Genetic correlations of abdominal fat with production traits of Leghorn hens based on inbred line averages.

Data from 16 inbred lines derived by three generations of full sib mating from a common outbred base population were used to estimate genetic correlations between body weight, abdominal fat content, follicle number, liver weight, egg weight and egg number using between-line variances and covariances. High genetic correlations were found between body weight, fat content and egg weight. Low genetic correlations were found between follicle number and all traits other than egg weights. Theoretical expectations and low correlations within lines led to the conclusion that environmental correlations among the traits considered were very low.

Differences in body fat of six inbred lines of white leghorns derived from a common base population.

Genetic differences in body fat, body weight, follicle number, and egg production were found among six inbred lines of White Leghorn hens derived from a common outbred base population. High positive genetic correlations of body fat with body weight were found between inbred lines as well as between inbred parents and line-cross progeny. Heterosis of fatness, body weight, egg production, egg weight, and liver weight were observed. Large follicles and liver weight were unaffected by inbreeding and crossing of lines.

Histocompatibility antigen transfer in utero: tolerance in progeny and sensitization in mother.

Subcellular antigens obtained from donor spleen and kidney were administered to pregnant rabbits treated with hyaluronidase. Partial immunological tolerance to the donor was thus induced in the fetuses during the adaptive phase. The duration of tolerance was proportional to the total dose of antigen administered to the mother. Maternal sensitization to the offspring was noted in all rabbits giving birth to partially tolerant progeny.
