[Dynamics of clinico-biochemical changes in sheep during magnesite loading]

Area of Science:

• Veterinary Medicine
• Animal Nutrition
• Environmental Toxicology

Context:

• Industrial byproducts like magnesite fly ash can contain high levels of minerals, including magnesium.
• Assessing the impact of such materials on livestock health is crucial for animal welfare and food safety.
• Sheep, particularly ewes, are sensitive indicators of dietary changes and potential toxicities.

Purpose:

• To investigate the clinical and biochemical effects of feeding magnesite fly ash to Improved Wallachian ewes.
• To monitor changes in feed intake, water consumption, and excrement consistency.
• To analyze hematological profiles, serum enzymes, and mineral element concentrations in response to magnesite fly ash administration.

Summary:

• Daily administration of magnesite fly ash (500 mg/kg live weight) to ewes resulted in decreased concentrate intake, increased water consumption, and diarrhea starting around day 15-20.
• Hematological parameters remained within physiological ranges, but alanine aminotransferase levels increased significantly.
• Magnesium concentrations markedly increased in blood serum, urine, and droppings, suggesting significant absorption and excretion of this mineral.

Impact:

• The study highlights the potential gastrointestinal and metabolic disturbances in sheep due to magnesite fly ash ingestion.
• Significant increases in serum magnesium indicate a high bioavailability and potential for magnesium toxicity or imbalances.
• Further research is needed to understand the complex interactions of other minerals present in fly ash and their long-term effects on sheep health.
