Abstract

Fowl semen was diluted with 2 different glutamate-based diluents with 8% glycerol and was frozen in pellets. When the semen was used for shallow, vaginal insemination using 180 × 106 spermatozoa per insemination dose, the overall egg fertility was 19.4% vs. 27.7% for deep, vaginal insemination of...

Zur künstlichen Besamung beim Huhn unter Verwendung von Tiefgefriersperma und der intravaginalen Besamungstechnik., 1985, pp 136pp.
Abstract

363 ejaculates from 30 ganders were evaluated for semen colour, consistency and cloudiness, and the relationship between scores for the 3 traits with sperm concentration were investigated. White, dense ejaculates with a creamy consistency had a higher sperm concentration than cream- coloured or...

Zur instrumentellen Besamung von Hausgänsen: Vergleich für die Auswahl besamungstauglicher Ejakulate, 1992, pp 95 pp.
Abstract

From data collected over several years, it was shown that ejaculation of turkey ♂♂ 3 times per week (compared with 1, 2 or 5 times per week) yielded the highest ejaculate volume (0.92-1.04 ml) while maintaining sperm concentration and fertilizing ability. For ♂ fowls and ♂ geese, the corresponding...

Abstract

At 22 wk of age, ♂♂ and ♀♀ were transferred from floor pens to cages. For cocks ejaculated 3 and 5 times per wk, ejaculate volume averaged 0.89 and 0.83 ml resp., sperm concentration (spermatocrit value) 12.0 and 12.5%, sperm motility 80.2 and 80.2%, methylene blue reduction time 2.0 and 1.7 min,...

Abstract

In an appendix, data are given on 200 Pekin drakes; testis weight was < 30 g in 25.8% of ♂♂ and > 30 g in 74.2%, the range in weight being 1-98 g. Spermiogenesis was normal in 88%, poor in 5.5% and defective in 6.5% of ♂♂. The numbers of spermatozoa obtained from 14 drakes by massage 3 times...

Abstract

60 cocks and approx. 1200 hens belonging to the White Rock and New Hampshire breeds were used. 119 mixed semen samples were prepared from over 1500 ejaculates. The freezing method of Watanabe et al. [see ABA 38, 4363] was used. The forward motility of spermatozoa frozen by this method, and stored...

Abstract

When pooled semen from 40 males was diluted 1:1 in a solution containing 7.5% ethylene glycol, sperm motility averaged 71.0% v 81.1 for undiluted semen, egg fertility percentage 57.3 v 66.7, and the hatchability percentage of fertile eggs 77.8 v 78.6. Samples frozen to various temps. from -2 deg to ...

Abstract

The collection technique of Onishi was used [see ABA 24, 1354]. Over a 2-mth period, semen was collected 2 or 3 times weekly from 9 males . Ejaculate volume averaged 0.96 ml, sperm concentration (X103/mm3) 1.69, and forward motility 57.5%. The proportion of morphologically abnormal spermatozoa...
