Article Synopsis
- The study compared two staining techniques, Diff-Quick and Spermac, to see how they affect the assessment of sperm morphology and influence infertility diagnoses.
- Results showed that while both methods clearly displayed sperm structures, Diff-Quick identified a higher percentage of normal spermatozoa compared to Spermac, which highlighted more midpiece abnormalities.
- The findings suggest that the choice of staining technique is crucial for accurate diagnoses of male infertility, indicating a need for further research on optimal methods.

This study was performed with the main objective of evaluating the effect of the combination of pelleting and monensin on fatty acids (FA) composition, the concentration of total polyphenols and flavonoids, and the oxidative stability of milk in cows fed a concentrate containing soybean seeds. Eight Holstein multiparous cows were distributed in a replicated Latin square design. The four supplement treatments consisted of the combination of two factors (pelleting and monensin) and one concentrate as follows: (1) unpelleted concentrate with no monensin (CO); (2) pelleted concentrate with no monensin (PE); (3) unpelleted concentrate with 96 mg of monensin/kg of dry matter, DM (MO); and (4) pelleted concentrate with 96 mg of monensin/kg of DM (PM).
