The aim of the study was to search for new mutations in the previously studied gene loci of follicle-stimulating hormone receptor (FSHR), inhibin α (INHA), inhibin β A (INHAB), prolactin (PRL), transition protein 2 (TNP2), and sperm flagella 2 (SPEF2) by sequencing, as well as the search for associations of previously identified mutations at these loci with fresh semen quality in Russian Holstein bulls. Phenotypic data from 189 bulls was collected. Data was analyzed for most bulls for three years of semen collection. The maximum value of each semen quality indicator (doublet ejaculate volume, sperm concentration, progressive motility and total number of spermatozoa) were selected. SNPs were identified in the FSHR, INHA, INHAB, TNP2, SPEF2 genes. The PRL gene did not have polymorphism. Significant (p < 0.05) associations of polymorphisms in the FSHR gene with double ejaculate volume, concentration and total number of spermatozoa were identified. Polymorphism in the INHA gene was significantly associated (p < 0.05) with sperm concentration. Polymorphism in the INHAB gene was significantly associated (p < 0.05) with doublet ejaculate volume and total number of spermatozoa. Polymorphisms in the TNP2 and SPEF2 genes did not have significant associations with semen quality. The SNPs studied in our pilot work may be considered as candidate genetic markers in the selection of bulls.

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.

AbstractTen Holstein bulls, 4 to 5 years old were used to study the effect of cooling the bulls on their semen quality. Five bulls were sprinkled with water for 15 min five times a day throughout a 6-week period of the summer season (hot-dry) in Saudi Arabia, and the other five bulls acted as the control and were not sprinkled with water. Semen quality was improved significantly during the cooling period. This improvement was evident from the significant increase in sperm motility (P < 0·01) and decrease in the percentage of both dead and morphologically abnormal (primary and secondary) spermatozoa per ejaculate of cooled bulls (P < 0·01). The effect of cooling was more marked through the last 3 weeks than during the first 3 weeks of the experimental period. Ejaculate volume, sperm concentration and hence total sperm counts did not differ significantly between the cooled and the non-cooled bulls. Concerning the type of abnormal spermatozoa, the overall secondary abnormality was higher than the primary in both the cooled and the control groups, with higher values for the control (P < 0·01). Only the mid piece showed higher primary defects than the secondary. The pyriform heads, the coiled mid pieces and tails and the bent tails were the main sources of variations (P < 0·01) in the incidence of sperm abnormality between the cooled and the non-cooled bulls. Cooling the bulls during the heat stress period also lowered their rectal temperature and increased blood haemoglobin level without affecting the packed cell volume

     This study was undertaken to explore the adding effect of manganese chloride (MnCl2), co-enzyme Q10 (Co-Q10) as well as α-lipoic acid to Tris extender on Freeze ability of Holstein bulls’ semen. This study was carried out at the department of artificial insemination at the Directorate of Animal Resource, Ministry of Agriculture in Abu-Ghraib, Baghdad for the duration from October\ 2013 to Jun\ 2014, including three experiments. Seven Holstein bulls of 3.5-4 years old were used in this study. Semen was collected via artificial vagina by one ejaculate/ bull/ week. The assessments were conducted for fresh semen, which was later pooled, equally divided for various treatments within each experiment, using Tris extender. In the first experiment, pooled semen was divided into three groups. First group was diluted with Tris only. Manganese chloride was added to Tris extender (0.7 mM) in the 2nd group while in 3rd group (0.9 mM) of the Manganese chloride was used. In the second experiment, semen was divided equally into three groups. The first group was considered as a control group diluted with Tris only. Co-enzyme Q10 was added to 2nd (0.2 mM) and 3rd groups (0.5 mM) treatments respectively. In the third experiment, semen was divided into three groups. The first group was diluted with Tris only (control group). While the 2nd and 3rd groups were added 0.5 and 1.0 mM α-lipoic acid respectively. The effect of these additions on Holstein bulls semen quality was studied during different periods (48 hours, one, two and three months post cryopreservation) for three experiments. The results revealed that the addition two levels of the MnCl2 (2nd and 3rd, experiment 1), Co- Q10  (2nd and 3rd, experiment 2) and α- lipoic acid (2nd and 3rd experiment 3) led to significant increases freezability as compared with control groups during all the experiment periods. In conclusion, the addition of MnCl2, Co-Q10 and α-lipoic acid led to improved post-cryopreservation semen quality of Holstein bulls. This will in turn enhance fertility rate of artificially-inseminated cows and owners economic income consequently.

(Effect of supplementation of vitamin E, Selenium and Zinc mineral against to nutrient consumption, production and quality cement simental cow)ABSTRACT. Simental bulls often experience a decline in production and semen quality in the rainy season, which have a higher humidity and high rainfall. This study aims to maintain nutrient consumption, production and semen quality Simental bulls during the rainy season through the supplementation of Vitamin E, Selenium and Zinc Minerals. The study was conducted in July-December 2012 at the Artificial Insemination Center (BIB) Unggaran. The research material used in this study were 12 males Simental cows BIB Unggaran grouped by age. The experimental design used in this study is a randomized block design (RBD) with 3 treatments T1 (ration + Vit. E), T2 (ration + Vit. E + Se), T3 (ration + Vit. E + Se + Zn) and 4 groups as replicates. Parameters measured were dry matter intake and nutrient consumption, production and semen quality. Cement production was measured from fresh semen volume during the study, whereas semen quality measured motility and concentration of spermatozoa from fresh semen. Data consumption of dry matter and nutrient intake obtained were processed using analysis of variance, followed by Duncan test. While data on production and semen quality were analyzed descriptively. The results showed that the combination of vitamin E supplementation, minerals Selenium and Zinc did not affect dry matter intake, total digestible nutriens and crude protein, but resulted in a decrease in the percentage of shelter, semen volume, sperm motility and concentration smaller than before treatment. Treatment T1, T2 and T3 resulted in a decrease in the number of shelter respectively 41,55%, 19,56% and 13,63% compared to before treatment, whereas a decrease in semen volume unchanged at 44,9 %, 43,7% and 40,99%. Sperm motility due to treatment T1, T2 and T3 respectively decreased by 55,87%, 22,10% and 13,63% compared to before treatment. In line with sperm motility, sperm concentration in treatment T , T2 and T3, respectively decreased by 49,16%, 22,85% and 14,88%. The conclusion is a combination of vitamin E supplementation, minerals Selenium and Zinc can prevent the decline in cement production, sperm motility and sperm concentration Simental bulls during the rainy season.

The Bermeya goats are an endangered autochthonous breed distributed in the north of Spain. To ensure their genetic diversity and long-term survival, morphological and functional parameters of the semen must be known in order to preserve the current genetic stock in a germplasm bank. The aim of this work was to establish basic characteristics and post-thaw survival of Bermeya goat's semen obtained by electro-ejaculation, that is not well described in the literature. The semen was collected by electro-ejaculation from 7 bucks, 1 to 7 years old, twice per week, for 9 weeks (n = 83). Fresh semen was evaluated for volume (V), concentration (C), motility, morphology, functional integrity of the sperm (spz) membranes (hypoosmotic swelling test; HOST), and acrosome integrity rate (NAR). Individual and progressive sperm motility were analyzed by means of a computer-assisted sperm analysis system (CASA: SCA 2002�, Microptic, Barcelona, Spain) immediately after dilution with the extender at 37�C, and after cooling to 4�C; five fields per sample (diluted to 204 � 106 spz mL–1) were evaluated under a phase contrast microscope (100�). The NAR and morphological abnormalities of sperm head, midpiece, tail, and cytoplasmic droplets were determined by counting 100 spz under 1000�. For freezing, ejaculates with at least 80% motile spz were diluted at 32�C with Krebs-Ringer solution containing 20% egg yolk and 14% glycerol to a final concentration of 400 � 106 spz mL–1, cooled to 4�C for 90 min, aspirated into 0.25-mL plastic straws (IMV�, L'Aigle, France), frozen at 7 cm above liquid nitrogen (LN2) phase for 10 min, and then plunged into the LN2. Straws were thawed in a water bath at 39�C for 30 s for post-thaw survival analysis. Data were analyzed by the GLM and FREQ procedures (SAS; SAS Institute, Inc., Cary, NC, USA) and expressed as means � standard error. Fresh semen characteristics were: V = 1.7 � 0.1 mL; C = 2619 � 106 � 153 spz mL–1; total and progressive motility were 89.0 � 2.1% and 66.9 � 2.1%, respectively. Percentages of head abnormalities were 4.8 � 0.5; midpiece: 3.8 � 0.7; tail: 4.7 � 1.0; cytoplasmic droplets: 8.3 � 0.7; intact acrosome: 91.8 � 0.6; and membrane integrity: 49.2 � 2.1. At 4�C, the % of total motile spz was 62.6 � 1.6, and the post-thaw survival rate was 46.3 � 1.5. There were only individual differences (P < 0.001) between bucks on sperm concentration, head abnormalities, and cytoplasmic droplets. In conclusion, our results indicate that semen quality is related to each individual animal and that electro-ejaculation allows collection of semen of satisfactory quality to use as fresh and for cryopreservation. However, the validity of our results for possible future sperm banking of endangered Bermeya goats semen must be confirmed by field trials.

The purpose of this study was to examine sperm quality after cryopreservation of ejaculates collected as a bulk sample, which is routinely part of semen collection, and to compare this quality with the sperm-rich fraction in boars. Ejaculates were collected as sperm-rich fractions (SRF) and bulk samples (BE) using a gloved-hand technique. Fresh semen quality in terms of semen volume, sperm concentration, total sperm motility and pH were conventionally evaluated. Then, semen was cryopreserved using the liquid nitrogen vapour method. The post-thaw sperm quality was evaluated by assessing sperm motility, live sperm with normal apical ridge and high mitochondrial energy status, lipid peroxidation was evaluated using CASA and fluorescent multiple staining and MDA levels were determined using a spectrophotometer, respectively. In terms of fresh semen quality, sperm motility in fresh semen did not differ significantly between the two groups. The treatment with the greater mean volume (BE; P &lt; 0.05) had a lower mean sperm concentration (P &lt; 0.05); meanwhile, the mean ejaculate pH collected as BE was more basic compared with SRF (P &lt; 0.05). However, there were no significant post-thaw quality changes between sperm-rich fractions and bulk samples of semen. In conclusion, ejaculates can be collected as bulk samples without the need to classify fractions for boar semen cryopreservation.

This study was carried out in Artificial Insemination Center of Iraq to revealed FMD disease effect on some seminal attributer parameters of 14 imported Holstein bulls divided to three groups according to different reproductive efficiency (four High, five medium and five weak). Results showed that FMD disease had significant (P < 0.05) adverse effect on most seminal attributer parameters, mass, individual motility and sperm concentration / ml during post disease in first of two, four, all months of high, medium and weak semen quality bulls respectively .but semen volume didn’t influenced significantly with this disease. So semen collection should be suspended until resume normal fertility of sperm, after two, four month of high and medium bulls respectively, and must be revealed weak bulls when disease happen to avoid the failure of conception from artificial insemination and there is no economic benefit to use or keep weak bulls

OBJECTIVE: To assess differences in semen quality between similar populations from Denmark and Finland. DESIGN: Comparison of semen quality between 221 Finnish men (of whom 115 had no proven fertility) and 411 Danish men with no proven fertility in two follow-up studies among normal couples trying to conceive. METHODS: In Finland male partners of couples without experienced infertility attempting to conceive were recruited through advertisements in local newspapers from 1984 to 1986. From 1992 to 1995 Danish men who lived with a partner and who had not attempted to achieve a pregnancy previously were recruited through their union when they discontinued birth control. All semen analyses were performed in accordance with the World Health Organization guidelines. RESULTS: Median sperm concentration, total sperm count and the percentage of morphologically normal spermatozoa were significantly higher among the Finnish men without proven fertility (104.0 million/ml, 304.0 million and 58% respectively) compared with the Danish men (53.0 million/ml, 140.8 million, and 41% respectively). Sperm concentration was 105.7% (95% confidence interval (CI) 58.1%-167.6%) and total sperm count was 127.4% (95% CI 71.4%-201.6%) higher among Finnish men without proven fertility than among Danish men after control for confounders. CONCLUSIONS: Some, but hardly all, of the observed difference in semen quality may be explained by differences in recruitment procedures, selection of the men and by methodological differences in semen analysis between the two countries. Also a birth cohort effect may explain some of the differences between countries as the Finnish men were recruited 11 years before the Danish men. Therefore, follow-up studies with identical recruitment and selection of men from the two countries are needed.
