Beef Cattle Fertility

The objective of this study was to determine factors of sperm structure that influence fertility within bulls. We hypothesized that as the mitochondrial sheath on the tail lengthens, the increased energy production of the sperm cell would impact bull fertility. In the results of this study, we found a positive correlation between the mitochondrial sheath length and the fertility rates of bulls, indicating that mitochondrial sheath structure influences fertility.
