Some genetic and environmental factors affecting weaning weights of lambs

Creator:: Dahmen, J. J. (Jerome John), 1919-
Abstract:: Eight purebred rams (four Suffolk and four Panama) previously selected as high and low on the basis of post-weaning performance feed test of 84 days were used each of three years. Each of the rams was mated to approximately 25 grade Panama ewes each year. One ram and 25 ewes...

Selection applied, response of traits and combining abilities of inbred lines of beef cattle

Creator:: Hoornbeek, Frank K. (Frank Kent), 1928-
Abstract:: The investigations reported are based on two studies; the first is concerned with the selection practiced for performance in one inbred Angus and three inbred Hereford lines of cattle, the realized responses, levels of inbreeding and associated performance, and heritabilities of the performance traits. Selection differentials for all performance traits...

Certain physiological and pharmacological effects of radiation on rabbits

Creator:: Wagelie, Edwin Gan
Abstract:: Data were taken, following irradiation exposure to 100r and 300r cumulative dose, on 89 rabbits of three breeds that vary greatly in body size. Hematological, intestinal motility, and ear vascularity examinations were performed. Least square estimates have been obtained and an analysis of variance has been conducted in order estimate...
