Summary The chicken major histocompatibility complex (MHC), the B complex, is being intensively analysed at the DNA level. To further probe the molecular structure of chicken MHC class II genes, cDNA clones coding for chicken MHC class II (B-L) p cha

High molecular weight DNA was extracted from sperm from chickens of 14 inbred lines. The DNA was digested with each of four restriction enzymes (Pvu II, Hind III, Bgl II, and Bam HI), electrophoresed for 18 or 45 h, blotted onto nitrocellulose, and h

1. The purpose of the experiment was to evaluate the use of food consumption records in selection to improve layer-type chickens. 2. Twelve subpopulations of Leghorns, including 5878 tested birds, were used in a selection experiment which lasted 5 ge

1. Genetic mechanisms of resistance to disease in 1930 pullets and 296 cockerels were investigated by using a Leghorn line (G), a heavy-breed line (H), and their reciprocal crosses G x H and H x G plus two synthetic lines, GnH and HnG which were segr

In part A of this study, six genotypes involving all combinations of the B blood group haplotypes, B1 , B12, and B15, in White Leghorn inbred line HN were compared for resistance to Rous sarcoma virus (RSV)-induced tumors. Results confirm the finding

Chickens from the Iowa State S1 White Leghorn line, selected for characteristics of Ea-B serotype, humoral immune response to glutamic acid-alanine-tyrosine (Ir-GAT), and response to Rous sarcoma virus (RSV)-induced tumors, were evaluated for genetic

Two kinds of selection programs were compared. The first uses information on body weight (BW), egg mass output (EM), and individual bird feed consumption records (FC) to form a conventional single-stage selection index computed on all breeder candida

The growth of an animal part (y) relative to the whole (x), is expressed in terms of an exponential equation, y = alpha x beta, where alpha and beta are growth constants. For the present study x is body weight and y is shank length determined for 10

The value of individual feed consumption records to improve net income through genetic gain was investigated in an egg-type breeding operation. Genetic and phenotype parameters were estimated for body weight, egg mass and feed consumption on 788 laye
