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...

Electrocardiograms and related variables of dwarf beef cattle

Creator:: Pinjani, Moti, 1939-
Abstract:: Electrocardiograms from 12 compressed male (CM), 16 compressed female (CF), ten synthetic compressed female (SCF), nine brachycephalic female (BF), and 15 dolichocephalic female (DF) dwarfs from Davis, California, taken in the scapular lead S-II (prescapular position positive and right forelimb negative) were analyzed, The data on dwarf electrocardiograms were compared...

Genetic polymorphism of sheep hemoglobin

Creator:: Templeton, Joe Wayne, 1941-
Abstract:: Five breeds of sheep (Columbia, Targhee, Rambouillet, Lincoln, and Suffolk) were found to possess two hemoglobin types (Hb. A and Hb. B) when their hemoglobins were examined by disc gel electrophoresis. The hemoglobin alleles proved to be co-dominant. Three of the breeds (Columbia, Targhee, and Rambouillet) were maintained at altitudes...

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...

Performance of three inbred lines of Herford cattle and their linecrosses

Creator:: Munji, Marcus Tebid
Abstract:: Three inbred and relatively unrelated lines of Hereford cattle (1. Lionheart, 2. Prince, and 3. David) developed at the Corvallis branch of the Oregon Agricultural Experiment Station as part of the W-1 project of the Western States were crossed annually from 1963 through 1965 inclusive. Data on 137 inbred and...

Serum T₄ and liver NAD and NADP as performance indicators in beef cattle

Creator:: Brokaw, Bryan Edward
Abstract:: The relationships of serum T₄ (thyroxine) levels and liver nicotinamide nucleotide coenzyme (NAD and NADP) levels with production of traits of beef cattle were investigated at both weaning (182 kg) and following performance testing (363 kg). In addition, the value of these parameters as selection criteria for improved performance was...

The relationship between x-ray induced teratogeny and chromosome aberrations in golden hamster embryos

Creator:: Jones, William Elvin
Abstract:: The relationship between x-ray induced chromosome aberrations and x-ray induced embryonic abnormalities was studied. Golden hamsters were irradiated during four stages of gestation: the blastocyst stage, 4.5 days post-copulation; the primitive streak stage, 6.5 days post-copulation; the organogenesis stage, 9.5 days post-copulation; and the period of fetal growth, 11.5 days...

The comparison of two methods of evaluating inheritance of milk production of dairy sires

Creator:: Srinives, Supote
Abstract:: The production records used were all converted to a comparable based, 305 day lactation period, two times a day milking, and mature equivalent (305 days-2-x-ME) of 71 cows from four Holstein bulls and 59 cows from four Jersey bulls were used for the study. The Equal Parent Index, Regression Index...
