Summary
Ewe lambs fed lucerne for nine months showed reproductive tract damage and heavier mammary glands with secretory activity compared to controls on ryegrass. This study highlights lucerne
Area of Science:
- Veterinary Pathology
- Animal Science
- Reproductive Biology
Background:
- Lucerne (Medicago sativa) is a common forage crop.
- Dietary components can influence animal health and reproductive physiology.
- Understanding forage effects is crucial for livestock management.
Purpose of the Study:
- To investigate the histopathological effects of lucerne consumption on the reproductive organs and mammary glands of ewe lambs.
- To compare these effects against a control group fed ryegrass.
Main Methods:
- Histopathological examination of reproductive tissues (uterus, cervix, vagina) and mammary glands.
- Comparative study involving 10 ewe lambs on lucerne and 10 controls on ryegrass over nine months.
Main Results:
- Lucerne-fed lambs exhibited uterine periglandular edema and subacute endometritis.
- Cervical changes included secretory-cell hyperplasia with neutral mucopolysaccharides.
- Vaginal tissues showed hyperkeratinization and colpitis.
- Mammary glands were significantly heavier and demonstrated secretory activity in lucerne-fed lambs.
Conclusions:
- Prolonged lucerne consumption induces significant histopathological changes in the ewe lamb reproductive tract.
- Lucerne feeding also promotes mammary gland development and secretory activity.
- These findings suggest potential implications for reproductive health and productivity in sheep.
