The aim of the work was to examine the effect of modified TALP medium (TALP/Pp, Animal Pharma B.V., Hengelo, The Netherlands)—used in the sperm sexing procedure—on bull sperm membrane status. The TALP was modified by replacement of bovine serum albumin (BSA) with a mixture of several plant proteins and soya lecithin (Pp). The Pp component was prepared using a high pressure homogenization process. The TALP/Pp had the same pH and osmotic pressure as the original TALP medium (TALP/BSA). The work was divided into 2 parts: (1) Nine ejaculates collected from 2 bulls (Holstein and Polish Red) were used. Immediately after collection, each ejaculate was split into 2 parts and diluted (1:2) with TALP/BSA or TALP/Pp. The sperm membrane status was examined after 3 days of storage at 15�C. (2) Fifteen ejaculates collected from 5 bulls (Holstein, Polish Red, and Simmental) were used. Each ejaculate was split into 2 parts: the first part was diluted with TALP/BSA, stained, incubated, and sexed according to the XY Inc. bull semen sexing procedure; the second part was diluted, stained, incubated, and collected after sexing into TALP/Pp with no egg yolk addition. In both groups no red food due was used to identify and exclude the dead spermatozoa from the sorted fractions. The sperm sexing procedure was performed with an SX MoFlo high-speed sorter at a speed of 3000–4000 cells/s. After collecting about 10 million spermatozoa, both fractions, X andY, were mixed, centrifuged at 700g for 15 min to concentrate the spermatozoa (20 million mL–1), and the sperm membranes examined. For sperm membrane examination, 'live/dead' samples were stained with SYBR-14/propidium iodide fluorochromes and analyzed by flow cytometry. The data from 20 000 spermatozoa were collected for each sample. The percentage of membrane-intact ('live') spermatozoa was taken for statistical analysis. The mean percentage of live spermatozoa stored for 3 days in TALP/BSA v. TALP/Pp was 25.7% (SD = 7.48) v. 28.58% (SD = 7.04), respectively (P < 0.01). The mean percentage of live spermatozoa in samples of sexed semen was 33.57% (SD = 18.97) for TALP/BSA and 38.51% (SD = 20.22) for TALP/Pp (P < 0.01). It can be concluded that Pp should be considered as a replacement for BSA in the TALP medium used for bull sperm sexing because (1) it results in significantly higher numbers of live spermatozoa after storage and/or sexing; (2) it eliminates a possible source of transmissible diseases (such as bovine spongiform encephalopathy); and (3) it decreases the total cost of the basic media used for the bull sperm sexing procedure.

Aim: The aim of this study was to investigate the effects of different concentration of butylated hydroxytoluene (BHT) on sperm membrane surface protein "P25b" from cryopreserved bull semen in either lecithin based Bioxcell® (BX) or two egg-yolk based extenders, tris-egg yolk (TEY), and citrate-egg yolk (CEY). Materials and Methods: Forty-five semen samples, 15 each were extended with either BX, TEY, or CEY extender which contained different concentrations (0.0 - control, 0.5, 1.0, 1.5, 2.0, and 3.0 mM/mL) of BHT. The extended semen samples were frozen at a concentration of 20×106/mL in 0.25 mL straws and stored in liquid nitrogen for 2 weeks. The frozen samples were thereafter thawed, proteins extracted and analyzed for quantities of protein P25b through direct sodium dodecyl sulfate-polyacrylamide gel electrophoresis gel densitometry. Peptides were confirmed by Western blotting (WB). Results: Results showed that supplementation of BHT improved (p<0.05) quantity of protein P25b at concentrations of 0.5 mM/mL for BX and at 1.0 mM/mL for TEY and CE when compared with the controls and other treatments. Conclusion: BHT supplementation at 0.5 in BX and 1.0 mM/mL in TEY and CEY has protected bull sperm fertility marker protein P25b in frozen-thawed bull sperm.

Flow citometry cell sorting has been proven successfully to separate X and Y sperm; however, the technology is still too stressfull for the viability of the sorted semen. The objective of this study was to evaluate nonsexed and sexed frozen sperm motility characteristics using a CASA technology. Ejaculates from 4 different bulls (3 Holstein and 1 Angus) were collected, and processed as split non-sexed and sexed semen samples using Tris egg yolk extenders. X and Y sperm were separated using a high-speed sorter (SX Moflo). Cryopreservation was done at the same time under appropiate conditions using a programmed cryochamber. Thawing procedure was done at 37°C for 30s and a sample of each straw was placed in the evaluation chamber. The experiment was repeated twice and two chambers with 30 observations each were analyzed each time. Mean and standard deviation of each characteristic were calculated, compared and analyzed statistically. The sperm concentration was determined by means of a burker counting chamber. Sperm quality was determined at 0h after thawing, and later at 1h, 2h and 3h after incubation in a glass tube at 30°C. The following sperm motility parameters were determined with the Hamilton Thorne (HTM-ceros 12.1) on at least 1000 spermatozoa: velocity average path (VAP), velocity straight line (VSL), amplitude lateral head (ALH), beat cross frequency (BCF), straightness (STR), linearity (LIN), and percentage of progressively motile spermatozoa (PMS). Linearity of nonsexed spermatozoa was 53±3.5, 47±0.8, 43±7.8 and 42±4.5 for the 0h and the 3 test incubation times and 49.5±3.7, 51.2±3.7, 43.3±7.8 and 44.5±7.6, respectively, for sexed semen. There were no significant differences (P&gt;0.05) in the progressive velocity, track speed and linearity between sexed and nonsexed semen. The percentage of static cells was 33%, 30%, 47% and 50% for the 0h and the 3 test incubation periods; however, the percentage of static cells for the sexed semen was 53%, 71%, 77% and 82%, respectively. Results from the analysis indicate a significant increase (P&lt;0.01) in the number and the percentage of static cells with time. The lateral amplitude of sperm motility for nonsexed semen was 5.9±0.5, 6.8±0.8, 6.0±0.4 and 5.1±0.7, and for sexed semen 6.6±0.7, 6.8±0.4, 6.4±0.4 and 5.5±1.7, respectively. The percentage of progressively motile sperm was significantly different at 0 time 49.7±4.9 and 23.1±4.9 for nonsexed and sexed semen respectively. After 3 hours of incubation the percentage of progressively motile sperm was 38.7±10.2 and 3.7±3.2 for nonsexed and sexed semen, respectively. In conclusion, sexed frozen semen seems to have characteristics similar to those of normal nonsexed semen. However, a significant decrease in the percentage of progressively motile cells could affect pregnancy rates. More research needs to be done to detect differences between bulls and cryoprotectans.Research supported by Centro Genetico Bovino de EOLIA sa Argentina.

Flow cytometry is the only reliable and relatively fast method allowing separation of live X and Y spermatozoa for sex regulation. Many thousands of animals of different mammalian species have been born after insemination with sexed semen during the past 20 years. Nevertheless, the question is still open: does the bull sperm sexing technology affect chromatin structure? A case of serious chromatin damage after sexing stallion semen was reported previously (Bochenek et al. 2006 Havemeyer Foundation Monograph Series No. 18, 13 –14). The aim of this work was to examine the effect of the sexing procedure and different UV laser powers on bull sperm chromatin structure. The ejaculates of 28 bulls (one ejaculate/bull) were used in the study. Each ejaculate was divided into 5 groups: (1) control, unprocessed; (2) sorted strictly according to XY Inc. protocol (Schenk et al. 1999 Theriogenology 52, 1375 –1391); (3) as group 2, but without the Red Food dye staining used for dead spermatozoa discrimination; (4) as group 2, but with double UV laser power (300 mW); and (5) as group 3, but with double UV laser power (300 mW). Sperm sorting was performed with a MoFLoSX flow cytometer at speeds of 3000 –5000 cells/s. Sorted fractions of X and Y spermatozoa were mixed again and stored for 24 h at 15 °C. A sperm chromatin structure assay (SCSA) was performed twice on each sorted sample, immediately after sorting and after 24 h. The chromatin of control samples was examined according to the same time schedule. The percentage of spermatozoa with damaged chromatin was calculated (COMP α-t) as well as standard deviation of the α-t parameter (SD α-t). The latter parameter, although less intuitive, is considered as even more precise than COMP α-t in chromatin investigations. The mean percentage of spermatozoa with abnormal chromatin was 1.12% (SD = 0.47) for control samples. The highest level of chromatin abnormality was noted for the 300 mW group with no dead cell discrimination (Red Food staining): 1.29% (SD = 1.05). After 24 h of storage, the mean level of chromatin abnormality increased to 1.97% (SD = 0.96) in control samples whereas that in all sorted samples was lower: from 1.06% (SD = 0.4) to 1.16% (SD = 0.62) in the 150 mW/non-Red Food-stained and the 300 mW/Red Food-stained groups, respectively. This difference appeared to be statistically significant (t; P ≤ 0.05). Interestingly, the percentage of abnormal spermatozoa decreased slightly after 24 h of storage in the 300 mW/Red Food-stained and the 300 mW/non-Red Food-stained groups ( –0.13% and –0.08%, respectively). Calculation of the SD α-t parameter showed statistically significant differences in chromatin abnormality between the control group vs. the 300 mW/non-Red Food-stained group immediately after sorting and the control group vs. the 150 mW/Red Food-stained group after 24 h of storage. In conclusion, although the statistically significant increase of chromatin damage was found after sexing in some investigated groups, it seems that the level of this abnormality is far too low to affect sexed semen fertility.

The objective of this study was to examine the substitution of soybean-origin phospholipids for egg yolk in Brahman bull semen extender. Semen was frozen in 3 different low-fat milk (1%) based extenders containing 10mgmL−1 of fructose and supplemented with: 8% of whole egg yolk (Extender 1, control), 8% rectified egg yolk (egg yolk granules were removed by double centrifugation at 3000g for 1h at 5°C; Extender 2), and 7.3mgmL−1 of phospholipids of soybean-origin containing 10% of phosphatidyl choline (Extender 3). All 3 extenders were supplemented with 1000IU of penicillin, 1mgmL−1 streptomycin and 150μgmL−1 lincomycin. The semen was collected by means of artificial vagina from 3 Brahman bulls, and AI was performed during the dry season between December and April in a tropical forest environment. The mean temperature for the region was 26–30°C, with mean rainfall of 900–1500mm/year and the relative humidity of 60–70%. Ejaculates with at least 60% motility were diluted in 2 steps as follows: in step 1, each ejaculate was split into 3 even parts and diluted at 26°C with each of the extenders containing no glycerol, and in step 2, 14% of glycerol was added in 15-minute intervals to a final glycerol concentration of 7%. Semen was aspirated into 0.5mL plastic straws (20×106 sperm/per straw), frozen 7cm above liquid nitrogen (LN2) for 8min, and then plunged into LN2. Straws were thawed in a water bath at 37°C for 30s. Each experiment was replicated 3 times (different collection days). Sperm viability was tested within artificial insemination trials. Results are based on the pregnancy rates of crossbreed Brahman cows determined by palpation 45 Days after AI and by calving rates. Data were compared by chi-square analysis. In Experiment I, a total of 157 cows were inseminated with semen collected from 3 different bulls (A, B and C) and frozen in 3 different extenders (1, 2 and 3; 3×3 factorial design). Bull A, Extender 1, 2 and 3 (n=19, 20 and 22); Bull B, Extender 1, 2 and 3 (n=20, 20 and 20) and Bull C, Extender 1, 2 and 3 (n=22, 15 and 24), respectively. Although semen from all 3 bulls frozen in Extenders 2 and 3 fostered numerically higher pregnancy rates (from 30% for Bull B and Extender 2 to 50% for Bull C and Extender 3) than in Extender 1 (from 23.5% for Bull C to 40% for Bull B), there were no differences (P&lt;0.05) between bulls with any of 3 extenders on the pregnancy rates. In Experiment II, a total of 117 cows were inseminated with semen collected from Bull B and frozen in Extender: 1 (n=37), 2 (n=48) and 3 (n=39). There were significantly higher (P&lt;0.05) calving rates for cows inseminated with semen frozen in Extender 2 and 3 (41.6% and 46.1%, respectively) than in Extender 1 (24.3%). It can be concluded that rectified egg yolk may improve viability of frozen semen, and that phospholipids of soybean origin can be successfully substituted for egg yolk in Brahman bull milk based semen extender.

Replacement of animal-origin components in extenders used for bull semen freezing is of high importance for individuals involved in cattle breeding. The experiment was designed to compare efficacy of 5 different semen extenders in cryopreservation of bull semen: sodium citrate-based extender containing egg yolk (CT), commercially available Bioxcell� (IMV Technologies, L'Aigle, France), and 3 custom-made homogenized plant lipidsbased, egg yolk-free extenders (Y-1, Y-2, and Lipo) . The objective was to determine whether homogenization procedures of lipids improve the quality of the extender. Lipid homogenates of custom-made extenders were prepared in Tris buffer using a high pressure homogenizer (Nira Saovi, Parma, Italy). Ten (Y-1) or 5 (Y-2) homogenization cycles were applied and then 8% glycerol was added. Lipid liposomes were produced by simultanous high pressure homogenization of lipids and glycerol supplementation (Lipo). Semen was collected from young bulls of 3 different breeds (Simmental, Polish Red, and Holstein; 1 ejaculate/bull). Each ejaculate with at least 70% motility was split into 5 parts and processed further by a standard freezing protocol: semen was diluted at 35�C with each of the 5 extenders to a concentration of 100 � 106 spermatozoa per mL, cooled to 4�C over 5 h, aspirated into 0.25-mL plastic straws, frozen in liquid nitrogen vapor to –140�C, and then plunged into LN2. Straws were thawed in a water bath at 37�C for 20 s. Sperm motility was estimated microscopically immediately after thawing and after 5 h of storage at 22�C. Immediately after thawing, flow cytometry and SYBR-14/PI staining were used for examination of sperm membrane integrity (live/dead assay). A total of 20 000 spermatozoa of each sample were counted. Student's t-test was used to estimate statistical differences between experimental groups. The mean sperm motility after thawing ranged from 45.6% (SD = 13.7) for CT (egg yolk extender) to 57.8% (SD = 7.1) for Lipo. A significant difference (P < 0.05) was observed betweenY-1 (50.0%, SD = 9.7) and Lipo and Bioxcell (56.1%, SD = 8.6). After 5 h of storage at 22�C, the mean motility for all tested bulls ranged from 25.0% (SD = 7.1) for CT to 42.2% (SD = 7.5) for Lipo. Significant differences were observed between Lipo (P < 0.01), Y-2 (P < 0.05) and CT, and between Y-1 and Lipo (P < 0.01). Mean percentage of 'live' spermatozoa with intact membrane after freezing/thawing was 51.85% (SD = 11.49) for Y-1, 45.72% (SD = 9.36) for Y-2, 47.57% (SD = 7.93) for Lipo, 45.47% (SD = 8.35) for Bioxcell, and 49.06 (SD = 11.59) for CT. No significant differences were observed except forY-1 and Bioxcell extenders (P < 0.05). It can be concluded that both methods of lipid/glycerol homogenization can be successfully applied in the preparation of bull semen extender. In addition, extensive lipid homogenization (10 cycles) produced more transparent extender that in turn improved visualization of sperm. Custom-made plant origin lipids homogenization may provide a valuable alternative for the preparation of extenders that more closely match the membrane composition of bull sperm cells and thus contribute to development of an efficient extender free of animal-origin components for bull semen freezing.

Moringa oleifera extract is a strong natural antioxidant that when was added to the semen extenders, it induced a cryoprotection to spermatozoa effect through elimination of the excess free radicals. So, the existing study intended for clarification of the consequence of extract of Moringa leaves (MLE) on bull spermatozoa after chilling and cryopreservation. MLE concentrations were 0% (control), 10, 20, 30, 40 and 50% (v/v) [MLE: TCF (Tris-citric-fructose diluent)] then 20% egg yolk was added, then the extended semen was assigned to the freezing protocol. Then, it was evaluated for (motility, alive, abnormality %, sperm membrane integrity % before and after freezing). Sperm motility was kept high with the concentration 10, 30 and 40% of MEEY till 8 days of chilling. The concentration 20% maintained sperm motility high till 7 days of chilling. Addition of MLE to TCF significantly (P<0.002) improved sperm motility in all concentrations except the 50% moringa enriched extender with egg yolk (MEEY) where sperm motility was maintained as the control. The use of MEEY maintained % of alive sperms and % of normal spermatozoal membrane (HOST%) as good as the control. In conclusion: moringa as a herbal supplement to semen diluents enhanced preservation in cooled and cryopreserved cattle bull semen.

This investigation was carried out during winter season on the semen of three mature, healthy breeding bulls each of Gir cattle and Murrah buffalo breeds. The aim was to assess the effect of different concentration of antioxidant Sericin (0.0, 0.1, 0.25, 0.50 and 1.0%, w/v) in standard Tris fructose egg yolk glycerol (TFYG) extender on cryopreservability of bovine semen based on sperm motility and oxidative markers in seminal plasma of freshly diluted and cryopreserved semen. The mean sperm motility observed in freshly diluted and frozen-thawed Gir bull semen, irrespective of Sericin levels, were 76.93±0.39 and 43.47 ± 0.58 % and in Murrah bulls 78.20±0.38 and 44.10 ± 0.48 %, respectively. The values of malondialdehyde (MDA, μmol/ml) in seminal plasma of freshly diluted and frozen-thawed semen of Gir bulls, irrespective of Sericin levels, were 21.68±0.38 and 24.99 ± 0.56, and in Murrah bulls 21.49±0.57 and 25.60±0.94, respectively. The corresponding values of superoxide dismutase (SOD, U/ml) were 1.77 ± 0.06 and 1.37 ± 0.05 in Gir and 1.18 ± 0.06 and 0.85 ± 0.04 in Murrah bulls, and those of glutathione peroxidase (GPx, nmol/min/ml) 417.10 ± 12.00 and 349.76 ±11.92 in Gir and 385.71±9.21 and 320.02±9.49 in Murrah bull semen. Sperm motility and activities of all three enzymes differed highly significantly (plessthan00.01) between stages. SOD was significantly (plessthan00.05) lower in buffalo than cattle semen. Inclusion of 0.5% and/or 0.25% Sericin in TFYG extender gave better protection to spermatozoa over other levels against ROS mediated injuries as the MDA production was significantly reduced with increased sperm motility and higher levels of SOD and GPx enzymes in the seminal plasma.

A study was designed to determine Kacang buck sperm membrane integrity and acrosome reaction as to the effect of different concentration of freeze drying fig fruit filtrate in tris egg yolk based extender. This study used 5 proven fertility Kacang goats aged 3-4 years, maintained by Faculty of Animal Sciences, Mataram University, Indonesia. Semen was collected by artificial vagina at every five days. The collected semen was divided into four aliquots in accordance to the treatments extender such as Control (0 gr), T1 (0.02 gr), T2 (0.04 gr) and T3 (0.06 gr) freeze drying fig fruit filtrate in tris egg yolk based extender (gr/v), respectively. Plasma membrane integrity and intact acrosome after re-concentration and preserved at 5ºC were assessed visually at 0 and every 24 hours for 5 consecutive days. The statistical significance of the result was evaluated by a one way ANOVA for completely randomized design analysis of variance. Data were presented as Mean±SD. Results suggest that the mean percentages of sperm membrane integrity in T0, T1,T2 and T3 at 96 h post extended and preserve at 5ºC were 34.3±5.3,  40.6±4.7,  44.8±5.4 and  42.1±5,1, respectively. The mean percentages of sperm acrosome intact were 16.4±4.8, 18.5±1.9,  21.6±3.1 and 19.6±2.8, respectively. The results of the study suggested that additional 0.04gr freeze drying fig fruit filtrate into tris egg yolk based extender have a significant preservation effect on both spermatozoa membrane integrity and acrosome intact of kacang buck.

High speed cinefluorography was used to track articulatory movements preceding and following full-mouth tooth extraction and alveoloplasty in two subjects. Films also were made of a control subject on two separate days. The purpose of the study was to determine the effects of dramatically altering the structural dimensions of the oral cavity on the kinematic parameters of speech. The results showed that the experimental subjects performed differently pre and postoperatively though the changes were in different directions for the two subjects. Differences in both means and variabilities of kinematic parameters were larger between days for the experimental (operated) subjects than for the control subject. The results for the Control subject also showed significant differences in the mean values of kinematic variables between days though these day-to-day differences could not account for the effects found pre- and postoperatively. The results of the kinematic analysis, particularly the finding that transition time was most stable over the experimental conditions for the operated subjects, are used to speculate about the coordination of normal speech.

Parameter evaluasi meliputi motilitas, viabilitas, dan membrane plasma utuh setelah pengenceran, ekuilibrasi dan thawing.  Evaluasi motilitas pasca thawing menunjukkan P5 52% berbeda nyata (P<0.05) dengan P1 42%, selanjutnya P5 dan P1 berbeda sangat nyata (P<0.05) dengan P2 8%, P3 6% dan P4 12%.  Viabilitas pasca thawing menunjukkan P5 65,4% tidak berbeda nyata (P>0,05) dengan P1 61,8%, akan tetapi P5 dan P1 berbeda sangat nyata (P<0.05) dengan P2 26,2%, P3 29,8%, dan P4 34%.  Membran plasma utuh (MPU) pasca thawing menunjukkan P5 66,2% tidak berbeda nyata (P>0,05) dengan P1 65,4%, akan tetapi keduanya berbeda sangat nyata (P<0.05) dengan P2 39%, P3 38%, dan P4 36,2%.  Disimpulkan kriopreservasi semen kambing boer dengan pengencer nira aren dan gliserol pada konsentrasi berbeda belum dapat dipergunakan sebagai sumber bibit berdasarkan standar nasional Indonesia.Kata Kunci : Kambing boer, semen, nira arenABSTRACTThe experiment was conducted to determine the effect of sugar palm juice as alternative extender for cryopreservation process of boer semen.Tris-glycerol-egg yolk (P1 73-7-20%), Sugar palm juice-glyserol-egg yolk (P2 74-6-20%, P373-7-20%, dan P4 72-8-20%), and andromed (P5) used as a extender  in the cryopreservation process of boer semen.  Sperm motility (%), live sperm (%) and sperm membrane integrity (%) were recorded after diluted, equilibration and freeze-thawing.  Result of post thawing motility showed that P5 52% was significantly different (P <0.05) with P1 42%, then P5 and P1 were significantly different (P <0.05) with P2 8%, P3 6% and P4 12%. Viability after thawing showed P5 65.4% was not significantly different (P> 0.05) with P1 61.8%, but P5 and P1 significantly different (P <0.05) with P2 26.2%, P3 29.8 %, and P4 34%. Spermmembrane integrity post-thawing showed P5 66.2% was not significantly different (P> 0.05) with P1 65.4%, but both were very significantly different (P <0.05) with P2 39%, P3 38% and P4 36.2%. Conclusions, sugar palm juice-glycerol-egg yolk with differentconcentrationsineffectively as an alternative extenderin cryopreservation of boer semen.Keywords: boer goat, semen, sugar palm juice
