“…The present observations were in close proximity with the reports of previous researchers (Saikia et al 2016). However, Lalrintluanga et al (2016) reported lower mean percentage of HOST-reacted sperm than obtained in the present study. The mean percentage of HOST-reacted spermatozoa decreased significantly (P<0.05) with the increase in duration of preservation in all the extenders which could be due to the progressive decrease in biochemical activity of spermatozoa with the increase in preservation period.…”

The present study was designed to compare the efficacy of 3 different extenders for preservation of boar semen at 15°C. Ejaculates (32) were evaluated and extended (1:4) in TRIXcell+, Modena and GEPS extenders and kept for 4 h of holding at 22°C. The samples were preserved in a BOD incubator at 15°C up to 168 h and evaluated for sperm motility, intact acrosome and HOST-reacted sperm at 0, 72, 96, 120, 144 and 168 h of preservation. The mean percentage of sperm motility, intact acrosome and HOST-reacted sperm was significantly higher in TRIXcell+ extender than Modena and GEPS at different hours of preservation. Out of the 3 extenders studied, TRIXcell+ was found to be the best followed by Modena and GEPS extenders respectively based on sperm motility, intact acrosome and HOST.

“…The control group had the lowest acrosome integrity among all the groups (P < 0.05). Longterm storage increases the proportion of prematurely capacitated and acrosome reacted sperm (Kumaresan et al, 2009;Huo et al, 2002;Lalrintluanga et al, 2014). In this study, application of -0.04 MPa did not reduce the percentage of viable sperm with an unstable plasma membrane, but did significantly increase the proportion of live sperm with an intact acrosome.…”

The present study was aimed to investigate the effects of negative pressure applied before storage on the quality and fertilization ability of boar semen. Boar semen samples were collected and pooled, and diluted with Modena solution containing 0.4% (w/v) of bovine serum albumin. Negative pressure was applied for 2–5 min using a vacuum pump with a barometer. The pressure applied were 0 (Control), -0.02 MPa (P200), -0.04 MPa (P400), and -0.08 MPa (P800). The sperm motility, acrosome integrity and sperm fertilizing ability were evaluated. Application of –0.04 MPa improved the sperm motility, acrosome integrity and fertilizing ability, compared with the other groups. The sperm motility and acrosome integrity decreased with increasing storage time in vitro. After 5 days, the sperm motility and acrosome integrity of the P400 group were all higher than those of the other groups (P less than 0.05). The cleavage rate (64.5% ± 2.4%) and blastocyst development rate (33.9% ± 2.8%) for semen stored for 7 days were similar to those of fresh semen. In conclusion, application of –0.04 MPa before liquid storage at 17°C can improve the quality and fertilization ability of boar semen.

“…During storage at 15-18°C, boar spermatozoa undergo several changes, including decreased motility (Lalrintluanga et al, 2014), an increase in sperm with acrosome damage (Leahy et al, 2011), and a decrease in ATP concentration and mitochondrial activity (Gogol et al, 2009). Many studies have demonstrated that preservation of boar spermatozoa for long periods requires a decrease in their metabolic activity, which is achieved by dilution in an appropriate medium and lowering the temperature to 15-17°C (Johnson et al, 2000).…”

This study aimed to investigate the influence of negative pressure on boar semen quality during liquid preservation at 17°C. Semen samples from ten large white boars were collected and pooled, divided into four equal parts, and diluted with Modena containing 0.4% (w/v) of bovine serum albumin. The semen samples were placed in a closed container with valve, and a negative pressure was applied for 2-5 minutes using a vacuum pump with a barometer. The control group had no treatment, the P200 group was treated at 200 mbar, the P400 group at 400 mbar, and the P800 group at 800 mbar. During liquid preservation, sperm motility, total antioxidant capacity, and semen H 2 O 2 content were analyzed every 24 h. The effective survival time of boar semen during preservation was evaluated. The results indicated that a suitable negative pressure decreased the effects on reactive oxygen species on boar sperm quality during liquid preservation compared with the control group. Among all the groups, the 400 mbar negative pressure group had the highest sperm motility, total antioxidant capacity, and the percentage of spermatozoa with high mitochondrial membrane potential. The P400 group also had semen H 2 O 2 content than the other groups. A suitable negative pressure improves sperm quality by reducing oxidative stress and the respiratory metabolism of sperm, and the optimum negative pressure is 400 mbar.
