The present study used the ratio of 80% coconut water and 11 - 20% egg yolk substitution with extract guava ranged from 4 to 9% in order to determine the quality and fertility of Bali cattle storaged at 50C. This study used a complete factorial design with two factors and six treatments. The first factor was coconut water and egg yolk substituted with extract guava extender at different ratio consisted of 6 treatments. They were: (1) T0 (control) = 80% coconut water + 20% egg yolk without extract guava; (2) T1 = 80% coconut water + 16% egg yolk + 4% extract guava; (3) T1 = 80% coconut water + 15% egg yolk + 5% extract guava; (4) T2 = 80% coconut water + 14% egg yolk + 6% extract guava; (5) T3 = 80% coconut water + 13% egg yolk + 7%; and (5) T4 = 80% coconut water + 12% egg yolk + 8% extract guava; and (6) T5 = 80% coconut water + 11% egg yolk + 9% extract guava. The second factor was the length of storage at low temperature which consisted of 3 treatments, including 1 day, 2 days, 3 days, 4 days, 5 days, 6 days and 7 days. The semen used in this study had motility ranged from 50 to 55%. The variables measured in this study were intact plasma membrane (IPM) and intact acrosome hood (ICH). The results showed that the percentage of spermatozoa motility for T1 until the sixth day of storage was 55.51%, T2 until the seventh day of storage was 40.14%, T0 to the fifth day was 41.73%, T3 and T4 until the fourth day was 43.85% and 41.11%, respectively, whereas for T5 only until the third day were 51.00% and T6 until the second day amounted to 48.83%. Viability of Bali cattle spermatozoa in the six treatment groups where egg yolk substituted with extract guava was higher (T1, T2 and T6) compared to T0 from the first day until the fifth day of storage. It can be concluded that substitution of 15% egg yolk with 5% extract guava in 80% coconut water diluents can maintain IPM and ICH spermatozoa of Bali cattle until the sixth day of storaged at 5°C.
The aim of this research was to know the effectiveness of guava filtrate supplementation in coconut water- egg yolk dilution on quality of liquid semen stored at 5oC of Bali cattle. Semen collected from a five year old Bali cattle using artificial vagina. Semen of good quality were kept in six tubes based on treatment then stored at 5oC. Treatments of the research were P0 : coconut water 80% + egg yolk 20% without guava filtrate; P1 : coconut water 80% + egg yolk 20% + 0.8% guava filtrate; P2 : coconut water 80% + egg yolk 20% + 0.9% guava filtrate; P3 : coconut water 80% + egg yolk 20% + 1.0 % guava filtrate; P4 : coconut water 80% + egg yolk 20% + 1.1 % guava filtrate and P5 : coconut water 80% + egg yolk 20% + 1.2 % guava filtrate. Each treatment was replicated 8 times making 48 experimental units. Results of the study showed that percentage mean of motility, viability, MPU, and TAU of spermatozoa after three days storage for P0 were : 42.20%, 41.85%, 39.08% and 40.90%; P1 : 50.40%, 53.89%, 52.99% and 54.67%; P2 : 54.67%, 56.97%, 54.51% and 54.36%; P3 : 17.00%, 29.96%, 29.64% and 29.64%; P4 : 23.38%, 24.64%, 21.06% and 24.45%Jurnal Veteriner Maret 2019 Vol. 20 No. 1 : 20 -29 pISSN: 1411-8327; eISSN: 2477-5665 DOI: 10.19087/jveteriner.2019.20.1.20 Terakreditasi Nasional, Dirjen Penguatan Riset dan Pengembangan, online pada http://ojs.unud.ac.id/index.php/jvet Kemenristek Dikti RI S.K. No. 36a/E/KPT/201621PENDAHULUAN Salah satu solusi yang dapat digunakan untuk pengembangan program Inseminasi buatan (IB) secara cepat dan mudah pada sapi bali adalah penggunaan semen cair. Penggunaan semen cair dapat meningkatkan kinerja IB pada sapi bali di Nusa Tenggara Timur (NTT). Keunggulan lain semen cair dapat diproduksi menggunakan bahan pengencer herbal berbasis bahan lokal dan peralatan yang sederhana serta mudah diperoleh dan tidak tergantung dengan persediaan nitrogen cair. Hasil akhir dari metabolisme spermatozoa adalah terbentuknya radikal bebas berupa derivat oksigen di antaranya adalah single1 oksigen (1O2), tripel1 oksigen (3O2), superokside anion (O2-), hidroksil radikal (OH) dan nitrit oxide (NO-) yang semuanya disebut radical oksigen species (ROS). Single1 oksigen dapat merusak ikatan rangkap pada asam lemak sehingga dapat menyebabkan kerusakan Deoxyribo Nuclead Acid (DNA) dan protein. Single1 oksigen bila bereaksi dengan asam amino histidin akan membentuk enzim yang dapat menyebabkan denaturasi protein. Kerusakan spermatozoa pada penyimpanan suhu 5%C akibat radikal bebas dan cold shock inilah merupakan penyebab utama disfungsi semen (Sharma et al., 2000). Oksidasi fosforilasi yang terganggu menyebabkan peningkatan radikal bebas dalam semen. Kadar radikal bebas yang terganggu menyebabkan peningkatan radikal bebas dalam semen. Kadar radikal bebas yang tinggi dalam sel dapat mengoksidasi lipid, protein dan DNA. Lipid membran plasma semen memiliki fosfolipid dengan kadar yang tinggi menyebabkan semen rentan terhadap radikal bebas (Sanoeka dan Kurpisz, 2004). Antioksidan bertindak mengikat asam lemak tak jenuh dan mencegah terjadinyareaksi berantai. Pada proses penyimpanan semen akan terjadi kerusakan membran plasma spermatozoa akibat terbentuknya perioksidasi lipid. Antioksidan-pemutus rantai seperti yang terkandung dalam jambu biji dapat menghambat perioksidasi lipid dalam membran melalui radical peroxyl (RO) dan alkoxyl (ROO) pengurai. Pengunaan jambu biji yang difilter dalam pengencer air kelapa kuning telur dapat menjaga kualitas spermatozoa (motilitas, keutuhan akrosom, viabilitas dan morfologi spermatozoa) semen cair sapi bali selama penyimpanan pada suhu 5%C. Dosis jambu biji yang difilter yang terbaik dalam pengencer air kelapa kuning telur, akan terbaik pula dalam mempertahankan kualitas spermatozoa sampai tujuan IB. Adapun tujuan penelitian ini adalah menguji berbagai level pemberian filtrat jambu biji (FJB) dalam pengencer air kelapa kuning telur terhadap motilitas, viabilitas, membran plasma utuh (MPU) dan tudung akrosom utuh (TAU) spermatozoa sapi bali yang disimpan pada suhu 5%C.METODE PENELITIAN Penelitian ini telah dilakukan di Laboratorium Reproduksi milik Yayasan Wiliams dan Laura yang berlokasi di Tilong, Desa Oelnasi, Kec. Kupang Tengah, Kab. Kupang, Nusa Tenggara Timur, dan berlangsung selama delapan bulan. Materi yang digunakan dalam penelitian ini adalah semen sapi bali yang ditampung dari satu ekor sapi bali jantan berumur lima tahun milik Yayasan Williams dan Laura yang telah dilatih, memiliki performans yang baik, dan organ reproduksi normal. Pakan yang diberikan adalah hijauan berupa rumput dan legum dan pemberian konsentrat secukupnya (dedak padi dan jagung giling).and P5 : 9%, 21.25%, 17.56% and 19.30%. Result of statistical analysis showed that there were a significant effect (P<0.05) between treatment on motility, viability, MPU and TAU of spermatozoa of Bali cattle till the third day of storage. It can be concluded that the supplementation of guava filtrate 0.9% in dilution of coconut water 80% - egg yolk 20% had been able to maintain motility, viability, MPU and TAU of spermatozoa of Bali cattle till the third day of storage at 5oC.
The purpose of this study was to determine the effect of giving pituitary extract (EH) and probiotics ABG-O on piglets crossing to increase weaning weight, linear size of body and blood metabolites. The research material was a crossbred of landrace and duroc aged 2 weeks, as many as 24 birds. The experimental design was a completely randomized design with three treatments and eight replications. The three treatments are P0 (control), P1 (EH injection 1 mL), and P2 (injection EH 1 mL + probiotic ABG-O 2 mL). EH injections are carried out every 5 days and administration of probiotics is given orally using spoit every day until the piglets are weaned. The parameters observed were weight gain, linear size of body and blood metabolites. This data was analyzed by ANOVA and continued with Duncan test. The results of this study indicate that the average daily weight gain of crossbred piglets in treatments P0, P1, and P2 are 0.11; 0.13; 016 kg, body length (0.40; 0.45; 0.44 cm), chest circumference (0.29; 0.27; 0,30 cm), and shoulder height (0.25; 0.24; 0.25 cm). Blood glucose levels (117.31; 112.85; 117.25) and total plasma protein (4.60; 4.90; 4.80). The results of the statistical analysis showed that the EH and ABG probiotic treatments affected the UN (P<0.05) but did not affect (P> 0.05) the size of the linear body and blood metabolites. It can be concluded that the administration of pituitary extracts and ABG probiotics can increase the weaning weight of crossing piglets but does not affect the linear size of the body and blood metabolites.

The quality of porcine semen deteriorates very rapidly during the semen preservation process. The aim of this study is to find alternative diluents for Duroc semen preservation by changing different semen diluents. Two Duroc pigs, ± 3 years old, were trained twice weekly for semen collection. Immediately after collection, sperm were examined macroscopically and microscopically. Semen with sperm motility ≥ 70%, sperm concentration ≥200 x 106 cells/ml, and abnormality ≤20%) was diluted with six diluents, namely: Beltsville Thawing Solution® (BTS), Durasperm, Citrate Egg Yolk (CEY), Tris Egg Yolk (TEY), CEY + Olive Oil (CEYO) and TEY + Olive Oil (TEYO) in the ratio of one part semen and four parts diluent. The liquid sperm was stored at 18-20 oC and examined every eight hours for 80 hours. The result shows that sperm motility, viability and plasma membrane integrity of Duroc semen with CEYO and TEYO are comparable to BTS. No significant difference was found in sperm abnormalities. The results suggest that citrate egg yolk and Tris egg yolk in combination with olive oil are suitable as alternative diluents for the preservation of porcine sperm. Further studies are needed to determine the most suitable olive oil concentration for the preservation of porcine sperm of different breeds.
This study aimed to examine the quality of frozen sperm of duroc boar in modified Tris diluent with different equilibration time. Semen was collected from two duroc males and evaluated macroscopically and microscopically. Semen with motility 75%, concentration 200x106 cell/mL and abnormality <20% was diluted in Tris modified diluent, then held for two hours at room temperature (27-28ºC). The semen that has been in the holding time is then centrifuged at 2000 rpm for 15 minutes. The pellet from centrifuge were diluted again with modified Tris diluent + 3% glycerol. The diluted semen was packed in 0,50 mL mini straws and equilibrated according to the treatment equilibration time, namely P1: 1 hour equilibration time, P2: 2 hour equilibration time, P3: 3 hour equilibration time. After equilibration , it was frozen over liquid nitrogen vapor (-110ºC) at a distance of 5 cm for 10 minutes, then stored in liquid nitrogen (-196ºC) and left for 24 hours. Then thawing with warm water at 37ºC for 30 seconds in a water bath. The result showed that motility, viability, abnormality, intact plasma membrane and recovery rate were significantly higher (P<0,05) at two hour equilibration , namely 23.12%, 45.44%, 4.65%, 50,15%, 33.03% respectively compared to one and two hour equilibration time, namely 20%, 42.17%, 8.19%, 42.67%, 28.57% and 16,87%, 36.39%, 7.64%, 37.73%, 24.99% respectively. This study conclude that the equilibration time of two hours resulted in higher quality of frozen sperm of duroc boar than one and three hours.
The purpose of this study was to determine the effect of adding onion extract (OE) to Tris-egg yolk (T-EY) diluent on the quality of bali bulls spermatozoa. The semen of three bali bulls aged 3-4 years were collected twice a week using the artificial vaginal method. Semen with good quality, motility 79%, viability 84.63%, abnormality 2.93% diluted with T-EY diluent with the addition of OE: T0: 0%; T1 1%; T2: 2%; T3: 3%; T4: 4%; and T5: 5%. The diluted semen was preserved in a refrigerator at 3-5 °C and evaluated for the quality of the spermatozoa every 24 hours. The results showed that the addition of OE in T-EY diluent had a positive effect on the quality of bali bulls spermatozoa. The addition 3% of OE (T3) in T-EY diluent resulted in higher spermatozoa quality (P <0.05) than the other treatments, namely motility 42.01%, viability 48.74%, and abnormalities 4.13% on the sixth day of preservation. It was concluded that the addition of onion extract in Tris - egg yolk diluents could improve the quality of bali bulls spermatozoa, with the best level of onion extract being 3%.
An experiment was carried out to recognize the effect of long equilibration time on the quality of spermatozoa and to obtain optimal equilibration time in the process cryopreservation of landrace pig semen. Semen was obtained from a landrace boar aged 2-3 years using glove hand method. The semen was than evaluated macroscopically and microscopically, good quality semen was diluted in a basic diluent, than kept for two hours at a temperature of 27-28oC. The semen were then centrifuged at 2000 rpm for 15 minutes, the supernatant was discarced and the pellets was re-diluted into basic diluent with a ratio of 1:1. Then, semen was diluted in treatment diluent with modified durasperm + 6% lactose + 4% glycerol with a concentration of 500 x 106/0.5 mL. Furthermore, the semen was packaged in 0.5 ml straws, then equilibrated at a temperature of 3-5oC appropriate to treatment, with 1 hour equilibration (T1), 2 hours equilibration (T2) and 3 hours equilibration (T3). After equilibration, the straws was frozen horizontally 5 cm above the liquid N2 vapor for 10 minutes at a temperature of ± -110oC and then stored in a liquid N2 container (-196oC). To test frozen semen, it was done by stored frozen semen at 37oC for 30 seconds. The results showed that the highest quality of spermatozoa (P <0.05) was found in T2 and T3 when compared to T1 (P> 0.05), with the motility value was T2: 28.13 ± 2.39%; T3: 25.00 ± 4.08%; and T1 18,15±3,23%. It can be concluded that 2 hours and 3 hours equilibration time was able to maintain the quality of frozen semen landrace boars and the statistically was not significant.
