Abstract
Using 684 semi-official records made on the Univ. of Illinois herd, it was observed by sampling different parts of these records that testing only 3 times per yr. was more than 92% accurate as measured by the semi-official test. Production measured by tests taken twice during the lactation were 85-87% accurate.This publication has 6 references indexed in Scilit:
