Semen was collected from four rams, using artificial vagina and viability%, motility% and plasma membrane integrity% were measured. Fresh ejaculates (n = 32) were separated by modified swim-up separation using modified human tubal fluid medium. Four fractions of supernatant were collected at 15-minute intervals. The mean volume, mass activity, concentration, motility%, viability%, normal morphology and membrane integrity% (HOST +ve) of fresh semen were 1.0 ± 0.14, 4.1 ± 0.1 × 109 spermatozoa/ml, 85.0 ± 1.3, 89.4 ± 1.0, 85.5 ± 0.7, 84.7 ± 0.5 respectively. There was no significant (P>0.05) difference in fresh semen quality parameters between rams. The motility%, viability% and HOST +ve % of first, second, third and fourth fractions were 53.4 ± 0.5, 68.2 ± 0.3, 74.8 ± 0.3 and 65.5 ± 0.4; 55.5 ± 0.4, 66.2 ± 0.4, 74.5 ± 0.3 and 73.6 ± 0.3 and 66.7 ± 0.5, 66.8 ± 0.5, 65.2 ± 0.4 and 74.7 ± 0.5 respectively. The motility%, viability% and membrane integrity% of separated semen samples differed significantly (P<0.05) between four fractions. The mean motility% and viability% were significantly higher (P<0.05) in third fraction (74.8 ± 0.3%), whereas the mean HOST +ve% was significantly higher (P<0.05) in fourth fraction (74.7 ± 0.5). All quality parameters of separated spermatozoa were significantly (P<0.05) lower than that of fresh semen. The pregnancy rates were higher with fresh semen (71%) in comparison to that of separated sample (57%).Bangl. vet. 2016. Vol. 33, No. 2, 62-70

The aim of this study was to address the question whether changes in boar semen quality after short-term storage could be predicted on the basis of standard semen parameters and TNF-α level determined on the day of semen collection under commercial conditions. Progressive motility showed the highest positive correlation with morphology on day 0 of collection, and progressive motility on day 3 (P < 0.05) showed a negative correlation with acrosome abnormalities (P < 0.05). According to the area under receiver operating characteristics (ROC) curves (AUCs), progressive motility could also be used in predicting semen quality after 3 days of storage (AUC > 0.5; P < 0.05). TNF-α in seminal plasma is the only parameter measured on day 0 to show a significant correlation with the percentage of viable spermatozoa after 3 days of semen storage (r = 0.495, P < 0.05). ROC analysis shows that TNF-α level is helpful in discriminating viability outcome after semen storage (AUC = 0.94, P < 0.001). We can predict with 92.35% certainty that fresh semen samples with more than 150 pg/ml of TNF-α in the seminal plasma will retain more than 85% of viable spermatozoa after 3 days of storage. Thus, TNF-α can contribute to predicting the quality of short-term stored semen.

Stallions affected by seminal vesiculitis present history of infertility or subfertility, ejaculatory disturbance, spread of sexually transmitted pathogens, and changes in semen characteristics, leading to reduced semen quality and longevity. The aim of this study was to evaluate the semen quality of stallions with seminal vesiculitis before and after local treatment. Five stallions with a mean age of 12.4 years diagnosed with seminal vesiculitis were used. The identification of the microorganism involved in the pathogenesis of seminal vesiculitis of each animal was performed by bacterial culture of the seminal vesicles flush with Ringer Lactate solution, performed in duplicate at 1-week intervals. After identification of bacteria was performed, there was susceptibility testing to antibiotic (antibiogram) and the appropriate antibiotic was chosen. The local treatment was performed by endoscopy for 10 consecutive days, and this consisted of flushing with Ringer Lactate solution, followed by infusion of the antibiotic selected. The semen analyses were performed before starting the local treatment for seminal vesiculitis (M0), after a week (M1), and after a month (M2) of therapy. Sperm kinetics were performed by computerized method – CASA for the following parameters: percentage of sperm with total motility, progressive motility, and rapid sperm. Analysis of plasma membrane integrity was performed by epi-fluorescence microscopy, using the combination of fluorescent probes carboxyfluorescein diacetate and propidium iodide. Percentage of leukocytes was assessed through evaluation in light optical microscopy of semen smears stained with DiffQuick. The content of nitric oxide (NO) was determined by colourimetric Griess reaction by a spectrophotometer through the concentrations of nitrate (NO3–) and nitrite (NO2–). To perform the count of colony forming units per millilitre (CFU mL–1), an aliquot of 0.1 mL of semen was diluted in 9.9 mL of saline. A 0.1-mL aliquot of this sample was plated on Mueller-Hinton agar. The seeded plates were incubated, and the bacterial colonies were counted after 24 h. According to the performed dilution, total colonies identified corresponds to ×10 000 CFU mL–1. The data were analysed by two-way ANOVA followed by Tukey's test (P < 0.05). The values (mean ± standard error) of seminal parameters on M0, M1, and M2 were the following, respectively: sperm kinetics (total motility: 46.5 ± 5.13a; 75.1 ± 3.42b; 42.8 ± 5.28a; progressive motility: 19.3 ± 3.86a; 33.4 ± 2.39b; 16.5 ± 2.40a; rapid sperm: 22.2 ± 1.82a; 52.2 ± 5.65b; 22.1 ± 2.62a); plasma membrane integrity (47.5 ± 4.65a; 62.9 ± 5.41b; 39.1 ± 4.32a); percentage of leukocytes (35.2 ± 2.36a; 15.1 ± 2.55b; 36.1 ± 4.04a); CFU (119 980 × 103 ± 19 528.0 × 103a; 5375 × 103 ± 2453.7 × 103b; 65 850 × 103 ± 19 701.0 × 103ab) on fresh semen; and NO content (0.645 ± 0.172a, 0.117 ± 0.023b, 0.364 ± 0.110ab) on seminal plasma. The results demonstrate that local treatment after a week leads to an improvement in sperm quality; however, this was not maintained after 1 month of therapy, since the seminal parameters at this time are similar to pretreatment, which can be justified by recurrent disease.

Young Boars

Serbia is one of the countries with the continuous import of breeding sows and boars. Boars are usually imported at the age of 4 to 6 months, in the period when the quality of the breeding males cannot be determined due to sexual immaturity (prepubertal and pubertal age). In this paper, the method and results of semen quality control in 40 imported young boars are described, and also the method of documenting the cause for action claim. In the case of suspicious semen quality it is necesseary to perform at least 3 consecutive controls in one month intervals in order to establish a final estimation of quality and usability of semen. Of 40 imported boars, 4 boars (10%) were subject of complaint due to: azoospermia (1 boar), absence or reduction of total and progressive motility, present sperm agglutination (2 boars), and increased number of pathological forms of spermatozoa (78%, 1 boar). Increased proportion of sperm with unstable chromatin structure (SCSA test - 33.2% and 37.1%) was established in two boars. To initiate the complaint it is necessary to have a sales contract that provides possibility for the reclamation, recognized methods of semen quality control and trustful business relationship between all interested parties.

The study was carried out to observe the effects of preservation time on the quality of frozen semen of indigenous rams. Semen was collected using AV once a week from 4 rams. Tris based with 10% egg yolk and 7% glycerol extender was used to extend and freezing the semen. Fresh semen was evaluated for volume, density, mass motility and concentration, and mean values were observed as 0.8±0.2ml, 3.0±0.3, 3.2±0.7, 3.9±0.7×109/ml, respectively. Significant difference (p<0.05) was found for all the parameters among the rams. Mean values of motility, viability and normal morphology percentages were 83.3±4.3%, 88.2±4.4%, 84.2±3.5% in fresh semen while those of chilled semen at 40C were 74.7±2.3, 78.8±4.9 and 79.2±2.9%, respectively. For all the parameters, significant (p<0.05) difference was found among the rams. Frozen sperm motility was observed after thawing at 39-400C for 14-15 seconds. The mean motility, viability and normal morphology percentages after freezing for 24hrs, 7, 15 and 30 days of duration were 39.8±3.1, 41.1±4.3, 40.1±4.1 and 39.4±2.9%; 44.5±2.5, 45.3±2.8, 44.6±2.8 and 43.9±2.8%; 71.0±2.0, 71.7±1.5, 70.7±1.7 and 70.3±1.8%, respectively and values did not decrease significantly (p>0.05) with the increasing time of preservation. Non significantly decrease of the semen quality with advance of preservation time indicates the suitability of the protocol used for freezing of indigenous ram semen in Bangladesh.DOI: http://dx.doi.org/10.3329/bjas.v44i1.23113            Bang.

Background: Bio-acoustic features of animal’s voice can provide meaningful information about their biological and physical characteristics. The present study was conducted to get indicators of age from voice analysis and explore the relationship between voice features and seminal parameters in Sahiwal bulls. Methods: Voice samples were collected from healthy bulls (n=20), maintained at ICAR-NDRI, Karnal. Bulls were classified into two groups i.e. young bulls and adult bulls. The voice signals were analyzed by Adobe Premium software and acoustic features were extracted by using PRAAT software. Result: The mean of acoustic features viz. call duration (sec), mean intensity (dB), total energy (P2S), amplitude (P), pitch (Hz), unvoiced frame (%), jitter (%), bandwidth (Hz) mean N/H ratio (%) have been found significantly different while mean H/N ratio (dB), shimmer (%) and pulses were not found statistically (P greater than 0.05) different between adult and young bulls. The seminal parameters viz mass activity (0-5 scale), individual progressive motility (%), live sperm count (%) and total sperm abnormality (%) were found significantly different between adult and young bulls. No significant association between voice features and semen quality of bulls was observed. Hence, voice signals of male might provide some clues about their age but for semen quality, there is further need to explore the interesting relationship between voice features and fertility of breeding bulls.

This research aimed to determine the effect of spermatozoa X and Y separation using swim-up method on the quality of etawah crossbreed goat’s spermatozoa. This research used 6 male etawah crossbreed goats aged between 18-24 months, which were collected the semen once a week using electroejaculator. Immediately after semen collection, the quality of semen was examined, and then grouped into three treatment groups. Group 1 was control group (P0) refers to the semen was not separated by swim-up method. Group 2 (P1) was the semen separated by the swim-up method for 5 minutes. Group 3 (P2) was the semen separated by swim-up method for 10 minutes. Each treatment was repeated six times. Parameters for semen quality examined were the percentage of spermatozoa motility, live spermatozoa, and abnormal spermatozoa. Data were analyzed by analysis of variance (ANOVA) one way pattern, followed by Duncan's multiple test. The results showed that the mean ± SD percentage of sperm motility on each treatment groups (P0; P1; P2) was 81.33±3.44, 89.67±3.21, and 90.00±3.10 %, respectively. The percentage of live spermatozoa on each group was 86.50 ± 2.07, 92.33 ± 2.08, and 91.83 ± 1.72%, respectively. The percentage of abnormal spermatozoa on each group was 13.00±2.53, 7.33±2.52, and 7.67±2.16%, respectively. Results of this research showed that the percentages of motility, live spermatozoa, and abnormal spermatozoa after separation by swim-up method were significantly different (P0.05) compared to without separation. It can be concluded that the separation of spermatozoa using swim-up method can improve significantly (P0.05) the percentage of live and motility of spermatozoa and decrease the percentage of abnormal spermatozoa of etawah crossbreed goats.Key words: Etawah crossbreed, spermatozoa quality, swim-up method

Abstract Improvements in the post-thaw quality of frozen semen could allow increased utilization of this technology in the swine industry. The objective of this study was to investigate the effects of natural honey inclusion in semen extender and freezing media on motility, mobility, and morphology of cryopreserved boar sperm. Ejaculates from 6 terminal cross-bred boars were collected using the gloved-hand technique for 3 weeks and used in a 2 x 3 factorial study design. Following collection, semen samples were incubated overnight in dilution extender with and without natural honey (D0: Androhep Plus; D1: Androhep Plus + 0.25% honey). The following day, the semen samples were cooled to 4 C in LEY cooling extender then frozen in freezing media containing 93% cooling extender + 6% glycerol + 1% Equex-STM Paste (F1), or freezing media with natural honey replacing 50% of the glycerol (F2) or 50% of the Equex-STM paste (F3). Semen samples were frozen using a controlled-rate freezer and stored in liquid nitrogen. Two straws per treatment for each boar were thawed and semen quality assessed. The inclusion of natural honey in dilution extender had no effect on post-thaw motility (P=0.733), progressive motility (P=0.562), or other mobility parameters (0.995≤P≥0.081). However, D1 had a higher percentage of normal acrosomes (P=0.001) and morphologically normal cells (P&lt; 0.001) resulting from lower tail abnormalities compared to D0 (P=0.006). Post-thaw motility (P&lt; 0.001) and progressive motility (P&lt; 0.001) were increased in F3 compared to both F2 and F1. F1 had reduced normal acrosomes (P=0.009) and morphologically normal cells (P&lt; 0.001) resulting from higher tail abnormalities (P&lt; 0.001). In conclusion, the inclusion of natural honey, at 0.25%, in dilution extender helps maintain normal sperm and acrosome morphology, and replacing 50% Equex-STM Paste with honey in freezing extender improves post-thaw sperm motility and progressive motility of frozen-thawed boar semen.
