Informativeness of eleven microsatellite markers suggested for parentage control in cattle by the International Society for Animal Genetics (ISAG) was studied in Finnish Ayrshire and Holstein-Friesian populations. Calculations were based on a sample of 100 non-sib artificial insemination bulls. Assuming one known parent the nine loci suggested for routine testing exhibited exclusion probabilities of 99.84% in the Ayrshires and 99.91% in the Holstein-Friesians. The addition of markers INRA23 and TGLA53, recommended for further investigations, increased the attained values to 99.94% in Ayrshires and to 99.98% in Holstein-Friesians. The recommended core set of six microsatellites provided a combined exclusion probability of 98.25% in Ayrshires and 99.32% in Holstein-Friesians. Although the combined values were high in general, a relatively low level of polymorphism was detected in some instances.;

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 use of liquid semen for artificial insemination program of Etawah crossbreed goat (PE) is an alternative to replace frozen semen which is constrained by limited and expensive facilities. Production of liquid semen is faster than frozen semen, but the viability of liquid semen which preserved with a standard extender such as tris egg yolk is very short. The purpose of this study was to determine the viability of PE goat semen in egg yolk tris substituted with energy sources such as glucose, galactose, and mannose and to determine the most efficient energy source for semen preservation. This research was conducted from August to September 2018 at the Artificial Insemination Center in Lembang, West Java. This study was designed in a randomized block design (RBD) consist of three experimental groups divided into five groups. Fresh semen of PE goats were preserved using extender which energy source has been modified. Results showed that using glucose in PE goat semen extender produced the best motility among other groups (64.29 ± 9.2%). The highest viability was found in extender with fructose substitution (86.76 ± 2.3%). The longest viability of liquid semen was found in the extender with glucose substitution. It lasted for six days.

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.

Holstein Bulls

Background and Aim: Holstein cows and heifers are widely bred in Indonesia by artificial insemination (AI) to increase population and milk production. Sperm fertility is modulated by genetic factors, but the analysis of sperm quality is still based on macro- and microscopic characteristics. This study aimed to analyze both sperm quality and proteins of Holstein bulls at different fertility levels. Materials and Methods: The frozen semen samples were collected from the Indonesia National AI Center. They were classified based on the reproductive efficiency data and were grouped into high fertile (HF) and low fertile (LF). Sperm qualities were evaluated by microscopic evaluation. The Holstein sperm proteins were extracted using phenylmethanesulfonyl fluoride as a protease inhibitor and the benzidine detergent extraction method. Discontinuous sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was conducted to analyze the molecular weights (MWs) of the sperm proteins. The data obtained were analyzed by a t-test using the one-factor bull fertility level, and Spearman's correlation analysis was used to identify the correlation between the sperm microscopic evaluation parameters and protein bands. Results: The sperm motility post-freeze thawing was not significantly different between the HF and LF (p>0.05). The HF level had a higher percentage of viability, intact plasma membrane integrity, and intact acrosomes than the LF (p<0.05). Five protein bands were found in the SDS-PAGE of sperm proteins of Holstein bulls with different concentrations. Sperm proteins with MWs of 17.51 kDa, 14.87 kDa, 33.71 kDa, and 41.97 kDa were abundant in the Holstein bulls with an HF level, while 55 kDa proteins were abundant in the LF level of Holstein bulls. The sperm of Holstein bulls in the HF level contained proteins of about 33.71 kDa that were not detected in the LF. Conclusion: The sperm protein with a molecular weight of 33.71 kDa was predicted to be a specific protein biomarker that influences bull fertility. Sperm fertilization abilities were also determined by the sperm proteins, the morphology of sperm acrosomes, and the quality of plasma membranes. This method can be used to select bulls with high fertility to increase the population of Holstein bulls.
