Concept:Malnutrition-related diseases arise from dietary deficiency or imbalance, whereas infectious diseases occur independently of nutrition.
Explanation:Aspergillosis is a fungal infection caused by the
Aspergillus fungus, usually picked up from contaminated feed or litter.
It does not result from poor feeding or lack of nutrients.
Acidosis is a metabolic disorder caused by overeating grains, which leads to excess acid in the rumen.
Milk fever is a metabolic condition linked to severe calcium (
Ca) deficiency around the time of calving.
Rickets develops in young animals due to inadequate calcium (
Ca), phosphorus (
P), or vitamin D in the diet.
Hence, acidosis, milk fever, and rickets are dietary-related, while aspergillosis is not.
