Further Studies in Tissue Homotransplantation in Cattle
T H E work which forms the subject-matter of this communication is mainly complementary to that reported upon previously (see Anderson, Billingham, Lampkin, & Medawar, 1951; Billingham, Lampkin, Medawar, & Williams, 1952). It may be recalled that these transplantation studies were initiated in the mistaken belief that the oneor two-egg origin of twins in cattle could be established unequivocall...

متن کاملFurther Studies on the Ophthalmo-tuberculin Reaction in Cattle
Our conclusions differ in a few points from those of our first work on this subject. We are able to sum up our observations in this series of experiments as follows: 1. The ophthalmo-tuberculin test is of limited value in the diagnosis of tuberculosis in cattle. In some cases the reaction is very slight (hyperaemia). In others more pronounced congestion with profuse exudates are noted. Accuracy...
متن کاملGenetic parameters for sex-specific traits in beef cattle.
Data from 3,593 beef heifers and 4,079 of their steer paternal half-sibs were used to estimate genetic parameters of and among female growth and reproductive traits and male carcass traits. Estimates of heritability for adjusted 205-d weight, adjusted 365-d weight, age at puberty, calving rate, and calving difficulty measured on females were .16, .38, .47, .19, and .18, respectively; estimates ...
