Examples

  • Birds of prey are especially susceptible to DDT poisoning, since it accumulates at the top of the food chain and reduces the hatchability of eggs.

  • Other efforts are needed to increase the hatchability of eggs under natural conditions (under guinea hens or surrogate mothers), and to identify the best lighting regimes (both sexual maturity and rate of lay are influenced by changes in daylength).

  • However, second-year egg production is normally less than half the first year's, and fertility and hatchability fall sharply after birds reach 6 months of age, even though egg and sperm production continue.

    5 Chicken 1991

  • However, for reproduction about twice that is needed to allow for mating rituals. 3 If properly mated, high fertility rates and good egg hatchability can be expected.

    5 Chicken 1991

  • There is a need for more information on growth rate, health, egg production, feed conversion, body weight, carcass yield, laying intensity, fertility, hatchability, and egg weight - especially under free-ranging conditions.

    5 Chicken 1991

  • This improves egg size and hatchability and reduces early mortality.

    5 Chicken 1991

  • From their eggs 234 chicks were produced; the average percentage of fertility of the eggs was diminished but the average percentage of hatchability of fertile eggs was increased.

  • How could we know what the fertility and hatchability was going to be, or sex ratio?
