17 EFFECT OF LOCAL TREATMENT OF SEMINAL VESICULITIS ON THE QUALITY OF EQUINE FRESH 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.

ABSTRACT. Maggot Hermetia illucens (Maggot Black Soldier Fly, MBSF) is an alternative protein source besides soybean meal (SBM) which may be used as a feed for improving the quality of semen particularly in Garut rams to support prolific nature. The aims of this study were to analyzed and compare the impact of different protein sources in feed on semen quality of Garut rams, and to assess the prediction ability of Garut rams to serve ewe in small-scale breeders in West Java, Indonesia. This study was conducted using a completely randomized design with 3 treatments and 4 replications, consisted of Brachiaria humidicola (BH) grass and T1 (concentrate contains 20% of SBM), T2 (concentrate contains 10% of SBM and 10% of MBSF), and T3 (concentrate contains 20% of MBSF). The parameters measured were feed consumption, semen quality (macroscopic and microscopic characteristics), also a potential ability of rams to serve ewe. The results showed there were no significant effect on protein consumption, semen volume, semen pH, semen color and consistency, sperm mass movement, sperm motility, sperm concentration, sperm morphology, and prediction potential ability to serve ewe. However, the result showed a significant effect (P0.05) on sperm viability and sperm plasma membrane integrity. Sperm plasma membrane integrity of ram feed with T3 was better than T1 and T2 (P0.05). The prediction potential ability rams to serve ewes on MBSF treatment was 38 heads, while in T1 and T2 were 43 and 57 heads, respectively. In conclusion, MBSF can be an alternative source of protein besides SBM to improve the semen quality of Garut rams. ABSTRAK.

Several factors can interfere with sperm cryopreservation resistance, especially the genetic factors and those related to the plasma membrane composition of the sperm and seminal plasma. However, it is still unclear if the same factors that confer freezing resistance will perform the same role during the cooling process. Thus, the aim of this study was to determine the relation between the resistance to freezing and cooling processes in stallions. Two ejaculates from each of 75 stallions were used. All animals showed good quality of fresh semen (total motility higher than 60% and plasma membrane integrity higher than 50%). After collection, the semen was diluted 1 : 1 with commercial skim milk-based extender (Botu-SemenTM, Botupharma, Brazil) and then a part was designed to cooling and the another to freezing. The cooled semen was divided into 2 groups: Group PS, in which the semen was diluted with Botu-SemenTM at a concentration of 50 × 106 sperm mL–1, and Group SPS, which was subjected to a centrifugation at 600 × g for 10 min and resuspended with Botu-SemenTM at 50 × 106 sperm mL–1. Semen samples from both groups were placed in the same cooling passive system for a period of 24 h/5°C. To accomplish the freezing process, the semen sample was subjected to centrifugation at 600 × g for 10 min. The supernatant was discarded, and the pellet was re-suspended in a Botu-CrioTM. The straws were frozen according to the manufacture. The sperm parameters from fresh semen, cooled semen for 24 h with and without seminal plasma, and frozen semen were evaluated for kinetics by computer-assisted semen analysis and for plasma membrane integrity (IMP%) by epi-fluorescence microscopy. The animals were classified in relation to their resistance to cooling and freezing processes as follow: “bad coolers” – reduction in sperm total motility and in plasma membrane integrity higher than 35% after 24 h of cooling in samples with seminal plasma; “good coolers” – reduction in sperm total motility and in plasma membrane integrity lower than 35% after 24 h of cooling in samples with seminal plasma; “bad freezer” – sperm total motility lower than 40% and progressive motility lower than 20% in seminal sample after thawing; “good freezer” – sperm total motility higher than 60% and progressive motility higher than 30% in seminal sample after thawing. The comparison between the resistance to cooling and freezing processes was performed by Fisher's exact test. The level of significance was 5%. No difference (P < 0.05) between the resistance to cooling and freezing processes was observed. The percentage of stallions “good freezer” and “good cooler” was 54%, “good freezer” and “bad cooler” was 22.6%, “bad freezer” and “good cooler” was 12%, and “bad freezer” and “bad cooler” was 10.6%. Within stallions classified as “good freezer” and “bad cooler,” 52.9% also were “good cooler” when the seminal plasma was removed before the cooling process, and 47.1% remained as “bad cooler.” The result of this study demonstrates that there is a strong relation between the resistance to cooling and freezing processes in stallions. In stallions categorized as “bad cooler,” the seminal plasma presents a major influence on the quality and longevity of cooled semen.

Abstract This study aimed to compare post-thaw quality of boar semen following freezing in an ostrich egg yolk lipoprotein (LPFo) extender supplemented with 0%, 0.25% and 0.50% Orvus Es Paste (OEP). Sperm assessments included total motility (TMOT), mitochondrial function (MF), plasma membrane integrity (PMI) and acrosome integrity (normal apical ridge, NAR). Considerable variations among boars and OEP treatments had a significant effect (P < 0.001) on post-thaw sperm characteristics. It was observed that post-thaw sperm characteristics were significantly compromised in semen samples frozen in the absence of OEP. By contrast, lactose-LPFo-glycerol extender supplemented with either 0.25% OEP or 0.50% OEP markedly enhanced post-thaw sperm characteristics. In all boars, there were no marked differences in post-thaw sperm TMOT between the freezing extenders supplemented with 0.25% and 0.50% OEP. However, a decline in the percentage of post-thaw motile spermatozoa was more pronounced in the extender supplemented with 0.50% OEP following a 120-min incubation period. Furthermore, the proportions of frozen-thawed spermatozoa with MF, PMI and NAR acrosomes varied significantly among the boars in the OEP-supplemented extenders. The findings of this study indicate that different OEP concentrations, in the presence of ostrich egg yolk lipoproteins, could have varying effects on post-thaw sperm survival

ABSTRACT Background Wide variation in fertility rates is observed when using frozen bull semen, even when the bulls have met quality standards for semen production. Therefore, a simple and reliable test to assess the freezing potential of bull semen based on the analysis of fresh semen or blood would be of great value. Attention is now turning to assessment of seminal plasma components such as proteins and elements. In the present study, the concentrations of macro- and microelements in fresh bull semen plasma and in serum and their correlation with quality characteristics of fresh semen and with semen quality after freezing and thawing were determined. Ejaculates were collected from 30 mature bulls, and semen volume, concentration, sperm motility, morphology, tail membrane integrity, plasma membrane permeability and DNA fragmentation were determined on the day of collection and after freezing and thawing. The concentrations of macroelements (Na, Mg, K and Ca) and microelements (Cu, Fe, Zn and Se) were determined in the seminal plasma and serum. The semen samples were classified into satisfactory and unsatisfactory groups according to the fresh semen quality. Results Zinc and Se levels measured in serum were associated with almost all fresh and frozen-thawed semen quality characteristics, while Fe levels were associated only with acrosomal defects in fresh semen. Zinc and Fe levels in fresh seminal plasma were associated with various quality characteristics of fresh and frozen-thawed semen, while Se level in fresh seminal plasma was not associated with any of the semen quality characteristics. Conclusions Microelements were shown to be useful as biomarkers involved in the analysis of bull sperm quality and could be used as an additional tool to predict bull semen quality after freezing and thawing. Our results confirm that the analysis of Zn and Se levels in serum and Zn, Cu and Fe levels in fresh seminal plasma can provide information to discriminate between bull semen samples with spermatozoa with high or low cryotolerance.
