Short communication: Low levels of colostral immunoglobulins in some dairy cows with placental retention.
A test with 27 Holstein cows divided in two groups was conducted to evaluate the effects of placental retention (PR) on the colostral components. Fat and total protein content were similar in both groups, but immunoglobulins in cows with PR (7.58+/-6.72 g/L) were significantly lower than in cows without PR (15.13+/-8.56 g/L). In contrast, casein levels were higher in cows with PR (38.61+/-17.05 g/L vs. 27.60+/-12.71 g/L) compared with cows without PR.
