation model of Y= -0.2896 x2 + 1.2583 x + 8.1633 (R2 = 0.84) and Y= -0.0764 x2 + 0.41x + 0.8257 (R2= 0.67). Supplementation of SLE above 3% indicates a decrease in protozoa population. Meanwhile, MPP continues to increase until the supplementation level of 3% and subsequently decreases. From this study, it was concluded that supplementation SLE at the level of 3% was able to produce the highest production of microbial proteins. The protozoa population decreased in the supplementation of SLE at levels above 3%.

ABSTRAK. Penelitian bertujuan mengetahui kualitas fisik (warna, aroma, tekstur,) serta sifat fisik (kerapatan, berat jenis, kadar air) wafer dengan perbedaan komposisi substrat (substitusi daun indigofera/DI dengan silase daun pepaya/SDP) dan kemasan berbeda. Rancangan Acak Lengkap (RAL) berfaktor (4x4), 3 ulangan digunakan pada penelitian ini. Faktor H merupakan komposisi substrat (substitusi DI dengan SDP) yaitu, H1= SDP 0% + DI 30%; H2= SDP 2% + DI 28%; H3= SDP 4% + DI 26%; H4 = SDP 6% + DI 24%; faktor N adalah jenis kemasan, N0 = tanpa dikemas; N1= plastik; N2= kertas; N3= karung goni. Kualitas fisik (warna, aroma, tekstur) dan sifat fisik (kadar air, berat jenis, kerapatan) wafer merupakan parameter yang diukur. Hasil penelitian menunjukkan interaksi (P0,01) antara komposisi substrat dan jenis kemasan memengaruhi aroma dan tekstur wafer. Komposisi substrat (P0,01) sangat nyata memengaruhi berat jenis dan aroma wafer. Jenis kemasan (P0,01) sangat nyata memengaruhi kualitas fisik (aroma, warna, tekstur) dan sifat fisik (kadar air). Substitusi 28% DI dengan 2% SDP pada wafer yang dikemas dengan karung goni menghasilkan tekstur wafer terbaik (tidak berlendir, tekstur padat dan kasar dan skor 3,44) dan substitusi 24% DI dengan 6% SDP yang dikemas dengan karung goni menghasilkan aroma wafer terbaik (skor 3,46 aroma khas wafer).(Effect of substitution of indigofera leaves with papaya leaf silage and different types of packaging on the quality and physical properties of wafers)ABSTRACT. The aims of this study to determine the quality of physical (aroma, color, texture) and the properties of physical (compactness, density, moisture content) of wafers with substrate composition (substitution of indigofera leaves/IL with papaya leaf silage/PLS) and different packaging. The study used a factored completely randomized design (CRD) (4x4) with 3 replications. The H factor is the composition of the substrate (substitution of IL with PLS), namely, H1= PLS 0% + IL 30% H2= PLS 2% + IL 28%; H3= PLS 4% + IL 26%; H4 = PLS 6% + IL 24%; factor N is the type of packaging, N0 = no packaging; N1= plastic; N2= paper; N3 = gunny sack. Parameters measured were quality of physical (color, texture, aroma) and properties of physical (specific gravity, density and moisture content) of wafers. The results showed that the interaction between the type of packaging and the composition of the substrate (P0.01) affected the texture and aroma of wafers. Composition of substrate significantly (P0.01) affected the density and aroma of wafers. The type of packaging significantly (P0.01) affected the physical quality (aroma, color, texture) and physical properties (moisture content). Substitution of 28% IL with 2% PLS on wafers with gunny sack resulted in the best texture of wafer (coarse, dense and not slimy texture, score 3.44) and substitution of 24% DI with 6% SDP with gunny sack packaging with the best aroma of wafer (typical wafer aroma, score 3.46).

Abstract

ABSTRACT. This study aimed to determine the effects of using black garlic (BG) instead of fresh garlic (FG) in the ration on the performances and quail blood cholesterol properties. Two hundred 3-week-old female quails were fed five experimental diets for 8 weeks. Each treatment was repeated four times with ten quails each. The treatment diets were: T0= commercial feed (CF) without FG and BG supplementation, T1= CF + 3% FG, T2= CF + 2% FG + 1% BG, T3= CF + 1% FG + 2% BG, and T4= CF + 3% BG. The parameters measured were feed consumption, egg production, egg weight, egg mass, feed conversion ratio, meat quality, and blood cholesterol properties. This study found no significant (P0.05) difference among treatment groups on feed conversion, egg weight, egg mass, total cholesterol, LDL, and HDL. Meat fat decreased significantly (P0.05) by increasing levels of dietary black garlic. A diet with black garlic supplementation significantly increased feed consumption, egg production, and meat protein (P0.05). It is concluded that substituting 100% garlic with black garlic in the diet could increase quail performance without adverse effects on blood cholesterol properties.(Pengaruh penggunaan bawang hitam sebagai pengganti bawang putih dalam ransum terhadap performa dan kadar kolesterol darah puyuh)ABSTRAK. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan bawang hitam (BG) sebagai pengganti bawang putih (FG) dalam ransum terhadap performa dan kolesterol darah puyuh. Dua ratus ekor puyuh betina berumur 3 minggu diberi pakan perlakuan selama 8 minggu dan diulang sebanyak empat kali. Setiap unit perlakuan terdiri dari sepuluh ekor puyuh. Pakan perlakuan adalah: T0= pakan komersial (CF) tanpa suplementasi FG dan BG, T1= CF + 3% FG, T2= CF + 2% FG + 1% BG, T3= CF + 1% FG + 2% BG, dan T4= CF + 3% BG. Parameter yang diukur adalah konsumsi pakan, produksi telur, berat telur, massa telur, rasio konversi pakan, kualitas daging, dan sifat kolesterol darah. Hasil penelitian memperlihatkan bahwa tidak ada pengaruh yang nyata (P0,05) antar kelompok perlakuan terhadap konversi pakan, bobot telur, massa telur, kolesterol total, LDL, dan HDL. Lemak daging menurun secara signifikan (P0,05) dengan peningkatan kadar bawang hitam dalam ransum. Pakan yang disuplementasi dengan bawang hitam nyata meningkatkan konsumsi pakan, produksi telur, dan protein daging (P0,05). Disimpulkan bahwa penggantian 100% bawang putih dengan bawang hitam dalam pakan dapat meningkatkan performa puyuh tanpa memberikan efek negatif terhadap kolesterol darah.

ABSTRACT. Penelitian bertujuan mengkaji pengaruh suplementasi complete rumen modifier (CRM) terhadap aktivitas enzim rumen dan kecernaan pakan domba. Delapan belas ekor domba jantan lokal umur 6 8 bulan dengan bobot rata-rata 18,602,11 kg dibagi menjadi 6 kelompok berdasarkan bobot badan. Masing-masing kelompok tersebut diacak untuk mendapatkan satu dari tiga perlakuan sehingga penelitian menggunakan rancangan acak kelompok (RAK). Konsumsi bahan kering yang diberikan adalah 4% dari bobot badan domba dengan imbangan bahan kering jerami padi amoniasi dan konsentrat adalah 60 dan 40%. Perlakuan yang diuji adalah penambahan CRM 0, 1, dan 2% dari bahan kering ransum untuk P1, P2, dan P3. Peubah yang diamati meliputi aktivitas protease, dan selulase rumen, kecernaan bahan kering, protein kasar, dan serat kasar. Hasil penelitian menunjukkan bahwa suplementasi CRM menurunkan aktivitas protease rumen secara kuadrater (P0,01) dengan aktivitas terendah pada taraf CRM 1,16%. Aktivitas selulase meningkat secara kuadrater (P0,01) dengan aktivitas tertinggi pada taraf CRM 1,06% dengan aktivitas enzim sebesar 0,37 U/mg. Suplementasi CRM tidak berpengaruh (P0,05) terhadap kecernaan bahan kering pakan. Kecernaan protein kasar dan serat kasar meningkat secara kuadratik (P0,01) dengan kecernaan tertinggi dicapai pada taraf CRM 1,43% dan 1,69%. Kesimpulan penelitian, suplementasi CRM sebesar 1% - 2% mampu meningkatkan aktivitas enzim rumen dan kecernaan pakan pada domba. Taraf CRM 1% (P2) merupakan taraf terbaik untuk menghasilkan aktivitas enzim rumen dan kecernaan nutrien secara optimal.(Ruminal enzymes activity and nutrient digestibility of sheep supplemented with Complete Rumen Modifier (CRM))ABSTRAK. This research was carried out to study the supplementation of complete rumen modifier (CRM) to improve feed digestibility and rumen enzymes activity in lambs. Eighteen male local lambs age of 6 8 month with average body weight 18.602.11 kg were grouped into 6 blocks by initial body weight. Each group was randomly got one out of three treatments, so the experiment used randomized block design. Dry matter intake (DMI) was 4% of body weight which consisted of concentrate and ammoniated rice straw with ratio 60:40%. As a treatment were the addition of CRM to the concentrate of 0, 1, and 2% based on the diet for P1, P2, and P3 respectively. The variables measured were rumen enzymes activity (protease, and cellulose) and nutrient digestibility (dry matter, crude protein, and crude fiber). The result showed that CRM supplementation quadratically (P0.01) decreased protease activity with the lowest activity at CRM 1,16% but increase cellulose activity quadratically (P0.01) optimum at level CRM 1,06%. CRM supplementation had no effect (P0.05) on dry matter digestibility. CRM supplementation quadratically (P0.01) improved crude protein dan crude fiber digestibility optimum at CRM 1,47% and 1,69% respectively. In conclusion, CRM at a dose 1% - 2% can improve ruminal enzymes and nutrient digestibility in sheep. CRM dose 1% (P2) was the best dose to optimize specific enzymes activity and nutrient digestibility.

Abstract

ABSTRACT. Bunting semu pada kelinci dapat terjadi karena adanya induksi secara hormonal dan stimulasi fisik yang dapat menyebabkan perubahan pada morfologi saluran reproduksi. Salah satu metode induksi bunting semu adalah melalui injeksi GnRH. Penelitian ini bertujuan mengidentifikasi perubahan terhadap anatomi dan histologi saluran reproduksi pada kelinci lokal bunting semu yang diinduksi dengan penyuntikan GnRH. Dalam penelitian ini digunakan sembilan ekor kelinci betina lokal, berumur 1-2 tahun dengan bobot badan 1,8-2,2 kg. Kelinci yang dibagi ke dalam tiga kelompok perlakuan (n=3) yakni K1, K2, dan K3. Kelompok K1 (kontrol negatif), diinjeksi dengan 0,1 ml NaCl fisiologis tanpa perkawinan; K2 (kontrol positif), kelinci diinduksi dengan 100 IU PMSG, tiga hari kemudian dikawinkan dan diinjeksi 75 IU hCG; dan K3, kelinci diinduksi dengan penyuntikan 5 g GnRH secara intravena. Pada hari ke-8 setelah perlakuan seluruh kelinci disembelih lalu saluran reproduksi diambil untuk pengamatan morfologi dan morfometri oviduk, kornua uteri, serviks uteri dan vagina lalu diproses secara histoteknik dan diwarnai dengan pewarnaan hematoksilin dan eosin untuk pengamatan histologi dan histomorfometri. Panjang oviduk, kornua, dan vagina kelinci memperlihatkan perbedaan yang nyata (P0,05) antar K1 dan K2 dengan K3. Ketebalan lapisan muskularis ampula, lamina propia isthmus, lamina muskularis isthmus, tunika serosa isthmus memperlihatkan perbedaan yang nyata (P0,05) antara K1 dan K2 dengan K3. Tebal lapisan endometrium kornua uterus K2 berbeda sangat nyata (P0,05) dengan K3, namun tidak berbeda nyata (P0,05) dibandingkan K1. Lapisan serosa serviks uteri K1 dan K2 berbeda sangat nyata (P0,05) dengan K3. Histomorfometri vagina kelinci menunjukkan perbedaan yang nyata (P0,05). Berdasarkan hasil penelitian dapat disimpulkan bahwa induksi GnRH tidak menyebabkan perubahan morfologi dan morfometri saluran reproduksi kelinci lokal pada hari ke-8 setelah induksi.(Morphology and morphometry changes of reproductive tract in the pseudo pregnant doesusing GnRH)ABSTRAK. Pseudopregnancy in rabbits can occur due to hormonal induction and physical stimulation that can cause changes in the morphology of the reproductive tract. One method of hormonal induction is GnRH injection. This study aimed to determine the anatomical and histological changes of the reproductive tract in pseudo pregnant local rabbits induced by injection of GnRH. In this study, nine local female rabbits, aged 1-2 years with a body weight of 1.8-2.2 kg, were divided into three treatment groups (n=3), namely, K1 (negative control): injected with 0.1 ml of physiological NaCl without mating, K2 (positive control): injected with 100 IU PMSG and then mated with male rabbits after three days of injection and followed by injection of 75 IU Hcg; K3 injection 5g of GnRH intravena route. On the day-8 after treatment, all rabbits were slaughtered and the reproductive tract was collected for morphological and morphometric observation of the oviduct, uterine horn, uterine cervix, and vagina, and then processed histotechnically and stained with hematoxylin and eosin for histological and histomorphometric observation. The length of oviduct, uterine horn and vagina showed significant different (P0.05) between K1 and K2 with K3. The thickness of the lamina muscularis of ampulla, lamina propia of isthmus, lamina muscularis of isthmus, tunica serous of isthmus showed significant different (P0.05) between K1 and K2 with K3.The thickness of the endometrium of uterine horn was significant different (P0.05) between K2 and K3, but not significantly different (P0.05) with K1. The thickness of tunica serous of servical uterine K1 and K2 was significant different (P0.05) with K3. Vaginal histomorphometry of rabbits was not significantly different (P0.05). It can be concluded that the induction of GnRH did not changes the morphology and histology of the reproductive tract in the local rabbits on the day-8 after treatment.

Abstract

ABSTRACT. Keberhasilan inseminasi buatan dipengaruhi oleh kualitas semen atau motilitas spermatozoa post thawing. Inseminator menggunakan air dingin (28oC) untuk thawing semen beku sedangkan SNI menyarankan thawing semen beku dengan air hangat (37oC) selama 30 detik. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh lama dan suhu thawing pada semen beku sapi Limousin terhadap kualitas semen serta mengetahui perlakuan terbaik dari penelitian ini. Materi yang digunakan adalah 50 straw semen beku sapi Limousin yang diproduksi oleh BBIB Singosari. Metode penelitian yang digunakan adalah eksperimental dengan 5 perlakuan dan 10 ulangan. Variabel yang diamati adalah Motilitas Individu spermatozoa, Viabilitas spermatozoa, Abnormalitas spermatozoa, Konsentrasi dan Total Motilitas Spermatozoa. Data yang diperoleh dianalisis menggunakan analisis ragam Analysis of Variance (ANOVA) dengan Rancangan Acak Kelompok (RAK) kemudian diuji dengan Duncan Multiple Range Test (DMRT) jika terdapat perbedaan nyata. Selanjutnya diuji Chi square untuk variabel motilitas individu, konsentrasi dan total spermatozoa dan dibandingkan dengan SNI untuk semen beku. Dari hasil penelitian, didapatkan bahwa thawing pada suhu 28C dengan lama waktu 60 detik berpengaruh sangat nyata (P0,01) terhadap viabilitas dan berpengaruh nyata (P0,05) pada motilitas individu dan total spermatozoa motil. Sedangkan, konsentrasi dan abnormalitas spermatozoa memberikan hasil tidak berpengaruh nyata (P0,05). Kesimpulan dari penelitian ini adalah thawing dengan air dingin (suhu 28C) selama 60 detik memberikan kualitas semen terbaik setelah thawing.(Quality of Post Thawing Frozen Semen on Limousin Bull Using Cold Water with Different Durations)ABSTRAK. The quality of post-thawing semen influences the success factor of artificial insemination (AI). Inseminators usually used tap water (28C) to thaw the frozen semen, while Indonesian National Standard used warm water (37C) for 30 seconds. This study aims to determine the effect of thawing duration on the frozen semen quality of Limousin Bull and also to know the best treatment between the five treatments of this experiment. The material used in this study was 50 straws of frozen semen produced by Artificial Insemination Center Singosari. The method was an experiment method with five treatments and ten replications. the variables observed were individual motility, sperm viability, sperm abnormality, concentration, and total motile of sperm. The data obtained were analyzed statistically using Analysis of Variance (ANOVA) of Randomized Block Design (RBD) and then using Duncan Multiple Range Test if there is a difference. Then using Chi-Square Test for individual motility, concentration, and total motile of sperm and compared with the Indonesian National Standard of frozen semen. The results show that a temperature of 28C with a duration of 60 seconds is highly significant (P0,01) to viability and significant (P0,05) to individual motility and total motile of sperm. While, the concentration and abnormality of sperm give no significant effect (P0,05). In conclusion, the temperature and duration of thawing at 28C for 60 seconds show the best quality of post-thawing semen.

Abstract

ABSTRACT. Padang penggembalaan yang berkualitas baik akan menghasilkan produktivitas ternak yang optimal. Sistem penanaman hijauan pakan secara monokultur dan polikultur berperanan penting dalam menciptakan padang penggembalaan yang berkualitas baik. Tujuan penelitian adalah untuk mengukur tingkat produksi dan keragaman vegetasi hijauan pakan di padang penggembalaan Balai Pembibitan Ternak Unggul dan Hijauan Pakan Ternak (BPTUHPT) Padang Mengatas berdasarkan sistem penanaman berbeda. Penelitian didesain menggunakan rancangan acak lengkap (RAL) dengan dua perlakuan berdasarkan perbedaan sistem penanaman (monokultur dan polikultur) dan 4 ulangan. Data penelitian dianalisis menggunakan T-test paired sample berdasarkan perbedaan sistem penanaman. Peubah yang diamati adalah karakteristik warna dan pH tanah, tingkat keragaman vegetasi, dan tingkat produksi tanaman pakan. Hasil penelitian menunjukkan bahwa perbedaan sistem penanaman monokultur dan polikultur menghasilkan hasil yang sama baik dan tidak berbeda nyata (P0,05) terhadap pH tanah, produksi biomassa tanaman dan kapasitas tampung. Visualisasi warna tanah adalah cenderung gelap dan pedok didominasi tanaman pakan sesuai desain penanaman, yakni Brachiaria decumbens pada sistem monokultur, Brachiaria decumbens, Panicum maximum, dan Cynodon plectostachyus untuk sistem penanaman polikultur. Kesimpulan dari penelitian bahwa tingkat produksi hijauan dan kapasitas tampung padang penggembalaan tidak berbeda nyata (P0,05) antara perlakuan monokultur dan polikultur, tetapi cenderung lebih tinggi pada perlakuan sistem penanaman polikultur, yakni 4,86 0,88 ST/ha/th dan 5,26 2,42 ST/ha/th. Keragaman vegetasi dari rumput yang dikembangkan berdasarkan indeks nilai penting (INP) adalah tinggi dan dominan Brachiaria decumbens pada sistem monokultur. Begitu juga INP yang tinggi dan dominan dari tanaman Brachiaria decumbens, Panicum maximum, dan Cynodon plectostachyus untuk sistem penanaman polikultur.(Production rate and diversity of forage vegetation at pasture base on planting system)ABSTRAK. Good quality pasture will produce optimum livestock productivity. Forage planting system both monoculture and polyculture have important role to provide good quality pasture. The objective of the research was to evaluate production rate and forage diversity at Center of Animal Breeding and Forage (BPTUHPT) Padang Mengatas based on different planting system. A completely randomized design with 2 treatments based on planting system (monoculture and polyculture) and 4 replication were applied for the research. Data was analyzed by T-test paired sample based on planting system. Parameters observed were color characteristics and soil pH, vegetation diversity rate, and forage productivity. Research shows that planting system by monoculture and polyculture provide similar result (P0,05) for soil pH, biomass production and carrying capacity. Soil color visualization tend to be darker and paddock was dominated by Brachiaria decumbens for monoculture system, meanwhile Brachiaria decumbens, Panicum maximum, dan Cynodon plectostachyus were dominant for polyculture system. Production rate and carrying capacity of pasture were not significantly different (P0,05) for both monoculture and polyculture system, but tend to be higher on polyculture system. The average production rate were 4,860,88 AU/ha/yr for monoculture system and 5,262,42 AU/ha/yr for polyculture system. Diversity of forage vegetation according to the Importance Value Index (IVI) was high and dominance for Brachiaria decumbens at monoculture system. In addition, it was similar result for Brachiaria decumbens, Panicum maximum, dan Cynodon plectostachyus with polyculture system.
