| upper-normal prediction limits of lymphocyte counts for cattle not infected with bovine leukemia virus. | a study was conducted to develop valid estimates of lymphocyte count (lc; cells per microliter) of individual, clinically normal dairy cattle. estimated weighted regression was used on repeated measures of individual lc to examine 6 models predicting lc as a function of age in cattle not infected with bovine leukemia virus. the generalized growth curve model of analysis of variance was used to estimate intercepts, slopes, and prediction limits for the models and to compare the lc-to-age relation ... | 1990 | 2156474 |
