This study aimed to compare the ability of sperm chromatin structure assay (SCSA ) and Sperm-Ovis-Halomax to detect DNA fragmentation in frozen-thawed ram spermatozoa incubated under capacitating conditions in synthetic oviductal fluid (SOF) supplemented with oestrous sheep serum (SOF-ESS) at multiple time points (0-240 min). Incubation in SOF-ESS had no significant effects on SCSA parameters while the percentage of spermatozoa with fragmented DNA measured by Sperm-Ovis-Halomax increased after 180 min of incubation. In addition, no correlation or agreement was found between the techniques, suggesting that SCSA and Sperm-Ovis-Halomax may quantify different types of DNA damage in ram spermatozoa under these experimental conditions.

Graphene oxide (GO) has been extensively studied for its diverse biomedical applications, including drug delivery, imaging, and tissue engineering. Silymarin, as a flavonoid complex derived from the milk thistle plant, has recently shown potential health benefits, particularly concerning reproductive health. This study aims to evaluate the effects of GO and silymarin supplementation, both individually and in combination, on the characteristics of frozen-thawed ram sperm.

Phytochemicals have been effectively used to enhance the growth and productivity of farm animals, while the potential roles of essential oils and their nano-emulsions are limited. This plan was proposed to investigate the impacts of orally administered moringa oil (MO) or its nano-emulsion (NMO) on the growth, physiological response, blood health, semen attributes, and sperm antioxidant-related genes in rams. A total of 15 growing Rahmani rams were enrolled in this study and allotted into three groups.

Current study was aimed to assess the β-cyclodextrin (βCD) and methyl-β-cyclodextrin (MβCD) on delivery of cholesterol, and substitution of fructose and glycerol with trehalose on the ram semen cryosurvival. Samples were collected, diluted with Tris-citric acid-LDL extender, pooled, and used. In experiment I, βCD and MβCD carriers were used and compared to deliver the cholesterol (at 0, 0.
