- Milk fever in dairy cows: A review of pathophysiology and control principles (182 citations)
- Hypocalcemia in dairy cows: meta-analysis and dietary cation anion difference theory revisited. (174 citations)
What are the main themes of his work throughout his whole career to date?
Ian J. Lean spends much of his time researching Animal science, Dairy cattle, Lactation, Ice calving and Dry matter.
His Animal science research includes themes of Rumen, Endocrinology and Internal medicine.
His study in Dairy cattle is interdisciplinary in nature, drawing from both Urea, Amino acid, Monensin, Meta-analysis and Milk production.
The Lactation study which covers Vitamin D and neurology that intersects with Vitamin.
His work carried out in the field of Ice calving brings together such families of science as Mastitis, Fertility, Urine and Estrous cycle.
His Dry matter study also includes
- Neutral Detergent Fiber most often made with reference to Food science,
- Silage which connect with Hay.
He most often published in these fields:
- Animal science (57.85%)
- Dairy cattle (33.06%)
- Lactation (29.75%)
What were the highlights of his more recent work (between 2017-2021)?
