Muscle adenine nucleotide degradation in the thoroughbred horse as a consequence of racing

Abstract: 1. 1. Adenine nucleotide (AN) degradation as a result of racing was examined in thoroughbred horses. 2. 2. Muscle ATP loss in some horses was as great as 50% and in all cases was matched by an equivalent increase in IMP. Mean post-exercise IMP contents varied little with race distance but individual values varied considerably within each race. 3. 3. Results demonstrate that significant AN degradation occurs in muscle as a result of racing and further indicates that the onset of this process is associated with the fall in muscle pH to values probably less than 6.8.

Perspectives on antimicrobial resistance in livestock and livestock products in ASEAN countries.

Abstract: Antimicrobial resistance (AMR) in bacteria, particularly in foodborne pathogens, has increasingly become apparent in most parts of the world including ASEAN countries, creating great impact on economy, human and animal health and international food trade. The tendency of bacterial pathogens to become multidrug resistant (MDR) is the most serious concern in AMR. The ASEAN Economic Community (AEC) will be fully established in 2015 and ASEAN cooperation has acknowledged the significance of food safety, of which AMR is one of the major concerns. There is a need for all ASEAN nations to harmonize its AMR monitoring and surveillance programmes in order to strengthen the control and institute prevention strategies in the region. Currently, public health systems dealing with monitoring and control in ASEAN countries are still highly diverse and require a unifying action. National monitoring and control programmes for AMR have not been successfully established in most ASEAN countries and a regional-cooperative programme has yet to be set in place. Therefore, a review of current AMR situations in ASEAN member states shall be useful for future development and establishment of monitoring and control programmes within the region.

Anti-oxidative status and semen quality during cooled storage in stallions.

Abstract: Activity of the anti-oxidative enzymes glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT), content of thiobarbituric acid reactive substances (TBARS) and SH-groups were determined in native stallion semen (n = 8 stallions). Semen was then diluted in Kenney extender, EquiPro((R)) extender either with or without addition of N-acetyl cysteine or phosphate-buffered saline (PBS) and stored for 72 h at 5 degrees C. Correlations between initial activity of enzymes and development of semen motility and membrane integrity were calculated. Activities of GSH-Px, SOD and CAT immediately after semen collections were 10.0 +/- 0.6 picokatals, 0.40 +/- 0.03 SOD units and 0.70 +/- 0.05 nanokatals/10(6) spermatozoa respectively. TBARS content was 0.06 +/- 0.01 nmol and SH-group content 1.7 +/- 0.5 mmol/10(6) spermatozoa. The loss of motile spermatozoa during storage did not differ between extenders. N-acetyl cysteine had no effect on semen motility and membrane integrity. The loss in membrane-intact spermatozoa was highest (P < 0.05) in semen diluted in PBS. Motility and membrane integrity after addition of extender were positively correlated with GSH-Px and CAT, indicating that anti-oxidative mechanisms contribute to the initial high percentage of motile and membrane-intact spermatozoa. However, in these samples the decrease in semen quality was most pronounced. No correlations existed between initial activity of anti-oxidative enzymes, peroxidation products and semen quality during storage. This indicates that once extender has been added, peroxidative damage to sperm membranes is not the predominant cause of losses in semen quality.
