|Sample (as-fed, warm||Coliform (cfu/ml)||Total Plate (cfu/mL||My comment|
|1. Heat-treated in Perfect Udder bags||3||16,000||Okay to feed|
|2. Heat-treated in a batch pastuerizer||10||4,000||Okay to feed|
|3. Fresh frozen in Perfect Udder bags||6,500||400,000||Marginal|
|4. Fresh refrigerated, PU bags||65,000||3,000,000||Bacterial soup|
Heat treating did not change the antibody concentration in the colostrum - all the samples tested between 77 to 80 grams per liter. We often use 50g/l as the dividing line between good and poor quality colostrum. These 59 pound calves received 4 quarts of this colostrum so their antibody intake was over 290 total grams at first feeding.
