Evaluation of commercial oral replacement formulas in healthy neonatal calves.


Effects of 5 commercial oral replacement formulas on hematologic and plasma biochemical values, body weight, and prevalence of diarrhea were studied in healthy neonatal calves. Products were fed according to manufacturers' recommendations beginning at 3 to 7 days of age for 3 days. Whole milk, diluted 1:1 with commercial formulas, was fed for 3 days thereafter. There were no consistently significant (P greater than 0.05) effects of commercial product feeding with time or by treatment, as compared with those in whole milk-fed controls, on the hematologic or biochemical values of PCV, leukocyte count, platelet count, or plasma K, Cl, glucose, and lactic acid concentrations. Plasma Na concentrations decreased significantly (P less than 0.05) with age in all groups. After 2 weeks, milk-fed calves had gained 2.09 +/- 0.96 kg, and calves fed all but 2 hypertonic energy-dense products 1 and 5 had significant (P less than 0.05) weight losses (up to 2.95 +/- 1.34 kg). Transition to a diet of whole milk and commercial product at one half each of their standard doses resulted in a significant (P less than 0.05) occurrence of diarrhea. Seemingly, such formulas should not be fed to healthy calves on a long term basis. The product with the lowest osmolal and caloric content was associated with the greatest weight loss.
