Cauda epididymal spermatozoa could be used as an alternative source of gamete in the application of various reproductive technologies, since the spermatozoa is motile and has ability for fertilizing the oocyte. Theobjective of this research was to examine the effectivity of maltose in maintaining viability of ettawa crossbreed goat epididymal spermatozoa preserved at 3–5oC. Five testis with epididymides of ettawa crossbreed goat were obtained from slaughterhouse. Epididymal spermatozoa was collected by the combination of slicing, flushing and tissues pressure of cauda epididymides with physiological saline (0.9% NaCl). Collected-spermatozoa wasdivided in equal volume into three tubes and diluted with Tris extender containing 20% egg yolk (control), Tris extender + 0.3 g maltose/100 ml (M0.3), and Tris extender + 0.6 g maltose/100 ml (M0.6), respectively. Dilutedspermatozoa was stored in refrigerator at 3–5oC. Quality of diluted-spermatozoa including percentages of motile spermatozoa (MS) and live spermatozoa (LS) were evaluated every day during storage at 3–5oC for four days. Data were analyzed using completely randomized design with three treatments and five replicates. Means were compared significant difference test at 0.05 significant level. Results of this study showed that mean spermatozoaconcentration, percentage of MS, percentage of LS, and percentage of abnormal spermatozoa of ettawa crossbreed goat fresh epididymal spermatozoa were 3,220 million cell/ml, 70%, 81%, and 4.3%, respectively. At day-5 of storage, percentages of MS and LS for M0.3 (38 and 60.4%) and M0.6 (38 and 57.2%) were significantly (P<0.05) higher than control (32 and 55.4%). In conclusion, addition of 0.3 and 0.6% maltose in Tris extender could be maintained viability of ettawa crossbreed goat epididymal spermatozoa preserved at 3–5oC forthree days.

Abstract

The objective of this study was to examine the effect of seminal plasma on viability of Boer goat spermatozoa and effectiveness of sugar palm juice as an alternative extender during preservation at 5ºC. Semen of two Boer goats were collected using an artificial vagina. Fresh semen were evaluated and divided in equal volume into four tubes. Semen in the first and second tubes diluted with 80% sugar palm juice + 20% egg yolk (P1) and Andromed (P2), respectively. Semen in the third and fourth tubes were centrifuged with 3,000 RPM for 20 minutes, and the supernatant removed. diluted with 80% sugar palm juice + 20% egg yolk (P3) and Andromed (P4), respectively. Diluted-semen were preserved in refrigerator at 5oC, and quality of the spermatozoa including motile spermatozoa (MS), live spermatozoa (LS), and intact plasma membrane (IPM) were evaluated every day for four days. Results of this study showed that at day-2 preservation, mean percentages of MS, LS, and IPM for P2 (72, 83.4, and 83.4%), P3 (72, 82.6, and 82.2%), and P4 (72, 83, 83.8%) were significantly (P<0.05) higher than P1 (3, 24.8, and 25.2%). At day-3 preservation, mean percentages of MS, LS, and IPM for P2 (57, 65.6, and 69.6%) was significantly (P<0.05) higher than P3 (21, 34.8, and 31.8%), P4 (22, 33.6, and 31.2%), and P1 (0, 0, and 0%). In conclusion, semen of Boer goat to be preserved with extender containing egg yolk should be removed seminal plasma. Sugar palm juice containing egg yolk could be used as an extender for Boer goat semen, but should be applied in the AI program immediately after the semen is diluted.

Abstract

Alabio duck is a superior laying duck breed from Alabio, South Kalimantan. The government program of crossing Alabio duck with other duck breeds to produce commercial hybrid ducks was followed by local breeders, where the crossbreed was carried out without direction and occurred in the genetic source area of Alabio ducks. This has resulted in a decrease in the performance of Alabio duck, a fewer number of duck breeders, and reduce the quality of processed products,  especially salted eggs. To conserve and maintain the purity of Alabio ducks in their genetic source area, it is necessary to educate local breeders about the potential of Alabio ducks as a source of germplasm with high selling value. The objective of this activity was to educate the breeders to avoid uncontrolled crossbreeding of Alabio duck. This community service was carried out through observations, interviews, and Focus Group Discussion in Harapan Bahagia Farmer Group in Murung Asam Village, Alabio, HSU Regency. Issues identification showed that the decline in Alabio ducks population was caused by the unavailability of good Alabio ducklings, the higher price of Alabio duck compared to other duck breeds and the smaller egg size of Alabio duck. However, it was agreed on the superiority of Alabio duck, namely resistance to avian influenza disease, longer egg shelf life, longer egg production period, and a more savory taste of meat. It was concluded that conserving Alabio duck breed was necessary because Alabio ducks were always used as parents in crossing with other duck breeds. Many ways could be carried out to conserve Alabio duck, among others were by well-planned and under control crossbreeding, eliminating subsidies of hybrid ducklings produced by BPTU, utilizing local feed ingredients, and technology adoption to increase the quality of Alabio duck products. --- Itik Alabio merupakan itik petelur unggul yang berasal dari Alabio, Kalimantan Selatan. Program pemerintah menyilangkan itik Alabio dengan rumpun itik lain untuk menghasilkan itik hibrida komersial ternyata diikuti oleh  peternak, di mana peternak melakukan persilangan secara tidak terarah, tidak terencana dan   dilakukan di  daerah sumber bibit itik Alabio.  Hal ini berakibat menurunnya mutu bibit itik, semakin sedikitnya jumlah peternak itik Alabio, serta menurunnya kualitas produk itik Alabio, terutama telur asin.  Untuk menjaga kelestarian dan tetap terpeliharanya kemurnian itik Alabio di daerah sumber bibit, maka perlu dilakukan edukasi kepada peternak  mengenai potensi itik Alabio sebagai sumber plasma nutfah lokal yang bernilai jual tinggi. Tujuan kegiatan  iniadalah melakukan edukasi peternak agar tidak melakukan persilangan itik Alabio secara tidak terkontrol dan tidak terencana sehingga kemurnian genetik itik alabio dapat dipertahankan. Pengabdian kepada masyarakat dilakukan melalui observasi, wawancara dan Focus Group Discussion dengan Kelompok Peternak Itik Harapan Bahagia di Desa Murung Asam, Alabio, Kabupaten HSU. Identifikasi isu memperlihatkan bahwa berkurangnya populasi itik Alabio disebabkan tidak tersedianya bibit yang baik, harga bibit itik Alabio lebih mahal dibanding rumpun itik lain, serta ukuran telur yang lebih kecil. Meskipun demikian diketahui juga keunggulan itik Alabio, yaitu tahan terhadap penyakit flu burung, daya simpan telur lebih lama, masa produksi telur lebih panjang dan rasa daging yang lebih gurih. Disimpulkan bahwa menjaga kemurnian itik Alabio murni sangatlah penting karena itik Alabio selalu dipergunakan sebagai tetua dalam persilangan dengan rumpun itik lain. Upaya pelestarian itik Alabio dapat dilakukan antara lain dengan penghapusan subsidi harga bibit itik hibrida yang dihasilkan BPTU, penggunaan bahan pakan lokal dalam ransum, serta adopsi teknologi untuk peningkatan kualitas produk itik Alabio.

Abstract

Abstract The large component of feed costs in the production cost of laying ducks requires farmers to use the cheaper feed ingredients but can still meet nutritional needs and maintain good production performance of alabio laying ducks. This study aims to determine the effect of the use of duckweeds in diets on the production performance of alabio ducks including egg production, feed consumption, feed conversion, income over feed-cost, egg weight, yolk-color, and cholesterol levels in duck eggs.The study used a Completely Randomized Design (CRD) method with four treatments and five replications, each of which consisted of three Alabio laying ducks. The research treatments were P0 = 0% the use of duck weed, P1 = 10% the use of duck weed int, P2 = 20% the use of duck weed, and P3 = 30% the use of duck weed for every of the diet treatment. The results showed that the use of duck weeds (Lemna minor) up to 30% in the feed diet had no effect on the amount of egg production, percentage of egg production, feed conversion, egg weight, and IOFC values but it affected the feed consumption, yolk color and cholesterol content of alabio duck eggs. The feed consumptions were not different from the control diet until 20% use of duck weeds, but decreased at 30% due to increased crude fiber feed. The Yolk color scores increased and the egg cholesterol content decreased with increasing use of duck weeds in feed diets. Duck weed has a great opportunity to be used as a source of protein feed. Keywords: Duckweed; Feed-diets; Laying alabio-ducks; Production performance Abstrak Besarnya komponen biaya pakan dalam biaya produksi itik petelur menuntut peternak menggunakan sumber bahan pakan yang murah tapi tetap dapat memenuhi kebutuhan nutrisi dan mempertahankan performans produksi itik alabio petelur yang baik. Penelitian ini bertujuan untuk mengetahui manfaat penggunaan gulma bebek dalam ransum terhadap performans produksi itik alabio meliputi produksi telur, konsumsi ransum, konversi pakan, income over feed-cost, bobot. telur, yolk-color (warna kuning telur), dan kadar kolesterol di dalam telur itik sebagai alternatif bahan pakan sumber protein. Penelitian menggunakan metode Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan lima ulangan, dimana setiap ulangan terdiri dari tiga ekor itik alabio petelur. Perlakuan penelitian yaitu P0 = 0 % gulma bebek, P1 = 10 % gulma bebek, P2 = 20 % gulma bebek dan P3 = 30 % gulma bebek digunakan pada tiap ransum perlakuan. Hasil menunjukkan bahwa penggunaan gulma bebek (Lemna minor) hingga 30% dalam ransum tidak berpengaruh pada jumlah produksi telur, persentasi produksi telur, konversi pakan, bobot telur, dan nilai IOFC tapi berpengaruh terhadap konsumsi ransum, yolk color dan kandungan kolesterol telur itik alabio. Konsumsi ransum tidak berbeda dengan pakan kontrol hingga penggunaan gulma bebek 20%, tapi menurun pada 30% karena meningkatnya serat kasar pakan. Score yolk color meningkat dan kandungan kolesterol telur menurun dengan meningkatnya penggunaan gulma bebek dalam ransum. Gulma bebek berpeluang besar dapat digunakan sebagai bahan pakan sumber protein. Kata Kunci: Gulma bebek; Itik alabio petelur; Performans produksi; Ransum

Abstract

A research was conducted in order to investigate the effects of supplementing methionineand lysine as carnitin precursor in feed on the performances and fat contain of broiler chickens.Completely randomized design, 4 treatments and 4 replications (total 32 male chickens) wasutilized in the experiment. Control feed (meet NRC recommendation) and water were provided adlib during experiment (43-days). Treatments used in the experiment started at 22-days of age wereR0 (Control Feed), R1 (Control Feed + carnitin precursor type A (L-HCl Lysin 0,50 % + DLMethionine0,57 %)), R2 (Control Feed + carnitin precursor B (L-HCl Lysine 2 % + DLMethionine0,57 %)), and R3 (Control Feed + carnitin precursor C (L-HCl Lysin 1,50 % + DLMethionine0,19 %)). Data were gathered as parameters including body weight, growth rate, feedconsumption, feed conversion, carcass percentage, abdominal fat, and cholesterol contain. Datawas analyzed used ANOVA, then DMRT. Results show that supplementing methionine andlysine as karnitin precursor in feed affected increasing body weight and growth rate, decreasingfeed consumption, abdominal fat and cholesterol contain, but it did not affect feed conversion andcarcass yield. Based on results, the treatment R2 carnitin precursor B can be recommended as bestchoice feed for reducing abdominal fat and cholesterol contain but still produce high carcass yieldand feed efficiency.

Abstract

India ink was used to examine the role of the yolk stalk lumen as a distinct pathway between the yolk sac and gut through the first 5 d of post-hatch growth in broiler chicks. Two hundred and sixteen newly hatched broiler chicks were equally divided into three treatment groups; gavaged via the esophagus (TRT1), injected in the yolk sac (TRT2) with 0.2 mL of water-based black India ink and  third group of chicks were used as untreated controls (TRT0). Tissue samples of the small intestine, yolk sac, and yolk stalk were removed and fixed in 10% buffered neutral formalin and were processed routinely, embedded in paraffin, sectioned at 5 to 6 µm, and stained with hematoxylin and eosin. The relative concentration of India ink in each of the tissue preparations was detected with a light microscope and assigned a relative score between 0 and 3, with 0 indicating the lowest and 3 the highest amount of ink present. The results show India ink was able to pass from the yolk sac through the yolk stalk and into the intestine, but was not able to pass from the intestine into the yolk stalk or yolk sac. It was concluded that India ink was useful materials in establishing that the yolk stalk provides a direct one-way passage by which material in the yolk sac may move into the intestine of broiler chicks during the first 5-d after hatching.

Abstract

The trial was conducted with the purpose to investigate the usefulness 51Cr labeled microspheres as tracers in yolk absorption and or its rate absorption through yolk stalk.  In the trial,  20 broiler chicks were injected in the yolk sac on Day 0 with with 0.2 ml of radioactive 51Cr labelled microspheres suspended in physiological saline. Injection was made with directly through the abdominal wall into the underlying yolk sac. At 1300 h each day for five days, four chicks were sacrificed at random by cervical dislocation. For each chick, total body  weight, and the weight and level of radiation (cpm) from the following organs were determined: total body, carcass, intestine, liver,  yolk sac, gizzard, kidney, and excreta. The level of radiation from tissues were obtained with the use of a High Energy Gamma Scintillator Probe containing NaI crystal. Results show body weight, and relative intestine, and excreta weight increased between 1 and 5 days; conversely, relative yolk sac weight decreased between 1 and 5 days.  Relative yolk stalk weight peaked on Day 4, but was not significantly different from that at Day 1. Relative cpm of the liver, yolk sac, yolk stalk, and excreta were influenced by day of age. The level of radiation was significantly higher in the yolk sac, kidney, and excreta than in the carcass, intestine, liver, blood, and gizzard. It was concluded that significant amounts of yolk may be absorbed and pass through the yolk stalk into the intestine through 5 days of age in post-hatch chicks and the rate of movement increases through 5 days post-hatch, particularly after Day 3.
