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.
研究了5种市售口服补液配方对健康新生犊牛血液学和血浆生化指标、体重及腹泻发生率的影响。从3至7日龄开始，按照制造商的建议投喂产品，持续3天。此后，投喂用市售配方按1:1稀释的全脂牛奶，持续3天。与全脂牛奶喂养的对照组相比，投喂市售产品对红细胞压积、白细胞计数、血小板计数或血浆钾、氯、葡萄糖和乳酸浓度等血液学或生化指标，在时间或处理方面均无持续显著（P大于0.05）的影响。所有组的血浆钠浓度均随年龄显著降低（P小于0.05）。2周后，牛奶喂养的犊牛体重增加了2.09±0.96千克，而除2种高渗能量密集型产品1和5外，投喂其他产品的犊牛体重显著减轻（P小于0.05）（减重高达2.95±1.34千克）。以标准剂量的一半投喂全脂牛奶和市售产品的混合日粮会导致腹泻显著（P小于0.05）发生。显然，这类配方不应长期投喂给健康犊牛。渗透压和热量含量最低的产品导致的体重减轻最大。
