The microscopic point method of botanical analysis gave a satisfactory estimate of spe-
cies composition on a percent dry-weight bais in this two component mixed forage sample collected by the esophageal-fistula technique. The Y = X relationship was nearly as ac-
curate as a linear, quadratic, or cubic regression equation through the origin for thiss par-
ticular two-component mixture where Y = percent weight and X = percent points. Even
though there were no significant differences among observes, thre was a significant wei-
ght x man interaction. Two of the observers were more consistent and required one-half
as many points as the other two for the same degree of accuracy. Multiple comparison
test that estimates in one and possibly two weight groups were signifiantly different from
the other groups. Four hundred points estimated percent dry matter at 90% confidence
limit to within 20% of the mean if the weight is 16 to 30%, to within 10% of the mean bet-
ween 30 and 50% weight, and to within 5% of the mean from 50 to 95% weight. |
