ABSTRACT The objective of the study was to determine whether or not there is a correlation between thermoresistance tests (TT) after semen thawing and pregnancy rate (PR) after fixed-time artificial insemination (FTAI). Four different TT were performed on ten samples used for AI; a rapid test (RTT) (30min / 46°C) and three slow tests (STT): STT1 (60min/38°C), STT2 (180min/38°C), and STT3 (300min/38°C). Two hundred and fifteen multiparous crossbred cows were submitted to FTAI under the following protocol: on day zero (d0) the animals received a P4 device +EB; on d7 PGF2α; on d8 P4 was removed and eCG+EC were administered; IATF was performed on d10. Three gestational diagnoses (G D) were performed on d40, d70 and d120. The mean sperm motility (%) in RTT and STTs were 19.84±6.13, 28.55±10.48, 17.62±5.87 and 8.63±3.46, respectively, and TP in the three DG 61.86%, 57.67%, and 55.81%, respectively. Through Person test a significant negative correlation (P< 0.05) was found between STT2 and PR at 60 days (r= -0.644) and between STT3 and all TPs (r= -0.774, -0.752, 0.748). It was concluded that TT parameters are not able to determine correlation between semen quality and TP.

Abstract This study compared the semen quality traits between Etawah grade (EGB) and Senduro bucks (SB) raised in Singosari National Artificial Insemination Center, Indonesia. A total of 96 ejaculated semen were collected from three EGB and three SB with an average age of three years. The ejaculates were evaluated for semen volume (SV), spermatozoa concentration (SC), total spermatozoa (TS), spermatozoa motility (SM), post-thawing spermatozoa motility (PTSM), the recovery rate of spermatozoa motility (RRSM), and frozen semen production (FSP). Data of SV, SM, PTSM, and RRSM were compared using the Mann-Whitney U test. While the data of SC, TS, and FSP were analyzed using an independent t-test. The results showed that SV, SM, PTSM, and RRSM were not significantly differed (P>0.05) between breeds. Whereas, SC, TS, and FSP of EGB were significantly higher (P<0.05) than SB. Therefore, it can be concluded that Etawah grade bucks can produce higher total spermatozoa and as a result higher frozen semen production for artificial insemination as compared to Senduro bucks.

The purpose of this research was to analysis the value of repeatability and correlation among the traits affecting the production of frozen semen from Holstein’s bull in Indonesia. Repeatability and correlation were calculated based on the data of frozen semen production of 15.699 records from 44 Holstein bulls at Singosari Artificial Insemination Center (SAIC) and 8.935 records from 39 Holstein bulls at Lembang Artificial Insemination Center (LAIC). Repeatability for volume, motility, fresh semen concentration and frozen semen production was evaluated by intraclass correlation method. The repeatability values of LAIC for volume, motility, fresh semen concentration and frozen semen production were 0.60; 0.54; 0.37 and 0.47. The repeatability values of SAIC for volume, motility, fresh semen concentration and frozen semen production were 0.54; 0.30; 0.43 and 0.29. The linear correlation value between volume, motility and fresh semen concentration with the amount of semen produced per collections were 0.41, 0.36, and 0.58. Concentration was the most factors influencing the number of frozen semen produced. The effectiveness of the selection of Holstein's frozen semen producing could be determined by the value of repeatability and the phenotypic correlation among semen quality traits such as volume, motility, concentration and frozen semen production.

The aim this study was to evaluate the effects on artificial insemination (AI) of minimizing oxidative stress by adding an antioxidant into the sperm microenvironment. For that purpose, semen of bulls with different seminal quality was evaluated in nature and after addition of extender with and without antioxidant, followed by freezing and thawing, with respect to thiobarbituric acid reactive substances (TBARS) concentration, total antioxidant capacity (TAC), and AI success. TBARS is an indicator of lipid peroxidation and TAC measures free radicals. Twelve ejaculates from 5 bulls were treated with Tris egg yolk extender (CE) and in half of each ejaculate the extender was supplemented with 200 μL of Trolox (AE). Three of these 5 bulls had high-quality semen (mean 11.9 ± 5.9 total defect, 7.7 ± 3.1 major defect, and 4.2 ± 3.9 minor defect) and 2 animals had poor-quality sperm (mean 31.9 ± 9.7 total defect, 26.3 ± 8.5 major defect, and 5.6 ± 5.0 minor defect) (P < 0.05). For AI, 300 Nelore heifers were divided in 10 groups and the females in each group were inseminated with semen of the same bull and extender treatment. To evaluate oxidative damage, TBARS concentration was measured to indirectly determine malondialdehyde (lipid-peroxidation metabolite) concentration, whereas TAC was measured using myoglobin, as a source of radicals, which interact with a chromogen 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS), whose cation radical is spectroscopically detectable. The latency phase (lag) in the accumulation of ABTS cation is proportional to the antioxidant concentration. The pregnancy rates 60 days after AI were analyzed by chi-square test, and data of free radical production were evaluated by ANOVA, followed by the Tukey test with significance level of 5%. Reactive oxygen species (ROS) production in nature semen (0.351 nmol of TBARS in 50 × 108 spermatozoa) was lower (P < 0.05) when compared to diluted semen (0.367 nmol of TBARS in 50 × 108 spermatozoa). No difference (P > 0.05) between extenders was observed after thawing. The bulls with poor-quality semen presented total ROS production (0.967) superior (P < 0.05) to that of bulls with good-quality semen (0.753). Although the use of antioxidant in the extender did not decrease ROS and TAC production (P > 0.05), pregnancy rates after AI in bulls with poor quality semen with AE (60.0%) was superior (P < 0.06) to that in bulls with high-quality sperm with AE (56.6%). In conclusion, bulls with poor-quality semen present higher ROS and TAC production, and the use of antioxidant in the extender for cryopreservation with poor-quality bovine semen, in spite of not decreasing ROS and TAC production, improves pregnancy rates.
