为了建立一种基于新生猪体重增加估算初乳摄入量的方法，进行了三项试验。第一次试验涉及33个小猪,人工营养的母猪初乳和定期重25 h。初乳摄入相关的回归方程g (CI)出生体重(公斤)采办,重量在CI估计在公斤(BW),初次吸年龄(t (FS)的最小值)和持续时间的初乳摄入(t分和17 h小于或等于t小于或等于25 h)成立一个根均方误差等于33 g。用另外15头瓶饲仔猪的第二组数据对该方程进行了评估（试验2）。实测值与预测值非常接近（R-2 = 0.90）。第三项试验比较了导管母猪饲养和奶瓶喂养仔猪初乳摄取量估算值与先前公式或与氧化氘稀释法的比较。=每组12人)。该公式低估了这些仔猪的初乳摄入量，可能是由于先前的手术。然而，饲喂方式（奶瓶喂养与母猪饲养）对初乳摄取量与增重之间的关系没有影响。因此，在瓶饲仔猪中建立的公式可以应用于母猪饲养的仔猪。
Three trials were performed in order to establish a method of estimation of colostrum intake based on weight gain in newborn pigs. The first trial involved 33 piglets, bottle-fed with sow colostrum and weighed regularly for 25 h. A regression equation relating colostrum intake (CI in g) to birth weight (BWB in kg), weight at CI estimation (BW in kg), age at first suck (t(FS) in min) and duration of colostrum intake (t in min and with 17 h less than or equal to t less than or equal to 25 h) was established with a root mean-square error equal to 33 g. This equation was evaluated with a second data set using 15 further bottle-fed piglets (trial 2). Measured and predicted values were very close (R-2 = 0.90). The third trial compared colostrum intake estimated either with the previous equation or with the deuterium oxide dilution method in catheterized sow-reared or bottle-fed piglets ( no. = 12 per group). The equation underestimated colostrum intake of those piglets, probably due to prior surgery. However, the feeding method (bottle-feeding v. sow-rearing) had no effect on the relationship between weight gain and colostrum intake. Therefore, the equation established in bottle- fed piglets may be applied to sow-reared piglets.
