The Dean of the College of Agriculture chaired a committee for the defense of a master’s thesis at our college, which focused on the effects of glutathione injections on the characteristics of semen in local goats during the summer season.

The Dean of the College of Agriculture at the University of Diyala, Professor Dr. Raed Ibrahim Khalil, chaired the committee for the defense of a master’s thesis titled “The Effect of Glutathione Injections on the Characteristics of Semen in Local Goats During the Summer.”

The study, presented by the student Mohammed Hamid Saleh, aimed to investigate the impact of glutathione on semen characteristics in local goats by examining changes in the following parameters: the physical properties of the semen, levels of malondialdehyde compound, and concentrations of AST and ALT enzymes in seminal plasma. Additionally, the study evaluated biochemical blood traits, such as testosterone hormone levels and malondialdehyde compound in blood plasma, along with the dimensions of the testis and epididymis.

The study arrived at several conclusions, including that weekly injections of 15 and 30 mg/kg of glutathione in male local goats during the off-breeding season resulted in:

• Improved semen characteristics outside the breeding season,

• Elevated testosterone levels outside the breeding season,

• Increased dimensions of the epididymis and testis, contributing to enhanced reproductive efficiency in goats.

The study recommends:

• Using 30 mg of glutathione to stimulate sexual activity in male local goats during the summer,

• Combining glutathione with other antioxidants to explore its effect on semen characteristics,

• Conducting future research to assess the impact of glutathione injections in female goats outside the breeding season to determine its influence on egg production.
