Animal Reproductive Physiology

⁻Study of sperm parameters (motility, morphology, viability) in ruminants (cattle, goats) and poultry (roosters, hens).

⁻Impact of environmental stressors (heat, pesticides, heavy metals) on male and female fertility.

• Veterinary Toxicology

⁻Effects of pesticide residues (glyphosate, neonicotinoids) and agricultural pollutants on animal health.

⁻Mechanisms of oxidative stress and hepatic detoxification in livestock.

• Nutrition and Stress Management in Livestock

⁻Use of natural antioxidants (local plants, vitamins C/E) to mitigate the effects of thermal or chemical stress.

⁻Optimization of feed rations to enhance animal resilience.

• Specific Expertise
• Methodologies:

⁻Sperm analysis (CASA: Computer-Assisted Sperm Analysis).

⁻Biochemical assays (antioxidant enzymes, malondialdehyde as a marker of oxidative stress).

⁻Histopathology of reproductive organs (testes, ovaries, etc.).

• Innovative Approaches:

⁻Use of phytotherapy (plant extracts such as moringa or ginger) to improve reproduction under environmental constraints.

⁻Ecotoxicology: Risk assessment of agricultural practices on livestock.

• Reproductive Biotechnologies:

⁻Artificial insemination (Ruminants and pigs)
