Abstract

The quality of fresh and frozen semen as well as the potential to produce frozen semen, vary considerably between individual animals and cattle breeds. This study aimed to analyze the quality of fresh and frozen semen in Aceh cattle and calculate the potential production of frozen semen in Aceh bulls over 1 year. This study used primary data on the quality of fresh and frozen semen from five Aceh cattle and obtained secondary data from artificial insemination centers in Lembang and Singosari in 2022. Semen samples were collected weekly, and the quality of fresh and frozen semen samples were evaluated. The data were analyzed using a one-way analysis of variance at 95% significance level, followed by Tukey’s test. The results revealed differences in semen volume and pH. Based on microscopic characteristics, the semen samples from different bulls exhibited no discernible differences in mass movement, sperm motility, viability, morphology, and plasma membrane integrity, except for sperm concentration and acrosomal integrity. Bull 211605 exhibited the highest sperm concentration. Furthermore, the frozen semen samples from Aceh cattle showed no significant differences in viability, plasma membrane integrity, morphology, and acrosomal integrity. The total sperm motility of bull 211710 was higher than that of the other bulls. The highest progressive motility was observed in bulls 211710 and 211605, and the highest intact DNA was detected in bulls 211710 and 211605. The results of this study demonstrated that the quality of fresh and frozen semen in Aceh cattle is distinct, and the potential frozen semen production of Aceh cattle is estimated to range from 3,382 ± 1810 to 11,399 ± 2658 straws/year.

Abstract

This study examined the differences in sperm quality and metabolite profiles among X and Y sperm in Friesian Holstein bulls. It also tried to find specific metabolites that can help improve the accuracy of sexed semen use in humid tropical dairy farms. Semen samples from five bulls were separated by sex and tested for movement, live sperm count, shape, and membrane and acrosome health. The tests used Computer-Assisted Sperm Analysis (CASA) and regular microscope checks. Metabolite analysis was performed using LC-HRMS, followed by various statistical tests, pathway checks, and ROC curve analysis. The outcomes showed that X sperm had better movement and acrosome health, while Y sperm had stronger membranes, fewer shape problems, and moved faster. The untargeted metabolite study showed clear differences between the two groups. X sperm had more identified metabolites and greater average levels. The crucial metabolites found more in X sperm were D-(−)-fructose, L-(+)-lactic acid, and sn-glycero-3-phosphocholine. Meanwhile, Y sperm had greater levels of acetyl-L-carnitine. The pathway analysis showed that X sperm primarily utilized carbohydrate and fat processing through glycolysis and phosphocholine pathways to maintain their movement and membrane integrity. On the other hand, Y sperm mainly use a carnitine-based energy pathway to support their faster and straighter movement. The identified metabolites can serve as reliable biomarkers to aid in laboratory quality control checks and enhance the quality of semen extenders. This outcome gives a good way to make sexed semen more stable and reliable in tropical dairy farming conditions.
