This study was conducted to determine the effect of crude protein tyrosine kinase (PTK) isolates supplementation into skim milk-egg yolk based diluent to maintain the quality of Merino ram spermatozoa.  Four ejaculates of two Merino rams were divided into two groups for the control group (P0): Merino ram semen was diluted in skimmed milk-egg yolk based diluent, and the treatment group (P1): Merino ram semen was diluted in skim milk-egg yolk based diluent contained crude PTK 1,597 mg/ml diluent. All diluted semen was equilibrated for 2 hours at 5 °C and filled into 0.25 mL French straws. The filled straws were placed on steel racks (Cooltop, Minitube) held in liquid nitrogen vapour for 10 minutes at –140 °C, immersed immediately in liquid nitrogen at –196 °C, and stored for 48 hours for  later assessment. Post-thawed semen samples were evaluated for spermatozoa motility, viability, and morphological abnormality. The results showed that the spermatozoa motility of fresh semen of Merino ram was 82.5 ± 2.89, which was qualified for freezing. The post-thawing spermatozoa motility, viability, and morphological abnormalities of Merino ram in the P1 group were 34.11 ± 3.26%, 38.00 ± 3.00%, and 12.89 ± 4.54%, respectively. It were higher (p <0.05) than the control group of 24.44 ± 2.9%, 26.67 ± 3.32%, and 21.11 ± 3.02%. It was concluded that the addition of crude PTK isolates of 1.597 mg/ml skim milk-egg yolk diluent improved the quality of post-thawed spermatozoa of Merino ram.

Spermatozoa in fresh semen of Sapudi ram has a limited life span. The storage of semen in cold temperatures (5 °C) is intended to prolong the spermatozoa's life. However, storage in cold temperatures can lead to increased production of reactive oxygen species (ROS). This condition reduces the quality of spermatozoa. The purpose of this study was to determine the effect of alphatocopherol supplementation in skim milk-egg yolk extender on viability, motility, and plasma membrane integrity of Sapudi ram spermatozoa. Fresh semen derived from Sapudi ram was divided into four treatment groups. Control treatment (P0): semen was added in the extender of skim milkegg yolk without alpha-tocopherol. Three other treatments: P1, P2, and P3 semen were added in skim milk-egg yolk extender with the supplementation of 0.25, 0.5, and 1 gram alpha-tocopherol/ 100 mL extender, respectively. The results showed that the viability, motility, and integrity of the spermatozoa plasma membrane decreased gradually according to the storage length. Supplementation of skim milk-egg yolk extender with 0.5 gram of alpha-tocopherol/100 mL (P2) was able to maintain spermatozoa quality longer (p <0.05) than the control group. It can be concluded that alpha-tocopherol with a concentration of 0.5 g/100 mL of skim milk-egg yolk extender effectively maintains the quality of Sapudi ram spermatozoa in storage at 5 ° C.

Artificial insemination has proven to be an effective method for increasing population size and genetic quality of Kacang goats. However, innovation is required to maintain the quality of Kacang goat semen in storage. This study aimed to examine the effects of supplementing the 150 kDa protein assumed as IGF-I complex derived from bull seminal plasma in skim milk-egg yolk extender on the quality of Kacang goat sperm stored at 5°C. Twelve ejaculates collected from three Kacang goats were divided into three groups. In the control group (T0), the ejaculates were extended with skim milk-egg yolk only. In the treatment groups (T1 and T2), the ejaculates were extended with skim milk-egg yolk supplemented with the IGF-I complex protein at 12 μg and 24 μg/100 mL, respectively. The extended semen was stored at 5°C, and the viability, motility, intactness of the plasma membrane, malondialdehyde concentration, and apoptotic sperm percentage were evaluated daily for five days. The results showed that the T1 was the most effective treatment for maintaining Kacang goat semen at a quality acceptable for artificial insemination over five days of storage at 5°C. However, the T0 and T2 groups retained acceptable qualities for only three days at 5°C. It could be concluded that supplementation of 12 μg of the 150 kDa protein derived from bull seminal plasma per 100 mL extender successfully extended the life span of Kacang goat sperm for five days.

This research was conducted to investigate the effect of various concentrations of lactose supplementation in Tris extender for maintaining the quality of Etawa crossbreed goat epididymal spermatozoa stored at 3-5° C. Semen in the control group was diluted with a tris extender containing 20% egg yolk without lactose. Semen in the test groups was diluted with a tris extender containing 20% egg yolk and added with 0.3% (0.3 g per 100 mL extender) and 0.6% lactose for group TL1 and TL2, respectively. Parameters evaluated of the fresh epididymal spermatozoa were motility, concentration, percentage of live, and abnormality of spermatozoa, while for diluted-spermatozoa were motility and percentage of live spermatozoa. Spermatozoa observation was conducted until it reaches 40% motility. The results showed that the mean percentage of motility, live sperm, concentration, and abnormality of epididymal spermatozoa were 70%; 81%; 3,220x106 cells/mL; and 4.30%, respectively in all group. After dilution, the percentage of motility and live spermatozoa were also 70% and 81.00±1.58%, respectively in all groups. The decreasing of spermatozoa motility was observed on day 4 of storage, in which percentage of spermatozoa motility in control group (40.00±0.00%) was significantly lower (P<0.05) than those in TL1 (44.00±2.24%) and TL2(45.00±0.00%) groups. Percentage of live spermatozoa in control (63.20±2.68%) was not significantly different (P>0.05) than TL1(65.40±1.95%) and TL2 (65.60±1.95%). In conclusion, the supplementation of lactose into Tris extender could maintain the epididymal spermatozoa of Etawa crossbreed for 3 days of storage at 3-5° C.

Background: New methodologies have been developed seeking to maximize pregnancy rate in female dogs created in commercial kennels, and also in order to maintain the quality of canine semen after dilution, refrigeration or freezing. One of the main factors that generate damage to sperm is oxidative stress, to minimize sperm damage, selenium and antioxidants like vitamin E are administered, by oral administration, seeking to improve the quality of semen. The objective was to study the effect of vitamin E and selenium, by oral administration, in the quality of fresh, refrigerated and frozen semen in adult dogs French Bulldog breed.Materials, Methods & Results: Semen samples were collected from 5 adult dogs, French Bulldog breed, being 2 semen drawing before the daily oral supplementation with vitamin E and selenium (ESE®) and semen drawing at 20, 40 and 60 days after the beginning of oral supplement. The ejaculated samples were diluted in TRIS - fructose citric acid (3.28 g TRIS-hydroxy-methyl-amino-methane, 1.78 g of citric acid monohydrate and 1.25 g of D - fructose, dissolved in 100 mL of distilled water and added of 20% egg yolk and 6% of glycerol. The characteristics evaluated in fresh semen were: volume (mL), color, appearance, concentration (x106 / mL), sperm motility (%), sperm strength (1 to 5) and morphology (%). For refrigerated and frozen semen were analyzed: sperm motility (%), sperm strength (1-5) and morphology (%). Diluted semen samples were centrifuged at: 1500 g/10 min and “pellets” formed by sperm of each ejaculated, detached from the tube wall were diluted homogeneously in the diluent TRIS type up to the final volume of 1.5 mL. After that, packaged in 0.5 mL French straws, kept under refrigeration at 5ºC/4 h, placed in nitrogen vapor at -120ºC/15 min, and dipped in liquid nitrogen at -196ºC and then stored on identified rachis and stored in liquid nitrogen container until the time of thawing in  water bath at 37°C/30 s for semen microscopic analysis. Data from fresh, refrigerated and frozen semen were statistically analyzed by analysis of variance and the average compared by 5% of Tukey test. Fresh semen sperm concentration differed (P < 0.05) between the samples, rising after 40 days after the beginning of oral supplementation with selenium and vitamin E. For the spermatic strength, better score (P < 0.05) was observed at collection 4, in 40 days after the beginning of oral supplementation to dogs. For fresh and refrigerated semen, the total defects, defects of head, acrosome and tail did not differ (P > 0.05) between the samples. Total sperm defects and minor head and tail defects did not differ (P > 0.05) between the samples in post-thawing. Regarding the acrosome defects after thawing, there was a significant reduction (P < 0.05) in samples performed 40 and 60 days after the beginning of oral supplementation with selenium and vitamin E.Discussion: Attention should be paid for what purpose the extenders within the refrigeration or freezing biotech will be used. The managed supplement, by oral administration, containing selenium and vitamin E, influenced beneficially raising the sperm concentration in fresh semen and decreasing the acrosome defects in frozen semen. Oral administration of supplementation with selenium and vitamin E is recommended for improving the quality of fresh and frozen semen in dogs.

The fertility of Merino ewes artificially inseminated with semen diluted tenfold in milk or buffered glucose solution was lower than that of a control group of ewes inseminated with the same number of spermatozoa in undiluted semen. By means of centrifugation, the concentration of spermatozoa in the insemination dose of diluted semen was raised to match that of the undiluted semen and then the effect of dilution on fertility was eliminated for the glucose-diluted semen, but not for the milk-diluted semen. Respective percentages of ewes not returning to oestrus and ewes lambing were, after insemination with undiluted semen, 60.5, 46.7; with milk-diluted semen, 55.9, 40.2 and after reconcentration 56.0, 38.0; with glucose-diluted semen, 48.2, 35.3, and after reconcentration 62.1, 46.1. In another experiment, the percentage of ewes lambing after insemination with undiluted semen, with semen diluted tenfold with glucose, and with semen diluted with a ribose mixture and chilled at 5°C for 24 hr were respectively 67.0, 58.0, and 26.1. Both diluents contained 6% (v/v) egg yolk and diluted semen samples were reconcentrated to the original sperm density of the semen immediately before insemination.

The aim of the study was to evaluate the effect of two different extenders on sperm characteristic before equilibration and post-thaw in the endangered Old Kladruber stallions. Also, the response of individual stallions to the extenders used was tested. Semen was collected from six stallions every other day within one week. After centrifugation of the collected sperm-rich fraction, the supernatant was removed and sperm pellets were divided to two aliquots; these were diluted either with Gent (Minitube, Germany) or privately manufactured lactose-EDTA-egg yolk extender (Lact). Three cryopreserved insemination doses (IDs) from each extender (Gent and Lact) were prepared for each stallion from one collection (108 samples from six stallions in total). As a parameter of quality, the motility (computer assisted sperm analysis), viability (fluorescence staining), and morphology (eosin/nigrosine staining) were evaluated after dilution with freezing extenders (fresh) and after thawing (frozen-thawed). The different effects of chosen extenders on the quality of fresh semen were only manifested in higher kinematic parameters of sperm when the Lact extender was used. However, in frozen-thawed samples, the Gent extender yielded significantly better results in all of the evaluated parameters. The representation of sperm subpopulation was significantly influenced by extender in fresh as well as frozen-thawed samples; moreover, we found a significant effect of freezing on the distribution of these subpopulations. The response of individual stallions to chosen extenders was evident in the different quality of fresh as well as frozen-thawed IDs; Gent extender yielded better frozen-thawed IDs. Based on our results, among others describing quality parameters of ejaculate in endangered Old Kladruber stallions, we can recommend using Gent extender for the production of frozen-thawed IDs.
