Developmental stability in stocks of White Leghorn chickens.
The degree of asymmetry in bilateral morphological characters may reflect genetic and environmental stressors. Shank length and diameter, weight and length of the first primary wing feather, and distance between the junction of upper and lower mandibles and auditory canal (face length) were used to classify bilateral types and measure relative asymmetry (RA) in six genetic stocks. The stocks we...
متن کاملCharacterization of a spontaneous disease of white leghorn chickens resembling progressive systemic sclerosis (scleroderma)
University of California, Davis (UCD) line 200 White Leghorn Chickens spontaneously develop a syndrome that has many analogous features to human progressive systemic sclerosis. This syndrome is characterized by progressive involution of comb, dermal fibrosis, and distal polyarthritis. These three features occur within 6 wk after hatching, and are accompanied by a 40% mortality as a result of va...
متن کاملTissue tropism and bursal transformation ability of subgroup J avian leukosis virus in White Leghorn chickens.
In Experiment 1, a monoclonal antibody against the envelope glycoprotein (gp85) of subgroup J avian leukosis virus (ALV-J) was used to study the distribution of ALV-J in various tissues of White Leghorn chickens inoculated as embryos with the strain ADOL-Hcl of ALV-J. At 2 and 6 wk of age, various tissues from infected and control uninfected chickens were tested for the presence of ALV-J gp85 b...
متن کاملPurification of chicken carbonic anhydrase isozyme-III (CA-III) and its measurement in White Leghorn chickens
BACKGROUND The developmental profile of chicken carbonic anhydrase-III (CA-III) blood levels has not been previously determined or reported. We isolated CA-III from chicken muscle and investigated age-related changes in the levels of CA-III in blood. METHODS CA-III was purified from chicken muscle. The levels of CA-III in plasma and erythrocytes from 278 female chickens (aged 1-93 weeks) and ...
متن کاملChromosomal localization of three endogenous retrovirus loci associated with virus production in White Leghorn chickens.
Proposed mechanisms for the generation of endogenous retrovirus loci have been examined by determining the chromosomal distribution of these loci by means of in situ hybridization. Unlike the clustering on chromosome 1 of five endogenous retrovirus loci associated with the gs- chf- phenotype A. Tereba and S. M. Astrin, submitted for publication), three loci associated with endogenous retrovirus...
