Simental bulls often experience a decline in production and semen quality in the rainy season, which have a higher humidity and high rainfall. This study aims to maintain nutrient consumption, production and semen quality Simental bulls during the rainy season through the supplementation of Vitamin E, Selenium and Zinc Minerals. The study was conducted in JulyDecember 2012 at the Artificial Insemination Center (BIB) Unggaran. The research material used in this study were 12 males Simental cows BIB Unggaran grouped by age. The experimental design used in this study is a randomized block design (RBD) with 3 treatments T1 (ration + Vit. E), T2 (ration + Vit. E + Se), T3 (ration + Vit. E + Se + Zn) and 4 groups as replicates. Parameters measured were dry matter intake and nutrient consumption, production and semen quality. Cement production was measured from fresh semen volume during the study, whereas semen quality measured motility and concentration of spermatozoa from fresh semen. Data consumption of dry matter and nutrient intake obtained were processed using analysis of variance, followed by Duncan test. While data on production and semen quality were analyzed descriptively.The results showed that the combination of vitamin E supplementation, minerals Selenium and Zinc did not affect dry matter intake, total digestible nutriens and crude protein, but resulted in a decrease in the percentage of shelter, semen volume, sperm motility and concentration smaller than before treatment. Treatment T1, T2 and T3 resulted in a decrease in the number of shelter respectively 41,55%, 19,56% and 13,63% compared to before treatment, whereas a decrease in semen volume unchanged at 44,9 %, 43,7% and 40,99%. Sperm motility due to treatment T1, T2 and T3 respectively decreased sebesaar 55,87%, 22,10% and 13,63% compared to before treatment. In line with sperm motility, sperm concentration in treatment T , T2 and T3, respectively decreased by 49,16%, 22,85% and 14,88%. The conclusion is a combination of vitamin E supplementation, minerals Selenium and Zinc can prevent the decline in cement production, sperm motility and sperm concentration Simental bulls during the rainy season.
This study was conducted to find the rate of body weight ideal study Simental cows to produce production and the best quality fresh semen. The material used in this study were 9 males Simental cows were divided into 3 ranges of body weight as a treatment that is P1 = low body weight (822-878 kg), P2 = moderate weight (910-958 kg) and P3 = body weight high (983-1041 kg PENDAHULUAN Kualitassemen sapi pejantan mempunyai peranan yang sangat penting dalam pelaksanaan perkawinan, baik secara alami maupun Inseminasi Buatan (IB). Inseminasi buatan merupakan teknik perkawinan dengan memasukkan semen segar atau semen beku ke dalam saluran kelamin sapi betina menggunakan alat yang dibuat oleh manusia. Hal ini bertujuan untuk memperbaiki mutu genetik ternak, menghindari penyebaran penyakit kelamin dan meningkatkan jumlah keturunan dari pejantan unggul (Hafez, 2000).Sapi simental merupakan ternak sapi yang memiliki keunggulan dengan tingkat pertumbuhan dan harga jual yang tinggi. Produksi dan kualitas semen yang dihasilkan dari pejantan unggul mempunyai peranan yang penting dalam Inseminasi Buatan, karena faktor yang mempengaruhi keberhasilan IB sangat dipengaruhi oleh kualitas semen yang digunakan dari pejantan yang memiliki produksi dan kualitas semen yang baik.Pejantan unggul yang baik mempunyai produksi dan kualitas semen yang bagus dengan bobot badan yang tinggi. Salah satu faktor yang mempengaruhi produksi dan kualitas semen adalah bobot badan. Menurut Susilawati, et al (1993) produksi dan kualitas semen yang dihasilkan dari seekor pejantan dapat dipengaruhi oleh beberapa faktor, yaitu bobot badan, umur, sifat genetik, frekuensi ejakulasi, pakan, suhu dan musim. Sato (1992) menyatakan bobot badan sapi jantan berhubungan erat dengan ukuran testis, pejantan dengan volume testis dan lingkaran skrotum lebih besar menghasilkan spermatozoa yang juga lebih banyak.Berdasarkan uraian tersebut, maka perlu dilakukan penelitian tentang pengaruh tingkat bobot badan yang berbeda terhadap produksi dan kualitas semen sapi Simental. Penelitian ini bertujuan untuk menemukan bobot badan ideal guna menghasilkan
Pakan merupakan salah satu faktor yang memegang peranan penting dalam suatu usaha peternakan karena hampir 70% biaya produksi adalah dari pakan. Dilarangnya penggunaan antibiotik dalam pakan maka para ahli pakan mencari alternatif penganti pakan seperti pre-probitiok, phytogenic, enzim, imuno mudulator dan beberapa pakan aditif lainnya. Tujuan dari kegiatan pengabdian ini adalah untuk memberikan informasi formulasi pakan berdasarkan sumber daya lokal dan pemberian imbuhan pakan herbal (phytogenic) kepada masyarakat. Kegiatan pengabdian ini dilaksanakan di dua desa yaitu Desa Tumbo Baro, Kecamatan Kuta Malaka (mitra FA Pronak), dan Desa Lamme Garot, Kecamatan Montasik Kabupaten Aceh Besar (mitra Kelasan Express). Dengan kegiatan ini diharapkan adanya peningkatan produktivitas ternak ayam broiler yang dipelihara oleh masyarakat serta berupaya untuk meningkatkan sistem kekebalan tubuh dari ternak yang dipelihara masyarakat dengan memeberikan feed additives herbal sebagai imbuhan pakan. Kegiatan pengabdian kepada masyarakat ini dilakukan secara bertahap, yaitu 1) Tahap persiapan kegiatan, 2) Penyuluhan dan pelatihan, 3) Pembuatan produk yang akan di aplikasikan pada peternak mitra. Hasil dari kegiatan ini adanya peningkatan pengetahuan peternak dalam memformulasi ransum ayam broiler dan penggunakan feed additive herbal sebagai imbuhan pakan dalam pemeliharaan ayam broiler. Kegiatan ini juga memberikan suatu produk ransum yang siap digunakan oleh peternak untuk memenuhi kebutuhan nutrisi dari ayam yang dipelihara.
Administration of antibiotic as feed additive in animal nutrition has been highly concerned due to adverse effect of antibiotic. The purpose of this study was to evaluate administration of liquid probiotic on performances, carcass and giblet characteristics in commercial broiler chickens. Totally 100 mixed sex commercial chickens were randomly distributed to four various treatment groups. Each treatment was administrated various concentration of liquid probiotic in the water (P1=control, P2= 1.0 % of liquid probiotic, P3= 1.5 % of liquid probiotic, and P4= 2.0 % of liquid probiotic) in the drinking water. Broiler chickens were fed commercial feed. Parameters evaluated in this study were broilers performances body weight (BW), feed intake (FI), feed conversion ratio (FCR) and water consumption (WTC) for 4 weeks. The results of the study showed that administration of probiotics was no significantly different (P>0.05) on animal performances (BW, FI and FCR) but significantly different on WTC. Drumstick as part of carcass significantly improved (P<0.05) by administration of liquid probiotics. In conclusion administration of liquid probiotics in broiler had no negative effects on animal performance, carcass and giblet characteristics and it can be applied as alternative feed additives as replacement of antibiotics.
ABSTRACT. Pelepah sawit dapat diolah dengan penambahan filtrat abu sekam padi (FASP) dan filtrat abu tandan kosong (FATK) selanjutnya digunakan sebagai bahan pembuatan wafer. Perbedaan sumber filtrat dan bahan perekat dalam pembuatan wafer memengaruhi fraksi serat dan kualitas fisik. Penelitian bertujuan mengetahui pengaruh sumber filtrat dalam pengolahan pelepah sawit dan bahan perekat berbeda dalam pembuatan wafer terhadap fraksi serat dan kualitas fisik. Rancangan acak lengkap berfaktor 2 x 3 dengan 3 ulangan digunakan dalam penelitian. Faktor F : sumber filtrat : F1= FATK dan F2 = FASP. Faktor L: bahan perekat, L1 = molases; L2. onggok; L3. tepung tapioka. Parameter yang diukur adalah kualitas fisik (kerapatan partikel dan daya serap air) serta fraksi serat (serat detergen asam/acid detergent fiber (ADF), hemiselulosa, selulosa, lignin dan serat detergen netral/neutral detergent fiber (NDF). Data dianalisis dengan analisis variansi selanjutnya analisis ragam dengan uji jarak berganda Duncan/Duncan Multiple Range Test (DMRT). Pelepah sawit yang diolah dengan sumber filtrat berbeda tidak memengaruhi kualitas fisik (daya serap air dan kerapatan partikel) serta kandungan selulosa dan hemiselulosa, tapi memengaruhi (P0,05) kandungan ADF, lignin dan NDF. Penggunaan bahan perekat berbeda dalam pembuatan wafer tidak memengaruhi kerapatan partikel tapi memengaruhi (P0,05) daya serap air dan fraksi serat (ADF, lignin, hemiselulosa, NDF, dan selulosa). Interaksi sumber filtrat dalam pengolahan pelepah sawit dengan bahan perekat dalam pembuatan wafer memengaruhi (P0,05) fraksi serat dan kualitas fisik. Pelepah sawit yang diolah dengan FASP selanjutnya dibuat wafer berbahan perekat molases menghasilkan fraksi serat terbaik (NDF 43,03%; ADF 40,29%; lignin 12,62%; selulosa 24,63%; hemiselulosa 2,74%) dan pelepah sawit yang diolah dengan FATK selanjutnya dibuat wafer berbahan perekat tepung tapioka menghasilkan kualitas fisik terbaik. (The effect of differences of adhesive and filtrates sources on fiber fraction and physical quality of complete ration wafer) ABSTRAK. Palm fronds can be processed with the addition of rice husk ash filtrate (RHAF) and empty bunches ash filtrate (EBHF) and then used as an ingredient in making wafers. Difference source of the filtrate and adhesive material in wafer making affect the fiber fraction and physical quality. The study aimed to determine the effect of the filtrate source in the processing of palm fronds and different adhesives in wafer making on the fiber fraction and physical quality. A completely randomized design with a factorial pattern, 2 x 3 with 3 replications was used in the study. Factor F : filtrate source : F1 = RHAF and F2 = EBHF. Factor L : adhesive material, L1 = molasses; L2 = tapioca by product ; L3 = tapioca flour. The measured parameters are physical quality (particle density and water absorption) and fiber fraction (ADF, hemicellulose, lignin, cellulose, and NDF). Data were analyzed by analysis of variance and the differences were analyzed by DMRT test. Palm fronds treated with different filtrate sources did not affect the physical quality (water absorption and particle density) and cellulose and hemicellulose content, but affected (P0.05) the content of ADF, lignin and NDF. The use of different adhesives in wafer making did not affect particle density but affected (P0.05) water absorption and fiber fraction (ADF, lignin, hemicellulose, NDF, and cellulose). The interaction of the filtrate source in the processing of palm fronds with the adhesive in wafer making affected (P0.05) the fiber fraction and physical quality. Palm fronds which were processed with RHAF then formed wafers with molasses as an adhesive, producing the best fiber fraction (NDF 43.03%; ADF 40.29%; lignin 12.62%; cellulose 24.63%; hemicellulose 2.74%) and palm fronds which were processed with EBAF then formed wafers with tapioca flour adhesive, resulting in the best physical quality.
Ayam Joper merupakan ayam kampung yang berasal dari hasil persilangan antara ayam petelur dan ayam kampung. Berbagai faktor yang mempengaruhi produktivitas dan reproduktivitas ternak termasuk pakan, pengontrolan penyakit, genetik, perkandangan dan manajemen pemeliharan perlu diperhatikan agar mendapat hasil yang optimal. Kegiatan pengabdian kepada masyarakat ini melibatkan 2 mitra pengabdian, yang pertama mitra Local Livestock Farm (LLF) merupakan sebuah kelompok wirausaha yang bergerak dibidang breeding dan hatchery, selanjutnya mitra FA Pronak sudah pernah dilibatkan dengan pembuatan berbagai imbuhan pakan mulai dari probiotik dan phytogenic, produk yang dihasilkan oleh mitra khususnya penyediaan bibit ayam persilangan (hibrida) atau ayam joper (jowo super), sedangkan mitra FA Pronak berperan dalam produksi feed additive. Permasalahan yang terjadi pada mitra adalah indukan yang terbatas, sehingga belum mampu memenuhi permintaan telur fertil yang cenderung meningkat, disamping itu hal yang berkaitan dengan pakan seperti formulasi pakan, penggunaan imbuhan dan manajemen pemeliharaan yang masih belum optimal ditandai dengan angka penetasan yang masih rendah. Berbagai fasilitas untuk mendukung manajemen permeliharan belum tersedia termasuk cooling room menyebabkan telur disimpan pada suhu ruang yang tidak stabil, sehingga kondisi embrio melemah dan menyebabkan rendahnya angka penetasan. Hasil dari kegiatan pengabdian melakukan menajemen pemeliharan ayam joper dengan menggunakan kandang baterai dengan perkawinan secara inseminiasi buatan yang sebelumnya hanya menggunakan kandang koloni dengan perkawinan secara alami, hal ini mampu meningkatkan produktivitas ayam joper dalam memproduksi telur tetas.
This study aimed to evaluate the addition of rejected commercial syrup on the physical quality of silage made from elephant grass and fresh tofu dregs. The making process and harvesting of silage were conducted out at the Laboratory of Nutrition and Feed Technology, Faculty of Agriculture and Animal Husbandry, UIN Suska Riau.

(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).
