Abstract

The population of anoa, which is an endemic fauna to Indonesia, was getting decrease caused by the illegal hunting and deforestation. Anoa is included in endangered species by IUCN, and Appendix I by CITES. The experiment aimed to characterize the seminal plasma contents and to cryopreserve the anoa semen for artificial insemination application in captivity. The experiment was carried out in Taman Safari Indonesia (Bogor). Semen was collected from 2 anesthetized males (4-10 years) by electroejaculation. Seminal plasma gained by centrifugation of ejaculate (3000 rpm, 20 minutes), and then was evaluated the biochemical contents. Other ejaculates were evaluated macroscopically and microscopically, and then extended in Tris and Na-citrate media to a total concentration of 100 billion cells mL-1. Extended semen was stored at 4oC, and evaluated the motility and viability every 12 h. Frozen semen was made in Tris medium added with 5% of glycerol. The seminal plasma of anoa contained total lipid, Na, Ca and Mg higher than the buffalo, but its total protein, K and Cl were lower. Electrophoresis of seminal plasma using by SDS-PAGE method showed 10 bands of proteins (17-148 kDa). The motility and viability of chilled-extended semen in Tris and Na-citrate media were not significantly different (P > 0.05) during 72 h of evaluation. Extended semen in both of media may applicable for AI program for 24-48 h. Post thawing motility of frozen semen was still low, 26.00 ± 9.62%. Therefore, it is necessary to improve each stages of semen processing, so the motility will increased and resulted high pregnancy in AI program.

Abstract

The aims of study was to compare the glycerol concentration in Tris glucose egg yolk (TGEY)diluents on the quality of deer frozen semen. Semen was collected from 5 Timor deer usingelectroejaculator. Immediately after collection the semen was evaluated macroscopic andmicroscopically. After initial evaluation, the semen was divided into three tubes and extended with Trisegg yolk with three different glycerol concentrations, which were 10% (TGEY10); 12% (TGEY12) and14% (TGEY14). The sperm motility, viability, acrosome intact and membrane intact were evaluated inraw semen, after equilibration and after thawing. The results showed that there were no differences(p>0.05) on the sperm motility, viability as well as sperm acrosome intact. Sperm membrane intact inTGEY10 (52.50±5.89%) and TGEY14 (51.50±4.12 %) were higher (p<0.05) than in TGEY12(49.00±6.58). It was concluded that 10, 12 or 14% glycerol concentration can be used for Timor deersemen cryopreservation.

Abstract

This experiment was conducted to determine the dietary Vitamin E requirement for reproduction of broodstock zebrafish Danio rerio.  Four isonitrogenous (39% crude protein) and isocaloric (3,260 kcal digestible energy/kg diet) practical diets, namely diets A, B, C, and D with different levels of Vitamin E were fed to zebrafish broodstock.  The broodstock were cultivated in aquaria.  Diet A contained low dosage of Vitamin E (5 mg Vitamin E /kg diet), while diets B (62 mg Vitamin E /kg diet), C (125 mg Vitamin E /kg diet), and diet D (187 mg Vitamin E /kg diet), combined respectively with 1% n-3 fatty acids and 2% n-6 fatty acids.  Fish were fed ad satiation for 60 days using these diets.  During feeding period, gonad maturation stages were examined.  The dietary with different level of Vitamin E affected egg size, chemical content, total number of larvae, normal larvae, and survival rate of larvae produced, fecundity, fertilization rate, and hatching rate.  On the other hand, fish fed on experimental diets did not show any significance differences in the gonad somatic index, fecundity, fertilization rate, and hatching rate.  Fish fed on diet D produced the highest fecundity (633.65 ± 71.86 eggs/grams of fish), fertilization rate (92.3 ± 7.7%), and hatching rate (80.31 ± 9.8%).  The total lipid content of eggs were significant, ranging from D (39.7%), C (33.5%), B (32.1%), and A (29.5%).  At a dosage of 1% of dietary n-3 fatty acids and 2% n-6 fatty acids, zebrafish require 187 mg Vitamin E/kg feed in the diet for reproduction.  . Keywords:  vitamin E, reproductive performance, Danio rerio   ABSTRAK Penelitian ini ditujukan untuk mengetahui kebutuhan Vitamin E pada pakan induk ikan zebra (Danio rerio) untuk reproduksi.  Empat pakan perlakuan yang iso-protein (39%) dan iso-kalori (3.260 kcal digestible energy/kg pakan), dinamakan pakan A, B, C, dan pakan D dengan kandungan Vitamin E yang berbeda diberikan kepada induk ikan zebra.  Induk ikan dipelihara pada akuarium.  Pakan A mengandung Vitamin E terendah (5 mg Vitamin E/kg pakan), sedangkan pakan B mengandung Vitamin E 62 mg Vitamin E/kg pakan, pakan C asam mengandung Vitamin E 125 mg /kg pakan, dan pakan D mengandung Vitamin E 187 mg /kg pakan.  Semua pakan perlakuan mempunyai kombinasi asam lemak n-3 berbanding n-6 sebesar 1:2.  Ikan diberi pakan secara ad satiation selama 60 hari pemeliharaan.  Selama masa pemberian pakan, tingkat kematangan gonad diperiksa secara teratur.  Perbedaan kandungan vitamin E dalam pakan mempengaruhi fekunditas, derajat pembuahan telur, serta derajat penetasan telur.  Pakan perlakuan tidak mempengaruhi nilai gonad somatik indeks dan kelangsungan hidup larva umur 3 hari.  Pemberian pakan D menghasilkan fekunditas (633.65 ± 71.86  telur/gram induk), derajat pembuahan telur (92.3 ± 7.7%), serta derajat penetasan telur (80.31 ± 9,8%) terbaik.  Total kandungan lemak pada telur berbeda nyata, yaitu pada pakan D (39.7%), C(33.5%), B(32.1%), dan pakan A(29.5%).  Pada kandungan 1% asam lemak n-3 dan 2% asam lemak n-6, ikan zebra membutuhkan 187 mg Vitamin E/kg pakan untuk reproduksi yang normal.  Kata kunci:  Vitamin E, penampilan reproduksi, Danio rerio
