Recipients
Selection
|
Sanity Management Vaccination and control with BoHV-1, BVDV, Leptospira spp., and Neospora ssp
|
Nutritional Management Select recipients with BCS above 2.5 to 4 points (scale 1-5). |
CL Classification The presence of CL is required. CL perfusion is more important than diameter/dimensions. |
