The RJ administration resulted in a significant reduction in oxidative markers such as MDA, H2O2, and NO, and an increase in TAC and CAT compared to the RJ0 group (p <0.01) in raw and post-thawed semen. In cryopreserved semen, the progressive motility, viability, and membrane function were significantly higher in all RJ-treated rams (p <0.01). The majority of sperm parameters, including progressive motility, distance average path, distance curve linear, distance straight line, average path velocity, curve linear velocity, and straight line velocity, were superior in the RJ groups compared to the untreated ram group (p <0.05). The orally administered RJ affected both sperm membrane and acrosome status significantly (p <0.01). Specifically, RJ supplementation significantly increased the proportion of viable spermatozoa with intact acrosomes, while concurrently reducing the percentages of both viable acrosome-damaged and non-viable acrosome-intact cells across all treatment groups (p <0.05). Sperm viability was significantly higher in the RJ250 and RJ500 groups compared to the RJ0 treatment (p < 0.001). Furthermore, RJ administration significantly decreased the incidence of early apoptotic, late apoptotic, and necrotic spermatozoa relative to the RJ0 group (p < 0.05). Regarding the microbial profile, both coliform and total bacterial counts in post-thawed semen were significantly lower in RJ-treated rams than in the RJ0 group (p < 0.05). Oral administration of RJ significantly preserved testicular histoarchitecture, characterized by the maintenance of seminiferous tubule integrity, an increased population of spermatogonia, and the distinct presence of intraluminal spermatozoa. Furthermore, RJ treatment maintained the critical ultrastructural components of the spermatozoa, including the structural integrity of the plasma membrane, the mitochondrial sheath, and the nucleus. Collectively, these findings suggest that oral RJ supplementation enhances reproductive performance and post-thaw semen quality in rams, likely mediated by its potent antioxidant properties and its protective role during the cryopreservation process.]]> https://www.frontiersin.org/articles/10.3389/fanim.2026.1814529 https://www.frontiersin.org/articles/10.3389/fanim.2026.1814529 2026-05-11T00:00:00Z Original Research Colten W.

However, increasing dietary guarana levels significantly affected growth performance, with linear reductions in ADFI and ADG (p ≤ 0.05), while the G/F ratio increased linearly. Quadratic responses were observed for hot carcass yield, cold carcass yield, loin eye area, and fat-to-meat ratio. These results indicate that guarana supplementation influences the growth performance and carcass characteristics of finishing pigs, but does not improve the overall productive performance under the conditions evaluated.]]> https://www.frontiersin.org/articles/10.3389/fanim.2026.1790504 https://www.frontiersin.org/articles/10.3389/fanim.2026.1790504 2026-05-05T00:00:00Z Original Research Whad FayedMervat A.
