A total of 133 observations on mean daily mass gains from 19 calves reared on either whole milk (control) or preserved colostrum (treatment) were estimated. The control group had a total of 104 observations computed, while the treatment group had a total of 29 observations. There was no significant difference in the overall mean daily mass gains between the treatment and control groups which were 0.2257 and 0.3607 kg, respectively (P < 0.1). Partial budgeting analysis estimated that with an annual calf crop of 80 calves, the use of preserved colostrum would result in a direct saving of an estimated US$1,800 per year for the farm.
对19头用全脂牛奶（对照组）或保存初乳（处理组）饲养的犊牛的平均日增重进行了总计133次观测。对照组共计算了104次观测值，而处理组共有29次观测值。处理组和对照组的总体平均日增重分别为0.2257千克和0.3607千克，两者之间无显著差异（P < 0.1）。局部预算分析估计，若每年有80头犊牛出栏，使用保存初乳将为农场每年直接节省约1800美元。
