Background: Sperm cells are susceptible to oxidative stress during cryopreservation. Therefore, an antioxidant is necessary to protect them from damages. Fetal bovine serum (FBS) is one of potent antioxidants for fish sperm cryopreservation. Hence, the aims of this study are to examine the effect of FBS on sperm quality after a short period and to determine its optimum concentration on depik (Rasbora tawarensis). Methods: Depik fish were obtained from the Fish hatchery of Lukup Badak, Aceh Tengah District, Indonesia. Sperms collected from the fish were diluted in Ringer extenders containing FBS concentration of 10% (P1), 20% (P2), 30% (P3), 40% (P4), 50% (P5) and 60% (P6), filled into 2 ml cryotubes and equilibrated prior immersed into liquid nitrogen for 15 days. The parameters observed were sperm motility, consistency, pH, fertilization and hatching rates and DNA fragmentation post-thawing. Result: The ANOVA test indicates that the application of FBS in Ringer had a significant effect on sperm motility, fertilization and hatching rates (P less than 0.05). The highest motility (58.33%) was recorded at FBS 60% and significantly different from those at other concentrations. The laddering analysis showed that applying FBS protected the integrity of depik sperms DNA. It is concluded that the optimum concentration of FBS on depik sperm led to a short-term cryopreservation of 60%.

Cryotolerance of bovine embryos produced in vitro (PIV) can be improved by l-carnitine. The objective of the present study was to determine whether the optimal concentration of l-carnitine is dependent on serum. Bovine embryos were produced in vitro with abattoir-derived oocytes. After fertilization (Day 0), oocytes (n = 2768) were randomly assigned in a 2 × 4 factorial design to culture in SOF-BE1 medium supplemented with or without 5% fetal bovine serum and l-carnitine at concentrations of 0.0, 0.75, 1.5, and 3.03 mM at 38.5°C in a humidified atmosphere of 5% O2, 5% CO2, and 90% N2. The proportion of oocytes that cleaved was assessed on Day 3, and the proportion of oocytes that developed to the blastocyst and advanced blastocyst (expanded, hatching, and hatched) stages was determined on Day 7. Blastocysts and expanded blastocysts (n = 466) were harvested on Day 7 and subjected to controlled-rate freezing following equilibration in 1.5 M ethylene glycol. After thaw, embryos were cultured for 72 h in SOF-BE1 supplemented with 10% (v/v) fetal bovine serum and 50 mM dithiothreitol at 38.5°C in a humidified atmosphere of 5% O2, 5% CO2, and 90% N2. Post-thaw re-expansion and hatching rates were determined at 24, 48, and 72 h. The experiment was replicated 9 times, and data were analysed by logistic regression. There was no interaction between serum and l-carnitine, at any of the concentrations tested, on embryo development or cryotolerance. Cleavage rates were not affected by serum or l-carnitine. Addition of serum during culture increased (P < 0.05) development to the blastocyst (19.7 ± 1.1% v. 25.3 ± 1.4%) and advanced blastocyst (9.1 ± 0.8% v. 12.4 ± 1.2%) stages. While l-carnitine did not affect blastocyst development, advanced blastocyst development was reduced (P < 0.05) for l-carnitine at 3.03 mM (0 mM: 10.9 ± 1.2%, 0.75 mM: 12.2 ± 1.4%, 1.5 mM: 13.5 ± 1.5%, 3.03 mM: 7.0 ± 1.0%). Serum reduced (P < 0.01) re-expansion (78.1 ± 3.4% v. 65.5 ± 3.1%, 81.0 ± 3.0% v. 68.4 ± 2.7%, 78.4 ± 3.4% v. 65.8 ± 3.1%, for 24, 48, and 72 h, respectively) and hatching (52.0 ± 4.0% v. 39.8 ± 3.6%, 61.2 ± 4.1% v. 45.4 ± 3.8%, 61.2 ± 4.1% v. 45.4 ± 3.8%, for 24, 48, and 72 h, respectively) rates at all time points. In contrast, treatment of embryos with l-carnitine during culture increased (P < 0.05) post-thaw re-expansion rates at 24 and 48 h, regardless of concentration (Table 1). In conclusion, post-thaw viability of bovine embryos PIV can be improved by the addition of l-carnitine during culture. Moreover, the beneficial effects of l-carnitine on cryosurvival are not dependent on serum supplementation.

Porcine embryos, derived from in vitro maturation and fertilization, were used to investigate the effects of timing of serum inclusion and PVA replacement in the medium for in vitro culture (IVC) on rates of blastocyst formation and hatching. In Experiment 1, presumptive zygotes at 20 h post-insemination (hpi) or cleaved embryos obtained by culture in porcine zygote medium (PZM-5) containing 3 mg mL−1 polyvinyl alcohol (PVA) at 48 or 96 hpi were further cultured in either PZM-5 containing PVA or PZM-5 where PVA was replaced by 1%, 5%, or 10% fetal bovine serum (FBS) until Day 6 (Day 0 = the day of in vitro insemination). Supplementation with 1% to 10% FBS at 20 and 48 hpi reduced (P < 0.05; by ANOVA and Fisher's PLSD test) blastocyst rates on Days 5 (0% to 1%) and 6 (3% to 6%) compared with PVA supplementation (4% and 22%, respectively). However, addition of 10% FBS at 96 hpi increased (P < 0.05) blastocyst rates (30%) on Day 5 compared with PVA (11%) and 1% FBS (15%); there was no significant difference among treatments in rates of blastocyst formation on Day 6 (24% to 40%). The total number of blastomeres in Day 6 blastocysts did not differ among treatments at any timing of serum supplementation (26.5 to 48.3 cells). In Experiment 2, presumptive zygotes were cultured from 20 to 96 hpi in PVA medium, and the cleaved embryos were later transferred into PZM-5 containing PVA, or 1%, 5%, or 10% FBS for another 4 days. Hatching rates of embryos on Days 7 and 8 were significantly higher (P < 0.05) in PZM-5 where PVA was replaced with 10% FBS (15% and 20%, respectively) than those in PZM-5 containing PVA (1% and 5%, respectively). Moreover, the total cell number in hatching/hatched blastocysts on Day 8 were significantly greater (P < 0.05) in medium containing 10% FBS (135.1 cells) than that in PVA medium (77.0 cells). In Experiment 3, at 130 hpi, blastocysts derived from IVC with PZM-5 containing PVA were transferred into PZM-5 containing PVA, 3 mg mL−1 bovine serum albumin (BSA) or 10% FBS for another 2 days. Hatching rates of blastocysts on Days 6, 7 and 8 were significantly higher (P < 0.05) in PZM-5 where PVA was replaced with 10% FBS (12%, 56%, and 64%, respectively) than those in PZM-5 containing PVA (0%, 12%, and 20%, respectively) and BSA (0%, 12%, and 20%, respectively). Moreover, the total cell number in hatching/hatched blastocysts on Day 8 were significantly greater (P < 0.05) in medium containing 10% FBS (138.7 cells) than that in PVA (71.7 cells) and BSA medium (70.7 cells). The results indicate that the timing of serum inclusion in the culture medium markedly affects porcine embryo development in vitro and that replacement of PVA with FBS in PZM-5 at 96 hpi or later improves the subsequent development of embryos to the hatching/hatched blastocyst stage.

Создание эффективной унифицированной системы дозревания донорских ооцитов обеспечит повышение результативности инновационных клеточных репродуктивных технологий. В исследовании проведен сравнительный мониторинг показателеймейотического созревания ооцитов коров, созревших в различных системах, дополненных структурными компонентами фолликулов (СКФ стенки фолликулов, клетки гранулезы, белки) и фолликулярной жидкостью,а также потенций к развитию из них доимплантационных эмбрионов. Анализу подверглись ооциты, прокультивированные в следующих системах:среда ТС199 с добавлением 10 фетальной бычьей сыворотки (ФБС), 50 мкг/мл эстрадиола, 10 мкг/мл лютеинизирующего гормона (ЛГ), 10 мкг/мл фолликулостимулирующего гормона (ФСГ) среда ТС199 с 10 эстральной сывороткой коров среда ТС199 с 50 жидкости из фолликулов диаметром 9 мм среда ТС199 с добавлением белков фолликулярной жидкости молекулярной массой 65 кДасреда ТС199 с 10 ФБС и 1106 клеток гранулезы среда ТС199 с 10 ФБС и тканью фолликула. В культуральные среды ко всем исследованным группам ооцитов добавляли антибиотики. Использование CКФ обеспечило значительное снижение доли ооцитов с дегенерированным хроматином, что способствовало увеличению уровня доимпланационных эмбрионов на стадии бластоцисты. Так, доля бластоцист, развившихся из ооцитов, созревших в среде со стенками фолликулов,составила43,5. В этой же группе выявлен минимальный уровень дегенерированных зародышей (6,45). Полученные данные предлагается использовать при моделировании систем дозревания ооцитов коров с целью повышения качества яйцеклеток.The creation of an effective unified maturation system of donor oocytes provides an increase in the efficiency of innovative cellular reproductive technologies. The comparative analysis of the meiotic maturation indicators of bovine oocytes, which were matured in different cultural systems modified by follicular structural components (FSC follicular walls, granulosa cells, proteins) and follicular fluid, as well as the potential for preimplantation embryonic development were evaluated in this study. Oocytes matured in following cultural systems: medium TC199 supplemented with 10 fetal bovine serum and 50 g/ml of estradiol, 10 g/ml of luteinizing hormone (LH), 10 g/ml of folliclestimulating hormone (FSH) medium TC199 with 10 estrous cow serum medium TC199 with 50 liquid from follicles with a diameter of 9 mm medium TC199 supplemented with the follicular fluid proteins with molecular weight 65 kDa medium TC199 with 10 fetal bovine serum and 1106 granulosa cells medium TC199 with the addition of 10 fetal bovine serum and follicle tissues were analyzed. Antibiotics were added to cultural media of all experimental groups of oocytes. The usage of FSC ensured the decrease in the proportion of oocytes with degenerated chromatin, which contribute the rise of the level of preimplantation embryos at the blastocyst stage. Thus, the proportion of blastocysts developed from oocytes matured in medium supplemented with follicular walls was 43.5. In the same experimental group, the number of degenerated embryos was 6.45. The obtained data are supposed to be used for modeling the cultural systems of cow oocytes in order to improve the egg quality.

One thousand lots of pooled fetal bovine serum (FBS) were tested for contamination with bovine viral diarrhea virus (BVDV) and/or for contamination with neutralizing antibody against BVDV. Noncytopathic or cytopathic BVDV was isolated from 203 lots of FBS. Analysis of the viral isolates identified 115 type 1 and 65 type 2 BVDV isolates. An additional 23 virus isolates were mixtures of >2 BVDV isolates and were not classified to viral genotype. Further characterization of the type 1 viruses identified 51 subgenotype 1a and 64 subgenotype 1b BVDV isolates. Viral neutralizing antibody was detected in 113 lots of FBS. Differential viral neutralization indicated that type 1 BVDV induced the antibody detected in 48 lots of FBS and type 2 BVDV induced the antibody detected in 16 lots of FBS.
