Several environmental factors affect calf's health, including nutrition. Functional plasma proteins (FPP) fed to neonatal calves have been reported to improve performance and reduce fecal scores, medical treatments and mortality. However, research evaluating Lifeline Protect (colostrum supplement) (LP) and NutraPro (spray-dried plasma, NP) in a traditional California milk and housing program is limited. The objective was to evaluate a FPP program consisting of LP upon arrival and NP added to the milk feeding program for dairy calves during cold stress on performance, morbidity, and mortality. Milk fed to calves was a mixture of whole milk and milk replacer fortified to 14% solids. A step-down program was used so that d-56 calves were weaned. Holstein bull calves (n = 54) were sourced from 8 different dairies and transported to Fresno State University campus on January 2019. Calves were randomized to 1 of 2 feeding treatment groups based on dairy origin, serum total protein level and BW, and then housed in wooden, 3-hole calf hutches. Treatments groups consisted of a control milk program (CMP) using whole milk with added milk replacer to balance solids to 14% and the FPP program consisting of LP (50 g globulin/calf) upon arrival and thereafter using whole milk with 5% NP plus milk replacer to 14% solids. Weekly BW was recorded. Bottles were weighed before and after each feeding to determine milk intake. Daily grain consumption was recorded. Twice daily health and fecal scores were taken to evaluate morbidity. In the first 14 d, calves fed FP were heavier (P < 0.05: 44.8 vs. 43.5 kg) compared with CMP calves. By 56 d, FP calves were 74.5 kg vs 73.9 kg for calves fed CMP. Over the 8-week period, attitude score, average fecal score and number of medications per calf (7.3 vs. 12) was reduced (P < 0.05) for calves fed FPP compared with CMP. Survival was numerically increased for calves fed FPP (92%) vs CMP (80.8%). Calves fed FPP performed better and had less medication treatments, morbidity, and mortality compared with calves on CMP.
