- Abstract
The study was carried out on a dairy farm in Castrolanda, in the county of Castro - PR. The management system is free stall, with 220 Holstein cows with RHA305 of 6,740 liters. Blood samples were collected from 18 pre-calving cows, 4 days before the expected date of calving; and on days 4, 7 and 12 postpartum, by means of coccygeal venipuncture, using SnapTest digital Ketovet®, constituting 72 samples, from February to May 2020. In 4 cows the BHB of whole blood was shown above the limit for subclinical ketosis on the fourth day after delivery and 17 presented above the limit on the seventh day, then declining mainly due to clinical interventions. The means and standard deviations were D -4: 0.89 ± 0.257061; D 4: 1.05 ± 0.283279; D 7: 1.81 ± 0.456131; and D 12: 1.19 ± 0.437762. The benefit of monitoring BHB was immediate clinical intervention, avoiding clinical ketosis and concomitant illnesses.
