Abstract

  This community service activity aimed to enhance the knowledge and skills of goat and sheep farmers in Cibeureum Wetan Village in early detection of livestock health and processing forage feed into silage to support year-round feed sustainability. The implementation method was participatory, involving counseling sessions, demonstrations, and hands-on practice in making silage using local materials and conducting basic livestock health checks. The participants consisted of 27 farmers from three hamlets, with materials delivered by resource persons from the Regional Technical Implementation Unit (UPTD) of Sumedang Regency and students from the IPB University KKN-T Innovation program. The effectiveness of the activity was evaluated through a 10-question pre-test and post-test to measure knowledge improvement, as well as observation of participants’ practical skills. The evaluation results showed an average score increase of 6.92 points (8.25%) from the initial score, along with improved participants’ skills in conducting livestock health examinations and preparing silage according to procedures. This activity also generated sustainability initiatives, including the establishment of a small-scale silage production unit, utilization of local raw materials, and collaboration with external partners. In conclusion, the training successfully increased participants’ knowledge, improved their technical competencies, and created new entrepreneurial opportunities that support food security in the village.

Abstract

Growth hormone (GH) that plays an important role in growth, reproduction, seawater adaptation, and immune function was isolated and sequenced from humpback grouper, Cromileptes altivelis. The cDNA was isolated from pituitary using RT-PCR. The 618 bp open reading frame encodes a 205 amino acid (aa) protein, which represents an 18 aa signal peptide followed by a 187 aa mature GH polypeptide. The fragment contained conserved domain of somatotropin–1, somatotropin–2, casein kinase II phosphorylation, protein kinase C phosphorylation, N–myristoylation and N–glycosilation. The similarity of deduced protein of humpback grouper GH was 65.0 - 89.5% with other fishes

Abstract

Triploidization is a polyploidization technique used to produce fish with improved growth, while hybridization is another method to enhance genetic quality through crosses within or between species. This study evaluated the growth performance of allotriploid catfish at the seed stage. The experiment was conducted for 45 days at the Laboratory of Reproduction and Genetics of Aquatic Organisms, Bogor Agricultural University, using a completely randomized design with four treatments and three replications. The treatments consisted of allotriploid, autotriploid, hybrid diploid, and diploid fish. Ploidy analysis showed that allotriploid and autotriploid fish had up to three nucleoli per cell, while hybrid diploid and diploid fish had a maximum of two. Growth results indicated that allotriploid fish achieved the highest final weight (4.68±0.12 g) and length (2.79 ± 0.16 inches), followed by hybrid diploid, autotriploid, and diploid fish. ANOVA results confirmed significant differences in final weight and length among treatments, indicating that ploidy manipulation and hybridization had a substantial impact on growth. However, feed conversion ratio and survival rate did not differ significantly (P > 0.05). Overall, the findings indicate that allotriploid catfish seeds showed superior growth performance compared to autotriploid, hybrid diploid, and diploid fish.

Abstract

Cannibalism is one of the causes low survival rate white snapper fry due to its aggressiveness. Melatonin is a hormone that can modulate aggressive interactions in fish. This study aims to evaluate effect of melatonin hormone on the level cannibalism sea bass. This study used completely randomized design (CRD) consisting of four treatments and three replications, namely control (without melatonin hormone administration), melatonin doses of 5, 10, and 15 µg/g fish. Hormone administration was done orally through feed supplementation. Sea bass fry used were 2.82 ± 0.41 cm average length and 0.53 ± 0.08 g average weight. Stocking density was 2 fish/L. Sea bass were reared for 30 days with flow through system and fed three times a day in restricted manner (Feeding rate 15%). The results showed the administration of melatonin hormone can reduce level cannibalism, increase melatonin hormone levels, increase estradiol 17β hormone, and have no effect on body glucose levels sea bass. Melatonin dose 10 µg/g fish can reduce level cannibalism by 40.67% (P<0.05). The highest total cannibalism was found in the control treatment with a value of 58.67% (P <0.05). The administration of melatonin hormone did not affect the growth body weight and length of sea bass (P>0.05). Increasing dose melatonin beyond 10 µg/g fish tends to increase cannibalism. These results indicate the administration of melatonin hormone at a dose of 10 µg/g fish is the optimal dose to reduce cannibalism and increase fry survival, which is expected to increase the productivity of sea bass hatcheries. Keywords: aggressiveness, Asian seabass, cannibalism, melatonin   Abstrak Kanibalisme merupakan salah satu penyebab rendahnya tingkat kelangsungan hidup benih kakap putih akibat sifat agresivitasnya. Hormon melatonin merupakan hormon yang dapat memodulasi interaksi agresif pada ikan. Penelitian ini bertujuan untuk mengevaluasi pengaruh hormon melatonin terhadap tingkat kanibalisme ikan kakap putih. Penelitian ini menggunakan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dan 3 kali ulangan, yaitu kontrol (tanpa pemberian hormon melatonin), melatonin dosis 5, 10, dan 15 µg/g ikan. Pemberian hormon dilakukan secara oral melalui suplementasi pakan. Benih kakap putih yang digunakan berukuran panjang rata-rata 2,82 ± 0,41 cm dan berat rata-rata 0,53± 0,08 g. Padat tebar yaitu 2 ekor/L. Benih kakap putih dipelihara selama 30 hari dengan sistem flow through dan pemberian pakan sebanyak tiga kali sehari secara restricted (Feeding rate 15%). Hasil penelitian menunjukkan bahwa pemberian hormon melatonin dapat menurunkan tingkat kanibalisme, meningkatkan kadar hormon melatonin, cenderung meningkatkan hormon estradiol 17β, dan tidak berpengaruh terhadap kadar glukosa tubuh benih kakap putih. Melatonin dosis 10 µg/g ikan dapat mengurangi tingkat kanibalisme sebesar 40,67% (P<0,05). Total kanibalisme tertinggi terdapat pada perlakuan kontrol dengan nilai sebesar 58,67% (P<0,05). Pemberian hormon melatonin tidak berpengaruh terhadap pertumbuhan bobot dan panjang tubuh benih kakap putih (P>0,05). Peningkatan dosis melatonin melebihi 10 µg/g ikan cendrung meningkatkan kanibalisme. Hasil ini menunjukkan bahwa pemberian hormon melatonin dosis 10 µg/g ikan merupakan dosis optimal untuk mengurangi kanibalisme dan meningkatkan kelangsungan hidup benih, sehingga diharapkan  dapat meningkatkan produktivitas pembenihan kakap putih.

Abstract

One of the problems faced in catfish hatcheries is that the reproductive cycle does not occur throughout the year, so that available male broodstocks with mature gonads are rare. Cryopreservation is a method of storing spermatozoa with the help of diluents and cryoprotectants in frozen conditions to maintain the quality of spermatozoa. Cryopreservation has a negative effect due to the influence of reactive oxygen species (ROS) which causes a decrease in the quality of spermatozoa. An alternative that can be done is using antioxidants in the form of vitamin C and cryoprotectants such as vitamin E. This research aims to test the effectiveness of adding vitamin E and vitamin C to catfish (Clarias gariepinus) sperm on post-cryopreservation sperm quality. The test fish were catfish that had mature gonads and were injected with the ovaprim hormone for final approval. This study consisted of eight treatments and three replications, namely control (fresh sperm), DMSO 10%, DC1 (vitamin C dose 1 mg/mL), DC2 (vitamin C dose 2.5 mg/mL), and DC3 (vitamin C dose 4 mg/mL), DMSO 10%, DE 1 (vitamin E 2 mg/mL), DE2 (vitamin E 4 mg/mL), DE3 (vitamin E 6 mg/mL). The parameters observed include sperm motility, sperm viability, degree of egg fertilization, and degree of egg hatching. Sperm cryopreservation is carried out for one hour. The results showed that the motility, viability, and degree of egg fertilization in the vitamin C and vitamin E treatments were lower (P<0.05) than the control and 10% DMSO as the basic control. Keywords: Clarias gariepinus, cryopreservation, vitamin C, vitamin E   Abstrak Salah satu permasalahan yang dihadapi dalam pembenihan ikan lele adalah siklus reproduksi tidak terjadi sepanjang tahun sehingga ketersediaan induk jantan dengan gonad matang menjadi langka. Kriopreservasi merupakan salah satu metode penyimpanan spermatozoa dengan bantuan bahan pengencer dan krioprotektan dalam kondisi beku untuk mempertahankan kualitas spermatozoa. Kriopreservasi memiliki dampak negatif akibat adanya pengaruh reactive oxygen species (ROS) yang menyebabkan penurunan kualitas spermatozoa. Alternatif yang dapat dilakukan adalah dengan menggunakan antioksidan berupa vitamin C dan krioprotektan seperti vitamin E. Penelitian ini bertujuan untuk menguji efektivitas penambahan vitamin E dan vitamin C pada sperma ikan lele (Clarias gariepinus) terhadap kualitas sperma pascakriopreservasi. Ikan uji adalah ikan lele yang telah memiliki gonad matang dan disuntik hormon ovaprim untuk persetujuan akhir. Penelitian ini terdiri dari delapan perlakuan dan tiga kali ulangan, yaitu kontrol (sperma segar), DMSO 10%, DC1 (dosis vitamin C 1 mg/mL), DC2 (dosis vitamin C 2,5 mg/mL), dan DC3 (dosis vitamin C 4 mg/mL), DMSO 10%, DE 1 (vitamin E 2 mg/mL), DE2 (vitamin E 4 mg/mL), DE3 (vitamin E 6 mg/mL). Parameter yang diamati meliputi motilitas sperma, viabilitas sperma, derajat fertilisasi sel telur dan derajat penetasan sel telur. Kriopreservasi sperma dilakukan selama satu jam. Hasil penelitian menunjukkan bahwa motilitas, viabilitas dan derajat fertilisasi sel telur pada perlakuan vitamin C dan vitamin E lebih rendah (P<0,05) dibandingkan kontrol dan DMSO 10% sebagai kontrol dasar.
