Abstract
I. The Biology of Fowl Sperm.
1. The effect of testis hormone on the preservation
of sperm life in the vas deferens
of the fowl. •
2. Functional changes in fowl sperm during their
passage through the excurrent ducts of the
male. •
3. Fowl sperm immobilization by a temperature -
media interaction and its biological significance. •
4. The effect of dilution and density on the
fertilizing capacity of fowl sperm suspensions. •
5. The technique and errors involved in counting
fowl sperm with the haemacytometer. •
6. Motility and fertilizing capacities of fowl
sperm in the excretory ducts. •
7. The preparation of avian sperm smears for
microscopy. • •
II. The Inheritance of Egg Production in the Dourest
Fowl
8. General considerations. •
9. Increases in production, their extent and
characteristics with a discussion of causal
factors. •
10. Differences in transmitting ability of dams
and the degree of dam- daughter correlation. •
11. Reliability of progeny tests of sires. •
12. Relation of production to mortality. • •
III. Studies on Egg Quality.
13. Effect of heredity on interior egg quality
and shell composition. •
14, Correlations between certain fresh and storage
measurements in egg yolk and white. •
15. method of measuring the strength of the
yolk membrane.
