Figure 2:
Bar graph showing the results of refractometry readings for 422 calves aged 0-8 days on 116 southern Ontario dairy farms. Calf serum total protein levels below 5.2 g/dL are considered to have received inadequate immune protection from colostrum. Approximately 35% of calves are shown to have received inadequate immune protection.
