20 Muscovy ducks in single cages were inseminated at 14-day intervals over a period of 16 wk. The av. egg fertility was 63.2%, ranging from 35.1 to 84.3% for individual birds. The av. embryo mortality was 8.8%, ranging from 4.3% on day 8 after insemination to 25.0% on day 14. Laying intensity had...

Abstract

For 293 ejaculates, semen volume averaged 1.04 ml, sperm concentration (X 106/ mu l) 1.69, sperm motility 57.5%, methylene blue reduction time 5.1 min, the percentage of abnormal spermatozoa 18.0, and pH 7.1. Insemination with 0.05 or 0.10 ml semen at 3- to 4-day intervals resulted in egg fertility ...
