The objective was to estimate the genetic parameters of serum total protein concentration in newborn calves (calfSTP) and post parturient dairy cows (cowSTP). The study included 1013 calves and 989 cows from 10 dairy farms. Calf blood samples were collected 24-48 h after parturition while cow blood and colostrum samples were collected in the first 24 h after calving.

Increasing knowledge of their hematologic profiles during this period could benefit both veterinary clinical pathologists and bovine practitioners. The objectives of this study were: (a) to establish period-specific RIs for Holstein dairy cows and (b) to assess the potential simultaneous effect of several factors on hematology parameters.

- The study examined colostrum composition and yield in 1,017 healthy Holstein cows across 10 farms, focusing on factors that influence these characteristics.
- The average colostrum content for fat, protein, lactose, and total solids (TS) was found to be 6.37%, 17.83%, 2.15%, and 25.80%, respectively, with parity affecting protein and TS positively while reducing fat content.
- Additionally, the timing of colostrum collection post-calving and overall yield negatively impacted protein and TS content, emphasizing the importance of fat assessment for meeting the energy needs of newborns.
